furnace replacement

Are you thinking about furnace replacement,  but are unsure if it’s the right time? Age, cost of repair and the energy efficiency of your furnace all factor into whether a furnace should be replaced. It’s important to keep track of the health of furnace as it ages. Otherwise, your first thought of replacement might occur in the height of the winter because it simply won’t turn on or work anymore.

The average lifespan of furnace is 16 to 20 years. The first thing to find out is the age of your current furnace. If you recently moved into the home and are unsure about the furnace’s age, you will be able to find this information in the owner’s manual or by calling the HVAC company that has been servicing the unit over the years. BEWARE if no HVAC company been servicing the existing furnace at least once a year for a maintenance! This is a major red flag. In fact, not doing a yearly maintenance can dramatically reduce the lifespan of the furnace. If your furnace is between 16-20 years or between 12-15 years and hasn’t been well maintenance, consider replacement. Today’s highly efficient furnaces can last between 20-30 years.

Cost of Repair

Is your current furnace needing frequent repairs and/or one large expensive repair? The golden rule for furnace replacement is called the 50% Rule. You should replace your furnace if the cost to repair it is 50% of the cost of replacing it with a new furnace. If you have your local HVAC company on speed dial because of frequent furnace breakdowns and have a repair that will cost 50% or more of the cost of a new furnace, it is recommended that you look into replacement options.

Energy Efficiency

Are you utility bills getting noticeably higher? It could be more cost effective to replace rather than pay for higher utility bills, especially with monthly financing options. Over time your furnace does lose efficiency, especially if not properly maintained. Make sure to change your air filter every 1-6 months depending on your filter type and to always schedule an annual maintenance. Installing a new furnace will greatly improve the efficiency of your system. According to Energy Star, a new furnace with their certified logo can be up to 15% more efficient than traditional furnaces.

Other Questions to Ask Yourself

Though furnace age, cost of repair and energy efficiency are the main factors in deciding whether to replace your furnace, there are other furnace aspects to consider. If you answer yes to any of these questions, it may be time to look into furnace replacement:

  • Do you have unevenly heated rooms?
  • Is your furnace making very loud noises?
  • Do you see rust developing on your furnace?
  • Are they any cracks on your furnace?
  • Is your home developing issues with humidity?
