HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to replace your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized correctly for your home, will not only affect your comfort, but can mean a shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a unit oversized for your space, you’ll start to experience short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be confident in the right furnace size for your home? Begin with a load calculation from the experts at 1st Choice 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) necessary to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How large 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 needs to be accounted for during this process. Many times, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the team from 1st Choice Heating & Air Conditioning, Inc. review the insulation in your walls and attic. They’ll help you select the 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 get in Lake Forest. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
