HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 with larger energy costs.

If you choose a system oversized for your home, you’ll start to experience short cycles. The reason is that your oversized furnace heated your home too fast, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to shortened lifespan and bigger expenses.

How can you be confident in the proper furnace size for your home? Begin with a load calculation from the team at Strine's Heating & Air Conditioning. A load calculation takes specifics from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How big is the area your furnace will be heating? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be accounted for during this process. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the professionals from Strine's Heating & Air Conditioning evaluate the insulation in your walls and attic. They’ll help you choose the ideal furnace for your house.
  • Type of Window— Just like your walls, the particular 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 get in York. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
