What size furnace do I need?

January 31, 2019

When the time comes to replace your outdated furnace, it’s important to understand one size does not fit all.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 with larger energy costs.

If you pick a system oversized for your house, 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 decreased lifespan and higher costs.

How can you be certain about the right furnace size for your home? Get started with a load calculation from the professionals at Discount Mechanical Heating & Plumbing Services. A load calculation takes specifics from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be considered during this process. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of 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 Discount Mechanical Heating & Plumbing Services review 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you get in Anchorage. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
