What size furnace do I need?

January 31, 2019

When the time comes to update your outdated furnace, it’s important to know that one size does not fit all.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 hurt your comfort, but can mean a shortened life of your furnace, and leave you stuck with higher energy bills.

If you select a furnace oversized for your space, you’ll start to notice 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 shortened lifespan and bigger expenses.

How can you be confident in the correct furnace size for your home? Get started with a load calculation from the experts at Aggressive Mechanical. A load calculation takes aspects from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Things 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 will be included during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home during the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the professionals from Aggressive Mechanical review 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—Factor in the range of weather you get in Neptune City. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
