Common Furnace Thermostat Problems

Do you ever feel like your thermostat is playing tricks on you? Does it turn the furnace off at strange times or make changes that leaveyou shivering in your living room? You may be dealing with a malfunctioning thermostat. Before panicking and shelling out money for professional repairs, it’s worth looking at what issues could be causing the problem.

In this blog post, we’ll cover some of the most common furnace thermostat problems and provide tips on troubleshooting them. That way, if you don’t need to call an HVAC technician, you can take care of the thermostat issue yourself!

Problem 1: Poor Temperature Regulation

Temperature regulation is how your thermostat maintains your home’s temperature at a set point. It is done via a heating, cooling, or HVAC system that regulates the temperature according to the programmed thermostat setting.

Poor temperature regulation can happen when the furnace or heating system runs more than it should, resulting in energy waste and higher electricity bills. It can also leave you feeling chilly in some rooms and too warm in others. Temperature regulation issues can result from both thermostat-specific and system-wide issues.

Possible causes

  • Thermostat placement: The location of your thermostat can play a significant role in your furnace’s temperature regulation, as it can be adversely affected by heat-generating and heat-dissipating sources like fireplaces, direct sunlight, and air vents. For instance, a thermostat placed too close to a sunny window may detect a higher temperature and shut off the furnace prematurely.
  • Clogged filters: Poor air circulation caused by clogged air filters can cause your furnace to overheat, resulting in poor temperature regulation. It can also make the heat distribution inconsistent.
  • Thermostat malfunction: A malfunctioning thermostat can lead to severe temperature regulation issues. A thermostat that cannot detect the indoor temperature correctly may continually run your furnace to maintain your set temperature.


The solution to poor temperature must start with thoroughly diagnosing the cause. Simply adjusting the thermostat settings won’t fix the problem. Here are some of the solutions:

  • Thermostat placement: You can avoid the interference of external sources by positioning the thermostat away from sources of cool or hot air. For example, a location that has reliable airflow is ideal for the thermostat.
  • Air filter replacement: Dirty air filters can lead to poor air circulation, make your furnace work harder, and cause temperature irregularities. Regular filter replacement is essential.
  • Thermostat repair or replacement: If you’ve tried other solutions and still experience poor temperature regulation, your thermostat may need repairs or replacement. Contact an HVAC technician to have it checked out.

Problem 2: Thermostat Display Issues

A blank thermostat display is a common issue that many homeowners face. It occurs when your thermostat display doesn’t show information like the current temperature or setting. A blank thermostat display can make adjusting the temperature challenging and lead to higher electricity bills. Several factors can cause a blank thermostat display, and fixing the problem requires identifying the underlying cause.

Potential reasons

  • Dead batteries: If your thermostat uses batteries, a dead battery could be responsible for a blank display.
  • Wiring problems: Wiring problems such as loose, disconnected, or damaged wiring can cause a blank thermostat display.
  • Tripped circuit breaker: A tripped circuit breaker can cause a blank thermostat display or shut off your entire HVAC system, rendering it useless.
  • Internal issue: A faulty component or malfunction on the internal circuit board can cause a blank display.


  • Replace batteries: If your thermostat uses batteries, replace them with fresh ones, and check if the display comes back on.
  • Check the wiring: Ensure all the wires are properly connected and free of corrosion, dirt, or other debris. If there’s a fault, reconnect the wires or hire a technician to fix it for you.
  • Check the circuit breaker: If you suspect the circuit breaker, turn it off and then turn it back on to see if the thermostat display comes back on.
  • Hire an HVAC technician: If none of the above solutions works, your thermostat may have an internal issue, such as a faulty component or circuit board. Contact an HVAC technician to diagnose and fix the problem.

Problem 3: Short Cycling

Short cycling is when your furnace turns on and off too often, causing inefficiencies and straining your HVAC system. It can lead to increased energy bills, reduced equipment lifespan, and decreased comfort levels in your home. Short cycling may occur for many reasons, but it should not be ignored, as it can lead to long-term HVAC problems.

Possible reasons

  • Oversized furnace: One of the primary causes of short cycling is a large furnace that heats an area too quickly, causing it to turn on and off frequently.
  • Clogged air filters: Clogged air filters can restrict airflow and cause your furnace to overheat, leading to short cycling.
  • Thermostat location: A thermostat in excessively hot or cold air, like the kitchen or direct sunlight, can cause your furnace to short cycle.
  • Malfunctioning thermostat: A faulty thermostat can detect the wrong temperature setting, resulting in your furnace turning on and off more often than it should.


