Get matched with top tankless water heater installers in Vacaville, 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."

"They showed up on time. They replaced and installed a new tankless water heater unit. David and his staff are very friendly. We are happy of our newly installed unit. It turned out great!"

"Ty was great! He was very responsive, even on a Sunday night. He helped me weigh my options on tank vs tankless, and fit me in on Monday. He got my water heater replaced, tested, and working better than ever. He also got me the necessary safety equipment our previous system was lacking and was a pleasure to chat with. Thanks so much Water Heater Guyz!"

"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."

"They did a great job replacing my water heater."

"We chose BeastBay Plumbing for a complete home repipe after meeting with several companies. Ron Buris and Jovon were professional and promised great service, which is why we hired them. I requested the work be permitted. The crew worked hard, but cleanup could have been better. Unfortunately, the day after the job was completed, a newly installed pipe behind our chimney leaked, soaking our brick fireplace. They repaired it, but it leaked again a couple of days later, causing more water damage. We had to shut off our water and went without water until Monday because no technician was available Sunday. I was told someone would bring fans to dry the area, but no one came, so I rented them myself. The city later failed the inspection, requiring additional corrections. We paid quite a bit for this project. After final payment, communication became very poor. I expected better follow-up and accountability for a job of this size."

"Jason was very polite and the completed job was great. They disposed of the old tank water heater cleaned up the area and the install was completed in about 4 hrs. Very satisfied with the unit and the installation."

"Excellent from start to finish. Arrived on time, replaced our old water heater with a new one, left everything very clean and, from what I can tell, provided excellent workmanship at a very reasonable price."

"Came on time and completed the job on estimated time period.Travis very professional 👍"

"The day the service was scheduled did not go well. We were scheduled between 8 and 12, but they called in the morning to move it back to 10 to 2. I called them after 2 because we had not heard anything. The technician finally came around 3:45. I think it is very poor customer service to expect someone to wait all day for a service call. Once the technician arrived the service was done very professionally. He did find that they should have enlarged our vent with the install two years ago, and they will have to come back and do that. It makes me think they did not have proper attention to detail during the install. There also was an up-sale so that a $79 service call ended up costing us over $450."
