When you need to replace your outdated furnace, it’s important to understand one size does not fit all.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

If you select a system oversized for your house, you’ll start to run into short cycles. The reason is that your oversized furnace heated your home too fast, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to a reduced life span and higher costs.

How can you be certain about the correct furnace size for your home? Get started with a load calculation from the experts at Custom Air Systems Inc. A load calculation takes particulars from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be accounted for during this process. Many times, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the team from Custom Air Systems Inc take a look at 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 particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you experience in Port St. Lucie. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
