Very good service. We had several items to attend to that had been deferred during pandemic. I appreciated that Jason, the technician who did our work, let me know what we needed to complete the job so that I could run out to purchase those items while he completed some of the other tasks. That way we got it all done on one service call.

Brendan got my hydronics system up and running!!!!! We'd been without any heat for all of January (brrrr) because all the other hydronics companies had been too busy, tried to massively overcharge, or flaked. These guys are the only local hydronics shop I trust. I only wish I'd known about them already!

We worked with Brendan at Marin Mechanical. Brendan was great and he saved us!!! He was honest, fair and professional. He walked me and my wife through each step and was always open and transparent about every thing he was doing. He explained the issue and the problem that needed to be solved. He answered all of our questions and always gave us a few alternatives and provide a recommendation.

It is so hard to find honest contractors. Brendan is someone you can trust and we will definitely use him for all of our needs. We reached out to several plumbers and contractors before we found Brendan and sadly was likely cheated. Our problem was rather complicated and others took advantage of that. We so wish we had found Brendan earlier on.

Working with Brendan at Marin Mechanical, you will receive great service and great work at a fair price, and feel assured at the end of the job, the work was done properly. I can't recommend him enough!

These guys did a small job for me and did it well. It was very pricey, however. Then they came out to check something else out and charged way too much for an estimate. It's too bad because the first work was good. They need to relax a bit and realize that giving estimates is not where they are going to make their fortunes.

I can whole heartedly recommend and endorse the work and people at Marin Mechanical. Brandon and his crew as super professional, responsive and genuinely care about providing a great service and quality heating system. I had the misfortune of working with another company that is the polar opposite of Marin Mechanical--I assure you having a competent, qualified, personable and infinitely skilled plumbing crew that know the ins and outs of not only their radiant systems, but have enough knowledge to tease apart the slipshod work of others makes a world of difference. I called Marin in to install a few new loops in our radiant system and move some things around. They discovered that the original installation was flawed, the system not properly sealed so that corrosion was happening and parts were failing, they took them off and showed me the build up. They came out multiple times as these parts failed following the significant rough plumbing, always congenial, always responsive, and tuned the system so that now our house is nice and toasty where as before our bedroom radiant wall units barely could heat the space. If you're considering radiant or you've fallen prey to other less competent companies and are looking for someone to take over and fix their mess, call these guys, you'll be glad you did.

These guys know their boilers! I have radiant floor heat in Clayton that was installed by ""Nameless Worthless HVAC Company"" in Dublin eight years ago.

They installed it wrong. I don't know @#$% about boilers...

It was then serviced by another ""Worthless BIG HVAC company"" in Berkeley for the next 8 years. They would come out, replace some parts, charge me a bunch of money and it would work - sort of. The boiler worked, but would heat the house in random locations while other parts of the house would never get over 60 degrees. It also burned a LOAD of propane. They never noticed it was installed WRONG. I just figured that's what it cost. WRONG again.

I decided to find someone who was recommended by the boiler factory.

Brenden came all the way out to Clayton and immediately informed me it was installed WRONG. I have no idea why ""Worthless BIG HVAC company"" never noticed this install failure for 8 years - Oh but they kept charging me to replace parts that didn't need replacing.

My home now heats evenly and stays at a comfortable 71 degrees in the entire house and is just sipping my $2.45 a gallon propane.

Best money I ever spent.

If you have a boiler for heating your home - CALL THESE GUYS.

We had some real problems with the amount of hot water dispersed throughout our recently build house and found our tankless system was too small. Some companies handle the heating but often blamed some issues on the plumbing and suggested I call a plumber - then the plumber suggested I call a heating company when they couldn't solve the issue. Very frustrating and expensive process without results. Jason from Marin Mechanical said they could handle everything and he built-out a new tankless system that really looks like a masterpiece when compared to our previous system. It works great and Jason was very attentive to following up quickly to make adjustments in our system as we broke it in. I would always recommend him to anyone who wants to work with someone who really knows his trade.

Marin Mechanical was great! Jason Banks, their technician, was kind and completely competent and didn't try to sell me any extra products.
Wonderful Experience and my boiler works now.! YAY!

Let me start by saying that working with Marin Mechanical was a has been great.

I am wrapping up a project in San Francisco that involved a full renovation of an existing home, and the addition of a 2 bedroom 2.5 bath second unit. The project has taken a little over a year, and during that time Marin Mechanical has been absolutely rock solid from start to finish.

The scope of work for the projects was the installation of two separate radiant heat systems (each containing three heating zones spread through three levels), and two separate boilers for residential hot water.

From the beginning of the estimate process, Brendan and his team could not have been more accessible and professional. The estimate was detailed and accurate, and they were happy to answer all of my question promptly. Over the course of the project if there were any changes to scope of work it was brought to my attention immediately, so there were no surprises in regard to payments.

From the time they laid out the lines prior to the pouring of the concrete slab, to the final install of the thermostats. Marin mechanical always showed up when they said that they would, and we're a great team to have on the job site. They worked well with my schedule, and with the schedule of my other subs.

The quality of their work is outstanding. They went above and beyond to make sure that the lines they pulled, and the pipes they laid, were as clean and well thought as possible. The system has worked flawlessly from the moment they turned it on.

I can not recommend Marin Mechanical highly enough. They are great at what they do, great to have on the job site, and are dedicated to delivering the highest quality work. Hire them and you will not regret it.

We were referred to Marin Mechanical by a radiant heat specialist in San Francisco who was retiring. We made the decision to go with radiant heat because our house is 1,000 sq. ft. and we were expanding to 1,500 sq. ft. but space was still at a premium and we didn't want to take up limited wall or floor space with air ducts, or an air return, or take up space in the garage with a gas furnace and a water heater. We chose a combi-steam boiler to address both needs. It's a small unit that fit on the wall in our garage. It was the right choice and worth the extra money. Brendan at Marin Mechanical was very professional and always available to address our concerns - even while on vacation. We had an unusual malfunction with our Lochnivar unit and Brendan took care of it immediately and got us a brand new unit. He has been great with follow through and we expect them to be around for many years to service the unit. I would highly recommend radiant heat for San Francisco and Marin Mechanical to do the installation and yearly upkeep.
