Testimonials

WHAT CLIENTS SAY

TCY Mechanical
John was professional from the moment I met him. He came to my house in a mask and took off his shoes which he didn’t have to. We agreed on a reasonable price. We scheduled for a week later, he showed up on time and was very clean about doing his work. He took his time and made sure everything was done and working prior to leaving. I had a great experience with this company and would recommend them to everyone!

Great business at a affordable price, finished my AC in less then 2 days. John was very professional and clean with his work. I had him set up a new water heater before he set up my ac and he did a outstanding job with that. Definitely the guy you want to work on your house. His affordability also beats anyone out there so if your on a budget he’ll find a way to get you situated.

Amazing work. John is very knowledgeable, courteous and professional. The installation was done ahead of schedule. He and his crew was very clean and fast. I couldn’t have asked for more. I would definitely recommend him to anyone looking to get an ac work.
