Get matched with top tankless water heater installers in Antioch, CA

"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"Alberto did an incredible job installing our Navien NPE-180A2 tankless water heater. He made the pricing fair and transparent which really helped. It’s so hard to navigate all the outrageous and confusing pricing options offered by nearly all the other plumbing companies, so I’m really grateful that he came in with a fair price from the start. Also, the install was done with such care using commercial quality materials that I know will last for years to come. Highly recommend Premier Plumbing! Thank you Alberto!"

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

"Our water heater went kaput while my spouse was out of town. Doniel from Just in Time Plumbing replaced the broken water heater just in time for my spouse to return from his trip--they missed each other by about 10 minutes. Doniel came when he said he would, answered all my/our questions, and I think he guided me/us to the right solution for our situation. He was very polite, and very personable, an all around very nice person. He was efficient and cleaned up afterwards. We had our new water heater installed in less than two days from the time of the estimate. We would definitely call again if we have any plumbing problems. S.C.Riggs"

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Aire Systems of Campbell and Saratoga truly sets the standard for exceptional service in the HVAC industry. Alton, the owner, went above and beyond to ensure I understood every aspect of the process, from selecting the right system for my small home to navigating available rebate programs. His expertise and dedication to customer satisfaction stood out as he guided me through the rebates step by step, emphasizing how beneficial they are despite the effort required. What really impressed me was Alton’s commitment to follow through—he’s not just selling systems, he’s supporting his customers well beyond installation. Daniel, the team lead installer, was equally remarkable. Always punctual and professional, he demonstrated a level of care that extended beyond the job itself. He kept me informed daily, explaining what was being done, what to expect next, and how long it would take. Knowing I had to leave for work, Daniel kindly spent time with my dogs, making sure they felt at ease while he worked. It’s rare to find a company that combines technical expertise with such personal care. Aire Systems, with Alton and Daniel at the helm, earns my highest recommendation!"

"Albert Nahman Plumbing was helpful and extremely professional. The work done by Nicholas was resourceful (involving hooking up a new heater with different requirements into a gas supply and vent system installed thirty years earlier) and carefully executed. He's a knowledgeable, courteous, and highly skilled professional."

"They fixed a major water leak and installed a new water heater all in one day. They were prompt and did a neat install. I can recommend them."

"I am a repeat customer. The are the best. Wear mask. Courteous. Friendly in a business way. I will always recommend them. Also had a hot water tank replaced 2 years ago."

"Water heater went out and decided to go with tankless. Ron is great. Quick response. On site same day. Smart. Gave me proposed costs and answered any questions. Matt did the installation. Great work. I will use Beastbay again. No doubt about it."
