"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"CMK was very professional from start to finish. They showed up on time and very quickly repaired my burst pipe. I will definitely be using them again for any of my plumbing needs."

"Yes, one day install conversion from tank electric to tankless gas with water softener"

"Responded immediately and able to get my new hot water the very next day"

"In April 2026, our broken cast iron pipe needed to be replaced, but we didn’t know how extensive the repair would be. From Angi's referrals, we called Full Swing Plumbing who arranged for Nick, one of their plumbers, to come to our house that same afternoon. Full Swing waived the dispatch fee. Nick used his endoscope camera to see the extent of the problem. (They had a coupon on their site which offered this one-time, free service.) After a couple hours, they were able to identify the problem, present a few solutions, as well as a final estimate before they left that day. We agreed on the approach and set a date for the following week. Nick and his co-worker were friendly, deeply knowledgeable, and hard-working. They communicated well, taking photos for us throughout the process. They cleaned up everywhere, completed the job in one day, and they kept to their price. Everything worked well from the single visit."

"My gas water heater was leaking and starting to get a bit old... so I needed a replacement. Boston Standard gave me an estimate after emailing them a few photos of my existing setup, and came out to replace it the next morning. Their estimate came in lower than another company I looked at by a fair amount. They also gave me a discount on a scratched water heater they had on hand that another customer rejected. The were prompt, professional, and got the job done quickly. I will absolutely hire them again for my plumbing needs."

"The water heater replacement went really well but they haven’t called me when I wanted more services.  They went above and beyond to make it elevated in case my basement flooded again.  Two or three people came out."

"Prompt, knowledgeable, professional. J.R. Answered all questions I had about the tankless water heater before he replaced it. Knowing he stocks the parts for the unit is a comfort. I called through home advisor and he replied immediately, he came by house to give an estimate the next day, promised start date- (he got to start my house earlier than planned while juggling another job)-he then worked on my water heater until it was finished - I was able to have heat and hot water earlier than promised so I was very grateful."

"Our experience with All Phases Mechanical has been excellent. On the first occasion we used APM, we lost heat during a cold snap in the middle of winter. We called in the morning and a technician arrived that afternoon and quickly determined that not only was our 20 year old furnace in need of expensive repairs (which a friend of ours in the construction industry validated), but continuing to run it would potentially result in a carbon monoxide hazard to my family. Carl gave us clear options and helped us understand benefits (rebates, no interest loans, etc.) that are available from the state to assist families in our predicament. We decided to move forward with a new furnace and Carl's team installed it the next day. On the second occasion, APM helped us our central air conditioning system. Again, Carl sent a technician who arrived promptly the same day, who determined that the air conditioning system was fine but it wasn't working properly due to faulty wiring. He quickly fixed it and was on his way - all at no charge. I can't say enough about All Phases Mechanical. If you're looking for a local company that cares about its customers (and understands that heating and cooking problems need to be addressed quickly), All Phase Mechanical is the company you should use."