  • Right furnace size: A furnace that’s too small for your house will struggle to heat it, while one that’s too large may lead to short cycling. Consult an HVAC expert to know the right size for your home.
  • Regular air filter replacement: Clean air filters allow for proper airflow and reduce the risk of short cycling. A regular air filter replacement schedule can help you avoid the problem.
  • Thermostat placement: Avoid placing thermostats in locations affected by cold or hot air drafts, direct sunlight, or a kitchen area to regulate temperatures.
  • Thermostat repair or replacement: If your thermostat is malfunctioning, get it repaired or replaced by an HVAC professional.


Furnace thermostats can have common issues that result in short cycling, blank display, and inconsistent temperatures. Identifying the underlying cause and taking preventive measures is essential to prevent long-term problems and keep your HVAC system functioning correctly. If you’re experiencing any common furnace thermostat problems, contact an HVAC professional for help. They will identify the source of the problem and recommend repair solutions to ensure reliable comfort levels in your home.

How to Install Return Air Duct in Wall?

When most individuals think about HVAC systems, they think about the air conditioner and furnace. While these machines play a vital part in the HVAC system, they do not circulate the conditioned air throughout your home. Instead, that is done by supply registers or return air ducts. That’s why you need to learn how to install return air duct in wall.

Return air ducts are essential in any HVAC system. They allow the conditioned air to return to the furnace or air conditioner so that it can be reheated or cooled and then sent back out into your home.

If you decide to replace or install a return air duct, this article will give you a thorough understanding of what to expect.

Why Install a Return Air Duct?

The main reason you need to install a return air duct in your home is because of the way an HVAC system functions. Conditioned air cannot simply go out into the room and be lost. It has to make its way back to the furnace or air conditioner to be cooled down again before being sent back through the air ducts.

If you do not install a return air duct, the conditioned air will go into another room instead of returning to the furnace or air conditioner. It can cause difficulties with your furnace because it has to work harder to heat the room, which is now colder than before. It will also create discomfort in that room because it has no supply registers bringing new, warm air inside it.

Where Should You Install a Return Air Duct?

The best place to install a return air duct is in the wall. It allows you to connect it to your furnace or air conditioner easily and keeps it out of the way.

If you choose to install the return air duct on the floor, you will have to run a tube or pipe from the duct to the furnace or air conditioner. It cannot be easy and can also take up a lot of space.

If you choose to install the return air duct in the ceiling, you will have to drill a hole in the roof and run a tube or pipe from the duct to the furnace or air conditioner. It can also be complicated and can cause water damage if not done correctly.

How Big Does a Return Air Duct Need to Be?

The size of your return air duct depends on the size of your furnace or air conditioner. A small system may only require a two to three-inch return air duct if you have a small system. Also, a more extensive air conditioner may need up to four or five inches in width for the return air duct.

When choosing the size of your return air duct, measure both vertically and horizontally across the front of your furnace or condenser unit. There are very few exceptions where you will need more than this measurement to find an appropriately sized return air duct.

How to Install The Return Air Duct?


  1. Decide where you want to install the return air duct. If you install it on the wall, you will have to drill a hole in the wall large enough for the duct to fit through.
  2. Cut a hole in the wall that is the same size as the return air duct. The hole should be two to three inches lower than the floor. If you place it on a higher level, you will have to run a tube or pipe from the duct to the furnace or air conditioner.
  3. Run a tube or pipe from the hole in the wall to the furnace or air conditioner. Securely fasten the tube or pipe to the wall and the furnace or air conditioner.
  4. Attach the return air duct to the tube or pipe. The duct should fit snugly onto the tube or pipe. If it does not, you can use metal bands to secure it in place.
  5. Connect the return air duct to the furnace or air conditioner. The duct should be securely attached to the furnace or air conditioner.
  6. Check the return air duct for any leaks or openings that may cause problems. If you notice any, seal them up immediately, so you do not lose conditioned air.
  7. Cover the hole in the wall with drywall and plaster. Make sure you completely seal the hole so no air can escape.
  8. Paint or decorate the wall around the return air duct to match the rest of your home.
  9. Test your return air duct installation by turning on your AC system and noting if it is working appropriately. Check the temperature levels, desired air pressure, and the operation of all filters and moving parts.

