McMahon Plumbing & Heating

Horrible customer service experience. In the midst of the record temperatures I had a couple of pipes burst. In a panic I called a bunch of plumbers including McMahon because of their amazing reviews. They told me they were all booked up for the day (Sunday) but could schedule an appointment for Wednesday. I decided to take it.
Luckily, I was able to have a different company come to repair the pipe. Shortly thereafter I realized my heat via my boiler was not working properly. I had not cancelled the appointment with McMahon for Wednesday, but they did not show up. When I called to inquire why no tech showed up they told me they had no record of my appointment, but they would call me the following day.
On Thursday, I received a voicemail and called back to get a window. They let me know my window was between 12-4, but would likely be after 2. A little after 3 I hadn't heard anything so I called to confirm they were still coming. The woman told me they would not be coming and denied the appointment. She even went to listen to the recording of my call that morning and then just apologized that they agreed to a time slot.
I completely understand things are incredibly busy, but I have twice now cancelled/rearranged my plans to be home during my set window to have someone no show. They should not be committing to time slots or making appointments and then no showing. At a minimum they should be making courtesy calls as soon as possible when they know they cannot make it instead of me needing to continually chase them. I would not recommend them to anyone as clearly their scheduling system (or lack there of) is a mess.

McMahon provided excellent service. Everyone is professional and polite. They came quickly and did a fine job. BUT ... the cost was shocking. They charged me around $900 for something that took less than a bit more than an hour, and required a few common and inexpensive parts. They don't break down how much of the bill is parts and how much is labor so it's difficult to discuss it with them. I do know they have flat fee that they charge per visit (something like $160)... in addition any charges for parts and labor. They came to my house twice because they lacked a part on the first visit and charged me this fee twice. So that's $300 before they even start charging for labor or parts. Even at $600 it would be expensive considering that it was a small and fast repair. Despite the high quality of their work and their customer service I won't use them again.

My experience with this company was amazing. Having had unresolved issues with my HVAC it was wonderful to have a professional technician evaluate, service and have my system up and running perfectly within hours. I highly recommend McMahon Plumbing. The technician was knowledgeable, polite and meticulous.

We discovered early on a Sunday morning that our water heater had failed. We were frantic. By Sunday afternoon, the wonderful folks from McMahon were in our basement, discussing options for replacement that could be done that day or the next. We chose the tankless system and McMahon said we’d have hot water again by 3:30 the next afternoon. And we did! The old broken tank was gone and the hot water was working again at 3pm — a half hour early!
This is a great company. They show up when they say they will, they know their stuff, and they are kind and helpful in stressful situations such as flooded basements. Give them a call when you need a plumber. You’ll be glad you did.
Here’s a photo of our beautiful new tankless water heater. 😊

I worked with McMahon Plumbing & Heating on a kitchen renovation, including replacing a sink and garbage disposal, relocating a gas range, installing a water fill line for fridge, installing a radiator, and relocating a hose spigot. They also replaced some corroded pipe that was uncovered during demo. Their pricing was fair and upfront, and they were prompt, professional and friendly. I look forward to working with them again whenever we need a plumber, and recommend them very highly.

I hired McMahon when the 1/4 hp motor on my hot air furnace died. It was an old furnace and the tech told me they could not find a replacement motor anywhere (they looked for couple hours) he told me a new furnace is ~$8-9k.

The tech said if I found a motor they would install it, very nice. I found one on ebay (exact model # motor but also ~30 years old). I had the tech install the old $89 ebay motor and it did not work. I understand it was my gamble and it cost me. It was ~800 for McMahon to install the faulty motor

I took the old motor to an HVAC supply (Custom Fan in Medford) and within 1 minute the guy behind the counter found an identically spec'd motor (for $280). I highly recommend anyone in the same situation to do go to Custom Fan.

I also had McMahon service the two functional furnaces (it is a triple decker) at a cost of 369/per furnace. When I looked I realized they had not even replace the air filters, and when I looked in the track the filter goes I could see the accumulated dirt in the duct work.

I paid McMahon by credit card over the phone, as I was not present when the work was done. Despite being told by the tech I would get a receipt that afternoon, and despite the fact I have called and asked for receipts 4 times I have yet to receives in excess of $1,500 dollars.

I took the new motor I found at Custom Fan and installed it myself. It works perfectly and took me ~ 45 minutes to do, would have been quicker but I also installed 3 new filters ($45).

Was a repeat customer of McMahon - not anymore. Had a service tech out to the house to evaluate a backup and diagnose. As to the Service tech and his plumbing skills, he was great. Unfortunately, the Service Tech did not have the equipment to complete the job in his truck. He asked if I needed it done today - I did not. They sent me the estimate after the visit - but are charging a "Dispatch Fee" to come back out and do the work in addition to the dispatch fee they charged today to do the work. Called customer service and got "Jennifer" who asked "What can I do to make you smile today"? I asked her about the Dispatch Fee and why they would charge me to come back out when they didn't have the equipment. She didn't care that the tech didn't have the ability to do the work today "We always charge a dispatch fee if the work isn't done in the same visit". Would have been nice if they told me that upfront. She also claimed if I had put down a deposit they would have gotten the equipment to me today or waived the fee. Would have been nice if anyone told me that. Since the tech had just left, I told her it would be great if they could get someone out to do the work today so I don't have to pay another dispatch fee. Jennifer refused. Anyway, Jennifer did not make me smile and the nickel and diming practices of this place is why I will no longer be a repeat customer. No issue with their plumbing - but I am not going to pay an extra $150 because the tech didn't have the equipment on his truck. And Jennifer could use some customer service training.

Quick and excellent capable service (by John). McMahon has provided me with excellent service for over thirty years. My go to for plumbing, heating, kitchen, bath, etc. No Question. A-One.

Poor service all around, would recommend steering clear unless you want to play guess and check with repairs. When working on my heating system the first repair was 2000$, and less than a month later the system was broken again. The second repair was quoted at 1500$. Instead of wasting 1500$ with this company I went with another heating company and the fix cost 300$. I have not had any issues since. Hoping to help someone else avoid the same mistake I made.

I recently worked with Adam, Mike, and the McMahon team to replace a previously installed indirect water boiler and tank system in my house that had shut down. Overall I'm extremely happy with the project. The installation took place the day after the initial inspection, and the team worked expeditiously and efficiently. They left the place as clean and dry as they found it, and the pricing was better than all of their competitors for the same system. I would recommend McMahon to anyone looking for a hot water heater replacement
