Would you buy a car without researching what features it offers? Selecting and installing a new HVAC unit for your home can be much like the car-buying experience. You need to make sure you take inventory of your needs in order to choose the HVAC unit that’s right for you.


What size unit do you need?

You wouldn’t buy a two-seater car if you have a family of four, so don’t buy an air-conditioning unit that is too small for your home. Selecting the proper size air-conditioning system is critical to ensuring the adequate cooling of your home.


You need to make sure you have an accurate measurement of the spaces the unit will be cooling. You may want to reference your current property appraisal or use an online real-estate app, such as Zillow or Realtor.com, to get a rough estimate. If you’ve added space to your home since the appraisal was conducted, be sure you include that added square footage to your total number.


Air-conditioning units are sold according to tons. The general rule is for every 500-600 square feet, one ton of cooling is required. Units range from 1.5 tons to 5 tons. Once you determine the accurate square footage of your home, you also need to consider your geographic location.  


Where do you live?

A convertible car would make more sense if you lived in Florida rather than Alaska. Consider how many months you will be cooling your home and for how long each day.


BuyAirDirect’s Sizing Guide can help you select the proper size air-conditioning unit based on the square footage of your home combined with your geographic location.


How old is your unit?

If you have an old HVAC system that uses R-22 refrigerant, it’s best to make plans now to have your system replaced. The U.S. Environmental Protection Agency is phasing out the importation of this chemical coolant, and by January 1 of 2020, it will no longer be allowed into the U.S. This means that if you have an old system that uses this outdated refrigerant, it will be hard to find when your unit needs repairs and high in cost because of the drastic shortages.
