Proper furnace sizing plays a crucial role in ensuring the efficient operation and overall comfort of your home. An oversized furnace can result in a phenomenon known as short cycling, which not only accelerates wear and tear on the system but also reduces its long-term efficiency. On the other hand, an undersized furnace may run continuously in an effort to maintain a comfortable temperature, leading to higher energy consumption. To determine the right furnace size, the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) recommends a range of 30 to 45 BTUs per square foot for high-efficiency furnaces in colder climates. For instance, a 5,000 square foot home typically requires between 150,000 and 225,000 BTUs. However, since most single-unit furnaces top out around 120,000 BTUs, a two-furnace setup might be necessary.
While these general guidelines are helpful, a more accurate assessment of your home's heating needs can be obtained through a professional load calculation. This calculation takes into account various factors that affect heating requirements, such as insulation levels, window characteristics, construction type, ceiling height, and local climate. In regions like Ontario, known for its severe winters, HVAC experts like Affordable Comfort can conduct these load calculations following HRAI's recommendations, ensuring an accurate furnace sizing recommendation for your specific needs.
