How do I size my furnace?

When the time comes to upgrade your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized correctly for your home, will not only hurt your comfort but can mean a shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a furnace oversized for your home, you’ll start to notice short cycles. This is because 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 a reduced life span and higher costs.

How can you be sure you know the correct furnace size for your home? Start with a load calculation from the experts at Knoechel Heating. A load calculation takes specifics from your home into consideration and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Items that Influence Furnace Size

• Square Footage—What size is the area your furnace will need to heat? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be included during this process. Many times, it is more beneficial to account only for the space that needs heating.
• Home Insulation—Insulation helps keep warm air from leaving your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system will be necessary. Let the experts from Knoechel Heating take a look at the insulation in your walls and attic. They’ll help you select the perfect furnace for your house.
• Type of Window—Just like your walls, the specific 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—Think about the range of weather you experience in Zelienople. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
