Water Heater Installation/Repair near Cupertino

“I could not be more grateful to United for the work they did today. And I am especially grateful to my technician Chris Villa for being so professional, patient, and thorough in the work that he did. I called United for a leaky toilet, and they were able to find other problems and damage I didn't know about, and work with me on payment so I could get the repairs done that very same day! I was even given a free home inspection, checking every pipe under the house.

Do I wish it was a little less expensive? Of course I do, it's 2026 and the economy is in a downward spiral. But like I said, United worked with me on payment so I could get the repairs I needed done, and Chris was an absolute lifesaver. Whatever he's getting paid I promise you it's not enough! In less than 3 hours my flooding bathroom was fixed and several other damaged pipes and water fixtures besides!“

“Cupertino Plumbing installed a tankless water heater. Isaac and his team did an outstanding job. Prompt, clean and extremely communicative. I highly recommend“

“My water bill was extremely high this month and I had no idea why. I called pg&e and they said I had a water leak somewhere in my house. After calling around I decided on USA leak detector because they were able to get me an appointment the same day. They were able to pin point exactly where I had a leak. Steve was able to come out and fix my problem in 20 minutes which end up saving me a lot of money. He was extremely knowledgeable and didnt mind providing insight. I highly suggest them for fast and efficient work I’ll be calling USA leak detector for all my plumbing needs!“

“I highly recommend United HVAC Company for their exceptional service and professionalism-Believe we you won't regret it. Oleg and his team go above and beyond, making you feel like part of their family as they work to help you. They take the time to explain everything clearly, so you know exactly what to expect. The quality of their work is outstanding, and their pricing is very reasonable for the high standards they maintain. I'll definitely be returning to United HVAC Company for future projects!“

“Angel arrived right on time and put on shoe covers when he came in. He worked professionally and explained everything in detail. He is very knowledgeable and friendly. Before leaving, he ran multiple tests to make sure everything was working properly. Highly recommend“

“Excellent service from Stephan Reich. He was professional, knowledgeable, and diagnosed the issue within 15–20 minutes.

The $200 consultation fee is on the higher side, but it was absolutely worth it. I’d rather pay more for a skilled technician than deal with guesswork or wrong fixes. The issue was a simple air filter problem, and Stephan clearly explained system operation, maintenance, and how often filters should be changed.

They’re based in Milpitas and service Dublin as well—glad I found them. Plus, Stephan is easy to talk to and very approachable. Highly recommend.“

“Venture Plumbing replaced my house entire pipe system, they also replaced faucets, shower head as well as installing water softener for my house. All workers were very professional, worked hard and knew what they were doing. They needed to open up the walls and after the pipe work was done, the sheetrock, electrician and painting workers also did a great job! They came every day at 8 am and finished by 4:30 pm and kept the work right on schedule. I recommend highly about this company!“

“Needed a bath tub replaced.
These guys are very good at explaining how and what they can do to fix the problem. And they make sure that they give an update how the job is coming along.“

“Sewer clogged: ARS was prompt, assessed the issue and cleared the clogged sewer pipe. Great job.“

“Water was pouring out of our meter box. I called Knockout Plumbing and they responded to our home earlier than they had predicted. Martin assessed our problem and dispatched Kevin to repair the break. Kevin arrived shortly, completed the repair very efficiently, and he actually returned a while later to turn the water on after the glue was dry. Both Martin and Kevin were respectful, knowledgeable and friendly. We really appreciate Knockout Plumbing and their fine employees.“

“Ricky did a great job clearing are clogged drain. He was very professional and went above and beyond in his pride of workmanship.“

“I was a little worried when no one showed up at the scheduled time for our first appointment, but then realized I never provided them my address. I met with Israel the next day, showed him what I wanted, and he explained there was room to add a third zone to our heating/cooling system. They were able to come and do the installation earlier than expected. Ruben was punctual and a great communicator and went the extra mile when I requested he wrap one final vent strictly for aesthetic purposes. Bubak came out a few days later to wire the units and to set up the thermostat. It all went smoothly and I am super happy with the price and process. Highly recommend.“

“Friendly and professional service technician. Melvin performed a tankless water heater flush and also the plumbing inspection of my home.“

