Are you searching the market for a new air conditioning system? Then it is very important to have a professional HVAC company involved in the process from the very beginning. This would be beneficial not just for the HVAC system’s installation but also for you to have the correct size of unit for your home. Although you must have heard the expression “bigger is better.” While this may be true for some pieces of equipment, it is not true for air conditioners. Selecting the wrong size air conditioner leads to many problems that are not easily fixed. Below we have explained why an Oversized Air Conditioner Is a Serious Problem
Problems With an Oversized Air Conditioner
Unfortunately, many homeowners end up purchasing an HVAC system that’s often too large for their homes to handle. A large air conditioner unit presents a number of problems that can be a nuisance. Resultantly, it can cause you to replace the unit years before its due time. Problems with an oversized air conditioner can affect your family for many years. Moreover, it can be costly to replace or fix. If the air conditioner is too small, it will not provide the cooling that your home needs. If it is too large, it causes its own set of problems such as:
Reduced Home Comfort
An air conditioner cools the air in your home. It also is responsible to suck out the moisture and humidity from the house. To remove the moisture, the air has to pass over an evaporator coil, which is a very cold surface. When the air passes over that coil, the air temperature can drop by as much as 20°F. When the temperature of the coil is below the air’s dewpoint, water vapor condenses on the surface of the coil.
However, if you have an oversized air conditioner installed, the air conditioning unit makes the room cool faster. As a result, it runs for a shorter period of time than an air conditioner that has been properly sized does. This means the water doesn’t condense on the coil and is carried back into the room. So although your room may be cooler, an oversized air conditioner results in that “sticky feeling. Thus it can be very uncomfortable for the inhabitants of the house.
Reduced Air Quality
Due to the increased level of moisture produced by a large air conditioner, the air quality in your home can deteriorate. This can be a big problem for anyone with asthma or any other respiratory disease.
Dust Mites and Mold
The growth of mold is also a reason why an Oversized Air Conditioner Is a Serious Problem. If the humidity level will be high, it will be easier for dust mites and mold to grab a foothold in your home.
Higher energy bills
As an oversized AC will often cool your home really fast and then shut off. This does not only wear out your AC components, but it can raise your energy bills too. An AC has several motors and all these motors draw in more power when they start up as compared to when they are running. So if your AC is turning on and off frequently, the motors in your AC are using more power than they should. This resultantly raises your energy bills.
So, if you’ve noticed steadily increasing energy bills, you may have an oversized air conditioner.
Noise
A properly sized air conditioner makes very little noise or most often runs silently. If your air conditioner sounds like a freight train when it turns on. That’s a sure sign the air conditioning unit is too big for the space. After all, You do not want to spoil the pleasure of your cool house on a warm summer’s day by having to listen to a very noisy air conditioning unit.
Short Cycling Issues
An oversized HVAC unit blasts your home with cool air instead of cooling it down gradually. These continuous temperature swings prompt your HVAC system to start up and shut down in rapid succession. This is a condition commonly known as “short cycling.”
Short cycling can wreak havoc on your HVAC system if left unchecked. The constant and abrupt starting and stopping can add unexpected wear and tear to the compressor, blower fan motor, and other HVAC components.
Money
An Oversized air conditioner costs more money than an appropriately-sized air conditioner. It also works inefficiently and may turn on and off several times throughout the day. Therefore, this costs more in terms of energy use, money, and wear and tear on the HVAC system. Greater use means more repairs and more money out of your wallet.
Structural Damage
Since a large air conditioner unit does not remove enough moisture and humidity from the air, the moisture is left behind. This accumulated moisture can have very serious consequences for your home. It can affect your home furniture, wood, walls, paint, etc.

- Similarly, mold in your home is also a sign that there is something wrong with your air conditioner.
- If you witness your wall paint beginning to peel in rooms where it feels particularly sticky, you should consult an HVAC technician. They will evaluate if the problem is an oversized air conditioner.
- Moreover, if you’re sneezing or coughing a lot when the air conditioning is on, this could be another sign.
- If you’ve noticed steadily increasing energy bills, you may have a wrong sized air conditioner.
- If someone in your home has asthma and you notice their breathing problems aggravate when the air-conditioning is running.
