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When you need to replace your outdated furnace, it’s important to understand one size does not fit all.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 appropriately for your home, will not only hurt your comfort, but can result in shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a system oversized for your space, you’ll start to run into short cycles. This is because your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to shortened lifespan 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 experts at Northglenn Heating & Air Conditioning, Inc.. A load calculation takes specifics from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be accounted for during this process. Usually, 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 through the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the experts from Northglenn Heating & Air Conditioning, Inc. evaluate the insulation in your walls and attic. They’ll help you select the best 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Consider the range of weather you receive in Northglenn. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
