When Should You Replace Your Furnace

 

Replacing your furnace is a great opportunity to increase your energy efficiency and comfort levels. Many times our technicians will ask how long it will take to install a new furnace. As long as your existing ductwork is intact and works correctly, it normally takes less than a day to replace an outdated furnace. However, there are decisions to be made before installation that can and should take some time.

Factors to Consider Before Installation

Combustion furnaces have an average lifespan of 15 to 20 years, so it’s important to make sure that you install a furnace that fits your needs and your home perfectly:

Size

Your home has specific heating needs, and these needs won’t be met if you install a system that is either too big or too small for your home. So how do properly size your furnace? By working with a trained professional on a heat load calculation. This calculation is comprised of things like:

  • Your home’s orientation
  • Levels of insulation
  • Floor plan
  • Number of occupants
  • Number and type of windows and doors
  • Square footage
  • Once the heat load calculation is done, you’ll know exactly what size furnace you’ll need to comfortable heat your home.

Type of Furnace

There are 2 main types of furnaces: electric and combustion. Combustion furnaces commonly use natural gas, but they can also use propane and oil. Electric furnaces can be good choices for homes that do not have immediate access to fossil fuels, or that don’t want to use a combustion system.

Energy Efficiency

Furnaces have become very energy efficient. The best way to check a furnace’s efficiency is to review its AFUE rating. The AFUE rating stands for annual fuel utilization efficiency, and it measures a furnace’s efficiency in converting fuel to energy. The higher AFUE rating, the greater energy efficiency of the furnace.

The installation of your furnace should be the last step of a process conducted with a trained expert. Taking these steps helps ensure that you’ll install a new furnace that will heat your home as you need it to for years to come.
