Tankless Repair vs Replacement Cost in Chico, CA
Descaling service typically costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed typically ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

Flow Sensor and Thermistor Repair in Chico
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.

Our team is familiar with Navien's parts and troubleshooting protocols, delivering a precise and effective repair that maintains your unit's high efficiency.
Ignition Failure Repair in Chico, CA
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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights every time.
Recirculation Pump Repair in Chico
Many tankless systems use internal or external recirculation to deliver hot water more quickly. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your routine. A properly tuned system saves both water and gas.
Condensing Tankless Repair in Chico, 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 inspected for slope and sagging.

Water hardness in Northern California varies a lot by source, with snowmelt-fed systems running soft and many inland groundwater systems running hard. Tankless heaters scale up when water is hard, so expert repair and regular descaling are what keep these high-efficiency units running for their full lifespan.

Frequently Asked Questions About Tankless Water Heater Repair in Chico
The cost of tankless water heater repair in Chico, CA can range from $150 to $800 or more, depending on the issue. Simple fixes like sensor replacements might be at the lower end, while major component replacements like a heat exchanger could be higher. We provide a detailed estimate after diagnosis.
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.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or intricate internal components should always be left to a licensed professional. DIY attempts can be dangerous and cancel warranties.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a couple of years.
We stand behind our tankless water heater repairs with a comprehensive warranty on both parts and labor. The exact warranty period will be discussed with you before any work begins, providing you peace of mind.
Error codes can be triggered by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code corresponds to a specific system malfunction.
This often comes from low gas pressure, a blocked intake or exhaust, a dirty flame rod or overheating from scale. We test each possibility to pinpoint the cause.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can also be the cause.
