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 your furnace or boiler is 15 years or older, and you are experiencing  high utility bills or discomfort in you home we recommend that you a  highly-qualified home performance or heating contractor come out to evaluate your existing system or concerns  no charge and will  provide recommendation if it will  be more cost-effective to replace or improve your homes insulation and air-tightness, repair or insulate duct work, or tune up your system.  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.
