Pilot Light and Ignition Repair in Kannapolis, NC
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Kannapolis, NC diagnoses issues with igniters, flame sensors and gas valves.

Emergency Tankless Repair in Kannapolis
A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We put first 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.
Commercial Tankless Water Heater Repair in Kannapolis
Commercial tankless water heaters in Kannapolis 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 serious scaling issues. We focus on fast, efficient service to minimize disruption to your business operations.
Ignition Failure Repair in Kannapolis, 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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Navien Tankless Water Heater Repair in Kannapolis
Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems. HFN Plumbing provides specialized Navien tankless water heater repair in Kannapolis, addressing common problems like ignition failures or condensate drain blockages. Our team is familiar with Navien's parts and troubleshooting protocols, delivering a precise and effective repair that maintains your unit's high efficiency.
Condensing Tankless Repair in Kannapolis, NC
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.
Flow Sensor and Thermistor Repair in Kannapolis
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.
