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 stopped firing on a coastal route usually has salt buildup on the igniter or the burner orifice. We clean the ignition path, test the gas valve, and check the exchanger for corrosion so the heater lights clean and holds.
Heat Pump Diagnosis and Repair
Heat pumps that run without heating usually have a compressor, a fan motor, or a refrigerant problem. We diagnose the refrigerant circuit and the controls, find the real cause, and repair the component that stopped transferring heat.
Pressure and Flow Switch Repair
A heater that will not fire is often a flow or pressure switch that is not closing, not a burner problem. We test the switch against the real flow, replace it if it fails, and confirm the heater fires on demand.
Thermostat and Control Board Repair
A thermostat that reads wrong or a control board that drops the setpoint leaves the pool cold. We repair and replace thermostats and controls so the heater holds the temperature you set.
Heat Exchanger Service
A scaled or corroded heat exchanger drops the heating output and can leak. We clean, descale, or replace the exchanger so the heater transfers heat the way it was built to.
Bypass Valve and Plumbing Repair
A clogged burner or a blocked vent shuts the heater down on safety. We clean the burners, clear the vent, and confirm the unit fires clean and vents the way it should.
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 fire the unit, test the ignition train and safety switches, and read the pressure and temp to find the real cause before we quote any parts.
- Ignition and burner checks
- Pressure and flow switch tests
- Honest assessment of what is wrong
You Get a Written Quote First
We send a clear written quote covering the repair and the parts before any work starts, so you know exactly what you are approving.
- 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 complete the repair, run the heater, and verify it fires and holds the set temperature before we leave.
- Parts installed correctly
- Heater tested under load
- Unit firing and heating 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 barely warms
- The unit shuts itself off before reaching set temp
- The flow switch will not let the heater fire
- You smell gas or hear repeated clicking with no ignition
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.
