What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 result in shortened life of your furnace, and leave you with larger energy costs.

If you pick a system oversized for your space, you’ll start to run into short cycles. This means 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 reduced lifespan and higher costs.

How can you be sure you know the correct furnace size for your home? Get started with a load calculation from the professionals at Willco Air Conditioning, Refrigeration & Heating Inc.. A load calculation takes aspects from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will need to heat? The 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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping 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 professionals from Willco Air Conditioning, Refrigeration & Heating Inc. evaluate the insulation in your walls and attic. They’ll help you choose 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 experience in Branchville. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
