This is a question we often hear from clients, and we’re here to provide some insight. For a 2,000 square foot home in Ontario, a high-efficiency furnace (95%+ efficiency) typically requires an output of 60,000 to 70,000 BTUs (British Thermal Units) per hour, according to guidelines from the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI). However, factors like your home’s insulation, age, and local climate can affect this estimate.
Why Furnace Size Matters
Choosing the right furnace size is crucial. An oversized furnace cycles on and off too frequently, causing wear and reducing efficiency. An undersized furnace works overtime, consuming more energy and struggling to maintain comfort.
Calculating Furnace Size
HRAI recommends 40 to 45 BTUs per square foot for colder climates. With high-efficiency furnaces, this requirement can be lower because they produce more usable heat for each BTU. For a 2,000 square foot home, this means around 60,000 to 70,000 BTUs.
