When it’s time to upgrade your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized properly 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 furnace 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 a shortened life span and cost you more in energy bills.

How can you be confident in the correct furnace size for your home? Start with a load calculation from the experts at Kohles & Bach Heating & Cooling. A load calculation takes aspects from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) necessary 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 will be included during this process. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the team from Kohles & Bach Heating & Cooling review 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 get in Des Moines. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
