HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to update your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized appropriately for your home, will not only affect your comfort, but can mean a shortened life of your furnace, and leave you with larger energy costs.

If you select a furnace oversized for your house, you’ll start to experience short cycles. This means your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to decreased lifespan and higher costs.

How can you be confident in the proper furnace size for your home? Begin with a load calculation from the experts at West Jefferson Plumbing and Heating, Inc.. A load calculation takes aspects from your home into consideration and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—What size 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 may be considered during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home throughout the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the team from West Jefferson Plumbing and Heating, Inc. evaluate the insulation in your walls and attic. They’ll help you find a best furnace for your house.
  • Type of Window— Just like your walls, the certain type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you experience in West Jefferson. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
