Get matched with top tankless water heater installers in Walkersville, MD

"The contractor did a quick but thorough job repairing each electrical outlet and provided advice on how to maintain them properly. The ring doorbell installation was quick and neat. The contractor wore a face mask at all times and we had a completely contact-less visit (including the bill payment - we were able to "sign" via our own devices). This company was a pleasure to work with."

"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."

"Markool was super professional, kind, and skillful. A few things really stood out. 1) He did a furnace flue piper install that he could have charged us much more for if he had wanted to take advantage of us - but he was honest and we paid less than we feared. He also went the extra mile helping my wife and I through a warranty claim with the furnace company so that we did not have to pay extra part costs. It was an unexpected need, but he was prepared with the part and worked with the manufacturer to get us covered. He was even able to better a previous repair. 2) On a home humidifier install, he made himself available on short notice, took time to answer our questions, and then showed us how to maintain the equipment ourselves so we wouldn't need to shelve out more for additional contracting work - even from him. Grateful!"

"Wow what the best experience I have had with a plumbing company ever. I needed some work done to my well and pump so I called redline. They responded within a quickly manner and were professional. I was there when they came to look at it and when they had to come to the work they came back and were very respectful and hard workers. Everything was done in a timely manner and trustworthy employees. I had to leave and left with them there and I felt that they were good and people I could trust in my house. I can’t thank you all enough. I’m very happy with the work and I appreciate it. I will call again when I need something done. If you need anything done plumbing these are your people to call!! Amazing thank you!!"
