When you need to update your outdated furnace, it’s important to know that one size does not fit all.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 unit oversized for your home, you’ll start to run into short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to a decreased life span and higher costs.

How can you be certain about the correct furnace size for your home? Begin with a load calculation from the experts at Olde Towne Heating & Air. A load calculation takes aspects 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 Things that Influence Furnace Size

  • Square Footage—How large 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 may be accounted for during this process. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Olde Towne Heating & Air evaluate 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 influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you get in Mount Pleasant. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
