HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 stuck with higher energy bills.

If you choose a unit oversized for your space, you’ll start to run into short cycles. The reason is that your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to shortened lifespan and cost you more in energy bills.

How can you be sure you know the right furnace size for your home? Begin with a load calculation from the experts at Oak Point Heating and Air LLC. A load calculation takes particulars from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? A 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. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping 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 you’ll need. Let the professionals from Oak Point Heating and Air LLC evaluate the insulation in your walls and attic. They’ll help you find a 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 get in Denton. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
