Choosing what size furnace to install can leave any homeowner frazzled. If you’re indecisive or just not sure about the best option, listen up. We’re here to lend an ear to your frustrations and help you determine the right furnace size for your home.
Why does furnace size matter?
It’s important to install an effective, energy-efficient setup to save on heating costs, maintain home comfort, and ensure system longevity. An appropriately sized furnace will heat your home gradually and maintain consistent temperatures. Installing an over- or undersized furnace puts unnecessary strain on the equipment—and your pocketbook.
If your furnace is too large for the home, it will short cycle, turning on and off in short sequences. Furnaces are designed to operate in intervals. An oversized furnace will generate too much heat for the space, and the thermostat will shut the system down early. Short cycling puts stress on the working parts, which could eventually cause the equipment to break down.
An undersized furnace will stay on longer than it is designed to, running continuously in an effort to heat the home. This results in a stressed system and higher energy bills. A small furnace may have a lower price tag up front, but in the long run, you may end up with an expensive repair bill when the heating system breaks down from too much wear.
How is furnace size measured?
Furnaces are measured in BTUs, or British thermal units, per hour. A BTU is the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. You can figure out the furnace size by calculating BTUs per square foot. One must also consider other factors like square footage, ceiling height, and climate.
The average 2,000 square foot home needs a furnace with 50,000 to 60,000 BTUs to heat properly. But you’ll need a professional’s help to factor in other variables, like the climate zone, ductwork, number of occupants, number of windows, sun exposure, amount and type of insulation, lighting placement, and more.
