We reached out to Michael after having zero luck with our home warranty company fixing our Baxi combi boiler when we lost our hot water. Communication with him was super easy over phone/text, and after briefly describing the problem to him and sending some photos he was able to diagnose our problem and the part needed to repair our boiler almost immediately. Customer service has been great. He gave us a thorough overview of our system and recommended maintenance that would likely be needed for the remainder of the boiler's life. He even followed up with us to ensure that our hot water continued to work after his repairs before billing us. He is definitely your best bet for quick, efficient, and expert service for heating/cooling system issues in the East Bay! read more

The plumber that was recommended by my HOA, was just stumped on how to solve my hydronic heat system issue. Matthew knew the solution right away, fixed it and also fix the low flow on my sink. I used to complain about the water pressure and extra time to get hot water, but now it's like magic. Just want to thank you for your honesty, great work ethics, and courtesy. You really fixed the issue permanently, rather than giving me quick fixes. read more

Matthew did a great job repairing our 30 year old thermal solar system which stopped working. I've never seen it run so efficiently and a lot quieter. Matthew was very responsive, coming over to analyze the issues and providing quick competitive quotes. Our system had all sorts of unusual configurations but Matthew displayed a "can do" attitude matched with deep expertise and problem-solving skills to work through them. It was reassuring to see him actually plan solutions before jumping into cutting pipes. Turned out we had pretty much a full system collapse and it was not easy to determine what was working or not. Matthew patiently worked through each part, troubleshooting and fixing until everything was running smoothly. Sometimes the system had to left running for a couple of days to see how it responded to real day/night cycles, and Matthew would return promptly and without delay to continue the work with the new information. Matthew and his assistant are super nice and respectful, easy to have around while they do the work. I highly recommend! read more

Our heater died on us almost before Thanksgiving. Upon calling Mathew, he walked me through the options to repair and showed up at my place ready to replace the heater. I have a complex one because it feeds the h heating system and also hot water. It was also in a tiny space, so all around a bit challenging. He resolved every issue, super profesional and very knowledgeable. The work was well done, fairly priced and clean. The new heater works incredible! I highly recommend them, in fact a couple of my neighbors have used him as well and were very happy with their results. Don't hesitate on calling him. read more

Excellent service. He fixed our hydronic heating system when no one else could. The only other company we found that would work on these type systems said we had to replace it. One visit from East Bay Hydronic and it was repaired for a fraction of the cost! read more

Expert, highly knowledgeable, great work ethic, stays until he is sure it's done right-- Mathew is simply the best I have ever worked with-- in plumbing/hydronics he was able to figure out what had stumped other experts about our system for years. Nice guy too! I don't tend to leave reviews but he is just that good! Peter read more

Matthew and his team were fabulous. He answered my call immediately, and indicated that he could meet on the day I requested. The team was on time and ready to go. I wanted to make sure Matthew and team were comfortable and familiar with older systems and they certainly were. I don't leave reviews but really need to write this one to help anyone looking for hydronic system help. Matthew and the team should be your first and only call. read more

Have a hydronic heater? Search no further and use East Bay Hydronics!! I live in a 2nd floor condo and for whatever reason all of the units on the second floor here were built with a hydronic heater. The first 6 HVAC businesses I reached out to all said they do not work on hydronic heaters. I finally came cross East Bay Hydronics, reached out, and Matthew quickly replied! Throughout the whole process we was very responsive, professional, and got the problem fixed very quickly. I wish I had found him sooner to save me all of that time researching and reaching out to others in the beginning. read more

Matthew came through again with our radiant floor problems. The thermostat of some 20 years age died. I tried to put in a new Honeywell wi-fi thermostat that had a third wire, but no luck. He figured out the transformer even though the notation was arcane and there was no real instructions for the old controller. The heater works great now and my wife is very HAPPY. If you have a radiant floor issue, call Matthew and you will have your problems solved. read more

Very pleased with my experience working with East Bay Hydronics - especially after the first company I contacted had to be nagged to provide an estimate and then charged me $265 for a misdiagnosis of the problem with my hydronic heating system. The other company's "repair" was going to be $1000! I appreciated that Matthew contacted me before he came out and walked me through some trouble-shooting so he could make sure he came with the right part. His total cost was $300! I wish I could find a company like this for all my household repairs. read more

