    We hired water heaters only to replace a tankless water heater. Not only was Loni willing to come…read moreout and discuss the various options, but also recommended we save money by reusing some of what we had. When we decided not to, Loni made sure we understood exactly what we were choosing and that it would be a good choice for us. We eventually had some other work done, and this other plumber came and pointed out all of these "issues" with the water heater. Completely scared us with visions of fire risk and heaters not working in the dead of winter, told us that this wasn't to code (even though the permit was signed off). Loni came out again. Explained everything in great detail, as to how it worked, why the other plumber was wrong. Didn't get mad that we wasted his time, just wanted to make sure that we were happy with our water heater. All in all, a fantastic experience.

    Hired Water Heaters Only to replace a residential water heater in Hayward. They came out the same…read moreday and completed the install within a few hours of the call. However, often the truest test of a quality business is how they perform when things do not go well. In my case, I had to go four days without hot water because the unit I received was defective. The day after the install we found the tank had shut down, no hot water. After a reset and restart done over the phone with the installer assisting, the unit unfortunately failed again a short time later. The next day which was a Saturday, another technician came out to swap out the heat sensor which appeared to be the problem. While changing out the part, the tech noticed that insulation near the assembly had burned, and ash was present. He removed the bad insulation, vacuumed it out and restarted the unit. It made a horrible noise, and he spent a half an hour on the phone with the manufacturer tech support trying to diagnose the problem. The noise eventually went away and he finished the repair. Unfortunately the machine shut down again, after we got one lukewarm shower. I called on Sunday, and explained that I was no longer comfortable with the unit being in our house and I wanted a replacement, of a different maker. Without hesitation they agreed, and Monday morning, after acquiring a new model of a different make from their supplier, we got the replacement installed, at no additional cost. These problems are rare, and not the fault of the installer. However, I could not have asked for a more timely and considerate treatment as a valued customer of this business.
