What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 hurt your comfort but can result in shortened life of your furnace, and leave you with larger energy costs.

If you choose a furnace oversized for your space, you’ll start to run into short cycles. This is because your oversized furnace heated your home too fast, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to a shortened life span and cost you more in energy bills.

How can you be confident in the correct furnace size for your home? Begin with a load calculation from the professionals at Done Right Air. A load calculation takes particulars from your home into account and identifies 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 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 will be included during this process. Usually, it is more beneficial 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 heavily affects energy efficiency and how large of a heating system is required. Let the professionals from Done Right Air take a look at the insulation in your walls and attic. They’ll help you choose the 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 play into what heating and cooling needs your home requires.
• Outdoor Climate—Factor in the range of weather you get in West Allis & Milwaukee area. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
