What Our Clients Say
  • Knauer Plumbing, Heating & Cooling has provided maintenance and installation service to us since 2002. An air conditioning system installed in 1986 continues to function, thanks to annual maintenance service. They installed a new furnace in 2002 and continue annual maintenance service. We couldn’t be more pleased with Knauer’s customer focus, accommodation, recommendations and service.

  • My husband and I have called upon Knauer Plumbing, Heating and Air Conditioning for over 25 years of professional, reliable service. They helped us find the right furnace for our home when it finally needed replacing, and their technicians kept our older air conditioner happily running. Plumbing problems and updates in a 92 year old home are no match for the expertise of the Knauer plumbers, either.
