"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."

"I had them replace my entire HVAC system (furnance + AC). They did a great job through the whole process. Out of four quotes I received, they were the only ones that took the time to do a full heating and cooling load calculation for my house when they came to do an estimate in addition to making detailed measurements of our utility room to make sure anything they installed would fit. They gave me three proposals ranging from low-end, mid-range, and high end options and explained the equipment in each of them in detail, including documenting all the model numbers, efficiency ratings, and specs. What they recommended matched up with my research I did prior to receiving estimates. They were very responsive, knowledgeable, and professional so I gave them the job. The crew arrived on time, worked hard the whole day, were respectful of my house, and did not require supervision (although, they told me I was more than welcome to ask questions and watch anything they were doing). They cleaned up, explained the warranty and rebate options with all the paperwork already filled out so that all I had to do was sign--they even mailed both the warranty and rebate off for me. The whole process went great. While their prices were fair they were not the cheapest, but I have no doubt they did a great job, didn't cut corners, and will stand by their work if I experience any problems. They are a reasonably sized HVAC business and not a one-man-band shop like many places in the area, so I know they will likely still be around through the life of the warranty and are well staffed to respond to emergencies, including a 24/7 emergency service number. Overall, we're very happy with the new system and it's a huge improvement over what it replaced--both the AC and furnace are much quieter than the old units, more energy efficient, and perform better. It's been a month since the install and everything has been working fine without problems."

"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 />"

"Absolutely painless from start to finish. They gave us the best price that no one else in the area could match and were professional and efficient on installation day. I’m a Realtor and refer them to all of my clients and friends. Outstanding service!"

"UPDATE: it just takes 1 person to sour the pot. I do not recommend Beltway for large jobs. I found an issue after job was done and, inexplicably, someone who could not fix the issue was sent out. Even worse, they returned the next day and STILL didn't do what they were supposed to do, even after agreeing with me via text about what needed to be done. I am so angry and dissappointed. However, what I stated below is still true. ORIGINAL: The install went smoothly, the team was professional and did a fantastic job of keeping my house clean - which is incredibly hard when working with plaster. The estimate to complete the job was 3 days and it was done in 3 days."

"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"

"Sam and Chad did a wonderful job clearing the tub drain, installing new faucets in the bathrooms, installing a new shower head, and other projects. They double checked their work and answered any questions I had. While they need to come back next week to do a small part of the whole project, they were honest about what piece of equipment they thought would work, but would not. They were efficient, professional, and pleasant to be around. They made my day."
