Pool Heater Repair Services in Siesta Key
A heater that will not fire leaves the pool cold and the season short. We repair every part of the heater that keeps your pool warm when you want it.
Gas Pool Heater Repair
A gas heater that will not fire leaves the water cold when you want to swim. We diagnose the ignition, gas valve, and heat exchanger so the unit lights and heats the way it was built to.
Heat Pump Diagnosis and Repair
Electric heat pumps pull warmth from the air, and a failed compressor or fan leaves the pool cold. We test the refrigerant circuit, fan motor, and controls to find the real fault.
Pressure and Flow Switch Repair
A heater will not run if the pressure switch never closes, because the system thinks water is not flowing. We repair and replace flow switches so the heater fires on demand.
Thermostat and Control Board Repair
A bad thermostat or control board can keep the heater from reaching set temp or stop it from starting at all. We repair controls and recalibrate the set point so the pool holds the heat you want.
Heat Exchanger Service
A scaled or leaking heat exchanger wastes heat and can shut the unit down. We clean and service exchangers, and we tell you honestly when a replacement is the right call.
Bypass Valve and Plumbing Repair
The plumbing around a heater controls whether water runs through it, and a stuck bypass valve can starve the unit or overheat it. We repair valve actuators and heater loop plumbing.
Brands and Materials We Work With
We service the pool heater brands that show up most often on Siesta Key routes, including Pentair MasterTemp and Raypak gas heaters, plus Hayward and Pentair heat pumps. That covers the common ignition modules, burners, and heat exchangers that run on these pools.
We also work with the gas lines, the plumbing unions, and the automation controls that tie the heater into the rest of the pad. When a part is at the end of its life, we source the matching replacement and set it up the right way so the repair holds through the heat and the storms.
How a Pool Heater Repair Visit Works
Three clear steps from the first call to a heater that fires when you want it.
We Diagnose the Heater
We run the heater, read the pressure and temp, and test the ignition, controls, and safety switches to find the real cause of the trouble, not just the symptom you see.
- Ignition and gas valve testing
- Pressure and flow switch checks
- Honest assessment of what is wrong
You Get a Written Quote First
Before any work starts, we send a clear written quote covering the repair or replacement and the parts it needs, with no pressure to say yes.
- No surprise add-ons later
- Clear scope of work
- Owner-operated, so the quote is accurate
We Complete and Verify the Repair
Once you approve, we do the work, fire the heater, and confirm the water is warming to set temp before we leave.
- Parts installed correctly
- Heater tested under load
- Pool warming right
Warning Signs You Need Pool Heater Repair
A heater rarely fails all at once. These are the early signs that the ignition, the burner, or the heat exchanger is going wrong.
- The heater runs but the water is not getting any warmer
- The heater will not fire or clicks but never ignites
- The heater shuts itself off shortly after starting
- You see water pooling or a leak around the heater base
Repair or Replace: What Is Included
We always start with repair, because a cleaned burner, a replaced igniter, or a descaled heat exchanger can add years to a heater for a fraction of what a full replacement costs. We tell you honestly when a repair will hold and when the heat exchanger or the cabinet is too far gone, so you are not paying for a fix that fails next month. Every job is different so we quote after a free walkthrough, and we give a free written quote after seeing your situation, no pressure.
When a replacement is the right call, we size the new heater to your pool and your gas line, plumb it in, and set the controls so it heats the way it was built to. That includes the gas tie-in and the automation settings, so the new heater runs right from day one. You get one crew handling the full job, start to finish.

Pool Heater Repair Conditions in Siesta Key
What changes about heater repair when we get to Siesta Key, and how we handle it.
Barrier Island Salt Air Corrodes Burner Trays
Siesta Key is a barrier island, so the heater cabinets here sit in unbuffered Gulf salt air that none of our mainland routes see, and that salt corrodes the burner components, the igniters, and the heat exchangers inside gas heaters faster than a few miles inland. A gas heater that ran clean for years on the mainland can fail suddenly on one of these island lots because the salt eats through the metal burner trays and the flame rail. We open the burner tray on every heater visit, check the metal for corrosion, and replace the corroded parts before they cause a no-heat call, because that island salt exposure is the single biggest difference between heater repair here and on the mainland routes.
Wind-Driven Salt Spray on the Beachfront Cabinets
The beachfront lots at Crescent Beach and Turtle Beach catch the wind-driven salt spray straight off the Gulf, so the heater cabinets on these pads take a heavier salt load than the sheltered Siesta Village lots even a few blocks inland. That spray bakes into the cabinet paint, the wiring insulation, and the rubber gaskets, and a heater that shuts itself off right after starting is often tripping a corroded or salt-damaged safety switch, not a problem with the burner itself. We inspect the cabinet, the wiring, and the safety switches on every visit and replace the salt-damaged parts before they cause a no-fire call.

Pool Heater Repair FAQ
Straight answers to what Siesta Key homeowners ask before hiring pool heater repair.
How do I know if my pool heater needs repair on Siesta Key?
Common signs are a heater that runs but does not warm the water, a unit that clicks but never ignites, a heater that shuts itself off shortly after starting, and water pooling around the base. Siesta Key is a barrier island, so the heater cabinets here sit in unbuffered Gulf salt air that none of our mainland routes see, and that salt corrodes the burner components, the igniters, and the heat exchangers inside gas heaters faster than a few miles inland. We run the unit, read the pressure and temp, and tell you exactly what is wrong before any work starts.
Do you repair both gas pool heaters and heat pumps?
Yes. We service gas heaters from Pentair, Hayward, and Raypak, and we also work on electric heat pumps that pull warmth from the air. Gas heaters usually fail at the ignition, gas valve, or heat exchanger, while heat pumps tend to fail at the compressor, fan motor, or refrigerant circuit. We test the right components for whichever unit you have.
Why does my pool heater keep shutting off?
A heater that shuts off right after starting is almost always tripping a safety switch, and the usual culprits are a low pressure or flow switch, a high limit switch, or poor water flow through the heat exchanger. The unbuffered salt air on Siesta Key corrodes the flow switch terminals and the safety switch contacts faster than on the mainland, so a switch that tested fine last year can fail suddenly here. We test each safety switch and the flow path to find which one is cutting the unit out.
What does pool heater repair cost?
Every job is different so we quote after a free walkthrough. The repair depends on what is wrong, which parts are needed, and how much labor the job takes. We give a free written quote after seeing your situation, no pressure, so you know exactly what you are approving before anything starts.
Can a pool heater be repaired or does it need replacing?
Many heaters can be repaired. A failed igniter, a bad gas valve, a worn flow switch, or a scaled heat exchanger are all fixable for far less than a full replacement. We always start with repair and tell you honestly when the heat exchanger or compressor is too far gone. When a replacement is the right call, we size the new unit to your pool and install it to code.
