Pool Heater Repair & Pool Chiller Troubleshooting
Precision Temperature Control—Year-Round Comfort, Restored
When your pool won’t heat up—or cool down—it’s more than just uncomfortable. It’s a disruption to your lifestyle, your system balance, and your pool’s performance. Whether you’re working with a gas heater, electric resistance unit, heat pump, or pool chiller, All Aqua Pools delivers fast, finish-conscious repairs backed by builder-level system knowledge.
Our technicians don’t just check the obvious. We diagnose temperature fluctuations at their source—evaluating thermistors, pressure sensors, flow switches, heat exchangers, and their integration with automation systems and energy-efficient pump speeds. And if it’s time to replace, we recommend solutions that match your pool’s design, usage, and climate control goals.
From spa zones that won’t activate to chillers that can’t keep up with Florida’s summer heat, we serve homeowners in New Smyrna Beach, Daytona Beach, Deland, Palm Coast, and surrounding areas with expert heater and cooling repairs that restore control, comfort, and consistency.
Signs It’s Time for Pool Heater or Chiller Repair
Common signs your pool heater or chiller needs professional repair include:
- Pool doesn’t heat or cool as expected
- Erratic temperature swings, even with stable settings
- Heater or chiller won’t turn on, or shuts off prematurely
- Error codes or blinking lights on the control panel
- Unusual noises (clicking, grinding, or hissing) from the unit
- Automation schedules fail to activate the system
- Water feels lukewarm, even when settings are at max output
Our Pool Heater & Chiller Repair Process
From inconsistent heat to complete system shutdowns, temperature control issues require more than just parts swapping—they demand a full-system understanding. At All Aqua Pools, we take a builder-level approach to every repair to ensure your heater or chiller doesn’t just work again—it works the way your pool was designed to.
Step 1: System Inspection
We begin with a comprehensive review of your pool’s temperature control setup, including:
- Heater or chiller unit condition, connections, and age
- Flow and pressure levels, verified through pump and valve inspection
- Sensor feedback from thermistors, pressure switches, and thermostats
- Automation integration with controllers and scheduling platforms
Step 2: Targeted Diagnostics
Using calibrated tools and system mapping, we identify:
- Electrical issues, such as ignition failure, sensor misreads, or circuit board faults
- Hydraulic obstructions affecting flow through heat exchangers
- Refrigerant or compressor problems in chiller units
- Compatibility mismatches between the unit and variable-speed pumps or smart automation
Step 3: Repair or Matched Replacement
Once the issue is confirmed, we:
- Repair internal components like blowers, igniters, flow switches, or thermistors
- Flush and clean heat exchangers when buildup or scale is affecting efficiency
- Recommend matched replacements only when repair is no longer viable—ensuring the new system aligns with your pool’s design, size, and usage
Step 4: Final Calibration & Testing
Post-repair, we test and fine-tune the full temperature system, including:
- Accurate startup and shutdown timing
- Correct temperature readings and safety cutoffs
- Seamless automation response and zone targeting (e.g., spa heat-up schedules)
- Efficiency check to confirm balanced flow and proper heat transfer
What to Expect:
- Most service appointments last 2–4 hours depending on complexity
- Chiller and heat pump diagnostics may require dry weather or vault access
- All work is done with care to protect deck finishes, equipment pads, and nearby components
- You’ll receive a clear report with next steps, recommendations, and performance notes

What You Need to Know About Pool Heater & Chiller Repair
Why won’t my pool heater or chiller turn on?
This could be due to a range of issues—from flow switch failures and thermistor malfunctions , to circuit board faults or insufficient pressure caused by pump or valve problems. We run full diagnostics to isolate the cause and verify how the unit is interacting with the rest of your system.
Can I upgrade my heater or chiller without redoing everything else?
In many cases, yes. We install matched replacement units that work with your current plumbing, automation, and pump configuration. Our process ensures that flow rates, wiring, and automation schedules remain in sync—avoiding the headaches of a full system overhaul.
Will this affect my spa, water features, or automation settings?
It can, if not handled correctly. Heaters and chillers are often tied into spa zones, in-floor systems, and programmed routines. That’s why we always recalibrate your automation controls , valve actuators , and schedule timing during every repair or upgrade to keep your system fully coordinated.
Do you work with my brand or model?
We service and replace pool heaters and chillers from all leading manufacturers, including Pentair , Jandy , Hayward , Raypak , and more. If you’re unsure what you have, we’ll identify it on inspection and walk you through your best options for repair or replacement.
