One of the questions homeowners ask when they install an AC unit is “how do I know if my AC is the correct size?”

The answer is a bit tricky.

Of course, you’ve got nothing to worry about if you hire a professional HVAC company to help you pick the unit and install it in your house. A professional HVAC company can help you choose the right size for your AC unit.

These professionals determine the appropriate size of your AC through a process known as cooling load calculation.

Cooling load calculation is one of the most crucial components of AC installation. If it isn’t properly done, it can result in an expensive HVAC repair down the line.

Today, we’re going to share with you the significance of properly sizing your AC unit.

What Happens if You Don’t Properly Size your Air Conditioner?

Think about your car’s engine. If the engine is too small, it will not power your vehicle to make it down the street or over a hill. Your vehicle can overheat if it is too late.

This can be applied to your AC unit. Your unit needs to cool your home properly. However, it should not damage the system.

Small AC Unit

If your AC unit is too small, it simply won’t cool your home to the level you require. You may even notice your AC running for a long period, yet your home is still not cool enough. Perhaps your unit is regularly tripping circuits or overheating due to how much energy it consumes.

Big AC Unit

Do you know what short cycling is? For those who don’t know, short-cycling is the process where an HVAC unit turns on for several minutes, then turns off again. This is very damaging to the unit and can cause a need for early replacement if you ignore the problem.

To make things simple, your AC unit is creating cool air too quickly if it’s too big for the house. This causes stress to particular parts of the unit while leaving other parts untouched.

This can be a costly issue to run into. Because of this, you should always hire a professional to install your unit to help you avoid this problem.

How Does Cooling Load Calculations Work?

If a professional HVAC technician size an AC unit for your house, they will look at a couple of factors. This includes the size of the room, the volume of air, and much more. They will consider other factors as well, such as what type of insulation you have, how high your ceilings are, how many windows and doors your home has, and much more.

These professionals utilize accurate measurements. They can figure out the size that your home needs using high-tech tools.

Because of this, you can guarantee that your AC unit is properly sized for your house if you hire a professional HVAC technician to install it.

If you want to install your AC unit on your own, there are tools online that can help you calculate the load size of your home.
