Most pool heaters in Lake Havasu are gas-powered (natural gas or propane), though some are electric or heat pump models. The first step is to inspect all gas lines, fittings, and electrical connections for signs of leaks, corrosion, or loose wiring.

• Use a gas leak detector or soapy water to check fittings.

• Look for frayed wires, burnt connectors, or tripped breakers.

The heat exchanger transfers heat from the combustion or electrical source to the pool water. Over time, Arizona’s hard water can cause mineral buildup and calcium scaling, reducing heater efficiency and causing premature failure.

• Check for rust, white crusty deposits, or leaks.

• A chemical descaling treatment or acid wash may be necessary.
  If ignored, a damaged heat exchanger can lead to poor heating performance or total system replacement.

Desert dust and windstorms common in the Lake Havasu area often clog filters, air intakes, and burner assemblies. Restricted airflow leads to incomplete combustion and reduced heat output.

• Remove and clean the filter screens and burner trays.

• Use compressed air to clear dust from the combustion chamber.
  Regular cleaning improves efficiency and prevents ignition problems, saving both gas and maintenance costs.

Pool heaters rely on sensors and switches to regulate temperature and ensure proper water flow. Over time, pressure switches, thermostats, and flow sensors can malfunction due to scale buildup or age.

• Test temperature accuracy with a digital thermometer.

• Ensure water flow rates meet manufacturer specifications.
  If readings are inconsistent or the heater cycles on and off, it may indicate a sensor or switch failure requiring professional diagnosis.

Gas heaters need clear venting for safe operation. In desert regions, vents can easily become blocked by sand, insects, or small debris. Restricted exhaust can cause dangerous carbon monoxide buildup and poor combustion.

• Inspect flue pipes for rust, corrosion, or obstructions.

• Confirm that ventilation meets Arizona safety codes.
  If you notice soot or black residue, contact a professional technician immediately.

Water leaks around the manifold or plumbing joints often signal internal corrosion or failing seals. Even small leaks can damage electrical components and lead to system failure.

• Check for damp spots, corrosion marks, or dripping connections.

• Replace gaskets or seals as needed to prevent costly damage.

In Mohave County’s dry climate, these leaks can evaporate quickly, making them easy to overlook — regular inspections catch them early.

To keep your pool heater efficient and safe, schedule an annual inspection with a certified pool equipment repair specialist in Lake Havasu City and Mohave County, Arizona. Professional technicians use diagnostic tools to measure gas pressure, test safety sensors, and identify hidden issues before they cause breakdowns.
Routine professional maintenance not only ensures compliance with warranty requirements but also maximizes your heater’s lifespan in Arizona’s challenging desert environment.
