Ledi was great working around my house. He and his crew would come early and do their job efficiently and in a very outstanding manner. I’m happy to have had Ledi servicing my house. 100%

We recently had mini splits installed in our big-ass Victorian by McMahon. Our house was always freezing in the winter and boiling in the summer. And because of the layout of our place (lots of rooms/no real open areas) we had to have so many window units that it never really cooled anything down. But that's not the case anymore. And we couldn't be happier.From the start, everyone at McMahon was just awesome to work with. Our first contact was Steven, who explained everything to us and helped us problem solve for what would be the best solution. After we decided that, Ledi did most of the installation (always with a helper). Ledi does more work in a day than I do in 3 months. He was just great (even our pets loved him). The electricians were awesome. Everyone involved was stellar. McMahon even helped us with the MassSave info we wanted to fill out for an interest-free loan that was available.I can not say enough about them. If you are looking to get any heating or cooling units installed, use them. You will not be disappointed.

Ledi and Rodney were efficient and fast. My heat pump installation was done in 3 days! No fuss no muss! They just got down to business and got the job done. And they never let my cat get out.

I needed a new boiler put in. Jack and Ron were awesome. Very professional and very knowledgeable. They took their time to make sure everything was working properly. They are very personable also. Jack also gave me advice on anything I might need further help with.I'm sorry if I got Ron's name wrong. Not sure if it is Ron or Jon. I apologize for not remembering. Thank you for all the time and work they put in. They left my cellar very clean and took away all of the old boiler.

I had a great experience with McMahon Plumbing and Heating from start to finish. Nick came out to quote a project at my commercial property and was professional, thorough, and transparent throughout the process. At my personal home, Pat came out to check a heating concern and performed a detailed inspection to ensure everything was operating properly. It turned out there was no real issue, but I appreciated how thorough and honest he was. Both were knowledgeable, courteous, and easy to work with. I highly recommend McMahon Plumbing and Heating to anyone looking for reliable, trustworthy service.

I just have my furnace replaced by Rob and Jack at McMahon Plumbing & Heating and they did a great job with the installation. They were friendly and quick to get the job done. Thanks to them, we now have heat in our home.

2026-01-10T00:47:12.023Z

Our call to McMahon for a furnace/heating issue, on one of the coldest days of the year, was the best call we could have ever made. The office staff was helpful and understanding and pointed Jack in our direction to help with our emergency. Jack was professional, knowledgeable and patient. He was able to get us heat until he and Robbie could replace our furnace. Jack and Robbie are a great team - they were friendly, responsible and conscientious and worked efficiently and neatly to replace our furnace.

We had a new shower head and bidet toilet seat installed by Patrick and JD. These men were very professional and did an excellent job, including leaving the area spotless. They explained the work they would do and checked in with me at completion to make sure everything was to my satisfaction. Grateful to this professional team for a job well done!

They were absolutely professional and excellent at their job. Ledi was my service person and he was knowledgeable and did everything perfectly. He got my part for my heater motor quickly. He was like a surgeon, only 30 mins he replaced motor and heat was was working like new!!! He made my New Year! 2026 will be a warm Winter inside my home.

2025-12-30T19:40:59.269Z

Ledi was great! Incredibly helpful!

2025-12-18T23:50:38.734Z

The technician Ledi informed me the installation of my new heat and hot water boiler for my house will take 3 days to finish during which I’ll have no heat nor hot water in the cold days of December. I accepted the reality and allowed the work to begin. The tech and his helper worked nonstop, no break even for coffee I offered, and the job was finished in 2 days instead. I now have heat and on-demand hot water for my house. This is what I call “under promise and over deliver”. Great job Ledi!!! Thank you for the clean and fast job.

Patrick and his assistant performed the annual tune up on my heat pump system, which McMahon P & H had installed in October 2024. Patrick explained what needed to be done. He also drove to a store and purchased the required air filter, replacing the existing one. The team was professional, friendly, efficient and left the area clean. I was very pleased with the service. A job well done!

2025-12-09T21:23:47.750Z

Ledi and his crew were absolutely amazing!! They were considerate and extremely professional. They arrived on time, were respectful of the property, treated the residents with respect and completed the job in a timely manner. After completing the job they explained how to operate the system and how to perform routine maintenance.

Great job getting our heating system back on track. David and Jdl were really informative, helpful, and kind. They answered all our questions and got the work done quickly.

Ledi hooked me up. Thank you McMahon.

2025-10-11T02:35:42.248Z

The technician Ledi - who came was professional, kind and courteous. I didn’t have heat, my home was cold and I had grandchild here who is susceptible to colds. A part was needed, and Ledi on a Friday evening, left, found the part and came back. Honestly I wasn’t expecting that. Thought I would have to keep us warm until tomorrow. He was quick and my home is warm now. My grandson and thanked Ledi for the awesome work. All the technicians I have had from here has been good workers and I appreciate them all.. They do good work.Thank you once again McMahon Plumbing and Heating!!

We recently had a new boiler and water heater installed by McMahon and we were very satisfied with their work. Steven gave us the quote and was very responsive to our questions. Pat and Jack got the work done within 2 1/2 days and they cleaned up everything after they finished. Special shout out to Jack who also figured out why the hot water pressure was low in our kitchen faucet. We’ve had at least 5 others plumbers look at it and no one could figure it out - until Jack. Great experience from start to finish!

My overall impression of this company and their employees is that they are professionals, excelling in knowledge, and customer service. We are overwhelmingly impressed with Steve Hardy mechanical operations Mgr. And Patrick and Jack who installed 3 gas furnaces in our home. Patrick and jack immediately put their heads down and worked so hard installing our furnaces. They are Hard working young men who's goal is to do a fabulous job and ensure that we were pleased. This company also installed a large water heater for us problem free. Thank you. We very much appreciate your work and professionalism. We highly recommend this company and their employees. Theresa and Linda

Ledi came because our heat wasn't working. He was very kind and explained the issue in detail. We need a replacement part. They plan to come back next week to finish once the part is in stock. We appreciate all of his help and look forward to continuing to work with this company.

2025-09-19T14:15:06.803Z

Ledi showed up early and finished the work quickly. Left the area clean. Very satisfied.

2025-09-18T16:18:10.607Z

I had a leaking problem and could not figure out why. I called McMahon, and they very quickly got someone to check out the situation. I already wanted to get a drain cleaning, but the leak was also an issue.Ledi was amazing help! He knew exactly where to look and what to test to find the problem. He was able to pinpoint that the leak was coming from my shower when the water rose and drained. He let me know how to avoid the leak and cleaned the drain beautifully! I am positive the leak won't be coming back :)He also put some silicone behind my sink so the water from it wouldn't keep getting into my cabinet! Very helpful!

2025-09-16T18:26:49.780Z

Ledi came by and made it look so easy 👍👍👍.

2025-09-08T21:00:36.978Z

Patrick and JDL were Great ! They were knowledgeable and very efficient. In 3 hours they found the problem, obtained a part, and installed it in the HVAC system's compressor on the roof. My A/C is working again. Both repairmen were professional, courteous, and trustworthy. I couldn't be more grateful.
