When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger. Our technicians in Corona will thoroughly diagnose the root cause, whether it is a faulty igniter, a pressure sensor fault or mineral buildup.

Condensing Tankless Repair in Corona, CA

Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also checked for slope and sagging.

Flow Sensor and Thermistor Repair in Corona

Tankless heaters rely on flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace faulty parts. Temperature becomes steady again once readings are accurate.

Noritz Tankless Water Heater Repair in Corona, CA

Noritz tankless heaters are known for their sturdy design, but can sometimes face issues such as flow sensor faults or venting problems. We provide dedicated repair services for Noritz units in Corona, CA, ensuring proper combustion, water flow and exhaust, which are crucial for safe and efficient operation.

Our commercial tankless water heater repair services address larger capacity units, complex manifold systems and often more serious scaling issues. We prioritize fast, efficient service to minimize disruption to your business operations.