When Is It Time For An Air Conditioner Replacement?

Your air conditioner is a machine that takes hot air and cools it down. It’s also the machine that provides you with fresh, clean air in your home or office by removing stale and polluted air and replacing it with crisp and clean ones.

When this machine starts to break down, it can become more expensive than ever to replace – but there are steps you can take to prevent that from happening! Here we’ll look at how you may know when is the best time to get an air conditioner replacement and what your options may be.

AC Unit is Blowing Warm Air

Blowing warm air is usually a sign that something’s gone wrong with your AC unit. Your air conditioner may be blowing warm air rather than dispersing cool air. There are many possible causes such as:

  • Incorrectly set thermostat
  • Low refrigerant levels in your unit might indicate that it is not working correctly.
  • Your Outdoor Unit Lost Power
  • Your Evaporator Coils are Dirty

Another sign would be if the AC unit is blowing out cool air, but you can’t feel it. It typically means that there’s a problem with your thermostat, and it’s not wired correctly. If this happens, then call a professional to help you fix the issue ASAP!

Extremely Loud Noises From Outside Unit

If you’re hearing loud noises coming from outside of your home or office, and it sounds like your AC unit is trying to turn on, then the chances are high that something’s wrong with the compressor in your machine. The compressor makes the fan spin around really fast, so if you hear banging and rattling noises when turning on the AC, there might be something wrong with it.

The Air Flow is Not That Satisfying

It is another sign that you need to replace your air conditioner. If you’re not getting too great of airflow, but you know that it’s turned on and receiving electricity, then there might be something wrong with the internal system inside your machine, or there might be a clog in one of the hoses.

Air conditioners all have a condensing device that is usually found outside or inside a mechanical system. The air conditioner’s ability to cool down and function properly is affected by the accumulation of leaves and other debris. This negligence can also affect the performance of systems in the mechanical room, as equipment stored in the storage area can cause problems.

Excessive equipment and debris can cause the system to heat up, leading to a reduced airflow supply.

AC Thermostat is Not Functioning

If you turn on the AC but can’t seem to get it to blow cold air, be sure to check the thermostat first. Turn it up all the way and see if your machine responds. Sometimes, faulty wiring might cause this problem. If that doesn’t help, then try replacing the batteries in your AC’s thermostat.

Also, if your thermostat does not respond to the controls, it may be due to a low battery. The remote control buttons may also require repairs because of corrosion or damage from moisture and spills. If your AC is not cooling down after you make necessary troubleshooting, then replace the thermostat immediately!

You Can Hear Rattling and Clanging

Rattling and clanging noises coming from your AC unit typically means there’s a problem with the fan blades. Now, these things tend to last for years before they start to break down, but if you start noticing rattling and clanging when you turn on your AC, then the chances are high that something’s wrong with them.

Strange Odors When AC Turned On

If you notice strange odours when turning on your AC unit, this could be a sign of an issue with the coils in the machine. If these are damaged, then they will expel ammonia into the air. It typically means there’s something wrong with your freon levels inside of the system.

A foul smell coming from your AC unit may also mean that something has gone wrong with any of the filters or gaskets in your machine. It is essential to call a professional immediately if you start noticing any weird smells when turning on your AC unit!

Problems with the AC Are Occurring More Often


Typically the life of an AC is between 10 to 15 years. If you find that your unit is breaking down more often than it used to, this may mean that something’s wrong with it, and it might need to be replaced by a new one.

Of course, the older your AC unit gets, the more likely it is that you’re going to have issues with it. Things break down over time, and if you have a 15-year-old AC unit right now, the chances are high that it’s probably got some wear and tear on it and perhaps even some damage.

AC Unit Keeps Getting Clogged Up

If you’re constantly unclogging the vents in your home or office due to heavy dust buildup, then there’s a chance your AC unit needs a replacement. Now, this typically occurs when the AC units are older and have been in use for some time, but sometimes clogs can happen because of problems with installation or if someone makes a mistake when trying to install the machine.

