HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 affect your comfort, but can lead to 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 run into short cycles. This is because your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to reduced lifespan and cost you more in energy bills.

How can you be sure you know the correct furnace size for your home? Start with a load calculation from the team at D & D Heating & AC. A load calculation takes particulars from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? The 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 assists in keeping warm air from filtering out of your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the professionals from D & D Heating & AC evaluate the insulation in your walls and attic. They’ll help you choose 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—Think about the range of weather you experience in Brighton. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
