What size furnace do I need?

January 31, 2019

When the time comes to upgrade your outdated furnace, it’s important to know that one size does not fit all.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 furnace oversized for your space, you’ll start to run into short cycles. This is because 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 decreased lifespan and bigger expenses.

How can you be confident in the correct furnace size for your home? Start with a load calculation from the team at Air Houston Mechanical LLC. A load calculation takes particulars from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will be heating? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be considered during this process. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to 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 you’ll need. Let the team from Air Houston Mechanical LLC take a look at the insulation in your walls and attic. They’ll help you choose the ideal furnace for your house.
  • Type of Window— Just like your walls, the particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you get in Huffman. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
