HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to update your outdated furnace, it’s important to understand one size does not fit all.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 appropriately for your home, will not only hurt your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a system oversized for your home, 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 the right operating temperatures. An undersized or oversized system can lead to decreased lifespan and bigger expenses.

How can you be certain about the proper furnace size for your home? Begin with a load calculation from the experts at Woody's Sudden Service Inc. A load calculation takes specifics from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will be heating? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be included during this process. Many times, it is more valuable 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 will be necessary. Let the experts from Woody's Sudden Service Inc take a look at the insulation in your walls and attic. They’ll help you select 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you receive in Manassas Park. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
