Commercial Pool Heater Repair in South Florida
Same-day pool and spa heater repair across Miami-Dade, Broward and Palm Beach — Pentair, Raypak, Hayward, Jandy, Lochinvar and AquaCal, gas heaters and heat pumps. Heat exchangers, ignition, gas valves, reversing valves, TXVs and controllers, fixed right. 24/7 emergency dispatch.
A cold pool is a guest complaint, not a maintenance ticket
At a hotel, HOA, condo or club, the pool heater is a guest-facing asset. When it quits, the front desk hears about it within the hour, and a heated spa that goes cold in season can cost real bookings. That is why commercial pool and spa heater calls dispatch same-day in our queue across South Florida, with hospitality and aquatic-center failures treated as priorities.
Berne Commercial Repair services both heater technologies. On the gas side we work Pentair MasterTemp and ETi, Raypak, Hayward Universal H-Series, Jandy/Zodiac and Lochinvar — burners, igniters, gas valves, pressure switches, flame sensors, thermal regulators and heat exchangers. On the heat-pump side we work AquaCal, Raypak and Hayward — compressors, titanium exchangers, reversing valves, TXVs, defrost controls and fans. The same sealed-system depth shows up across our commercial cold plunge repair work, so a heat-pump fault gets read on superheat and subcooling, not guesswork.
We are an independent commercial service company — not a dealership and not an authorized agent of any heater brand. For in-warranty units, use the manufacturer's network first; it is free for you. Out of warranty, we are typically faster, carry the common ignition and control parts, handle refrigerant to EPA Section 608, and give you honest repair-vs-replace numbers on a scaled or corroded exchanger. See the full commercial services line for the rest of the property.

The heat exchanger is the heart and the wallet of a pool heater. Cupronickel and even titanium exchangers corrode in coastal salt air, while South Florida's hard water lays scale that insulates the tubes and chokes heat transfer. A gas heater that 'works but won't warm the pool' is usually a scaled or corroding exchanger — and the repair-vs-replace math turns on its condition.
On gas heaters (Pentair MasterTemp, Raypak, Hayward H-Series, Jandy, Lochinvar) the usual culprits are igniters, flame sensors, gas valves, pressure switches and thermal regulators. On heat pumps (AquaCal, Raypak, Hayward) it's compressors, titanium exchangers, reversing valves, TXVs, defrost controls and fans. We diagnose to the platform instead of swapping parts blind.
Every heater needs minimum water flow before it'll fire — so a pump, filter or valve problem often masquerades as a heater fault. Add thermostats, controllers, venting and combustion-air requirements, ASME stamps on large commercial units, and CO safety, and a 'simple' heater call becomes a real commercial service. That's the work we do every week.
Pool heater symptoms, likely causes & typical repair costs
Real numbers from our South Florida service tickets — parts plus labor, before any contract pricing. The $89 commercial service call covers the diagnosis and is free when you approve the repair — the fee applies only if you decline.
| What you're seeing | Most likely cause | Typical cost | Dispatch |
|---|---|---|---|
| Gas heater won't ignite or locks out on ignition fault | Failed igniter/HSI, dirty flame sensor, or a gas-valve fault | $220–$700 | Same-day |
| Heater fires then shuts off after a minute or two | Pressure switch, flame-sensor signal, or restricted exhaust/venting | $180–$540 | Same-day |
| Pool warms slowly or not at all, gas bills climbing | Scaled or corroded heat exchanger choking heat transfer | $400–$2,400 | 24–48h |
| Heat pump runs but adds no heat | Low refrigerant charge, failed reversing valve, or a TXV fault | $300–$1,800 | Same-day |
| Heat pump iced over or stuck in defrost | Defrost-control fault, low charge, or a weak fan motor | $260–$900 | Same-day |
| Heater shows low-flow / pressure-switch error | Pump, filter or plumbing restriction dropping flow below minimum | $160–$520 | Same-day |
| Water temp reads wrong or won't hold set point | Thermistor/thermostat fault or a controller needing service | $150–$420 | Same-day |
| Soot, rollout, or a CO concern on a gas heater | Burner/heat-exchanger fouling or a venting/combustion-air problem | $280–$1,200 | Same-day |
