Navien Tankless Water Heater Repair in Redmond

Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems. FHN Plumbing provides dedicated Navien tankless water heater repair in Redmond, addressing common problems like ignition failures or condensate drain blockages. Our team is familiar with Navien's parts and troubleshooting protocols, ensuring a precise and effective repair that maintains your unit's high efficiency.

Flow Sensor and Thermistor Repair in Redmond

Tankless heaters rely on flow sensors to start and thermistors to regulate temperature.

Commercial Tankless Water Heater Repair in Redmond

Commercial tankless water heaters in Redmond face heavier usage and require robust repair solutions.

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

Tankless Descaling and Flushing in Redmond

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.

Our descaling service in Redmond involves flushing the unit with a specialized 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.

Frequently Asked Questions About Tankless Water Heater Repair in Redmond

The cost of tankless water heater repair in Redmond varies a lot depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after diagnosing the specific problem.

Common signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms call for a professional inspection.

Many tankless heat exchangers carry long warranties, while other parts usually have shorter coverage. Warranties may require proof of maintenance, which we document.

Frequent causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent most of these problems.

With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a few years.

Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.

Yes, our technicians are trained and experienced in repairing all major tankless water heater brands, including Rinnai, Navien, Noritz, Rheem, Bosch, A.O. Smith and more. We carry a wide range of common parts for various models.

Regular professional maintenance, including descaling and checking all connections, is the best prevention. Installing a whole-home water softener can also significantly reduce mineral buildup in areas with very hard water.
