Water Heaters We Service
Tank, tankless, hybrid, gas, electric — every water heater eventually needs attention. We service all of them and won’t push a replacement when a repair will do.
Tank Water Heater Repair
Thermocouples, anode rods, heating elements, and T&P valves. Most repairs are same-day with parts on the truck.
Tank Water Heater Replacement
When repair isn't worth it, we replace with a properly sized unit and install code-compliant pans, expansion tanks, and shut-offs.
Tankless Water Heater Installation
Endless hot water and a smaller footprint. We size for your household and gas-supply capacity — not just the spec sheet.
Heat Pump (Hybrid) Water Heaters
Lower operating cost than electric tanks, eligible for federal and APS rebates. We'll tell you whether your home is a fit.
Annual Flushing and Maintenance
Phoenix hard water cuts a tank's life in half if it's not flushed. An annual visit pays for itself in years of extra service.
Emergency Water Heater Failure
No hot water and the unit is leaking? We respond same-day, contain the damage, and get you back to hot water as fast as the install allows.
No matter your situation, our plumbers provide service you can rely on.
Our Water Heater Services in Phoenix
Pick the service that fits your situation. Not sure where to start? Call us — most water heater diagnostics take 15 minutes and you’ll have a clear path forward.
Water Heater Repair
Pilot light won't stay lit? No hot water at the tap? Strange noises from the tank? Most water heater problems are repairable — and we'll tell you straight when they're not. Same-day service in most of the metro.
Water Heater Replacement
When the tank itself has failed — or when a repair just isn't worth it on an aging unit — we pull the old one, install the new one, and haul the dead unit away. Permit pulled, install to code, ready by the end of the day.
Water Heater Installation
First-time install in a new build, relocation to a different spot, or a fresh unit in a home that didn't have one in the right place? We size, vent, and install properly the first time.
Tankless Water Heater Installation
Switching from a tank to tankless? We handle the venting, gas supply upsize, and water connections — and we tell you up front whether your home's current setup will support the tankless unit you're looking at, or whether you'll need additional work to make it viable.
Gas Water Heater Installation
Replacing a gas unit or switching from electric to gas? We run the gas supply, handle the venting, and connect water — all to code, all in one job. Permit included.
Electric Water Heater Installation
Standard electric tank, heat pump hybrid, or a switch from gas to electric? We handle the electrical hookup coordination, water connections, and code-compliant install.
Hybrid Water Heater Installation
Heat pump water heaters cut electric bills significantly in Phoenix's climate — but they require the right space, the right venting, and the right install to work as advertised. We'll tell you whether your home is a good fit before we sell you one.
Water Heater Maintenance
Annual flush, anode rod check, and inspection — the difference between a water heater that lasts 8 years and one that lasts 14. Especially important in Phoenix's hard water.
No matter your situation, our plumbers provide service you can rely on.
