Ignition & Flame Repair
A heater that will not fire usually has an ignition, a pilot, or a gas valve problem. We repair the ignition path so the heater lights reliably.

Hillside Pool & Spa diagnoses and repairs pool heaters across Round Rock, fixing the ignition, sensor, and flow problems that stop the water from warming.
A focused pool heater repair visit covers the specific problems that show up on Round Rock pools. Here is what we handle on every repair.
A heater that will not fire usually has an ignition, a pilot, or a gas valve problem. We repair the ignition path so the heater lights reliably.
A heater that runs but will not reach temperature usually has a failing sensor or thermostat. We repair the sensors so the heater reads the real water temp.
A heater that shuts off usually has a failing pressure switch or a flow problem. We repair the switch so the heater runs when water is moving.
A heater that scales or leaks usually has a heat exchanger problem from the regional water. We inspect the exchanger and plan the right fix.
A heater that errors or resets usually has a control board issue. We diagnose the board so we fix the real board instead of swapping the whole unit.
We run the heater through a full cycle and hand you a clear written diagnosis before any repair starts. Knowing the real cause is what keeps a fix from coming back.
Round Rock pools mostly run Hayward and Pentair gas heaters, with some Raypak units, and our technicians know the common failures on all three. We carry the common sensors, switches, and ignition parts on the truck, so we can often fix a heater on the first visit. Knowing the heater on your pad is what keeps a repair quick and correct. We never guess at a part.
We use genuine Hayward, Pentair, and Raypak replacement parts, because aftermarket parts fail fast and can be unsafe on a gas heater. Every part is matched to your specific heater model. We run the heater through a full cycle after every install. We never substitute a part that does not fit right. For the full scope of our pool heater repair work across the area, see our Pool Heater Repair overview page.
We diagnose the real cause, send a clear written quote, and verify the fix before we leave your Round Rock backyard.
We run the heater through a full cycle, check the ignition, the sensors, the flow switch, and the board, and trace the problem to the actual cause.
Before any part goes in, we send a straightforward written quote for the repair so you know the plan, no pressure.
We install the part, run the heater through a full cycle, and confirm it fires and reaches temperature before we leave.
A failing heater cuts your swim season short, and the longer it runs bad the more it stresses the system. These signs tell you a heater repair visit is the fastest fix.
Catching a failing sensor or a dirty ignition early is what keeps a small repair from turning into a full heater replacement.
We always start with a clear diagnosis, because the right call between repairing and replacing a heater depends on the part, the exchanger, and the age of the unit. A sensor or an ignition part often just needs a repair, while a failed heat exchanger or a cracked header usually points to a replacement. We lay out both options honestly so you can choose what fits your pool. There is no pressure to pick the bigger job.
If a replacement is the better path, we send a free written quote after seeing your situation, no pressure, and we size the new heater to your pool volume and your fuel type. You approve the scope before any work starts, so there are never surprise charges. Our goal is the fix that lasts, not the fix that gets us out the door fastest.

Heater repair in Round Rock is shaped by the regional water and the seasonal use pattern. Here is what we plan around on every repair.
The regional water carries minerals that scale the heat exchanger faster than softer water would, which is the most common cause of a Round Rock heater that runs but will not reach temperature. The scale coats the exchanger and blocks the heat transfer, and it shortens the heater life if it is not caught. We inspect the exchanger and plan the right fix, whether that is a clean or a replacement. Catching the scale early extends the heater life.
Round Rock heaters sit idle for much of the year and then fire hard in the cooler months, which wears the ignition and the flame sensors faster than a steady-use heater. A heater that will not fire after a long idle usually has a dirty or failing ignition, and we clean or replace the ignition path so it lights reliably. The seasonal use pattern is the first thing we plan around on a no-fire call. Knowing the use pattern speeds up the diagnosis.
