How Do I Size My Furnace?

When the time comes to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you pick a furnace oversized for your house, you’ll start to run into 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 a reduced life span and higher costs.

How can you be sure you know the right furnace size for your home? Get started with a load calculation from the professionals at Tokay. A load calculation takes particulars from your home into account and gauges 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 need to heat? Your 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 you’ll need. Let the professionals from Tokay evaluate 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 certain type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will have an impact on the heating and cooling needs of your home.
  • Outdoor Climate: Factor in the range of weather you receive in Lodi. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
