What size furnace do I need for a 1,500 square foot home? This is a question we get asked on a regular basis by clients. For a 1500 square foot home in Ontario, when considering high-efficiency furnaces (95%+ efficiency), you’ll typically need a furnace with an output between 45,000 and 67,500 BTUs (British Thermal Units) per hour, according to guidelines from the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI). However, this can vary based on factors such as your home’s age, insulation, and local climate.

Choosing the right furnace size for a 1500 square foot home can be a complex task, especially given the diversity of high-efficiency options available in the market. At Affordable Comfort, we recognize the importance of accurately sizing your furnace for maximum efficiency, durability, and comfort.

Why Furnace Size Matters

Understanding furnace sizing is critical because an improperly sized furnace can lead to various problems. An oversized furnace will cycle on and off frequently, leading to increased wear and tear and decreased efficiency. Conversely, an undersized furnace will constantly run, trying to meet your heating needs, leading to excessive energy consumption and potential comfort issues.

Calculating Furnace Size

Furnace sizes are generally measured in British Thermal Units (BTUs). The BTU rating indicates the amount of heat the furnace can produce per hour. HRAI’s general rule of thumb suggests 40 to 45 BTUs per square foot of your home in colder climates. However, this is a rough estimate and assumes average efficiency furnaces.

When considering high-efficiency furnaces with efficiency ratings of 95% or higher, the BTU requirement can be lower. For a 1500 square foot home, this calculation would suggest a requirement of around 45,000 to 67,500 BTUs. This figure factors in that high-efficiency furnaces waste less heat, meaning you get more usable heat for each BTU.
