Pool Heater Repair in Lexington, SC

A pool without a working heater is a pool with a very short season. In the Lexington area, having reliable heating extends your swimming months from April through October — or even year-round with the right equipment.

Types of Heaters We Repair

Gas Pool Heaters

Natural gas and propane heaters provide rapid heating and are popular in the Midlands. Common issues include ignition failures, pilot light problems, gas valve malfunctions, heat exchanger corrosion, and flow switch errors. We diagnose the specific cause and repair it — not just reset the system and hope for the best.

Electric Heat Pumps

Heat pumps are energy-efficient and widely used in South Carolina’s mild climate. Problems we commonly see include compressor failures, refrigerant leaks, defrost cycle issues, fan motor burnout, and control board errors. These repairs require specialized knowledge, and our technicians are trained to handle them.

Hybrid and Solar-Assisted Systems

If your pool uses a combination of heating methods, we can diagnose and repair issues across the full system, ensuring all components work together properly.

Common Pool Heater Symptoms

• Heater won’t ignite or turns off shortly after starting
• Water doesn’t reach the set temperature
• Error codes on the display panel
• Unusual smells (gas odor near the heater)
• Loud or unusual operating noises
• Heater runs but produces no heat
• Frequent cycling on and off

Our Diagnostic Approach

Pool heaters are complex systems with multiple potential failure points. We use a systematic diagnostic approach to isolate the exact issue before recommending any repairs. We check gas supply and pressure, electrical connections, water flow, thermostat calibration, and internal components. This prevents unnecessary parts replacement and ensures we fix the actual problem.