Lots of Moisture and Leakage Around The Unit

If you notice that there’s lots of moisture or leakage around the unit, your unit is probably pretty old. It typically occurs because of rust building up around the tubing. Not only does this look bad for your home or office, but it could potentially cause further damage to the rest of the internal components in your AC system.

Leaks are common in older units, and sometimes they’re easy to see right away when oil seeps out from the machine. However, leaks can also occur internally due to constant use, breaking down internal parts within your air conditioner.

High Electricity Bill

If you notice that your electricity bill is getting relatively high, and it’s more than you remember paying last month, for example, then there’s a chance that something’s wrong with your AC. Perhaps the unit is broken and isn’t cooling as effectively as it used to.

Of course, if you’re running an AC 24/7 in your house or office, it’s going to be more expensive than usual. However, if you’re noticing that your bill is getting higher and higher each month for no reason at all, then there’s a chance that there might be something wrong with the machine.

Air Conditioner Replacement – Conclusion

So if you’re noticing any of the issues we’ve mentioned, then there’s a good chance that you need an air conditioner replacement. If this is the case, then it’s probably best to call a professional to come out and inspect your system for potential problems or check for any damage to the internal parts of your machine.

Also, make sure that you hire someone who knows what they’re doing. You don’t want someone coming out who doesn’t know how an air conditioner works!

What Temperature to Set Air Conditioner in Summer?

It is normal to turn on the air conditioner to make your home cool and comfortable in summer. Alongside the increasing temperatures, you’ll also have to deal with the high electricity bills as you would use your air conditioner more frequently. 

Although air conditioners provide the most efficient method of maintaining a comfortable indoor temperature, their effectiveness depends on several factors. It is essential to know what temperature to set air conditioner in Summer to ensure that an AC operates at optimal efficiency and reduces your energy bill.

What’s The Best Temperature to Set The AC in Summer?

To stay comfortable at home this summer, the U.S. Department of Energy suggests that you set your thermostat to 26C. In other words, if you have an AC with a thermostat at your home, set it to 26C. Even keeping the temperature 1 degree lower could improve the efficiency of your AC by about 8 percent.

Although there are several variances from location to location and many other factors that affect how efficient your AC will be this summer, a general rule would be that you should keep your AC between 25 degrees Celsius and 28 degrees Celsius in the summer months.

How to Maximize Cooling Efforts in Your Home?

Apart from knowing what temperature to set the air conditioner in summer, you can also maximize the cooling efforts at home by observing a few essential tips.

  • Consider using blinds and shutting your curtains if you reside in sunny regions of the world.
  • If you work with computers or other electronic appliances for long hours, ensure that you place them some distance away from the AC vent as they increase the temperature in a room.
  • Remember to clean the air ducts or replace filters once every month, as it ensures that your air conditioner operates at optimal efficiency by circulating all-new air.
  • The best time to use your AC is between 10 am and 4 pm, as this is when the core temperature is at its peak.
  • Install thermostats that have a programmable mode so that you can control the AC accordingly. For example, if it is winter, consider programming your AC to start four hours before coming home from work and switch off two hours after reaching home.
  • Although you can use AC throughout the day, ensure that you know how much power it is consuming. If you are not at home, shut down your AC.

What’s the Best Temperature to Guarantee Humidity Control?

Humidity control is another essential component of ensuring a comfortable work and living environment. As humidity levels in your home increase, the air becomes dense with water vapours. These vapours make it difficult for humans to breathe easily and cause several other condensations on walls.

Therefore, it becomes critical for you to consider what temperature to set air conditioner in summer and what temperature to set dehumidifier in summer. The recommended indoor humidity level is between 30% to 50%. Setting the air conditioner at a high temperature (at least 26C) and the dehumidifier at a slightly lower level (around 20C) is always better.

This way, you stay comfortable throughout the day and ensure that humidity levels are under control. You can measure humidity levels using an electronic hygrometer.

How to Save Energy While Enjoying Your AC This Summer?


Although an AC is a great device to beat the heat and enjoy your home this summer, it is also crucial to consider your electricity bill. Although you should set your AC at 26C, do not increase temperatures too much as it might unnecessarily increase the energy bills.

The following are some of the tips on how you can save energy while enjoying your AC this summer.

Avoid on/off cycles

Ensure that you are not setting an AC at very high temperatures and then switching it off for some time. Although the temperature inside your room might be higher than outside, you will still need to switch on the AC again when humidity levels rise rapidly. Therefore, instead of turning the AC on/off, set it at a permanent temperature.

