How to Size an Air Conditioner for Your Home According to Experts 

The air conditioner you choose for your home must be adequately sized to do its job properly. An oversized unit can lead to frequent cycling, while an undersized one may struggle to cool your home effectively. Worst of all, an improperly sized unit will cost you more in utilities and wear and tear in the long run. Here, our team explains how to accurately determine the appropriate size for your air conditioner. 

Understanding AC Unit Measurements 

First, how is the size of an AC unit measured? 

Air conditioners are measured in tons or British Thermal Units (BTUs). One ton of cooling capacity equals 12,000 BTUs. Generally, a one-ton unit is suitable for cooling about 750-1,000 square feet. Here’s a quick guide: 

  • 1.5 Tons (18,000 BTUs): Suitable for 1,000-1,500 square feet 
  • 2.0 Tons (24,000 BTUs): Suitable for 1,500-2,000 square feet 
  • 2.5 Tons (30,000 BTUs): Suitable for 2,000-2,500 square feet 

For instance, a 2,000-square-foot home typically requires a 2.0 – 2.5-ton air conditioner. 

Factors to Consider 

While the size of your space is a primary factor, other characteristics of your home also influence the ideal AC size: 

  • Layout: Open floor plans might require different cooling capacities compared to segmented layouts. 
  • Insulation: Well-insulated homes retain cool air better, potentially reducing the required AC size. 
  • Sunlight Exposure: Homes with significant sun exposure may need a larger unit to compensate for the added heat. 

Consulting with an HVAC Professional 

For the most accurate recommendation, consult with an HVAC professional. They can perform a detailed analysis of your home’s specific needs, considering additional factors such as: 

  • Home Orientation: The direction your home faces affects cooling needs. 
  • Window Size and Type: Larger or less efficient windows can increase cooling requirements. 
  • Local Climate: Canadian climates vary significantly, impacting the cooling load. 

After measurements are taken and your home is assessed, a professional can give you the best estimate of the AC size you need.
