Tankless Descaling and Flushing in Columbus
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.

Emergency Tankless Water Heater Repair in Columbus, GA
A sudden loss of hot water can be an emergency, especially on a cold morning in Columbus, GA. HGR Plumbing offers emergency tankless water heater repair to address critical failures promptly. We are available to troubleshoot issues like major leaks, complete system shutdowns or persistent error codes that prevent any hot water production. Our fast response team works quickly to restore your hot water, often on the same day.
Flow Sensor and Thermistor Repair in Columbus
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 Repair vs Replacement Cost in Columbus, GA
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 typically ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.
Emergency Tankless Repair in Columbus
A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We prioritize no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meanwhile.
Pilot Light and Ignition Repair in Columbus, GA
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Columbus, GA 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 hazardous gas problems and restores your unit's ability to heat water on demand.

Tankless Water Heater Descaling Service in Columbus
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns.

Our descaling service in Columbus involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits.
