When You Should 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 every dollar you spend to heat your property.
