Condensing Unit and Neutralizer Service in Fremont
High-efficiency condensing tankless heaters produce acidic condensate that must be neutralized before it goes down a drain. We inspect the condensate trap, line and neutralizer cartridge and replace the media when it is spent. A clogged trap can cause shutdowns or water leaking inside the cabinet. We also check that the line is protected where it runs outdoors.
Heat Exchanger Descaling in Fremont
The heat exchanger in a tankless heater is a coil of small tubes that water races through while the burner fires. Hard water drops calcium and magnesium on those hot surfaces, narrowing the passages over time. We connect a submersible pump and hoses to the service valves and circulate descaling solution for 45 to 60 minutes. Then we flush with fresh water to rinse the system thoroughly. Restored flow means steadier temperatures and fewer shutdowns.

Inlet Filter and Air Intake Cleaning in Fremont
Every tankless unit has an inlet water screen that catches grit and scale flakes. Those screens can clog with sand and debris, especially after municipal line work. We pull and clean the screen and inspect the air intake filter, which can load up with dust and dryer lint. Clean filters keep the flow sensor reading correctly and the burner breathing properly.

Frequently Asked Questions About Tankless Water Heater Maintenance in Fremont
The cost of tankless water heater maintenance in Fremont usually ranges from $150 to $300, depending on the unit's condition, age and brand. This generally includes flushing, descaling and a complete inspection. More extensive repairs or part replacements would be quoted separately after diagnosis.
FKV Plumbing services all major brands of tankless water heaters, including Rinnai, Noritz, Navien, Bosch, State, Rheem and more. Our technicians are trained on the specific maintenance requirements and diagnostics for a wide range of models to ensure expert care for your unit.
Tankless water heater maintenance focuses primarily on descaling the heat exchanger and checking electronic components for efficiency. Hot water tank maintenance usually involves flushing sediment from the bottom of the tank, checking the anode rod for corrosion and inspecting the pressure relief valve. Both aim to prolong life but address different system needs.
The descaling process involves shutting off the unit, isolating the water lines and connecting a circulating pump to flush a specialized acidic solution through the heat exchanger. This solution dissolves mineral deposits like calcium and magnesium, which are common in hard water, restoring heat transfer efficiency.
Many tankless water heater manufacturers require proof of regular, professional maintenance to keep your unit's warranty valid. Skipping annual service can void the warranty, leaving you responsible for costly repairs that would otherwise be covered. Always check your own warranty terms.
Yes, electric models scale up on their heating elements and need flushing and filter cleaning. We also check high-amp wiring connections for signs of overheating.
Common signs include reduced hot water flow, fluctuating water temperatures, strange noises like banging or popping, error codes displayed on the unit, or a noticeable increase in your energy bills. If you observe any of these symptoms, it's time to schedule a professional inspection and maintenance.
Rinnai shows LC codes, Navien may show E003 or E030 and Noritz often shows 90 or 99 when scale or airflow is a problem. These codes usually clear after proper cleaning.
