Pool Heater Repair in Geneva & the Fox Valley, IL

Diagnosed by people who read the water, not just the fault code.

Aqua Vida Custom Pools repairs pool heaters throughout the Fox Valley, including Pentair, Raypak, and Hayward gas heaters and heat pumps, on units we did not install. Most no-heat calls trace back to flow rather than the heater itself: a dirty filter drops flow below what the pressure switch needs and the heater refuses to fire by design. The failures that are genuinely the heater are usually chemistry, because the heat exchanger is copper and acidic pool water corrodes it from the inside. We diagnose the cause, not just the symptom, so the same part does not fail again next season.

  • Freeze-damage assessment on heaters that did not survive winter
  • The chemistry correction that stops it happening again

Heater repair cost depends entirely on which part failed, and that is not knowable from a phone call. Diagnosis comes first, then you get the number and the repair-or-replace recommendation before any work starts.

Pool Heater Repair FAQs

Answers to the questions Fox Valley pool owners ask us most.

Start with flow, not the heater. A dirty filter or a clogged basket drops flow below what the pressure switch requires, and the heater refuses to fire on purpose to protect itself. After that, check that the gas valve is open and other gas appliances work, confirm the thermostat is set well above actual water temperature, and write down any fault code before cycling power, because many heaters clear the code on restart. Mice and wasps nesting in the cabinet over an Illinois winter are a genuinely common cause and are usually visible once the panel is off.

Yes. Those three cover most of the heaters in the Fox Valley, and we carry the common failure parts for them. We service both gas heaters and heat pumps, including units we did not install.

Almost always water chemistry. The heat exchanger is copper, and pool water that sits acidic eats it from the inside. Water below about 7.2 pH, low total alkalinity that lets pH swing, and running the heater right after shocking are the three habits that shorten its life the most. Low flow does its own damage by letting water boil against the tubes. A heat exchanger that failed at five years almost never failed because the part was bad.

It depends on which part failed and how old the unit is. Ignitors, pressure switches, thermostats, gas valves, and control boards are routine repairs at almost any age. A failed heat exchanger on a heater past ten years is usually the point where replacement makes more sense, because the exchanger is the expensive part and the rest of the unit has aged alongside it. We tell you which situation you are in before any work starts.

Eight to twelve years is the normal range for a gas heater here. Which end you land on is decided almost entirely by water chemistry and by whether the heater was properly winterized every fall. Freeze damage and acidic water are what take heaters out early, not hours of use.

That is a winterization failure surfacing, not a spring failure. Water left in a heater over an Illinois winter freezes and splits the exchanger or the header, and nothing looks wrong until the first time you try to fire it. This is the most common heater repair we see in spring, and it is the reason a proper blow-out at closing matters.
