Heater not firing, showing an error code or just not keeping up?

Pool heater repair in Texas

Texas pools are heated mainly from late fall to spring. A hard freeze can crack a heater's heat exchanger or headers if water stops moving, and summer heat and hail can damage heat pump fans and coils. After a freeze, have the heater checked before you fire it up.

In Texas, gas piping for a pool heater is plumbing work that needs a licensed plumber, and many cities require a permit to replace a heater or add an electrical circuit for a heat pump. Ask your contractor who pulls the permit and check their license before work starts.

Frequently asked questions

Should I repair or replace my pool heater?

Repair usually makes sense when the heater is fairly young and the fault is a part like an igniter, sensor, pressure switch, fan motor or control board. Replacement is often the better call when the heat exchanger is cracked or badly scaled, a heat pump compressor has failed, or the heater is near the end of its life and needing repeat repairs. Ask the contractor to put both prices in writing so you can compare. Our repair vs. replace guide covers the signs.

Which pool heater brands do these contractors work on?

Common pool heater and heat pump brands include Pentair, Hayward, Raypak, Jandy and AquaCal, among others. Not every company services every brand or heater type, so tell them the brand, model and whether it is gas, heat pump or solar when you ask for a quote. A photo of the rating plate helps.

Is there a diagnostic or service call fee?

Many service companies charge a trip or diagnostic fee to find the fault. Some apply it to the repair if you go ahead. Ask what the fee is, what it includes and whether it is credited toward the repair before you book. We do not set or collect any fees.

Do I need a permit for a pool heater repair?

In Texas, gas piping for a pool heater is plumbing work that needs a licensed plumber, and many cities require a permit to replace a heater or add an electrical circuit for a heat pump. Ask your contractor who pulls the permit and check their license before work starts. Simple part swaps usually don't need one, but rules vary by city and county.
