"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"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 />"

"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."

"Weather masters corporation installed a central AC unit, a complete HVAC system. The company is by far the best in the Washington metropolitan area. One of their customer relation person known as Adam Shapiro first came and assess the project and then brought two of his team members who are very experienced about Airconditioner installation. The two gentlemen were very professional , punctual and very fast. How they were able to fit in the Air handler into a narrow cubicle space surprised me. Also, their price is more reasonable compared to others. This is a company that gives you the reassurance that they will always be there if there is any problem which I am very confident there will not be any issues. I am so glad I made the decision to have them install my AC, HVAC is not the kind of project you will ask any kind of engineer or technician to install. I will recommend weather masters to anyone who needs AC installation."

"Donny and Phill arrived on time installed floor protection and shoe coverings and did an excellent job in far less time than I expected. I would recommend Tri State for installation and maintenance of HVAC systems."
