What size furnace do I need?

January 31, 2019

When you need to update your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized correctly 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 select a furnace oversized for your space, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to shortened lifespan and higher costs.

How can you be confident in the correct furnace size for your home? Start with a load calculation from the team at Allstar Heating & Air Conditioning. A load calculation takes aspects from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Things that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be included during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving 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 Allstar Heating & Air Conditioning evaluate the insulation in your walls and attic. They’ll help you choose 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 Buellton. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