Install programmable thermostats

If you don’t have programmable thermostats installed in your home already, consider installing them this summer. They will help you figure out when to switch on your AC and when not to use it so that you can save maximum energy and enjoy your AC this summer.

Use blinds and curtains

Although you might not notice it, the sunlight shining in your room heats everything inside, including walls, furniture, etc. Although blinds and curtains aren’t aesthetically pleasing, they can be beneficial in preventing your AC from working extra hard to lower the temperature of a room that’s full of natural light.

Set the thermostat at 26C

If you don’t have a programmable thermostat, ensure that you set the temperature of your AC to 26C and avoid increasing it much more than that as it might cause problems such as dampness in walls and other issues related to humidity levels.

Turn off the AC if you leave

If you are leaving your home for a vacation or work, turn off the AC and ensure that it remains shut as well. It will save energy and allow your AC to cool down before switching it back on when coming back from work/vacation.

Install outdoor covers on your AC

Although most people might not be aware of this fact, installing outdoor covers on your AC is advisable. It will ensure that the outdoor unit gets cooled down and prevented from overheating and also allow you to use your AC more efficiently.

Plan ahead

Instead of switching on your AC as soon as you reach home, it’s better to plan and set the temperature on your thermostat in advance. For example, if you are likely to get home by 5 pm, set the AC four hours before reaching home so that it cools your room quickly.

Switch your AC on when you are in a room

If possible, switch on your AC only when you are in the room to not cool empty rooms and lower humidity levels unnecessarily. You can increase humidity levels quickly by placing a pan of water on the floor and opening doors to other rooms.

What Temperature to Set Air Conditioner in Summer – Conclusion

It is essential to stay relaxed and comfortable throughout the summer months. You can achieve this by setting up your AC properly according to temperature levels throughout the day. It would be best if you also attempted to keep humidity levels under control as well. The tips mentioned above will surely help you achieve this goal without spending too much on electricity bills.

How Long Do AC Units Last?

Whether you plan to buy a new AC unit or think about maintaining your current AC, you may come across one question, “how long do AC units last?” It may be devastating to know that your comfort companion won’t last a lifetime.

An Air conditioner is a machine with multiple components and parts working together at the same time. It has a compressor, condenser coils, evaporator coil, refrigerant, motor, fans, etc. Each of these components requires proper care to function properly.

Those well-maintained AC units usually last 10 to 15 years. However, the home air conditioner’s lifespan varies based on several factors. Now, let’s deep dive into each aspect to learn more about how long AC units last!

What Affects the Lifespan of Your Air Conditioner?

When it comes to determining the lifespan of AC units, several factors will affect it. Let’s identify these factors below:

AC System Age – AC Systems have different average ages when they reach their half-life. For instance, a central AC system lasts 15 years, while window models stay around ten years.

Maintenance – The more you maintain your AC, the longer it will last. It is best to perform routine preventive maintenance at least once per year to ensure proper operation of the unit.

Usage – If you use your AC unit most of the time, you may reduce its lifespan by approximately 15% compared to being used sparingly.

Weather Conditions – The heat and humidity can harm an AC unit’s lifespan. Therefore, the more you use your air conditioner to battle against extreme climates, the sooner it will break down. It is especially true for areas that experience harsh weather conditions all year long.

Location/Climate – If you live in a mild climate and moderately use your AC most of the time, then chances are higher that it will last longer. A hot and humid location with abusive climate conditions such as hurricanes, tornadoes or forest fires with smoke damage may decrease the lifespan of your system.

Manufacturers/Models – When we talk about how long AC units last, manufacturers and models also play a significant role. Those AC units built with high-quality parts and materials may last longer than those with as many internal components to support durability. In general, the more expensive brands tend to last longer as compared to cheaper brands as well.

Size – AC units that are too big or too small will not function as efficiently compared to those with their temperature in a balanced range (not too cold and not too hot). It would be best to purchase an AC unit with the correct size based on the space it needs to cool down or heat up.

How to Extend Air Conditioner Lifespan?


