Pool Heater Repair
Pool Heater Not Heating? We'll Get It Working Again.
A pool heater that won't fire up or can't hold temperature means cold water and wasted money. Kleen Water diagnoses and repairs gas heaters and heat pumps from all major brands.
Signs Your Pool Heater Needs Repair
Pool heaters give warning signs before they fail completely. Catching them early is almost always cheaper than waiting.
Heater won't ignite or turn on
Could be a gas supply issue, igniter failure, or control board problem.
Heater runs but water stays cold
Often a heat exchanger issue, low flow, or thermostat failure.
Error codes on the display
Modern heaters display fault codes — we know what they mean and how to fix them.
Heater cycles on and off rapidly
Short cycling usually indicates a flow problem, pressure switch failure, or overheating.
Unusual smell (gas or burning)
Requires immediate attention — could indicate a gas leak or internal component failure.
Visible corrosion or water leaks
Corroded heat exchangers or failed seals can cause expensive damage if ignored.

Gas Heater vs. Heat Pump: What's the Difference?
Gas Heaters
Gas heaters heat pool water quickly regardless of air temperature — ideal for pools used occasionally or for heating spas fast. They require a gas line and have more combustion components that can wear out.
Common repairs: igniter, thermocouple, gas valve, heat exchanger, control board.
Heat Pumps
Heat pumps extract heat from the air and transfer it to the water — very energy efficient but slower to heat and less effective in cold weather. They have compressors and refrigerant systems that require specialized repair.
Common repairs: compressor, refrigerant recharge, fan motor, control board, evaporator coil.

Pool Heater Repair in North Texas
North Texas winters are mild but unpredictable. Many Collin County homeowners use their pools year-round — especially with a heater. That means heaters here work harder than in colder climates where pools are simply closed for winter.
Freeze Damage
Winter freezes can crack heat exchangers and damage plumbing connections. If your heater stopped working after a cold snap, freeze damage may be the cause.
Corrosion from Chemicals
Imbalanced pool chemistry accelerates corrosion inside the heater. Regular water testing and balancing extends heater life significantly.
Scale Buildup
Hard water in Collin County leads to calcium scale buildup inside heat exchangers, reducing efficiency and eventually causing failure.
Seasonal Startup Issues
Heaters that sit unused for months often develop igniter or control board issues when first fired up for the season.
