HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to replace your outdated furnace, it’s important to know that one size does not fit all.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 result in shortened life of your furnace, and leave you spending extra money on your utility bills.

If you pick a unit oversized for your home, you’ll start to experience 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 higher costs.

How can you be sure you know the right 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 measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? A 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. Many times, it is more useful 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 experts from PWA Heating & Cooling Inc review 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you get in Plainfield. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
