When you need to upgrade your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized properly 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 select a unit oversized for your home, you’ll start to notice short cycles. The reason is that 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 shortened life span and cost you more in energy bills.

How can you be confident in the right furnace size for your home? Start with a load calculation from the professionals at Farnell Mechanical, Inc.. A load calculation takes aspects from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How large 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 may be included during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from filtering out of your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the team from Farnell Mechanical, Inc. take a look at the insulation in your walls and attic. They’ll help you find a best 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 influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you receive in Auburn and Opelika. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
