How Do I Decide the Right Size of the Furnace For My Home?

Winters in Minnesota can be extremely cold, which is why it’s critical that you have a well-working furnace in your home. A furnace can’t fully operate if it’s not sized accordingly. In the article below, our St. Paul heating contractors help you determine the right size furnace for your home. 

Why is the Right Size Furnace Important?

Too small a furnace can lead to high energy bills, inconsistent heating, and shorter heating system lifespans. Not to mention the wrong size furnace won’t keep your Twin Cities home warm during the cold winters. A large furnace, on the other hand, may make parts of your home uncomfortably hot. It’s going to cycle on and off too much, which could cause your furnace to age. If you want to prevent these issues, you need to make sure you choose the right size furnace for your home.

Their BTU capability distinguishes gas furnaces. BTU stands for the British Thermal Units. One BTU reflects the amount of energy needed to heat one pound of water by one degree of Fahrenheit. You’re going to have to do a little math to calculate the right BTU you’re going to need for your home heating.

Calculate Your Furnace Size Using Square Footage

Your home’s square footage is a good way to determine the right size furnace. If you’re not sure exactly what your home’s size is, look up your home on Zillow or Redfin. Our friends at Gilmore Heating, Air and Plumbing, a heating contractor in Sacramento, say that most of the furnace size charts are based on eight-foot ceilings. If your ceilings are higher or lower, make adjustments to your calculations accordingly. To calculate furnace size by square footage, you take the square footage and multiply it by the furnace output. Continue reading to learn more about calculating furnace size.

Furnace Size

There are plenty of furnace size charts to choose from. Most of them will compare the home’s square footage, and BTU needed to heat the home. The following is a general guideline: 

  • 1,200 square foot home would take between 35,000 and 75,000 BTUs.
  • 1,500-square-foot home would take between 45,000 and 90,000 BTUs.
  • 1,800-square-foot home would take between 55,000 and 110,000 BTUs.
  • 2,100-square-foot home would take between 65,000 and 125,000 BTUs.
  • 2,400-square-foot homes would take between 75,000 and 145,000 BTUs.
