A G O'Brien Plumbing & Heating Co

Excellent service and very honest. I recently had A G O'Brien replace all my old 1950's era water pipes with new PEX and I couldn't be happier with the results! I have great water pressure for the first time since moving into the home and no more rust clogging my faucets. I would 10/10 recommend and will be a returning customer for future projects.

Efficient and professional technicians. We had a positive experience and would definitely recommend.

We had a pipe that burst from our upstairs bathroom and leaked into our downstairs kitchen. I called A G O'Brien at 9:30 AM. By noon they had a plumber at my house. He quickly diagnosed the problem and within 45 minutes had removed the compromised section of old pipe and replaced it with a new plastic elbow joint. A very impressive customer service experience to say the least. I would recommend A G O'Brien without hesitation.

Dan and Jeremy were here exactly when they said they would be here. They always let us know what they were doing and answered questions when we had them. Very personable and pleasant to talk to. I would recommend them to everybody

For the past few summers, our family cabin has been way too hot and uncomfortable to stay at. We didn't have any AC and it lacked proper circulation. We had AGO Brien come out to install a mini split and our indoor cooling has been a night and day difference. They were clean, efficient, professional and I'll definitely be recommending them to anyone in the area.

Called to diagnose our furnace. They showed up with an apprentice and let the apprentice look at our furnace. They diagnosed it and we decided not to fix it. Then charged us $250 for for 2 hours of labor! When I called they said that your charged for drive time from when they leave the shop as well as the time looking at the furnace and the time back to the shop. We will never use them again! Who charges for drive time to and from your house? And then charge by the hour and have an apprentice being trained on site, which takes longer than a professional who knows what they are doing? Glad we didn't fix it, who knows how long it would have taken an apprentice to fix it. Lesson learned!

AG OBrien recently installed a new toilet for me at my home. Service was prompt, professional and pricing was good. I have used this company multiple times and have always been pleased with their work. Thank you so much!

Received polite, quick, efficient and affordable service .Called other companies but the quickest to do the service we needed was by A.G. O'Brien .Servicemen kept work area neat and clean throughout job. I would highly recommend this company for HVAC.

So pleased with their service!!!! We had 2 leaking toilets at the same time. We called them on a Monday and they fit us in that same day!!!! No leaking toilets anymore!!!! The plumber that came out was great!!!!
We can’t recommend them enough.
Thank you ag O’Brien!!!!

We'd been having some plumbing issues in our storage / laundry room. We reached out to A G O'Brien over the weekend when things really started acting up and Chris was able to give a simple solution to put a band aid on issue until he could get one of his team members out to our place on a regular business day, which in the end saved us money. The following Monday we had a plumber come out to the house and fix the issue quickly and effectively. He was on time, friendly, and wore a mask to keep us safe.
