Flow Sensor and Thermistor Repair in Huntersville
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.
Commercial Tankless Water Heater Repair in Huntersville
Commercial tankless water heaters in Huntersville face heavier usage and require durable 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 serious scaling issues. We focus on fast, efficient service to minimize disruption to your business operations.
Recirculation Pump Repair in Huntersville
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 daily routine. A properly tuned system saves both water and gas.
Gas Tankless Water Heater Repair in Huntersville
Gas tankless water heaters require correct gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors. Our licensed technicians in Huntersville perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Tankless Water Heater Error Code Diagnostics in Huntersville, NC
Modern tankless water heaters display error codes to indicate specific problems, from flow rate issues to combustion errors. Our experts in Huntersville, NC are trained to interpret these codes accurately, using specialized diagnostic tools to pinpoint the exact component failure. This accuracy 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, and more.
Ignition Failure Repair in Huntersville, NC
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.
Tankless Descaling and Flushing in Huntersville
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 a smart move for most homes on hard water.
Tankless Repair vs Replacement Cost in Huntersville, NC
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 usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

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.
Typical 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 warrant a professional inspection.
We stand behind our tankless water heater repairs with a solid warranty on both parts and labor. The exact warranty period will be discussed with you before any work begins, providing you peace of mind.

Minor tankless water heater repairs, such as replacing a sensor or igniter, usually do not require a permit in Huntersville. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
