What size furnace do I need?

January 31, 2019

When the time comes to replace your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized appropriately for your home, will not only hurt your comfort, but can result in shortened life of your furnace, and leave you spending extra money on your utility bills.

If you pick a unit oversized for your home, you’ll start to notice 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 reduced lifespan and bigger expenses.

How can you be confident in the correct furnace size for your home? Get started with a load calculation from the team at PWA Heating & Cooling Inc. 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 house.

Some Things 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 may be considered during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the professionals from PWA Heating & Cooling Inc evaluate the insulation in your walls and attic. They’ll help you select the 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you receive in Plainfield. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
