HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to upgrade your outdated furnace, it’s important to realize one size does not fit all.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 hurt your comfort, but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a system oversized for your home, you’ll start to run into short cycles. This is because your oversized furnace heated your home too fast, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to decreased lifespan and higher costs.

How can you be certain about the correct furnace size for your home? Get started with a load calculation from the experts at Cronin-Verheul Heating & A/C Ltd. A load calculation takes aspects from your home into consideration and gauges 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 big 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 considered 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 escaping your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the team from Cronin-Verheul Heating & A/C Ltd evaluate 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you experience in Waterloo. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
