Pool Equipment Service & Heater Repair in Arizona

These businesses hold an Arizona ROC C-6, CR-6 or R-6 Swimming Pool Service and Repair license, or are ROC-licensed pool contractors whose name mentions service, repair or maintenance. They are a good first call for a heater that has stopped working or needs replacing, but not every service company works on every heater type, so ask before you book.

Why choose this

  • Service-focused companies are often the quickest option when a heater stops working.
  • Many offer ongoing maintenance, so one company can look after the pump, filter and heater.
  • Can tell you whether a repair or a replacement makes more sense.

Things to consider

  • Not every service company works on every heater type or brand.
  • Electrical or gas supply work may need another licensed trade.
  • Parts availability can affect repair timelines for older heaters.

Questions to ask

  • The contractor's Arizona ROC license number and class, so you can confirm it on the ROC contractor search.
  • Who pulls the permit (and any separate electrical, plumbing or gas permit) and whether permit fees are included.
  • The heater make, model and output, and how they sized it for your pool. Ask them to show the calculation.
  • Warranty terms: manufacturer warranty on the equipment and the contractor's own warranty on labor.
  • Whether they work on your heater brand and type (heat pump, gas or solar).
  • A written diagnosis and price for repair vs. replacement.
  • Whether there is a trip or diagnostic fee, and whether it is credited toward the repair.

My pool heater stopped working. Repair or replace?

Ask a licensed contractor for a written diagnosis that covers the failed part, the repair price and the replacement option. Age, parts availability and warranty status all matter. Get 2–3 written quotes for a replacement.
