Pool Heater Repair in Dallas-Fort Worth
Gas heaters and heat pumps, diagnosed and repaired across the DFW metroplex. The inspection is $99 and comes with a written quote; we are normally on site within 24 to 48 hours.
Most Heater Faults Here Start in the Water, Not the Heater
A pool heater is a heat exchanger with controls attached, and the heat exchanger is the hottest surface in the whole system. That makes it the first place dissolved minerals come out of solution. Across most of DFW the water is hard enough that this is the default failure: a coating forms inside, insulates the surface meant to transfer heat, and the heater runs longer for less result until it overheats and shuts down on its own limit.
Which way it goes depends on where you are. The NTMWD cities — Plano, Frisco, Allen, McKinney, Richardson, Garland — are on hard Lavon Lake water and scale is the usual story. Grapevine is the softest supply we work with, and there the water corrodes the exchanger instead. Dallas and the cities buying from it sit in between.
This is why a heater that keeps failing after repair is often a water problem wearing a heater's symptoms. Replacing the part without correcting the chemistry buys time rather than a fix.
We diagnose before quoting, and that includes testing the water the heater has been running on. A quote that only covers the part is a quote for doing this again.
Heater Faults We See Most
Will not fire or ignite
Ignition control, igniter, gas valve, flame sensor. Often a sensor coated rather than a component failed.
Fires then shuts down
Usually a limit or a pressure switch doing its job — insufficient flow, a dirty filter, or a scaled exchanger overheating.
Runs but will not hold temperature
Scale on the heat exchanger, most of the time. Also undersized for the volume, or losing heat faster than it adds it.
Error codes and control faults
Boards, sensors and wiring. We read the code and then verify it, because the code names the symptom rather than the cause.
Heat pump not producing heat
Refrigerant, reversing valve, fan or coil. Different machine from a gas heater and diagnosed differently.
Leaking at the heater
Exchanger, headers or fittings. Where it leaks decides whether it is a repair or a replacement, so we find it first.
Inspection First, Then a Price
1. Inspection — $99
We test the water and go over the whole pad, not only the part you called about. Problems rarely arrive alone.
2. Written quote
Parts and labour set out separately, with the markup stated rather than buried. Nothing happens until you agree it.
3. Repair
Usually within 24 to 48 hours of the call. If the pool is green or leaking onto the pad, say so and it moves up.
Repair is a standalone service — you do not need to be a weekly customer. If you are, the pad is checked on every visit, which is how most of these get caught before they fail. See weekly pool maintenance, filter and pump maintenance, or pool service in every city we serve.
Pool Heater Repair — Common Questions
How much does pool heater repair cost?
The inspection is $99 and includes a written quote. Repairs are priced per job after that and agreed before any work. Parts markup is stated on the quote.
Is it worth repairing an old heater or should I replace it?
Depends on the fault and the age. A scaled exchanger on an otherwise sound unit is worth cleaning; a corroded one on a heater near the end of its life usually is not. We give you both numbers rather than only the one we would do.
Why does my heater keep shutting itself off?
Most often a safety doing its job — a limit switch or pressure switch reacting to poor flow or an overheating exchanger. Check the filter and the water chemistry before assuming the switch is faulty.
Do you repair heat pumps as well as gas heaters?
Yes. They fail differently — refrigerant, reversing valve, fan, coil — and are diagnosed differently.
How quickly can you come out?
Typically 24 to 48 hours across the metroplex.
