What size furnace do I need?

January 31, 2019

When the time comes to replace your outdated furnace, it’s important to realize one size does not fit all.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 impact 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 space, you’ll start to notice short cycles. This means your oversized furnace heated your home too rapidly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to shortened lifespan and cost you more in energy bills.

How can you be certain about the correct furnace size for your home? Start with a load calculation from the experts at Speedy Air Conditioning. A load calculation takes aspects from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How big is the area your furnace will have to heat up? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be included 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 greatly affects energy efficiency and how large of a heating system will be necessary. Let the team from Speedy Air Conditioning evaluate the insulation in your walls and attic. They’ll help you select the 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—Factor in the range of weather you get in Naples. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
