What size furnace do I need?

January 31, 2019

When you need to update your outdated furnace, it’s important to realize one size does not fit all.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 impact your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

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

How can you be sure you know the correct furnace size for your home? Start with a load calculation from the team at Goode Bros AC & Heating. A load calculation takes particulars from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Things 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. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the experts from Goode Bros AC & Heating review 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 get in Katy. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
