How to Determine Air Conditioner Size for Your Home


It’s extremely important to install the right air conditioner size in your home. A system that is too big (or too small) can be prone to premature wear and tear, breakdowns, higher energy bills and uneven cooling. The best way to determine what AC size you need is to have a certified professional calculate the cooling load of your home and recommend the right system for your needs and budget.

When considering the right air conditioner size for your home, a trained cooling specialist will take into account factors such as:

  • Liveable square footage
  • Current layout or future layout of the home
  • Heat producing appliances that are installed
  • Age of the home
  • Home construction (brick, vinyl, etc)
  • Weather conditions and the amount of direct sun exposure
  • Quality and number of windows.

After a thorough walkthrough of your home, they’ll be able to determine the best air conditioner size for your home.

Choose a Reputable Installation Company
Before deciding to update your air conditioner, make sure you hire a reputable company. The best cooling system will not perform as it should if it’s improperly installed. Ensure the company does its own work—not subcontract—and all their technicians are professionals and certified.
