What size furnace do I need?

January 31, 2019

When you need to upgrade your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized properly for your home, will not only hurt your comfort, but can result in shortened life of your furnace, and leave you with larger energy costs.

If you choose a unit oversized for your home, 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 reduced 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 team at Cytech Heating & Cooling L.C.. A load calculation takes aspects from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—How big is the area your furnace will be heating? A 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. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the experts from Cytech Heating & Cooling L.C. review the insulation in your walls and attic. They’ll help you select 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you get in the Rio Grande Valley. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
