HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to update your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized appropriately for your home, will not only impact your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a furnace oversized for your house, you’ll start to notice short cycles. This means 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 cost you more in energy bills.

How can you be sure you know the correct furnace size for your home? Begin with a load calculation from the experts at Vogts Heating & Air. 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 home.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will have to heat up? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be accounted for during this process. Often, 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 greatly affects energy efficiency and how large of a heating system will be necessary. Let the experts from Vogts Heating & Air 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 influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you get in Pocatello. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
