What size furnace do I need?

January 31, 2019

When you need to replace your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized properly for your home, will not only affect your comfort, but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you select a system oversized for your house, you’ll start to experience short cycles. This is because 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 reduced lifespan and cost you more in energy bills.

How can you be sure you know the correct furnace size for your home? Begin with a load calculation from the professionals at Airmen HVAC Service. A load calculation takes aspects from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will have to heat up? The 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 beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the professionals from Airmen HVAC Service take a look at the insulation in your walls and attic. They’ll help you select the ideal 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—Factor in the range of weather you get in Montoursville. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
