What size furnace do I need?

January 31, 2019

When it’s time to update your outdated furnace, it’s important to understand one size does not fit all.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

If you pick a system oversized for your home, 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 correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and cost you more in energy bills.

How can you be certain about the correct furnace size for your home? Start with a load calculation from the experts at I-Deal HVAC. A load calculation takes aspects from your home into consideration and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How large 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. Often, it is more beneficial 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 you’ll need. Let the experts from I-Deal HVAC review the insulation in your walls and attic. They’ll help you choose the 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 influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you get in Albuquerque. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
