Ignition Failure Repair in Lebanon, PA
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 reliably.

Flow Sensor and Thermistor Repair in Lebanon
Tankless heaters use 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 Water Heater Error Code Diagnostics in Lebanon, PA
Modern tankless water heaters display error codes to indicate specific problems, from flow rate issues to combustion errors. Our experts in Lebanon, PA are trained to interpret these codes accurately, using specialized diagnostic tools to pinpoint the exact component failure. This precision allows us to quickly order the correct parts and perform targeted repairs, saving you time and money. We address codes related to burner failures, fan issues and temperature sensor errors, among others.
Recirculation Pump Repair in Lebanon
Many tankless systems use internal or external recirculation to deliver hot water faster. 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 daily routine. A properly tuned system saves both water and gas.
Navien Tankless Water Heater Repair in Lebanon
Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems.

Our team is familiar with Navien's parts and troubleshooting protocols, delivering a precise and effective repair that maintains your unit's high efficiency.
Commercial Tankless Water Heater Repair in Lebanon
Commercial tankless water heaters in Lebanon face heavier usage and require robust repair solutions. Whether it is for a restaurant, hotel or office building, we understand the importance 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 focus on fast, efficient service to minimize disruption to your business operations.
Tankless Descaling and Flushing in Lebanon
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting 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.

Frequently Asked Questions About Tankless Water Heater Repair in Lebanon
The cost of tankless water heater repair in Lebanon, PA 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.
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 professional.
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 Lebanon building department may be necessary. We handle all necessary permitting for you.
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 cause it too.
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 specialized parts, might take longer and may require a follow-up visit.
We stand behind our tankless water heater repairs with a solid warranty on both parts and labor. The specific warranty period will be discussed with you before any work begins, providing you peace of mind.
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.
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 licensed plumber.
