"We recently had the pleasure of hiring Dawson Mechanical to have a new Navien tankless water heater installed. This was a little more than a straightforward job since the water heater was being relocated from a utility closet to the garage which was about 20 feet away. From the time I made the first call to Dawson, I had a good feeling about this company. Dave came over within a few days on a Saturday to look the job over and give me an estimate. He is very knowledgeable and took the time to answer any questions we had. When the day came for the installation, a crew of 3 workmen arrived around 9:00 AM and did not stop until the job was finished around 5:00 PM. They did an excellent job, were very good about keeping everything clean and neat, and the workmanship was top notch. In short, we were very happy with everything and would not hesitate to use Dawson for our future plumbing/HVAC needs."

"Excellent HVAC and Solar installation services! They did a great job installing a new HVAC system for us a few years ago, so we sought their services again for Solar installation. They were very professional both times: provided pricing right away, technicians were polite, and job was completed in a thorough yet efficient manner. Jobs well done!"

"What a pleasant experience. Mark did an amazing job and price was almost too good to be true. Air ducts were cleaned throughly with very fancy equipment. He also offered us a full dryer vent service for a price of regular blow out price AND sanitized all ducts for free! I will include just one set of before and after pics company sent us after completion of work. Kudos to Mark and HomeLux!!!"
