Ignition Failure Repair in Reno, NV
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.

Commercial Tankless Water Heater Repair in Reno
Commercial tankless water heaters in Reno face heavier usage and require robust repair solutions. Whether it is for a restaurant, hotel or office building, we understand the urgency of maintaining hot water availability. 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 Reno
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 a smart move for most homes on hard water.

Pilot Light & Ignition Repair in Reno, NV
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Reno, NV diagnoses issues with igniters, flame sensors and gas valves. We confirm proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents dangerous gas problems and restores your unit's ability to heat water on demand.

Condensing Tankless Repair in Reno, NV
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 checked for slope and sagging.

Frequently Asked Questions About Tankless Water Heater Repair in Reno
The cost of tankless water heater repair in Reno 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.
We service Navien, Rinnai, Noritz, Rheem, Takagi, A.O. Smith, Bosch, Stiebel Eltron and EcoSmart units, among others.
Minor repairs usually do not require a permit. If the repair involves major changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Reno building department may be necessary. We handle all required 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.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still wise.
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 many of these problems.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a couple of years.
