What’s the Right Size Furnace for My Home?

In the cold winters of Pittsburgh, a furnace keeps your home nice and cozy throughout the season. If you are looking to replace your current furnace, you may be wondering what size furnace you should be looking for. At Restano Heating, Cooling, and Plumbing, we’ve put together some tips on how you can determine the right size furnace for your home. 

The Importance of Furnace Size

The size of your furnace is crucial. If you end up with a furnace that is too small for your home, you will have uneven heating and high energy bills. The furnace will also have a shorter lifespan because it is working harder to heat an area that it is not equipped for. 

If your furnace is too big, it can cause parts of your home to be sweltering hot and will also cycle on and off too frequently. This can also cause your furnace to wear out faster. 

Determining the Right Size Furnace for Your Home

Gas furnaces can be differentiated by their British Thermal Unit (BTU) capabilities. One BTU represents the amount of energy that is required to heat one pound of water by one degree Fahrenheit, so to determine the correct BTU for your home heating, you will need to make some calculations.

Find or Calculate the Square Footage of Your Home

The square footage of your home should be on the paperwork you received when you bought your house, or you should be able to reach out and ask your realtor. If you can’t determine the square footage from these options, then you can calculate the square footage yourself. 

Begin by measuring the length and width of each room in your home. Multiply the length and width of each room together. This will give you the square footage of each room. Once you’ve determined the square footage of each room, add them all together to get the square footage of your entire hour. It’s important to note that most furnace size charts assume that your ceilings are eight feet high. IF they are higher or lower than eight feet, be sure to adjust your measurements. 

When taking measurements, keep in mind that you do not need to measure rooms that do not have ductwork or that you don’t plan on heating, such as a sunroom. 

Consider Your Climate Zone

Pittsburgh customers live in a cold/very cold climate zone, so you will require a more powerful furnace than someone in California in a mixed dry or hot, dry climate zone. So you will be looking for a furnace that is more heavy-duty. 

Reference a Furnace Size Chart and Compare Your Measurement

There are a variety of furnace size charts available, and each of them gives you a comparison between home square footage and the BTUs required to heat the home. Many of the furnace size charts follow similar guidelines such as:

  • 1,200-square-foot home will require between 35,000 and 75,000 BTUs
  • 1,800-square-foot home will require between 45,000 to 90,000 BTUs
  • 2,100-square-foot home will require between 65,000 to 125,000 BTUs
