Harry Clark Plumbing and Heating Inc

Too bad I can't give six stars...they are that good. On Mon AM the Harry Clark dispatcher called me in response to my Saturday plea for help via their website. It was a weekend then; so they were closed. But they contacted me first thing that Mon.

At 1215 that same Monday, a Harry Clark rep knocked on my door and went off to find out why my hot water heater was no longer heating my water. Took him, maybe, five minutes to find that the computer that controls the heater was malfunctioning ...sending all sorts of error data.

The heater needed replacing. I opted to replace it with the same type I already had, but upgraded. I also opted to replace the 24/7 recycle pump with one that would be on only from 7AM to 9PM. That reduced the amount of gas burned during the low usage hours.

About two hours later, four Harry Clark trucks and a team of plumbers were removing the old heater and installing the new one and its recycle pump. In about four hours the new hot water heater and pump were up and running. In sum, from when I got the first call that AM until the Harry Clark crew packed up and left me with a heater replacement was about eight hours.

In addition to being extraordinarily fast and efficient, they were always communicating with me. Kevin, the job foreman, constantly kept me apprised of what they were doing and what came next. These guys are good...highly recommend them.

NOTE: they don't do weekends; so they're not good for emergency repairs over the weekends.

Harry Clark did a major install in my 1928 house in Oakland, which had no existing central heating and so required not only a new electric heat pump unit on the roof and an air handler and humidifier in the basement but new ducting to and registers in nearly every room. Their work was excellent and the price reasonable and they were resourceful in overcoming hurdles presented by the building and responsive to any troubleshooting needed during and afterward. I highly recommend them.

Don Marshall came to evaluate a necessary repair for our furnace within a few days of my call to the Harry Clark office. He recommended replacing some of our old furnace duct instead of simply taping the duct joints as another company had recommended. His price was similar to the less extensive bid & included new installation. We accepted his bid & the work was scheduled shortly afterward. Two guys finished the replacement in a day & left the area very clean. We noticed better heating immediately. We were very impressed with all of our interactions with this company & will use them for all of our future heating & cooling upgrades. A excellent experience!

I am a General Contractor in the East Bay and I have worked with Harry Clark Plumbing and Heating, Inc. for over 15 years now and I always work with them for all my HVAC needs on projects. I highly recommend them for HVAC and plumbing as they are wonderful to work with, professional, communicative, and they always come in on budget.

So far this year, Harry Clark installed a new HVAC system for us as our old one was really old. They were great - on time, clean and efficient. Improved the arrangement to even the air distribution to make it work better for our house. They also came immediately when our water heater died just now to replace it. Another great job! We have used them for many years and have always been pleased with the people, the service and the reliable installations.

I had my first appointment scheduled to have both heating units serviced for my duplex. All went very well and I will plan on having a Harry Clark technician back again next fall. I would not hesitate recommending them.

Worked with Harry Clark Plumbing and Heating for many, many years. They have always provided excellent service. Their willingness to work with tight real estate schedules has been extremely helpful. Their inspectors are knowledgeable, are willing to explain their findings in details, and issue required reports in a timely manner (thank you Jason and crew). The office staff, especially Daniele, will always go the extra mile and return calls promptly. Their prices are very fair for the excellent work they perform.
I can highly recommend them.

Harry Clark was very professional and on time. The moment the technician, Ronnie, arrived I knew my heater problem was going to get taken care of. He explained everything he was doing as he did it. He worked very efficiently too and got done quickly! It's always a concern that people might work slow on purpose to get paid more, but he came in and did everything so fast! I would highly recommend this company! Even the call center was a pleasure. They were very friendly and reassuring that they could handle the job. It put my mind at ease that I would have heat very soon, especially since I have two small children! I will definitely be calling them again if I ever need help again.

Excellent service. Designed and installed a mini split air conditioning system. Good planning and excellent installation by an experienced team that was a pleasure to work with. Highly recommended! Thank you, Harry Clark team!!

