Is your commercial pool heater failing to keep the water warm? You’ve come to the right place. At M&M Pool & Spa Services, we specialize in commercial pool heating troubleshooting and provide fast, expert solutions that restore functionality to your investment.

Whether you’re dealing with a heater not heating, ignition issues, or sensor faults, our certified technicians are ready to help businesses resolve common and complex heating problems efficiently. This article walks you through key troubleshooting tips, signs of malfunction, and the best steps to take if your pool heater is underperforming—especially tailored for commercial properties in South Florida.

Understanding Common Commercial Pool Heating Issues

Commercial pool heaters are sophisticated systems, and like any HVAC or aquatic equipment, they can develop issues over time. The sooner you identify the source, the quicker you can resume normal operation. Below are the most common problems we encounter during service calls in Miami and surrounding areas:

1. Heater Not Heating

If your commercial pool heater is running but failing to heat the water, several culprits could be at play:

  • Clogged or dirty filters reducing water flow
  • Faulty thermostat settings or calibration
  • Blocked heat exchanger preventing proper heat transfer
  • Low gas pressure or malfunctioning gas valves (for gas heaters)

An M&M Pool & Spa technician can assess your heater’s mechanical and electronic components to locate the issue quickly and recommend appropriate repairs or replacements.

2. Ignition Issues

If your pool heater won’t ignite, it could be due to a variety of component failures:

  • Defective igniter or pilot light
  • Flame sensor errors or corrosion
  • Gas line obstructions or air in the line
  • Safety switch shutdowns due to overheating or mechanical faults

Our troubleshooting process includes a step-by-step inspection of flame sensors, pressure switches, and control boards to restore reliable ignition.

3. Sensor Faults

Modern commercial pool heaters depend on a range of sensors to function safely and accurately. When sensors malfunction, the heater may shut down or operate erratically. The following are common sensor-related issues:

  • Misread water temperature due to faulty thermistors
  • Internal pressure switch failures
  • High-limit switch tripping prematurely due to scaling or poor circulation

Our Miami-Dade service team is trained to diagnose sensor faults using manufacturer diagnostic tools and can reset, replace, or recalibrate components as needed.

Signs Your Commercial Pool Heater Needs Troubleshooting

Many property managers and business owners are unaware of heater issues until complaints arise. Here are signs your system may be underperforming:

  • Delayed or no heat-up time during peak hours
  • Heater cycles on and off rapidly
  • Water feels lukewarm or cold despite thermostat settings
  • Visible error codes on electronic display panels
  • Unusual noise or vibrations during operation

At M&M Pool & Spa Services, we recommend scheduling a professional inspection if you notice any of these signs, to prevent more serious and costly damages down the line.
