I have been doing business with Charles at modern air of Katy for several years now and have never been disappointed. I've had to call him late in the evening for a problem and he was here within 30 minutes no questions asked. Excellent company to do business with and Charles is an amazing technician.Posted on Google Sam RossmannTrustindex verifies that the original source of the review is Google. Charles was amazing. We noticed that our AC stopped cooling around 10:30 PM. After a dozen phone calls to other so called 24/7 HVAC contractors, Charles answered and was at our house in an hour. He diagnosed the issue immediately and put a plan in place to replace the broken part. He got our unit back online the next day. I definitely will recommend Charles and his team repair and service.Posted on Google David CostaTrustindex verifies that the original source of the review is Google.

Had a problem with my AC where it would only blow out hot air. Ot was Sunday, so I made an appointment for Monday afternoon online with Modern Air of Katie. Monday morning came around and a morning meeting I had was canceled. I called Modern Air and they were about to move up my appointment right away. Charles showed up on time and he diagnosed the problem, gave me a quote, and then replaced a part it in about 15 minutes. Very quick and at a reasonable price. I was very happy with their service and would definitely use them again.
