What size furnace do I need?

Installation

When you need to replace your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized properly for your home, will not only hurt your comfort, but can lead to shortened life of your furnace, and leave you with larger energy costs.

If you select a system oversized for your space, you’ll start to run into short cycles. This means 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? Begin with a load calculation from the team at O'Brien Heating & Air Conditioning. 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 space.

Some Items that Influence Furnace Size

  • Square Footage—What size 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 needs to be accounted for during this process. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep 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 O'Brien Heating & Air Conditioning take a look at the insulation in your walls and attic. They’ll help you select the 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you experience in Drexel Hill. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
