Condensing Tankless Repair in Kendall, FL
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 confirm proper drainage. PVC venting is also checked for slope and sagging.

Tankless Water Heater Descaling Service in Kendall
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Many wells in Florida produce water with a sulfur smell or high iron, which often calls for filtration to protect fixtures and appliances. Our descaling service in Kendall involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.
No Hot Water Tankless Repair in Kendall
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 Kendall will thoroughly diagnose the root cause, whether it is a faulty igniter, a pressure sensor fault or mineral buildup. We carry common replacement parts for fast fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.
Ignition Failure Repair in Kendall, FL
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
Flow Sensor and Thermistor Repair in Kendall
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 failed parts. Temperature becomes steady again once readings are correct.
Tankless Descaling and Flushing in Kendall
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.
Tankless Water Heater Error Code Diagnostics in Kendall, FL
Modern tankless water heaters display error codes to indicate specific problems, from flow rate issues to combustion errors. Our experts in Kendall, FL are trained to interpret these codes accurately, using specialized diagnostic tools to pinpoint the exact component failure. This precision allows us to quickly order the correct parts and perform targeted repairs, saving you time and money. We address codes related to burner failures, fan issues and temperature sensor errors, and more.
