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!



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.
