"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!"

"Rob O'Donnell came in clutch for us when we found ourselves in a pinch doing a job out of our normal service area for a customer who had water damage to their home. It was after 4:00pm on a Friday afternoon and we needed to find someone to disconnect a gas stove so we could finish installation on Saturday. Needless to say, we were having trouble finding anyone who could help us out with such short notice. After leaving a message with O'Donnell's Plumbing we got a call shortly thereafter from Rob, who was willing to go out on Saturday morning to disconnect the gas line for us before another job he already had scheduled for the day. He also returned very promptly to get everything hooked back up. -- furthermore he was able to send an invoice by email and we were able to pay electronically! Very convenient and also eliminated the need to bother with mailing a check. -- Highly recommend O'Donnell's Plumbing!"

"Phone contact was very prompt. Service person arrived within 1 1/2 hours as promised. Problem was resolved and a new sump pump was installed. Time will tell if problem was totally solved. (need a rainy down pour to see. )"

"This plumber was referred by Home Depot. He was the third person that returned a quote. He offered the best quote. We scheduled a convenient time and he arrived on time. He fully explained the work that needed to be done in a comprehensive manner. The work was done in a timely manner and left the area clean. Payment was within the initial quote. I would hire this plumber again."

"F. H. Furr did the tasks I requested. Two tasks required the lighting be replaced."

"Honest and upfront about what really needs to get done. Another company had bid that was 10 times higher, though included a lot of water purification stuff that isn't needed."

"It went well. The install was done in approximately 3 hours; knowledgeable technicians. Our drinking water tastes amazing and resolved hard water problem."

"If you want a reliable job done safely and at a fair price, Rodney is the person to call."

"Brad was great explaining everything from the work that needed done to the heat pump units themselves. I liked that he called prior to his arrival with an ETA . Did do a free estimate with us. We decided not to go with Tristate in the end and went with a small local business instead but Brad was super friendly and helpful."
