Cues That You Need to Replace Your Heating System

Furnaces older than 10 years old won’t run as efficiently as they used to, and certainly not as well as a new system. An old furnace may be wasting up to 40 cents of every dollar you spend to heat your home.  There are more signs you should start thinking about a furnace replacement:

  • Constant need for repairs
  • Higher energy bills with decreased warmth
  • Varying room temperatures
  • Furnace is short cycling or producing cold air
  • Odd rattling, popping, humming, screeching, or squealing noises
  • Burner flames are yellow, not blue, meaning incomplete combustion from a gas and/or carbon monoxide leak


An old furnace may be wasting up to 40 cents of every dollar you spend to warm up your house.

Stay warm while you take it easy on your budget.
