HVAC Contractor helping a couple choose a furnace

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When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 appropriately for your home, will not only hurt your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a system oversized for your space, you’ll start to experience short cycles. This means 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 shortened lifespan and bigger expenses.

How can you be certain about the proper furnace size for your home? Start with a load calculation from the team at Carefree Heating and Cooling, LLC. 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 house.

Some Items that Influence Furnace Size

  • Square Footage—What size 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. Many times, it is more beneficial 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 strongly affects energy efficiency and how large of a heating system is required. Let the professionals from Carefree Heating and Cooling, LLC take a look at 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you receive in Hamilton. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
