"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"I got four estimates before choosing Michael Bonsby. They were the only HVAC contractor to actually measure my house and recommended a system based on those measurements, which turned out to be a smaller and more affordable unit than my existing system. The other three just assumed the existing system was properly sized and proposed replacing it."

"If you want honest, straight-forward, complete, and competitive pricing for a new HVAC system, go to Bluestar Air Mechanical. Our 21-year old systems needed replacement and we began our quotation/search process. Amongst the 7 companies we inquired with, Bluestar had the most comprehensive explanation, set of offerings, and was patient with us as we completed our comparisons. John promptly and completely answered all of my questions ranging from installation, future usage, efficiency, and advice on what was necessary vs an accessory. Lynn at the office was prompt and courteous on all of my scheduling, dispatch, and payment inquiries. You'll get top notch quality, service, and friendliness if you work with Bluestar for your HVAC replacement needs."

"The Buric team did a great job of installing two new HVAC systems in our house at a reasonable price. This is a family run business, the owners of which take pride in their work and pay attention to detai. The Buric team was also able to add zoning our systems, where other contractors had said this would not be possible. The work was completed in a timely fashion, and the team cleaned up nicely after itself. We had two babies in the house, and the team took care not to disrupt their sleep schedules."

"I am SO pleased with this experience with GAC and highly recommend them! OUTSTANDING information and research on our behalf by Kelly for estimate options and finding the best unit and price for our needs. Chris was very impressive when he came to our home for preparation of the HVAC air handler/heat pump installment. Top notch work by John and the GAC crew on the actual work putting in my unit. They gave us the option and were qualified to run/install a new wire for our electric needs to have all energy savings of the equipment. Easy scheduling with Monica and follow-up too. ALL the GAC staff were happy to answer our various questions in full detail so we understood everything in this project and could make informed decisions. GAC found a high quality unit (Bryant) that suited our needs AND qualified for a PEPCO rebate, which they quickly filed on our behalf. We have been customers for years with GAC for maintenance and with this install, plan to be for years to come."
