"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."

"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."

"Everything went great. The old hot water heater was removed and then the new hot water heater was installed where I requested it to be with all of the plumbing done in a neat professional manner. It was a pleasure working with Bamford plumbing and I have been very happy with the work they have done. I would highly recommend them to anyone. <br />"

"Timely, professional, and personable technician. Provided options for repairs and coordinated an assessment for replacement of system. I’m a customer that was moved with the sale of A-One to John C Flood and I am happy with the transition. The work was on my HVAC system, but that was not listed in the drop down."

"Adam was so helpful explaining how the ductless heater/ac unit would fit in my sunroom. His three workers were great. Cleaned up the area after they finished, the job was done in about 4 hours. Got three estimates and Weather Masters was the lowest and could install the next day. I also decided to sign a contract for seasonal checkups on my furnace and central air conditioner. I think anyone would feel comfortable hiring them."

"Our furnace finally bit the dust after 25 years of faithful service. I had TriState do several small repairs and maintenance on it over the years, and they always did a good job. So, when the last service rep told me it was finally beyond repair, we consulted with Comfort Specialist, Darren, who isn't just a salesman, but previously installed and repaired HVAC systems. He took lots of measurements, inspected the old unit and the runs to the outside and upstairs. He took his time making calculations and offered us several options on a new system. TriState uses Daikin furnaces, which are rated in the top 5 furnaces for dependability and efficiency. The price, I thought, compared to my two other neighbors, who also recently purchased new systems, was even lower than I thought it going to be. In fact, my neighbors paid more (by thousands) and have a smaller square footage footprint than my house. We've had the unit now for over a month, and so far, it's great. It is a one-zone system, yet the upstairs will only vary by one or two degrees. This is much better than the old unit. We're hoping this small variance in temperature will also apply when the AC is on in the summer. The installers were very professional, arrived on time and completed the work in a timely manner. I would definitely use TriState again, and will rely on them whenever I need service."
