When you need to update your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized appropriately for your home, will not only hurt your comfort but can mean a shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a furnace oversized for your house, you’ll start to run into 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 a shortened life span and bigger expenses.

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

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will be heating? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be considered during this process. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping 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 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you experience in Frederick. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