There are many things you can do to help your air conditioner lasts long. However, it needs proper steps and techniques for a much better result! Here is a list of 7 tips that will help you increase your home air conditioner’s lifespan:

It would help if you changed filters monthly at least once a month to prevent dirt from accumulating inside the system as a routine practice. A clogged filter will reduce airflow, which means it will take longer for AC to cool the indoor environment even though you have set the desired temperature so high!

Standard air filters reduce airflow by up to 30%, whereas specially designed high-performance filters are available in the market, which reduces airflow by only 5%.

Cover outdoor units

If you have an outdoor unit, place a cover on it or provide shade covering during the summer months so that you won’t excessively expose your AC to heat and humidity outside. Also, outdoor units do not benefit from rainwater and wind blowing over them since they need stable temperatures for proper operation and deck drainage systems. 

Turn off the thermostat when not in use

Your thermostat is programmed to turn your AC off when it reaches a certain temperature set point, but you should turn off the thermostat when it is not in use. Also, adjust the temperature setting on your thermostat to ensure maximum energy efficiency.

Clean condenser coils

The build-up of dirt and dust on your unit’s outdoor coils reduces its ability to cool your home space properly. Clean or replace the evaporator coil annually for best results.

Perform regular maintenance

Performing regular maintenance on your AC will help it last longer. Clean or replace air filters, check refrigerant charge levels and perform all other recommended tasks as per manufacturer guidelines for optimum performance. In addition, avoid placing objects on top of the unit outside unless these are items that cover it from rainwater!

When is The Best Time to Replace Your AC Unit?

You can’t expect your AC unit to last forever, and there comes the point in time when it will start showing signs of wear and tear. Keeping up with regular maintenance can delay this process, but some AC units fail earlier than others, depending on how the owner takes care of it over their lifetime.

Here are a few signs that indicate you need to replace your home air conditioner:

  • Not as Efficient as It Used to Be
  • Costly repair bills
  • Frequent service calls
  • Excessive humidity inside your home

Heating & Air Conditioning Basics

Heating, ventilation, and air conditioning are known as HVAC. No matter where you live in the world, this will be a term that you frequently hear if you are involved in building structures or maintaining them. When it comes to keeping things comfortable in the home, few other inventions have been beneficial to humanity in indoor climates.

This article will help you understand the HVAC basics and some information about their inner workings, which should help with understanding why they work the way they do.

Heating and Cooling Systems

There are some standard heating and cooling systems that you should know. Every system has its price and uses. So, let’s take a look at the most common HVAC systems that we use.

Central system

The central system is the most common type of air conditioning and heating system. This system includes a furnace, an AC unit, ductwork, and vents where the air gets distributed throughout your home.

The advantage of this system is that it can heat and cool the entire home. The disadvantage is that it needs professional installation, so if you are not familiar with HVAC systems, it’s best to find a professional to do the job.

Heat pump

A heat pump is a combination of central heating and air conditioning systems. This system features one outdoor unit that provides both heating and cooling throughout the house. Hot water or electricity is used for heating while the cold air is conditioned and distributed via ductwork and vents throughout your home.


A furnace functions by blowing heated air via ducts that provide warm air to different areas of your house through grills or air registers. We call this kind of heating unit a forced warm-air or ducted warm-air distribution system. A furnace can work by natural gas, electricity, or fuel oil.

Air conditioner

Air conditioners offer cool air to the entire home, and they require a powerful fan or blower to distribute it evenly throughout your house via ductwork and vents.

Essential HVAC Components


All types of HVAC systems need a compressor and condenser to work. The compressor circulates the refrigerant, and this is what cools down your indoor unit. When it gets hot outdoors, the refrigerant absorbs heat from the air in your home or commercial building.

A condenser then rejects that heat outside through an exhaust system into the outdoors. Now let’s look at some essential parts of an HVAC system you should know about:

