What size furnace do I need?

When you need to update your outdated furnace, it’s important to realize one size does not fit all.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 impact your comfort but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you select a system oversized for your home, you’ll start to run into short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to a shortened 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 professionals at Indoor Comfort Systems HVAC. A load calculation takes aspects from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) needed 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 accounted for during this process. Usually, it is more valuable to account only for the space that needs heating.
• Home Insulation—Insulation works to keep warm air from leaving your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the professionals from Indoor Comfort Systems HVAC review the insulation in your walls and attic. They’ll help you choose the perfect 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 receive in Croydon. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
