“We've used AG O'Brien twice now, once for replacement of an outdoor faucet and once to replace our central air system. We appreciated the quick responses from our sales representative (Ty) and the plumbers who came to do the work at our home were super friendly. I'd be happy to recommend their services to friends and family.“

“Mike was fantastic - kind, courteous, answered all of our questions, explained everything. He left the area he was working in very clean. Highly recommended for any plumbing service. Both Mike and Tom have done other projects at our place. We couldn’t be happier. Thanks you“

“Great company did a nice job recharging my mini split it now running at optimal temperature control“

“They were very accommodating to my schedule, professional and quick, they were early and had the job done in half an hour.“

“Emailed them for heating zone issues with our Viessmann Combi boiler. They responded within an hour and scheduled a service visit for 2d later. Technician tried to flush heating zones but could not so advised us to heat rooms where pipes were located with space heaters. Eventually this thawed pipes and flow was restored. I would recommend this company based on this experience.“

“Corey and his crew were very personable and I was very happy with the customer service. They did a great job repairing my furcanace and I even had them install a mini-split. I would use them again, without question.“

“MMT Heating and Cooling is our go-to for all mini split and boiler issues. They installed our mini splits on short notice in spring of 2021. They were super responsive and really made us feel like our home and needs were a priority for them. We got quotes from two other companies for our AC but went with MMT because they were the most responsive and professional in their communications and gave us a lot of confidence that they'd do the job in the most cost-effective and efficient way possible. We've been very pleased with the outcome.They also replaced our boiler and a thermostat. The number one thing I appreciated about their work on our boiler (besides being nice and warm again) is that they were SUPER clean! When they were done for the day, there wasn't a trace of the enormous project they had undertaken in the basement. That was HUGE for us because we have a toddler who will find anything that she's not supposed to eat, including trash and debris, and then she'll try to eat it.These guys are phenomenal. We really appreciate and respect their work and would def recommend!Services: A/C system maintenance“

“Trevor (and his helper) from ASP were very informative of what we could do about the issue I had with a drain pipe as well as listened to my concerns about needing the repair done quickly. Trevor quickly got me a quote for the job and had it fixed before I got back home. Very professional and helpful beyond belief. I would use Trevor and ASP again for any plumbing issues!“
