HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 impact your comfort, but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you select a system oversized for your house, 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 reduced lifespan and higher costs.

How can you be sure you know the proper furnace size for your home? Begin with a load calculation from the professionals at Heartland Heating & Cooling. A load calculation takes aspects from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Things that Influence Furnace Size

  • Square Footage—What size 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 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 experts from Heartland 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you receive in Grimes. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
