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When you need to replace your outdated furnace, it’s important to realize one size does not fit all.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

If you choose a furnace oversized for your home, you’ll start to run into short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to decreased lifespan and cost you more in energy bills.

How can you be sure you know the right furnace size for your home? Get started with a load calculation from the team at Tri County Air Care LLC. A load calculation takes particulars from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Factors 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 will 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 filtering out of your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the team from Tri County Air Care LLC 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you experience in Dallas. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.

Don’t settle for ‘close enough’ when choosing your new furnace. Let the professionals at Tri County Air Care LLC help you find a system that will fit your home properly.
