"Wonderfully. Jesus Hurtado is your guy. Awesome. One of the tubes was retrofitted into a existing roof/ceiling penetration where a chiminea and ducting had to be removed, and the hole enlarged; the other was new and included a solar powered night light. Very happy."

"From the start Michelle asked the right questions and from those questions came up with an estimate to not only meet our needs but made suggestions to improve our systems. No high pressuring, no badgering and only honest quotes with no hidden costs. The project manager Dannielle was on top of the project from day 1 and if needed was quickly on the phone with me if something was not going as schedule. She coordinated with all of the contractors and keep me in the loop as the solar system was being installed. I would highly recommend Rooftop Solar to anyone and have recommended them to all of my neighbors. 7 months later I contacted Michelle for some questions and she responded immediately with answer to my concerns."

"We were very pleased with the Richard and Ben's work. They were extremely professional and responded to all our questions and gave us some additional advise which regard to the vents and potential solutions which we ultimately implemented solving our leakage issues. I also visited the company's site and researched other references prior to hiring Trusted. In every case nothing but high marks were given and after our service I can see why. Trusted will be my go-to HVAC contractor from now on. Extremely professional.
