Pool Heater Repair in Scottsdale, AZ

We repair gas and electric pool heaters from the major brands Scottsdale pools run, including Pentair MasterTemp and UltraTemp, Hayward HeatPro and H-Series, and Jandy JXi and Lite2. We carry common flame sensors, igniters, high-limit switches, and pressure switches on the truck so a lot of heater repairs finish in one visit instead of a second trip. When a part is discontinued, we find the correct modern equivalent rather than forcing a wrong fit onto your unit.

For gas heaters we also work with the gas valve, the pilot assembly, and the venting, since a heater that fires but shuts down often has a gas or airflow problem rather than a bad board. Scottsdale hard water scales up heat exchangers over time, so we check the exchanger and the flow as part of every diagnosis, because a scaled exchanger will kill a new board in weeks if the flow is not fixed first. If your heater is an older brand we are less familiar with, we tell you up front and confirm we can source parts before we start the job.

We lead with repair whenever it makes sense, because a new flame sensor, a cleaned heat exchanger, or a replaced pressure switch often gets years more life out of a heater for a fraction of a full replacement. We diagnose the actual failure and tell you exactly what is wrong, whether it is a bad igniter, a tripped high-limit, or a scaled exchanger, and we quote the repair in writing before we touch anything. If the core parts are still serviceable, we fix it and stand behind the work with our satisfaction guarantee.

When a heater is past repair, we say so plainly and quote a replacement sized and matched to your pool and your gas or electric setup, never a bigger unit than you need. We give a free written quote after seeing your situation, no pressure, and we lay out the repair option and the replace option side by side so you can choose. We never swap a whole heater just to run up the bill, and we will not sell you a replacement we would not put on our own pool.
