Ignition Failure Repair in Ridgeland, MS
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.

Rinnai Tankless Water Heater Repair in Ridgeland, MS
Rinnai is a popular tankless brand, and its units can face challenges such as scaling from hard water or issues with their flame rod. Our technicians in Ridgeland, MS are adept at Rinnai tankless water heater repair, focusing on descaling services, fan motor replacements and resolving issues with gas valve assemblies. We make sure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Tankless Descaling and Flushing in Ridgeland
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 wise for most homes on hard water.
Recirculation Pump Repair in Ridgeland
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.
Tankless Water Heater Error Code Diagnostics in Ridgeland, MS
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Ridgeland, MS 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.
Flow Sensor and Thermistor Repair in Ridgeland
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 correct.
Gas Tankless Water Heater Repair in Ridgeland
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors. Our certified technicians in Ridgeland perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.

Pilot Light and Ignition Repair in Ridgeland, MS
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Ridgeland, MS 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.
