HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to update your outdated furnace, it’s important to understand one size does not fit all.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 spending extra money on your utility bills.

If you choose a furnace oversized for your space, you’ll start to run into short cycles. This is because your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be sure you know the correct furnace size for your home? Get started with a load calculation from the team at ACS Heating and Air Conditioning. A load calculation takes particulars from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Items that Influence Furnace Size

  • Square Footage—How large 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. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from filtering out of your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the experts from ACS Heating and Air Conditioning review the insulation in your walls and attic. They’ll help you find a perfect furnace for your house.
  • Type of Window— Just like your walls, the specific 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—Think about the range of weather you experience in Tucker. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
