Best Heat Exchanger in Houston TX

On time arrival was just the start. It was obvious the serviceman was knowledgeable and got right to it. He contacted the tankless water heater manufacturer and had a lengthy discussion, including a video chat with them about the unit. The system had some significant leaking due to age and lack of service by the previous owner. They arranged for parts to be delivered in a few days under warranty.Very pleased so far and expect the final repairs next week will go well. Reasonably priced, great rapport with manufacturer, timely and efficient. Highly recommended.Follow-up - Final repair now completed. Additional parts were required but all us in good working order now. Dan was great.Glitch in a ten year old unit required callback. However the additional cost was for the part only. I appreciated the conservative approach to the repair rather than replacing every possible part. Still very satisfied with the work by Dan and the Hot Water Guys. Highly recommended.

Matthew was very professional and made sure the hot water heater was installed properly.

Techs Mica and Chris were punctual, professional, and very knowledgeable. We have been using Air Tech for several years and have always been very satisfied with their services.
