What size furnace do I need?

Installation

When the time comes to upgrade your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized properly for your home, will not only affect your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you select a furnace oversized for your home, you’ll start to notice 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 higher costs.

How can you be certain about the correct furnace size for your home? Begin with a load calculation from the team at McNatt Inc. A load calculation takes specifics from your home into account and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will be heating? The 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. Many times, it is more beneficial 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 will be necessary. Let the team from McNatt Inc take a look at 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 receive in Robstown. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
