Commercial Tankless Water Heater Repair in Frankfort

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.

Ignition Failure Repair in Frankfort, KY
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 reliably.
Gas Tankless Water Heater Repair in Frankfort
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 Frankfort perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Condensing Tankless Repair in Frankfort, KY
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 confirm proper drainage. PVC venting is also inspected for slope and sagging.
Tankless Descaling and Flushing in Frankfort
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 Water Heater Descaling Service in Frankfort
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Water softeners are a popular upgrade in Kentucky homes, protecting tank water heaters, faucets, and appliances from mineral buildup. Our descaling service in Frankfort involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.
