Best Mini Split Installation in Boston MA

We had a very difficult problem and McMahon Plumbing was very responsive and figured out what was wrong and fixed it very quickly. They are very professional and they do care about the homeowner.

Great response and quick service, I had to replaced water boiler ,the company provide 3 replacement rinnai water heaters on demand, installed right away, great price ,quality job, work perfectly, I will recommend 781 plumbing to everybody.

Complete ripoff, they wanted to charge over $2000 to install vanity that was offset by 2. I had another company come for it for $400.00. Complete waste of time and money having them show up late for a quote.

I had my system installed by Sila several years ago and they did a good job. Very recently, my heating system was non-responsive late at night and I called their on-call technician, Michael. He guided me through a system restart while I went to the attic. He was very courteous, patient and encouraging, and we got the system up and running. Michael is a significant asset to the organization. Thank you!

Caesar was timely, polite, and professional during his visit. He was able to replace the broken aspect of the furnace for a very reasonable cost. Would use again.

Kevin was very quick to answer my email and phone call and was able to check our units just a few days later! He did a great job on assessing what was wrong, diagnosing the problem and repairing it. He also was great at explaining the process to me which I really appreciated. I'm so glad to FINALLY have a functioning AC again! (Particularly before summer starts). Thanks again Next Step!

We needed help with our HVAC system during a heatwave. They were very quick to respond and very helpful and they came out. Would recommend to anyone.

Great experience working with this company. I have had two water heaters go bad and their emergency service was prompt, neat and professional. Would recommend them to anyone in or around the Quincy Ma area.

Kladji and his assistants, Chris and Declan, did a first-rate job of direct venting an existing furnace, installing a toilet, and repairing a risky pipe leak - all in one ten-hour day. Throughout the job, I kept asking for this and that option. Where they could accommodate my requests, they did. Where they couldn't - whether because of code or plumbing common sense - they explained kindly and thoroughly, never seeming impatient in the least. I'm extremely satisfied with their work and look forward to having Kladji back whenever the house needs something else.

Finally !
A plumber who returns your call, provides a competitive estimate, completes the job as expected and cleans up afterwards.
Mound Mechanical provides professional plumbing services !

We needed a new furnace and water heater when our Navien Combi system failed. We didn't have hot water or heat, and few were returning our calls. Those that did call back gave outrageous estimates.
Everyone, except Mound Mechanical.

They replaced the unit as described, and we quickly had our warm home and hot showers back. We are thrilled !

Great people , answered in the middle of the night! Had a pipe leak , took care of it ASAP. Professional work !

Service person came on time, worked efficiently, and solved my problem.
