Got good, fair ballpark quote over the phone from Alex, so knew what to expect. Got appmt scheduled for that afternoon with Brian (tech) to come check out our issue.

After getting a very high quote from a major plumbing chain, we decided to contact Water Heater…read moreMasters. We had an absolutely fantastic experience with Water Heater Masters. Alex sent our technician, Rojo, who helped install a new 40-gallon gas water heater in our indoor utility closet, and he was incredibly diligent, professional, and efficient from start to finish. Installing a tank in an inside closet can be tricky, but Rojo handled the entire job seamlessly in just 2 hours. He replaced everything with high-quality components, including: * New hot and cold water flex lines * A brand new water shut-off valve * A new gas flex line and sediment trap * Fully reworked earthquake straps (to meet California safety codes) * Properly updated T&P line and venting He also took care of the removal and disposal of our heavy 18 yr old tank, leaving the utility closet completely clean. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call Water Heater Masters and ask for Rojo. Highly recommended!

I can definitely see why they have such high marks. They do stellar work, they're honest and straight-forward, and by today's standards, they're VERY reasonable.

I'm always surprised when I call that they're available within 1-2 days. We're grateful that we now have a plumber we can call when needed.

Hired Water Heaters Only to replace a water heater in Hayward. Often the truest test of a quality…read morebusiness is how they perform when things do not go well. In my case, I have quite a story of having to go five days without hot water because the unit I received was defective. The day after the install we found the tank had shut down. After a reset and restart done over the phone with the installer assisting, the unit failed again, a short time later. The next day which was a Saturday, another technician came out to swap out a 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 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 warm 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, more expensive model of a different make from a supplier, we got a replacement installed, at no additional cost. These problems are rare, and not the fault of the installer. I could not have asked for a more timely and considerate treatment as a valued customer of this business.

As a testament to their skill, the final city inspection took all of about 20 minutes. Juan saved me money before even beginning the installation by recommending a different thermostat configuration than I had originally discussed with the main contractor. That kind of customer-centered service makes a big difference in how you remember a provider. I'll be recommending Juan and Comfort Home Heating & Air Conditioning to anyone who needs HVAC services.
