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When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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

If you pick a furnace oversized for your space, you’ll start to experience short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and cost you more in energy bills.

How can you be confident in the correct furnace size for your home? Start with a load calculation from the professionals at Jack's Heating, Cooling, Stoves & Fireplaces. A load calculation takes aspects from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? The 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 helps keep warm air from leaving 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 Jack's Heating, Cooling, Stoves & Fireplaces 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Think about the range of weather you experience in Alliance. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
