What size furnace do I need?

When you need to update your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized appropriately for your home, will not only impact your comfort but can mean a shortened life of your furnace, and leave you with larger energy costs.

If you pick a unit oversized for your house, you’ll start to run into short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to a decreased life span and bigger expenses.

How can you be confident in the right furnace size for your home? Start with a load calculation from the professionals at Gilray Heating and Cooling. A load calculation takes particulars from your home into consideration 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 have to heat up? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be considered during this process. Many times, it is more useful to account only for the space that needs heating.
• Home Insulation—Insulation works to keep warm air from leaving your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the team from Gilray Heating and Cooling review 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 certain 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 Wausau. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
