The best way to determine the correct furnace size for your home is to choose a reputable installer. At Tetra, we calculate your home’s heating needs based on industry standards. These calculations take the climate and your home’s size, design, and construction into account. A furnace that’s too small for your home won’t keep your house comfortable in extremely cold weather. Most furnaces are slightly bigger than necessary to avoid this possibility, but a furnace that’s too large will cycle on and off more frequently. This causes wear and on the components, uncomfortable fluctuations in temperature, and noisy airflow—not to mention, it wastes a lot of energy.
A zone is an are in your home, which is controlled by its own thermostat. A home can have anywhere from 1-5 zones based on size, layout, or additions. Zoned HVAC uses dampers in the ductwork to regulate and redirect air to specific areas of the home.
Heat load is the amount of heat energy your home needs in order to maintain the desired indoor temperature. Your home’s heat load depends on its size, construction, insulation, number of windows, and other factors. The heat load will also determine the size and model of furnace your home needs. Speak to one of our experts about the new furnace cost and the best furnace for your home.