  • Indoor Unit: The indoor unit has a blower, coil, and fan for blowing and circulating air throughout your home and ductwork to distribute it properly. The fan blows out hot air while the coil absorbs water and releases cold air into your home.
  • Coil: Coils are from aluminum or copper tubing surrounded by the refrigerant. When the compressor circulates the refrigerant through the coils, the cooling process begins. It gives your home cool air to enjoy during warmer months.
  • Blower: A blower works with a fan to circulate cool air so you can enjoy it in every room of your home. Without a blower, you would not have enough cool air coming into your house to keep it comfortable enough.
  • Compressor: The compressor squeezes the refrigerant and sends it to your indoor unit’s coil. When the air passes over this coil, it cools down and gives your house a comfortable climate throughout the summer months.
  • Condenser: The condenser takes heat from the hot compressed gas before it goes back to the compressor, which means you get warm outdoor air for your home or building to enjoy during warmer months of the year.
  • Exhaust System: An exhaust system is made up of rigid metal ducting that releases hot air outdoors so you can have cooler indoor temperatures without having too high of electric bills for this to happen efficiently.
  • Filter: A filter helps take out dirt particles in your home, so you don’t breathe in harmful things that make you sick.
  • Inverter: Inverters are a reliable feature because they automatically change speeds according to need, saving you money on your electric bills when the AC is in use.

How Does an HVAC System Work?

Understanding how an HVAC system works starts with the different types of systems out there. We went over some basic facts about these systems, but let’s get down to the nitty-gritty on how these machines make your home comfortable all summer long.

When it comes to cooling down your home, you will need an indoor unit that has a blower fan and coil for absorbing moisture in incoming air so it can release cool air back into your house. Without this coil, your home would not have enough cool air to keep residents or workers feeling comfortable during warmer months of the year.

Most homes have ductwork built into their design that distributes this cool air throughout every room properly. If you are looking to improve airflow in certain parts of your house, you will need to make some minor changes like turning off the system and allowing the air to circulate back into the unit for a few minutes before turning it on.

Once your home or building has cooled down enough, your HVAC system will automatically shut off until hot air builds up again as temperatures outside cool down as well. This process happens throughout the day as needed—there’s no need to adjust any settings on your unit unless you want more airflow at certain times of day or night.

When it comes time to heat a space in the winter months, you will need an indoor unit with a fan and coil with a heating function. Most people have ductwork built directly into their design so warm air can get into their home or building without any problems.

Take the time to inspect your ducts for leaks and breaks to get the most heating power possible from your unit.

HVAC Basics – Conclusion

HVAC systems can vary depending on the type of system and heating or cooling it is to accommodate. Still, one thing is for sure—you will need a quality unit with quality parts to get your home comfortable all year long, so you don’t have to worry about breaking the bank when buying an air conditioner or heater.

This article is to introduce you to the HVAC basics. Most of us need a basic understanding of these systems before learning how to properly maintain our unit and keep it in good condition for years and years.

7 Tips for Reducing Your Cooling Costs

By now, most of us have gotten used to the fact that heating bills can be expensive in the winter. But what about those who live and work in warmer climates? Our air conditioning system is a significant source of home and office energy usage during the summer, and paying for it can hurt your wallet.

So if you live and work somewhere where it tends to get hot, what can you do? We’ve put together a list of options for reducing the energy your AC unit uses. Here are some of the ways to save big bucks on your cooling costs!

1. Install a Smart Thermostat

For those who want their temperature control to be as efficient as possible, installing a smart thermostat is the way to go. This type of thermostat allows you more control over your home or office’s temperature level.

Not only do these devices allow you to manually turn off and on your AC system when it isn’t needed, but they are also able to monitor the temperature in different places throughout your home. They can then adjust settings based on which rooms are hotter or colder, thus creating more even temperatures throughout the building.

Here are other benefits of using a smart thermostat:

  • Easy to install – Most models allow you to set the temperature and connect the device simply through your Wi-Fi.
  • You can control it from anywhere – Download an app on your phone, tablet, or computer and change the settings at work, school, or even while you’re vacationing!
  • They will reduce energy usage – Most models can learn from your behaviour and turn off when they sense no one is home.
  • Significantly lower cooling bills – Over time, a smart thermostat can save you as much as 15% on cooling costs.

2. Increase Your Thermostat Setting a Few Degrees

Can you comfortably raise the temperature on your thermostat by a few degrees? We understand that doing so can be difficult, especially for those who are cost-conscious. However, keep in mind that every degree higher you increase is equivalent to significant savings on your cooling costs.

Many people choose to turn the temperature on their AC down very low (such as 78 degrees) during scorching times of the day. While this saves money, you can save even more by turning it up a few degrees (like 82). An increase of just 4 degrees leads to savings of 10 percent or more on your cooling costs.

