HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to upgrade your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized properly for your home, will not only impact your comfort, but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a system oversized for your space, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too fast, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be sure you know the right furnace size for your home? Get started with a load calculation from the experts at KDM Service Corporation. A load calculation takes aspects from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) needed 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 needs to be included during this process. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the experts from KDM Service Corporation take a look at 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—Think about the range of weather you experience in Tuscaloosa. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.

Don’t settle for ‘close enough’ when choosing your new furnace. Let the qualified technicians at KDM Service Corporation help you pick a system that will fit your home properly.