Matthew is a pro. I wish I'd used him from the beginning. My plumber on an ADU project didn't have the skill needed to follow through on the radiant floor system in his contract. When he hit a wall, he called Matthew. Matthew fixed the problem in a few hours and left me with a very nicely-wired system, with everything accessible and serviceable. Fast forward a year and I needed help adding a second Nest thermostat in order to separate out heating zones. I got two visits from OnTech, "the Google Nest install team," and both were failures in separating the zones. Matthew to the rescue again - this time he just texted me a wiring diagram that I was able to follow for myself. No charge, no problem. System worked like a dream on the first try after that. Hydronic / radiant systems are complicated, so just go with the pro. This guy is a great resource for the East Bay. read more

I had urgent need to get self-installed radiant heat system hydrostatically tested for inspection as I did not have experience or equipment to do so. Called East Bay and Matthew was very responsive and was able to come out the next day (saturday) to get me sorted for inspection. He even left some equipment to ensure that I was able to re-pressurize system if necessary before inspection. Great communication, pricing and responsiveness. Would definitely recommend! read more

6 stars! Matthew went above and beyond with his help. He arrived early. He wore a mask. He communicated and educated on every part of his repair. We did not have heat for a week, and he came in, quickly found what to look at, fixed the issue, and we had heat within minutes. This alone would get him 5 stars. On top of all of this, he helped with with other random things for a spare minute that we were told would take weeks to fix. If you want trustworthy, knowledgeable, prompt, and long-lasting repairs, for water heaters, pumps, and even a dash of electric work, look no further. Couldn't recommend enough. Thank you! read more

I wanted to replace a burst radiator with underfloor heating. Matthew gave me a very reasonable estimate, and he and his team did a clean work, and fast. And best of all, no need to go through endless phone calls to the main office: he answers texts fast. read more

Matthew was terrific. Prompt, good value, professional. My house has now been brought into the 21st century. The vintage boiler he replace was from the 1950s and the new device is sleek, quiet and efficient. I am almost sorry that old unit lasted as long as it did because I am certain that the savings in fuel this winter will be significant. read more

East Bay Hydronics came to the rescue for me when my heating was out, and two apartment units without heat including an Airbnb. East Bay Hydronics personnel showed up quickly and got the problem fixed. They also replaced the digital display which the old one had been shorted out, and conveniently they had the replacement On The Truck ! When I couldn't even find one online. Their price was honest and considering the quality of the work and the integrity of the owner and personnel, I would say I got a great deal. Since then I have seen their hydronic radiant installs and there none better. read more

Matthew and Jesus are a joy to work with. I have a hydronic radiant heat system and they were able to quickly understand it and service it successfully. read more

Matthew helped solve our broken AC unit on really short notice during one of those 102+ degrees weeks in the Walnut Creek area. His expertise with our 20 year old hydronic HVAC system was invaluable. Save yourself a lot of grief and call him first! read more

Matthew is the man. We were new homeowners, and knew nothing about our overly-complicated hydronic system that included radiant heating, hot-water heating, and forced-air heating all in one big mess of a system and Matthew took the time to figure it all out. We had made the mistake of trying Supreme Plumbing because of their Yelp reviews and they charged us lots of money to replace a part that didn't need to be replaced and then told us we would have to spend thousands re-building the system, and they wouldn't be able to schedule it for over a week, while we were without heating or hot water. They're not bad people, but they wouldn't admit that they didn't understand the system or what was wrong. Matthew came over that same day, spent a few hours figuring it all out, replaced just a couple parts for a few hundred dollars, and explained to us everything and how it worked so we would know for the future. Months later I had a small problem, called Matthew and he walked me through it on the phone, fixing it without even having to come out and charge me for a site visit. He is very honest, reasonably priced, and easy to work with. Couldn't give a stronger recommendation. read more

My husband are new homeowners and ended up with a condo that has a hydronic furnace- something we had never heard about & didn't know how to take care of. Although they didn't end up having to come out to service it, Matthew was the most responsive & forthright with the questions I had, out of other companies I called. We're definitely keeping this company in mind for the future. read more

Matthew is a life saver. Not only did he listen politely and calmly on the phone as I explained my complex (to me) system and all the emergent issues. He showed up a week later as promised and within 2 hours put me at ease on a system that had caused two years of anxiety and produced no heat in half the house. After that he promptly gave me a written bid and on the promised day came and repaired the system to perfection. I was positive it couldn't be done! And not only that but he helped me to understand how to use the system going forward. I had inherited this complex solar/boiler/Baxi system and it is not simple to understand. Matthew was a true miracle in the flesh! read more

Mathew and Jesus were amazing, professional and thorough!! They finished a two day job in one day and were proficient in every way! In addition, they were really friendly, respectful and great communicators;)!! read more

