If your furnace is older than 15 years, it may be time for a replacement.

Gas forced air furnaces

Picture
Is your furnace or boiler older than 15 years of age?  If it is, it most likely is not a high efficiency heating unit, it also could be costing you to heat your home. If your furnace was installed prior to 1992 you may have a unit that has a pilot light.  If that is the case the efficiency of that unit is 65% AFUE or less.  
  • Is your heating unit a old coal burner that was switched over to oil or gas?
  • Is your existing unit without vent dampers or does not have an induced draft fan?       
 If you said yes, or you are experiencing  high utility bills or discomfort in your home, we recommend you give us a call to come for a free estimate.  We will provide a recommendation on your most cost effective option that suits your needs.  Call 920-469-3500 today to schedule an appointment or get your free forced air heating system quote from the Green Bay heating service experts at K.
