HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 hurt your comfort, but can mean a shortened life of your furnace, and leave you with larger energy costs.

If you pick a furnace 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 higher costs.

How can you be confident in the right furnace size for your home? Start with a load calculation from the experts at Clean Air HVAC. A load calculation takes particulars from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Things 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 needs to be considered 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 heavily affects energy efficiency and how large of a heating system is required. Let the experts from Clean Air 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you receive in Pacheco. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