3. Add More Insulation

Here is something you might want to try for those who aren’t satisfied with their home’s insulation. Adding more insulation around the exterior walls of your house can drastically reduce the amount of time it takes for your AC unit to bring in cool air and send out hot air.

It can prevent your home from getting too hot during the day and help keep it colder at night. It is because insulation helps retain cool air inside your home for a more extended period than it would otherwise.

How does home insulation help reduce your cooling cost?

  • It helps prevent your AC from overworking – By not having to work as hard, insulation will extend the life of your home’s cooling unit.
  • It keeps out hot air – In turn, this means that heat doesn’t have anywhere to go but outside. On a hot day, this can make a huge difference.
  • In the long run, insulation is an investment worth making – You will be able to use your AC more as intended and reap the rewards of lower cooling bills each month as a result.

If you have been considering making changes to reduce your energy costs, adding insulation should be on the list.

4. Use Fans Strategically Throughout Your Home


Using fans strategically ensures that you’ll get more use out of them than just sitting in the corner of your room unused. For instance, consider placing a fan near a window that faces the direction where the wind usually blows.

By doing this, you can draw cool air into your home without having to turn on your AC system at all. And using ceiling fans is an excellent way to send hot air out of your house during the summer.

5. Limit the Use of heat-producing Appliances

If you cook a lot, then the chances are that your home will have lighting and ovens on throughout the day. While this may not seem like much, lighting and cooking can make your home feel hot.

So if possible, consider shutting off these appliances when they aren’t in use. It is crucial during the hours of the day where the sun shines directly into your windows, as it can cause quite a bit of excess heat to enter your room.

Here are some examples of heat-producing appliances:

  • ovens
  • microwaves
  • grills
  • dishwashers
  • washing machines
  • dryers

6. Conduct Frequent AC Maintenance

Taking good care of your AC system by having it checked for any problems each year can reduce cooling costs in several ways. For one thing, an AC unit that has just had its annual check-up probably uses less power than one that has no maintenance at all.

And if the system does have some issues with it, waiting to address them will cost you more money in the long run. Remember, a check-up today can save you lots of frustration and cash tomorrow!

7. Increase Your Air Conditioning System’s Efficiency

When choosing an air conditioning system for your home or office space, be sure to select one with high-efficiency ratings. Most AC units feature energy-efficient technologies such as heating coils and refrigerators, providing better cooling performance while using less energy.

Be sure to choose an AC system that fits appropriately for the layout of your building and for the climate in which you live or work. Oversized units also use more power than they should. A general rule of thumb that most contractors follow is that one ton of cooling capacity per 100 square feet of living space is sufficient.

Reducing Your Cooling Costs – Conclusion

Whether you are looking for ways to keep cool during the summer months or you want to save money on your energy bill throughout the year, there are plenty of simple changes that you can make within your daily routine.

By adding more insulation to your home, investing in more fans, limiting heat-producing appliances, you can see a significant difference in how much you can save on your cooling costs. Also, don’t forget to conduct frequent maintenance checks and increase the efficiency of your AC system.

How Often Should HVAC Be Replaced?


Many factors can affect the lifespan of your HVAC unit. The amount of usage, location, and climate conditions are just some examples. If you’re still not sure if it’s time to replace your unit, consider these key signs:

Source of food for rodents is easy to find

Rodents like raccoons and squirrels can infest your duct system, which typically leads to more severe issues. When this happens, you’ll be able to see rodent droppings and other debris around the unit.

HVAC smells strange

If your old system emits a strange smell, it could indicate mould or mildew growth inside the ductwork or even in the inner workings of the unit itself. An unclean system provides an excellent breeding ground for harmful bacteria and other microorganisms, making you sick when inhaled by humans. If you notice any unusual odours coming from your unit, it’s best to get it inspected right away.

HVAC equipment is ten years or older

If your unit is already ten years or older, then you should consider replacing it soon. On average, units last between 13 and 15 years before needing replacement. If your equipment is beyond this age bracket, repairing costs can be costly compared to the price of a new system.

Unusually high energy bills

Suppose you notice that your monthly energy bills are much higher than usual for no good reason. In that case, it’s time to have the HVAC unit inspected right away to look for any issues with airflow or lack thereof due to dirty filters causing poor air quality within the system. If technicians find no problems with airflow but your energy bills remain high, it could mean that it’s time to replace your current system.
