Tankless Water Heater Installation Services in Phoenix, AZ
Tankless water heaters, also known as on-demand systems, are a popular choice for homeowners looking for high efficiency, space savings, and endless hot water. If you are tired of running out of hot water or paying to heat a tank 24/7, a tankless unit might be the perfect solution.
Switching to Tankless Hot Water
Tankless systems heat water only when you need it, eliminating the standby energy loss of traditional tanks. We provide complete installation and conversion services, including:
- Sizing and selecting the right BTU/GPM unit for your family's needs.
- Safely removing and disposing of your old tank unit.
- Installing new venting and gas lines as required by the tankless system.
- Ensuring proper electrical and piping connections for peak performance.
- Converting traditional tank locations to space-saving wall-mounted units.
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.

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.

Is Tankless Right for Your Home?
While tankless systems offer significant benefits, they are not ideal for every home. We help you weigh the factors:
- Energy Efficiency: Tankless systems use up to 34% less energy than conventional storage heaters.
- Space Savings: They are compact and wall-mounted, freeing up valuable utility room or garage space.
- Lifespan: Tankless units often last 20 years or more, significantly longer than traditional tanks.
- Upfront Cost: The initial purchase and installation cost is higher than a conventional unit, but savings accumulate over time.
We provide honest advice to determine if the long-term benefits align with your budget and hot water habits.
What to Expect During Installation
Installing a tankless unit is a specialized job that differs greatly from standard tank installation. Our experts ensure every detail is handled correctly:
- Location Assessment: Confirming the venting and fuel source location is safe and compliant.
- Fuel Source Upgrade: Often, gas lines or electrical circuits need to be upgraded to handle the higher demand of the tankless unit.
- Venting Setup: Installing specific, specialized venting required for tankless exhaust.
- Final Testing: Testing the water flow and temperature settings to ensure immediate, endless hot water.