“Earlier this year I replaced our aging (and braking) gas furnace and A/C unit with a brand-new heatpump-based system. The original installer did a shoddy job and after they botched a subsequent repair attempt (under warranty) I sent them packing and called Sandium. Robert Shuper from Sandium provided a thorough analysis of the situation and recommended a code-compliant re-installation of the air handler, a better pipe layout, and updating the existing (but long defunct) 2-zone system. One of the newly installed units had technical issues and Sandium technicians troubleshooted the system in coordination with the factory, measured that all parameters were as expected, and got the system working as expected. My lesson: next time I will call Sandium right away. Highly recommended. The technicians are professional, communicate well, and know what they are doing.“

“Great service! Fixed my fridge the same day, everything was done very well. Thank you!

“Spoke with Hector about a clogged sewer line. Within an hour Alex was there, rooted out the blockage and scoped our line. He gave helpful advice about follow up work but with no sales pressure. I loved the fast friendly and professional service.“

“Knocked one star for the “24/7” messaging. There’s an answering service but not necessarily plumbers available. On the service call, Armando was great. Clear, specific recommendations and quick on the work.“

“A very honest work
Very clear, professional courteous, and also followed up the next day. Yes, of course I’m waiting for him to do the next steps, but still, I would absolutely trust him.“

“Our technician went above and beyond even cleaning the a/c unit outside & adjusting some insulation around furnace vents.“

“From the call for an appointment to completion of the work, I was pleased with the courtesy & professionalism. The young woman who arranged the appointment was sympathetic of my need & very helpful. The tech arrived within 30 minutes & described the work necessary & the cost quickly & clearly. When I said OK he began immediately & was finished in less than 2 hours. I am very pleased.“

“Juan was detailed , professional and friendly.
Very good experience. Joseph and his partner did an excellent job. Also what other company give a year warranty . That is unheard of today. The company from the receptionist to the workers are top professionals. I would give them a 10 rating.6“

“Awesome service! I had saw a leak with my water heater. Called these guys up and Victor came out within the hour. Found my water heater was busted and had another tech Fernando bring in a new one. Installed the new unit, replaced rusted tubings, added a drip pan, a drain pipe for the release valve, and an overflow tank. Whole process took 2 hours. Awesome!“

“On Sunday, I needed immediate service so I started going down the list of plumbers near me that are open 24/7.
Four different businesses didn’t answer the phone and one said they only take appointments…. What???
Drain Doctor Fremont was next and I was assured someone would be at my home within the hour. The technician was here within 30 minutes and just as quickly he had cleared the drain from the street.
Both the office and the technician were very courteous and wanted to make sure I was satisfied.
The task was completed, but I will tell you service makes all the difference!
Job well done, and it let me get back to my weekend quickly!“

“The maintenance plan is a good deal. Yearly checkups are informative and thorough. The company provides good number of options with pros and cons for any big repairs. The customer service is also very good.“

“EJ was the second company I asked for estimates and quotes. Our plumber Reymundo was very kind and courteous and experienced. For example, wore shoe covers in the house which not all plumbers have done in the past. I felt comfortable working with him as he explained everything clearly. The best recommendation was a camera inspection to understand the condition as not to upsell any unnecessary work. In fact, he recommended not to do some of my proposed work because of the older condition of the appliance and/or piping. He provided a fact based final quote for a larger repiping project for my consideration.“

“They did a fantastic job. Finished in 2 days even though it was initially scheduled to take 3. And they left the place very clean. Thanks to Christian, Laki, Alberto, and Ezequias!“

“Thank you, Bellows for saving my marriage! :) Just finished a home remodel and foolishly decided to skimp on the water heater, only to find out on our first evening there that the orange water from the old water heater was NOT going to flush out. It remained as orange as ever, and I desperately needed to replace the entire water heater asap.

After a call to the friendly staff at Bellows, and with some assistance and escalation from their manager, they somehow pulled everything together within a matter of hours and installed our new water heater the very next morning! All of this during the storm of the century to boot.

They did an amazing job from start to finish, including a few follow ups to fine tune everything to our liking, and we couldn’t be happier with the results. I am pleased to confirm our water is indeed hot, crystal clear, and my marriage is soundly intact - with only the crew at Bellows to thank. If you’re looking for a responsive, trustworthy, and fair company to work with across multiple trades - you simply can’t go wrong with Bellows.“
