"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"I had a great experience with Mitko professional service for our water heater burner problem, I called a day before, and Mitko came to our house next day, he did full analysis & testing of the water heater and right after he did find out the problem and had all required parts in his company van, took him to replace and fixed within couple of hours. Excellent service with reasonable service fee!"

"Jaymie first visited to review our need for correcting a pre-existing faulty installation of a tankless water heater. He grasped our concerns at once, joined us in brainstorming a relatively simple solution, and produced a financially reasonable bid on the spot. We accepted it as far more reasonable than other bids. He arranged to have the work performed by his company within a few days. At the appointed time, Jaymie himself arrived to do the job, which pleased us greatly since he already knew exactly what needed to be done, making it unnecessary to brief a new workman. He is a very competent, friendly, and helpful person. We would not hesitate to call on him for any future plumbing needs."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"I highly recommend this company!!! He responded within minutes of my searching for a plumber. He came the next day and installed a new tankless water heater. He also found a faulty electrical outlet and repaired it as well. Quality workmanship. I will keep his number. His name was Harry."

"The service was excellent. In March of 2016, he came out to check 7 water heaters to make sure there were no problems and no chance that one of them would break down or stop functioning. He is a very conscientious contractor that would look out for your needs. The price was right, as well."

"Diego was very efficient and professional. We bought a new water heater from Home Depot, and he let us know everything we needed beforehand so that his work was really quick. He demolished our old water heater stand so that we can have it replaced with a new one also. Thanks, Diego!"