This review is long overdue-- for a number of years I have used Harry Clark for any plumbing or heating problem in my home or four plex. They communicate clearly, arrive when promised, work with my or tenant's schedules, fix the problem and give information about cause and prevention. Their pricing is fair and reasonable. The phones are always answered during business hours. After using different plumbers from time to time, it's come down to this one company I can depend on. If you are looking for one company to handle plumbing and heating issues, I recommend Harry Clark.

They added an air conditioning unit to our 10+ year old heating system. The crew arrived at the day and time agreed and completed the work except for minor follow up in two days. Everything works fine. In addition, they gave us helpful information about how to operate the AC unit efficiently. Worksite was completely cleaned up each day.

We had Harry Clark Plumbing and Heating install a mini-split heat pump in our home and the experience could not have been better. The installers - Matt and Martine - showed up on time, worked quietly and efficiently and cleaned up completely before they left. The office staff always answered the phone promptly and related my message to the right person, who also responded promptly. The estimator gave us a good price -- and there were no additional charges at the time of installation.

We had an excellent experience with Harry Clark installing a new forced air heating system in our 1907 house. This required much planning. The people from Harry Clark were well organized, professional and did a careful job of installing the system. In addition, they willingly communicated with us about the schedule and what work had to be done on a day to day basis.

What a wonderful, professional crew this is, full of integrity and experience, and with great and completely non-phony communication skills. In a world of phone menus and false promises and endless online surveys I was grateful to find Brad and Daniele and everyone at Clark. I don't need my hand held, I don't need to be agreed with; I need consistency and clarity and someone who understands the job and takes it seriously. This team did amazing work for my condo community when we needed it urgently, and was a dream to work with. I highly recommend Harry Clark Plumbing and Heating and am so pleased with their work.

I used Harry Clark for two jobs. One involved installing a new tankless water heater that involved running a new gas line, venting and some re-piping. The other project involved moving some exterior plumbing vents so that they wouldn't be too close to a newly installed operable skylight. In both projects, Harry Clark's crews did meticulous work and were extremely professional, competent and easy to work with. Both projects involved office staff to come out for consultation and estimates and the staff listened to what I was trying to accomplished and helped out by making appropriate suggestions for the scale of the work. When talking to other companies, I got the impression that I had to conform to their agenda rather than them trying work within the realities of what was going on with my project(s). In the future, I am planning on doing complete kitchen and bath remodels and Harry Clark will be my preferred plumbing sub on those projects. I should add that I am a former general contractor (now homeowner/remodeler) so I have a bit of experience in all of this. Based on my experience with Harry Clark I recently recommended them to a friend for a new furnace and re-ducting project, and they were chosen to do the work. If I had known about Harry Clark earlier, I would have had them do my heating system as well. So, to sum up, I highly recommend Harry Clark.

Harry Clarke installed my new heating system during a major home remodel. The project had many challenges, and the workiers from Harry Clark did a great job with it. They have also serviced the system every year for the past 5 years. Always professional, courteous and well informed. I couldn't ask for more!

Harry Clark upgraded sections of our waste pipes and did some minor repairs. I was impressed with the estimator, the 3 technicians, and the office admin I worked with.

They were up front about costs and project concerns. They communicated well. And they stuck to their estimate.

I will use them again in the future.

I have used Harry Clark Plumbing and Heating since buying my home 6 years ago. They have done extensive work for me and it has always been superior work. Everyone I have dealt with have been extremely helpful and accommodating.
Highly recommend!!

I had to have lateral sewer system replaced as it was shot. Everyone from office staff, workers on site, and owner was very professional, efficient, neat and friendly. While that was happening the supervisor on the job noticed a constant flow of water from the house and notified me, and Harry Clark got a plumber out right away and got that fixed too! Thank you to everyone at Harry Clark!

We've used Harry Clark for years. Their standards are excellent, and they stand by their work. They will also support you going to insurance companies or drilling utilities/the city if the repair is something they feel is covered by insurance or caused by somebody drilling in the street.
