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When you need to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 properly for your home, will not only impact your comfort, but can result in shortened life of your furnace, and leave you with larger energy costs.

If you choose a system oversized for your home, you’ll start to experience short cycles. This is because 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 decreased lifespan and higher costs.

How can you be confident in the correct furnace size for your home? Begin with a load calculation from the professionals at Daniel's Heating & Refrigeration Corp.. A load calculation takes specifics from your home into account and identifies 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—What size is the area your furnace will need to heat? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to 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 escaping your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the professionals from Daniel's Heating & Refrigeration Corp. review the insulation in your walls and attic. They’ll help you choose the ideal furnace for your house.
  • Type of Window— Just like your walls, the particular 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 experience in Midlothian. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
