Furnace Sizing in Ontario, OR

When you have a new furnace installed, it’s very important you have one installed that’s the right size for your property. There’s a calculation you can perform that will give you a good idea of which sized unit is right for your home.

Determine Your House’s Square Footage

You need to know the square footage of your home to get the right-sized furnace. You can find this on the appraisal you got for the property when you bought it. It may also be available on your county assessor’s website. If these documents aren’t available, you’ll need to calculate the square footage yourself using a tape measure. Measure each room, and then add them together.

Stan’s Heating, Inc in Ontario, OR, can help you determine the right furnace for your house. We’ve been installing furnaces since 1981.

Find Your Climate Zone

The US Department of Energy created a map that shows which climate zone you live in. Homes in areas with colder climates need more powerful furnaces than those in warmer climates. Ontario is in climate zone 5. This means the furnace you choose needs to have 50-60 heating BTUs per square foot of your house.

Calculate the Furnace Size You Need

Multiply the square footage of your home by the climate zone factor for your area. For instance, if your house is 2,000 square feet, you need a furnace that has 100,000 to 120,000 BTUs. You can fine-tune this number using other characteristics of your home as well.

If your home has good insulation, you should get a furnace closer to 100,000 BTUs. An old, leaky house will need one closer to 120,000 BTUs. If your residence has a lot of windows, you need a furnace with more capacity than one with fewer windows.
