HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to upgrade your outdated furnace, it’s important to know that one size does not fit all.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 mean a shortened life of your furnace, and leave you stuck with higher energy bills.

If you select a furnace oversized for your space, you’ll start to experience short cycles. This is because your oversized furnace heated your home too quickly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to shortened lifespan and bigger expenses.

How can you be sure you know the right furnace size for your home? Start with a load calculation from the professionals at Keystone Heating & Air Conditioning Co., Inc. A load calculation takes specifics from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will need to heat? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be considered during this process. Many times, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home throughout the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the team from Keystone Heating & Air Conditioning Co., Inc evaluate the insulation in your walls and attic. They’ll help you choose the perfect furnace for your house.
  • Type of Window— Just like your walls, the specific type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Consider the range of weather you get in Racine. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
