When the time comes to replace your outdated furnace, it’s important to know that one size does not fit all.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 affect 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 run into short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to a reduced life span and higher costs.

How can you be confident in the right furnace size for your home? Begin with a load calculation from the professionals at May's Heating & Air. A load calculation takes specifics from your home into account and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Things 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 included 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 heavily affects energy efficiency and how large of a heating system you’ll need. Let the professionals from May's Heating & Air 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 certain 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 experience in Frederick. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
