When it’s time to replace your outdated furnace, it’s important to realize one size does not fit all.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

If you choose a furnace oversized for your home, you’ll start to notice short cycles. This is because your oversized furnace heated your home too fast, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to a reduced life span and bigger expenses.

How can you be certain about the correct furnace size for your home? Start with a load calculation from the experts at May's Heating & Air. A load calculation takes specifics from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will have to heat up? Your 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. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the experts from May's Heating & Air evaluate the insulation in your walls and attic. They’ll help you choose the best 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—Think about the range of weather you receive in Frederick. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
