What size furnace do I need?

January 31, 2019

When the time comes to replace your outdated furnace, it’s important to understand one size does not fit all.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 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 house, you’ll start to experience short cycles. The reason is that your oversized furnace heated your home too quickly, 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 certain about the correct furnace size for your home? Start with a load calculation from the experts at Solar Air Inc. . A load calculation takes specifics from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will be heating? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be considered during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the experts from Solar Air Inc. evaluate 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Consider the range of weather you receive in Fort Lauderdale. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
