"I installed a new Carrier HVAC system before this summer and have been very pleased with this company. From sales to installation to service, everyone in this company has been wonderful! Glenn gave me excellent pricing and the installation, by Jorge, Simon and Aaron was performed efficiently and neatly with excellent workmanship. Robbin quickly filed the appropriate rebate and warranty forms and when an error code subsequently exhibited, Craig promptly addressed my concern. I strongly recommend this company both for its excellent pricing and all around service. It is truly a pleasure to know that there are still great companies that focus on quality, service and customer satisfaction!"

"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."

"Blake M. was able to work thru issues created by installation in a double wide vs. a stick built house. Service was professional and pleasant. Blake kept me informed every step of the way toward project completion. Area was left spotless."

"The installer was very efficient and when finished, he explained everything. Very pleased!"

"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."

"John went above and beyond to deliver a great job. We are extremely happy with the job he did changing the wiring and installing an appliance. I would highly recommend him."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"
