When to Replace Your Heating System

Furnaces that are more than 10 years old won’t run as efficiently as they used to. In fact, did you know an old furnace may be wasting up to 40 cents for every dollar you spend to heat your home? Below are a few more signs you’re due for a furnace replacement:

  • Constant need for repairs
  • Skyrocketing energy bills—without changing the thermostat
  • Hot and cold spots in different rooms
  • Furnace short cycles or spits out cold air
  • Loud rattling, popping, humming, screeching or squealing noises
  • Burner flames are yellow, not blue—this is a sign of incomplete combustion, meaning the furnace may be leaking gas and/or carbon monoxide
An older furnace may be wasting up to 40 cents for each dollar you spend to heat your residence.

Frequently Asked Questions

  • Most companies will recommend furnace replacement if the cost to repair your system is more than half the cost of a new system. At times, a repair won’t restore the heating system to a minimally effective level. The life span for most furnaces is 15-20 years, and so replacement is generally recommended during that time frame. For more considerations, visit our blog covering more details on when to repair or replace your furnace.

  • It’s often less expensive to replace your air conditioner and furnace at the same time. Plus, you’ll also enjoy greater energy efficiency year-round. Here’s when you should replace both systems at the same time:

    • Your furnace and air conditioner are more than 15 years old.
    • You want to install a high-efficiency air conditioner soon, which possibly might not be compatible with an older model.
    • You want to boost your energy savings with a smart thermostat, which often don’t work with older heating and cooling equipment.
    • Installation is difficult.
    • You don’t want to have to worry about heating and cooling repairs in the next few years.
