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When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all.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 appropriately for your home, will not only affect your comfort, but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a system oversized for your home, you’ll start to notice short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and higher costs.

How can you be confident in the correct furnace size for your home? Start with a load calculation from the team at Northern Comfort Inc. A load calculation takes particulars from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—How big is the area your furnace will need to heat? A 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 useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping your home during the cold winter months. It also heavily affects energy efficiency and how large of a heating system will be necessary. Let the experts from Northern Comfort Inc review the insulation in your walls and attic. They’ll help you find a 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Consider the range of weather you experience in Mankato area. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
