HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized correctly for your home, will not only impact your comfort, but can result in shortened life of your furnace, and leave you with larger energy costs.

If you select a furnace oversized for your space, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be sure you know the correct furnace size for your home? Begin with a load calculation from the experts at Gee & Missler Heating & Air Conditioning. A load calculation takes specifics from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be considered during this process. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the professionals from Gee & Missler Heating & Air Conditioning evaluate the insulation in your walls and attic. They’ll help you select the best furnace for your house.
  • Type of Window— Just like your walls, the certain type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you receive in Wyandotte. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.

Don’t settle for ‘close enough’ when selecting your new furnace. Let the professionals at Gee & Missler Heating & Air Conditioning help you identify a system that will fit your home properly.
