They installed central air a couple of years ago. A few months in, the attic unit started leaking through the ceiling, lights, and ceiling fans. They came out, claimed it wasn&#39;t their fault, and we spent a couple thousand dollars for the fix. I said I was done with them, but Damon seemed...

In May, I woke up one morning to the sound of a waterfall in my son's bedroom. Luckily, both he and my wife were at her parents' house visiting a sick family member. Unfortunately, that meant the water had been pouring out of the now-soggy ceiling for possibly hours, since no one was there to...

"The work was clean and the owner as well as, all of the employees were professional and friendly. The only criticism would be the failure to clean up the job site. They did haul most of the rubbish away but the employees left chunks of drywall mud and screws on the floor of the garage, empty bottles in the yard, and leftover materials, fiberglass insulation, were thrown carelessly on top of my personal belongings. Despite the messiness, I would hire this company again. ?"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."
