Jay Stewart 7/8/2019

This is one impressive young man. It is seldom that I have dealt with a person in regard to any matter that was as knowledgeable as Mr. Stewart and possessed the ability to explain the whys and wherefores as well as he could. Sincerely, if I had a business, I would hire him away from AllTech Services and establish him in my business as Vice President and Chief Executive Officer. There is nothing this young man can not do. No doubt AllTech has already realized he is an extraordinary person in all regards. You should be very proud. With best regards. Bill Miller more

Review for Vinny 5/25/2019

Vinny provided excellent technical support in diagnosing our heat pump issue. He really knows heat pump systems. I'm a technical person myself, and can attest to the fact that he gave very accurate information in diagnosing and explaining the problem. Our system is back up and running efficiently. It appears to me that his company, Alltech Services, has a high number of customers and not enough highly qualified techs like Vinny, because he seemed to be overloaded with work. I hope this was only because our problem occurred the week before a holiday weekend. Vinny made time to get the job done, though, despite scheduling difficulties. We appreciate his dedication to quality work! more

Geothermal Checkup 5/23/2019

Frank Davis was courteous, knowledgeable and efficient; all characteristics I am looking for when I have my geothermal system checked. more

Excellent Customer Service - Technician Vinny D 5/22/2019

Hired Alltech to come take a look at leaking A/C unit located in basement of my home. Technician Vinny D showed up promptly, professionally, and fully prepared to fix the problem. He was extremely knowledgeable about the issue and explained everything in a way that I could understand not only the issue, but also everything he was doing. I highly recommend him and will not hesitate to request his services in the future. Great experience overall! more

Work done well 5/20/2019

Our annual HVAC maintenance was thorough. The technician identified a problem and fixed it before it became a major problem. He arrived on time and performed all tasks efficiently. He was confident, knowledgeable and professional. I would definitely recommend Alltech. more

Review for Victor 5/1/2019

Victor did an excellent job trying to locate a source of our leaking AC. We live in a condo and he went out and spent a inordinate amount of time with our condo's office manager going in a very small crawl space outside of our building trying to find the source of our leak. Nothing was found but he took that extra step. Victor did notice that the pan in our ceiling is not level so he will be back with an associate to level the pan. He will have to cut into the drywall to do this. In any event, he is excellent!!! 5 STARS. Anne and Kenna Lewis more
