REVIEWS

"Fantastic service, unlike the local guys, they went through my furnace from top to bottom, checked my lines, tank filter, cleaned and tested everything. This was my second time having them service my furnace and I will be calling them next time as well because the service was just that good. Keep in mind: Good workers are one thing, but having an upbeat and happy personality took them over the top. I highly recommend Knowles Mechanical."


Ray Lemar

"I want to share a great experience I had today with Knowles Mechanical. The staff was super from the receptionist, to the supervisor to the technician. They were all super professional with a pleasant attitude. They showed up on time as promised, did the job in a workman like manor and even showed me pictures of what they found and how they remedied my problem. Bill the tech guy was exactly what you would want in a service person, thank you Bill. I Highly recommend Knowles Mechanical."

John Carey

"Total replacement of HVAC system in the factory building. They kept us informed of their plans. Their people were thorough, polite and competent. Changes were taken in stride with minimal impact on cost and schedule."