My hydronic heating system was not working since Sunday, Aug 8, 2021. I first went through my home warranty company but they kept sending random service providers with no specialization in my heating system. After 10 days of painful experience without hot water, I was able to connect with Matthew and he went above and beyond to fix my hydronic heating system. He was very professional, attention in details, and kind enough to work in the best interest of his client. Our house is finally having hot water after 10 days, and all thanks to Matthew. read more

Excellent! Quickly diagnosed and fixed the issue with my radiant heating system. Fast response time, and great communication - answered all my radiant heat questions. Would recommend. read more

We bought our house recently, which came with hydronic/radiant heating. I tried to install a Nest smart thermostat to replace the original thermostat that came with the system, which didn't go well... the heat completely stopped working, even after reverting back to the old thermostat. I called the original installers whose contact info was on the hydronics module... they were based out of Napa and gave me a hefty quote, including over $200 just for the travel!? That's when I searched on Yelp and found East Bay Hydronics. Matthew was quick to respond (tip: text the number vs call), I sent the photos of my Nest wiring and he said he could take care of it. He came over the very next morning. He didn't charge for the visit, just the hourly rate to fix the problem. He's done a lot of Nest installs and was able to spot that my wiring was wrong and on top of that, the system was clogged with calcium deposits which is why it wasn't heating fast enough. He fixed both within an hour. On top of that, he looked at my tankless hot water boiler (not hot enough) and helped resolve that as well. He didn't just fix problems, he showed me how I can do it myself next time around, so I don't need to call anyone. I was especially impressed by his nifty infrared scanner that can see the coils under the concrete and tell if it's heating up. You can tell he knows his s**t and brings decades of experience with radiant heating and plumbing. And he genuinely wants to make you happy in your house and looks at things holistically vs individual billable transactions. This is why I love small business. I'm definitely going back to East Bay Hydronics when it's time for radiant system extensions to additional rooms. read more

It has been awhile since they finished the repair but I need to warn everyone to be careful with pricing, they don't have a standard pricing system and they rip people off if they think you have money. They charged more than $1000 for 3 hours of work, all they did was replacing a simple part, and the part was paid for separately, this was 4 times more expensive than the other technician, if I knew they were this over-priced I would have never let them do the repair. So be warned and talk about price before the work starts! read more

REALLY impressive team! Mathew is clearly knowledgable and has exceptional diagnostic skills with complicated hydronic systems. He was fair, transparent and did excellent work. He and his team replaced the water tank inside the boiler, the indirect tank and various valves, corrected the improperly configured installation ( now makes sense). They ran a copper 1 " line from the house to the city main, install a christie box and then replaced all of my galvanized pipes under the house with copper complete with a recirculation loop so that my hot water arrives at the faucet in 1/2 the time. They were unbelievably competent and wonderful to work with. Mathew also has a really strong network of people to call on. We had a sewer line back up because of a city problem on a Saturday and he had a guy with a camera at the house within an hour. I would hire them again in a second! read more

Mathew quickly fixed a simple, basic problem that other experts had overlooked (despite my questions about it) for over a year. He is adept at and at home with Baxi tankless combi heaters (hot water and radiant heat)--an artist, really. He is a treasure. read more

A few weeks ago, our heater had problems on a cold winter evening so we contacted East Bay Hydronics. Matthew responded via text first thing the next morning (Saturday), asked the necessary questions and requested photographs to diagnose the issue. He arrived promptly the same morning to work on the heater and was able to get it up and running within a few hours. We highly recommend Matthew's excellent work. We were very pleased with his skill, knowledge and professionalism. He took the time to explain the problems with our heater and was truly a pleasure to do business with. read more

If you have hydronic heating, Matthew is your go to guy! After researching vendors, we contacted East Bay Hydronics for an estimate appointment. Quickly received a very reasonable quote, and set an install date. Professional and expeditious installation had our new system up in running in no time. Evenbetter, we have seen a dramatic drop in our heating bill. read more

Called Matthew of East Bay Hydronics the day our hydronic system stopped working. He came over that day and diagnosed the issue immediately that our 20 year old system had reached the end of its life. He started working on it right away and replaced our system over Memorial day weekend. He is very knowledgable, a hard worker and a pleasure to do business with. He will be back annually to check and maintain our system. A true professional. Highly recommended. read more

Matthew is responsive and knowledgeable. I was so pleased to reach him on a weekend and have him come out right away when I was stuck. He has continued to work on our radiant system and improve it's effectiveness. It is wonderful to know someone who is as conscientious and professional as he is. Many thanks for the service several times over. Highly recommended! read more

The only hydronics service (and I have tried a few) I have experienced that diagnoses problems with logic and delivers. This is my "go to" service in emergency when everything else fails. read more
