"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."

"Dan and Joe from Harco did a great job on a complex water heater installation that involved moving an air duct for a reasonable price. They were courteous and even took off their shoes when in my home. Unfortunately, there were a few hang ups initially with the installation but returned back and made everything right without question the same day. They also honored their initial estimate without any additional hidden costs. Thank you Dan and Joe for your hard work and valued savings for this particular job."

"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation. BGE will be meeting me on-site on Tuesday, June 9, 2026, at 9:00 AM to review and approve the proposed exterior meter location. I need a licensed plumber/gas fitter who can either attend that BGE site visit or come immediately afterward to evaluate the work required on the customer side of the gas system. The scope of work includes: - Inspecting the existing gas piping to determine whether any portion can be safely reused; - Extending, repairing, or replacing internal gas piping as needed; - Establishing the new customer-side gas connection point for the exterior BGE meter; - Pulling the required gas/plumbing permit; - Performing the required pressure test; - Coordinating the requir"

"This review should probably be three separate reviews, but I think it shows my trust in Vernon using him multiple times. He came out to give me a quote on a new gas water heater and relocating it about 8 feet over in the basement. The price was reasonable and he provided me the water heater information so I could see it's reviews beforehand. While installing my water heater, my tenant called and said the AC was not working. So, after completing the install and his other stops that day, Vernon went over later that day to take a look. The repair required a new part, so a few days later he repaired the AC and I had him replace a leaking pressure valve while he was there. About a month later, a house I renovated needed some repair work on a leaky drain before settlement (he was not the initial installer). Vernon went into that crawlspace and repaired the pipe and provided the appropriate documentation so we could get to settlement in time. I had Hamilton Plumbing and HVAC do work at my home, my rental, and then my house flip. I plan to have Vernon come back to run a gas line when I install a gas fireplace and again when I do my basement bathroom."

"Very happy with the team that installed my water system. Not only is taking a shower 10x better. But the drinking water is fantastic. Thanks Vinnie and Purefect Water Solutions. I would recommend them anytime!"

"They were very responsive, came the same day to take a look so that they could install following morning. They came right at the beginning of the time window and finished as promised after couple of hours. HOWEVER, when it came to the coupon (which reads: "AQUA PLUMBING & HEATING CO, Water Heaters – $25 off any job for Angie's List members either 10% off up to $250.00 off bill***Please mention coupon when scheduling") they did not give me the 10% off (w`hich `would have been 132.50 USD) but $25 off on 1350 USD. Upon me asking they said the coupon is "awkwardly worded" and it's the $25 off - period. If I would have known that or the person I scheduled with and mentioned the coupon to would have informed me, I would chosen another provider with a better deal."

"We needed to replace a toilet, James went with us to Home Depot to select one. We now have a water efficient and higher seated toilet, which is great for aging relatives that can’t bend so easily anymore. I would definitely hire/contract him again!"
