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When the time comes to upgrade your outdated furnace, it’s important to realize one size does not fit all.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 appropriately for your home, will not only affect your comfort but can mean a shortened life of your furnace, and leave you with larger energy costs.

If you select a furnace oversized for your home, you’ll start to experience short cycles. This is because 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 certain about the right furnace size for your home? Start with a load calculation from the professionals at Diedrick's Heating and Air Conditioning. A load calculation takes aspects from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

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 needs to be considered during this process. Often, it is more useful 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 strongly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Diedrick's Heating and Air Conditioning evaluate the insulation in your walls and attic. They’ll help you find a ideal 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 influence your heating and cooling requirements.
• Outdoor Climate—Consider the range of weather you get in Seymour. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
