What size furnace do I need?

When the time comes to update your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized appropriately for your home, will not only affect your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a unit oversized for your house, you’ll start to run into 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 cost you more in energy bills.

How can you be confident in the proper furnace size for your home? Get started with a load calculation from the professionals at PWA Heating & Cooling Inc. A load calculation takes particulars from your home into review and gauges 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 be heating? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be accounted for during this process. Many times, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from leaving your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system will be necessary. Let the team from PWA Heating & Cooling Inc review the insulation in your walls and attic. They’ll help you find a 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—Think about the range of weather you get in Plainfield. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
