What size furnace do I need?

When you need to update your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized properly for your home, will not only affect your comfort but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a unit oversized for your space, you’ll start to experience short cycles. The reason is that your oversized furnace heated your home too fast, turning off before the furnace can reach the right 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 sure you know the proper furnace size for your home? Start with a load calculation from the team at TopTec. A load calculation takes specifics from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Items that Influence Furnace Size

• Square Footage—What size is the area your furnace will have to heat up? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be accounted for during this process. Many times, it is more useful to account only for the space that needs heating.
• Home Insulation—Insulation helps keep warm air from leaving your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system you’ll need. Let the team from TopTec 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 have an impact on the heating and cooling needs of your home.
• Outdoor Climate—Factor in the range of weather you experience in Libertyville. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
