When the time comes to update your outdated furnace, it’s important to know that one size does not fit all.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 impact your comfort but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a unit oversized for your home, you’ll start to experience short cycles. The reason is that your oversized furnace heated your home too quickly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to a shortened life span and bigger expenses.

How can you be confident in the correct furnace size for your home? Begin with a load calculation from the experts at Farnell Heating & Air Conditioning Inc. A load calculation takes aspects from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—How big 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 needs to be included during this process. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from leaving your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the team from Farnell Heating & Air Conditioning Inc take a look at 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 particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will play into what heating and cooling needs your home requires.
  • Outdoor Climate—Think about the range of weather you experience in Mobile. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
