How to Choose the Right Size Air Conditioner for Your House

Purchasing an air conditioner for your house can be a costly expense. To avoid future issues, it’s crucial to choose the best unit for your needs and your home. Sizing is an extremely important feature to consider. When referring to the size of an AC unit, we are not talking about the dimensions like one would think. The size is actually the cooling capacity of the unit. Here are a few tips to help you determine the correct size and choose the right air conditioner for your home.

Measuring the room that the air conditioner will be cooling should be your first step. You can do this by simply multiplying the length times the width. If you are purchasing a central air conditioner, you will want to determine the square footage of each room of your home.

Once your final measurements are completed, you will need to calculate the cooling capacity. Cooling capacity is measured in BTU’s (British Thermal Units). How can you calculate how many BTU’s you will need? By visiting the United States Department of Energy, Energy Star website, you can find the guidelines for BTU’s per square footage.

As you can see, choosing the right size AC for your home is more involved than one may think. When it comes to HVAC, size is essential. If the tonnage of your unit isn’t just right, it could cause problems in the long run. At Affordable, we can help you choose the right unit for your home, as well as install all equipment. To save yourself time and money, reach out to the expert technicians at Affordable Service! We will get the job done in no time.
