"An absolute savior and perfect professional. After getting ripped off 4 times for shoddy work by other unprofessional muppets, this company saved the day. We hadn't slept in 6 days of boiling heat and humidity because of missed appointments and broken promises from 4 other companies. Including the one that we found out later ripped us off and left us flat. KNF fixed everything. Communication , dedication to craft, follow through, were exceptional. He came back just to check on his work and honor his workmanship and denied a tip just because he wanted to make sure we were up and running and comfortable finally. He actually cared! about us hiring him and our satisfaction. Couldn't be luckier KNF ended our yr long nightmare of a broken 1yr old unit and multiple expense and frustration. KNF is a value no matter what they charge. I would never trust anyone else again. Feel absolutely welcome to message me privately if you think this review was given for any other reason than being blessed by someone recommending KNF. They even denied a job I referred them too because they felt it was not the right thing to accept because they felt it wouldn't be prudent for my family member to install what they asked for. Hire them. Value, integrity, passion for what they do, customer service and a dedication to workmanship. What more could you ever want from any contractor or purchase. "

"Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

"Service was fast. Called and they came out same day. Nice and quick to find problem. Will use again.
The only reason I'm not giving a better review is that I was told in a text a service call during the day would be $60. I was charged $90. All I needed was batteries in my thermostats. My bad for not knowing that, and my bad for not asking again before having someone come out.

"We recently hired John Macdougall to help my recently widowed mother. I tried to get 2 other companies to come and neither was responsive or fair with prices. John was not only highly skilled but was very kind and sympathetic to helping a widow of a recently deceased Veteran. John immediately knew what to do to get the AC repaired and his pricing was fair. When we called to thank John he said he always looks out for his customers especially the elderly. THIS IS HOW A GOOD BUSINESS IS OPERATED. We will always use John because he is a highly skilled, decent guy. THANKS COMFORT ZONE."
