Testimonial:
“Words can’t express how happy we are with the exceptional service provided by Green Air and Heating! We had an issue with our Hayward pool heater that wouldn’t ignite. The night before a scheduled pool party we went to fire up the heater and were receiving an IF error code that we couldn’t seem to resolve. We called Green Air for their 24/7 emergency service and Hassan came out within an hour. He quickly identified the problem as a sensor issue and resolved it on the spot. Despite it being near midnight and having to work in the dark, Hassan was incredibly professional and helped to ensure the kids had a nice warm pool to swim in the next day. Thank you Green Air!”

Heating & Operational Issues with Your Pool Heater:
- Heater Won’t Turn On/Ignite/Stay Lit: It could be a power supply problems (tripped breakers for electric heaters), gas supply issues (closed valves, empty propane tank), pilot light problems (gas heaters), dirty filters restricting water flow, incorrect thermostat settings, or faulty internal components like ignition systems or sensors.
- Insufficient Heating: Some reasons for this could be: a dirty filter, low water flow, buildup of scale inside the heater, an undersized heater for the pool, or a malfunctioning thermostat.
- Heater Cycles On and Off: The unit turns on and off repeatedly before reaching the set temperature. This often indicates poor water flow (dirty filter, closed valve, reversed connections) or thermostat calibration issues.
- Pilot Light Issues: The pilot light won’t light or stay lit. This could be caused by low gas pressure, inadequate air supply, improper venting, a dirty or damaged pilot assembly, or a faulty thermocouple.
Physical Problems with Pool Heaters:
- Unusual Noises: Whining, grinding, or banging sounds can indicate debris inside the unit, loose components, or low water flow causing overheating.
- Leaking Water: Leaks can come from loose connections, damaged gaskets or seals, cracks in the heat exchanger, or corrosion. Sometimes, condensation can be mistaken for a leak, especially when heating cold water.
- Corrosion/Rust: Pool chemicals and water exposure can cause internal components like heat exchangers or headers to corrode, potentially leading to leaks or inefficiency. You might see rust chips near pool returns.
- Dark Exhaust/Soot: This usually points to improper combustion, often caused by low gas pressure, inadequate air supply, or venting obstructions.
