HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 affect your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a system oversized for your space, 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 shortened lifespan and bigger expenses.

How can you be sure you know the correct furnace size for your home? Get started with a load calculation from the professionals at Toptec Heating, Cooling, Plumbing & Electrical. A load calculation takes aspects from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will have to heat up? A 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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from leaving your home through the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Toptec Heating, Cooling, Plumbing & Electrical evaluate the insulation in your walls and attic. They’ll help you find a 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—Consider the range of weather you experience in Libertyville. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
