What size furnace do I need?

January 31, 2019

When you need to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 mean a shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a unit 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 shortened lifespan and higher costs.

How can you be confident in the proper furnace size for your home? Start with a load calculation from the experts at Paso Robles Heating and Air. A load calculation takes aspects 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? The 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. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Paso Robles Heating and Air 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—Consider the range of weather you receive in Paso Robles. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
