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When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 properly for your home, will not only impact your comfort but can lead to 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. The reason is that 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 reduced life span and bigger expenses.

How can you be sure you know the proper furnace size for your home? Start with a load calculation from the team at JTech Mechanical. A load calculation takes aspects from your home into consideration and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your home.

Some Factors that Influence Furnace Size

• Square Footage—What size is the area your furnace will be heating? 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. Often, it is more useful to account only for the space that needs heating.
• Home Insulation—Insulation helps keep warm air from escaping your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the team from JTech Mechanical review the insulation in your walls and attic. They’ll help you select the ideal 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 Magnolia. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
