"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!"

"The proprieter, Mr. Hernandez, helped me select a new tankless water heater to replace my old one. He was generally easy to communicate with and did what he said he was going to do. Although this was a replacement water heater, the plumbing had to be replaced to fit the new unit. A few hours after he installed the new water heater, I noticed a minor problem, texted Mr. Hrnandez, and he was at my house an hour later, at 9:00 pm, to fix it. I have had many craftsmen work on my house over the years. It's usually pretty frustrating and aggravating. When there was a problem after other jobs, most of them told me my house was defective, admitted that the problem was their fault but refused to fix it, claimed that I did not understand the situation, or just stopped responding to my communications. Mr., Hernandez responded instantly to my text message and was at my house an hour later (at 9:00 pm) to fix the problem. He is a skilled professional plumber and an honorable person. I hope to do some significant remodeling that will require rebuilding some of my house's plumbing, and I'll try to get Mr. Hernandez to come back for the work."

"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"

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"Jeff was prompt with the initial quote via Yelp. He asked questions to find out more about the type of water heater I had. He sent a text message about 20 minutes early to let me know he was on his way. Once here, he had his mask and gloves on. He was able to assess the situation and within 45 minutes was able to complete the job. He also made recommendations on what to expect based on the age of the water heater and did recommend looking into getting another one soon. The payment was easy and affordable."
