A sudden loss of hot water can be an emergency, especially on a cold morning in Redwood City, CA. FBL Plumbing offers emergency tankless water heater repair to address serious failures promptly.

Our rapid response team works quickly to restore your hot water, often on the same day.
Ignition Failure Repair in Redwood City, 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.
Flow Sensor and Thermistor Repair in Redwood City
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.
Tankless Repair vs Replacement Cost in Redwood City, CA
Descaling service usually 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 usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

We provide specialized repair services for Noritz units in Redwood City, CA, ensuring proper combustion, water flow and exhaust, which are essential for safe and efficient operation.
Tankless Water Heater Descaling Service in Redwood City
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Water hardness in Northern California varies a lot by source, with snowmelt-fed systems running soft and many inland groundwater systems running mineral-heavy. Our descaling service in Redwood City involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.
Gas Tankless Water Heater Repair in Redwood City
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve failures to carbon monoxide sensor errors.

Frequently Asked Questions About Tankless Water Heater Repair in Redwood City
The cost of tankless water heater repair in Redwood City varies widely 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 identifying the specific problem.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or delicate 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 few years.
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 find the cause.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require specialized tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a professional.
Minor tankless water heater repairs, such as replacing a sensor or igniter, typically do not require a permit in Redwood City. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to confirm code compliance.
Minor repairs usually do not require a permit. If the repair involves significant changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Redwood City building department may be necessary. We handle all necessary permitting for you.
Many common tankless water heater repairs can be completed within 1 to 3 hours, especially if parts are readily available. More complex issues, like extensive descaling or ordering special parts, might take longer and may require a follow-up visit.
