What size furnace do I need?

When it’s time to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 spending extra money on your utility bills.

If you pick a system oversized for your home, you’ll start to notice short cycles. The reason is that 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 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 team at Alan Heating Air Conditioning, Inc.. A load calculation takes specifics from your home into account and gauges 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 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. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the experts from Alan Heating Air Conditioning, Inc. take a look at 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—Consider the range of weather you experience in Elmhurst. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
