Bryan came out and gave us a no BS assessment of what we needed to replace our tank with a tankless system. He answered all our questions and his suggestions proved to be exactly the right call. On installation day he showed up on time and finished ahead of schedule — then came back that evening to walk us through how everything works. Support local business. Support Harris Water Heaters.

★★★★★Repair · San Jose
Harris was assigned by our warranty company. They responded the same day — within an hour — had the parts for the repair, and told me my unit had a recall. They had those parts too. The whole job took about an hour. Tech George was great. I couldn’t ask for a better outcome.

The technician, Lee, was very good. He explained what he was going to do before he started working. He also took pictures before and after. He also discussed options, "what if" and what to expect. The van is loaded with equipment and parts seemingly able to fix any plumbing problem. Lee was personal, cheerful and professional. He knows what he is doing." It all started when I received a call this morning from who I think is Laurie. She was cheerful, understandable and very easy to work with. Lee and Laurie gave me a favorable impression of Harris Water Heaters. Very good. I would do business directly with them.

My shower was lukewarm yesterday morning but only realized about 4:00 pm that pilot light was out. Unable to restart it, PG&E sent a technician at about 6:30 pm and he diagnosed a faulty controller. Luckily I have a warranty with First American and submitted a claim at about 8:00 pm and they assigned Harris Water Heaters. Randy arrived at 8:30 am this morning and quickly replaced the faulty unit. Very happy with the efficiency and seamless repair. Highly recommended.

Bryan arrived on time to replace our 28 yr old water heater. The week before he presented in detail all my different replacement options. He is very personable and an excellent technician. He completed the job on time and on estimate. I highly recommend Bryan and Harris Water heaters and will definitely use them for future projects.

★★★★★Replacement · Antioch
I called my home warranty on a Friday and after speaking to them they were apprehensive that my water heater would be resolved that day and I would be out of hot water for the whole weekend. Soon after, I received a call from Harris Water Heater and the receptionist said they could send someone out in 10 minutes. Jorge the tech came out and quickly resolved the issue. I was surprised and very happy that it all worked out and was fixed so quickly. Would recommend.

★★★★★Installation · Palo Alto
Jake and Jose were very helpful and knowledgeable. They explain each step and the pros and cons of various options — which makes a lot of sense. They installed a new water heater quickly and also cleaned out all the sediment in my faucets.

★★★★★Replacement · Pleasanton
Chuck was outstanding. He reviewed the current installation, made the necessary changes, and installed a new water heater and expansion tank in a little more than two hours. Personable, excellent job. This company only does water heaters — and it shows. I would absolutely use them again.

★★★★★Tankless conversion · Bay Area
Bryan gave us a no BS assessment, answered every question, and his suggestions proved to be the right call. Installation day: on time, finished ahead of schedule. Then came back that evening to walk us through how it all works. Support local business. Support Harris Water Heaters.

★★★★★Replacement · Castro Valley
We saw the Harris van parked in a driveway. My husband knocked on the door and Bryan said he could come over in half an hour. He came ready to go with a new water heater and installed it right away. Fast, professional, and reasonably priced. I highly recommend him.

★★★★★Repeat customer · Bay Area
We’ve had Bryan replace water heaters for us twice, in two different homes. He’s affordable, fast, and does excellent work. He explains what’s needed and why, doesn’t leave a mess, and cleans up after himself. Personable, very friendly and professional.

Lee arrived quickly, identified the problem, and solved it fast with no upselling. I’d recommend him to anyone who needs service.

Best customer service on a water heater, ever. We had three leaks and needed a new unit. Joseph showed up in a heatwave with a great attitude.
