Reducing our carbon footprint. Harry Clark installed 9 KW solar system on its office building in 2010.The panels cover most of the roof. All of the lighting has been upgraded to LED type. We have modified our fleet mix to include smaller vans, flex fuel vans and incorporated GPS to help reduce the miles per day. These simple measures make both environmental and business sense.

Recycling, lesson learned.

Jack Yaeger a holocaust survivor lived n the woods of Poland during World War II. During that time Jack learned not to waste anything. After the war he immigrated to USA and settled with his wife in Oakland CA. He became and entrepreneur and his main business was recycling. He would visit plumbing and electric shop through the bay area for over 50 years recycling metal and making sure things were not going to waste. For two generation Jack visited our shop weekly. Jack has since passed away but his legacy of recycling is part of our culture here at Harry Clark Heating and Air Conditioning. We recycle refrigerants, metals, cardboard, batteries, mercury thermostats and more.

It was during a big storm and Harry Clark was slammed. A huge tree had fallen and broken a water pipe and was flooding underneath the house. Electricity was out, tree was covering the valve to turn off water and East Bay Mud evaluated and could do nothing until the tree was removed. This could be days. Bradley managed to gather a crew with a generator and pump and was at the site within 30 minutes of the call. The guy pumped all the water out from under the house and with unbelievable ingenuity managed to get access to the water source and identify the broken pipe and clamped it down stopping all the water from rushing under house. It was a Superman moment!!! Thank you Harry Clark for responding to a 911 situation with all that was going on and being better than anyone expected!!!

I have had great results with Harry Clark Plumbing. They did such a great job from the 2000's until present day (yesterday- my old sump pump finally gave out) The sump pump well they installed has gotten compliments from drainage consultant to electrician working in that area of the crawl space- anyone who happens to be working in that area of my house has commented that "they did a very nice job on that pump well". Yes, it's true I'm sump pump proud. Thank you Harry Clark! On time, responsive, communicative, dependable, great work!

The entire company from the people that helped schedule the jobs to the service professionals that came out to our home were fantastic. We had a 100+ year old home in Oakland that had a gas line that was leaking in the kitchen and they were able to immediately identify the leak and replace the valve. They also hooked up our new gas range and did all the appropriate tests to confirm proper function and no additional gas leaks in the home. Separately we had them come out to install a new toilet in our downstairs half bath. Within an hour the new toilet was installed and running better than we could have hoped saving us water. Fast, efficient and fair priced for each service. Communication was outstanding We could not be happier and highly recommend.

Positive: Professionalism, Quality, Responsiveness

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!

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.
