Emergency Tankless Maintenance in Horace, ND
When your tankless unit stops providing hot water or shows error codes unexpectedly, HPN Plumbing offers emergency maintenance services in Horace. We diagnose issues fast, whether it's a blocked exhaust, a faulty igniter or severe scaling. Our team arrives with common replacement parts to resolve urgent problems and restore hot water service quickly, minimizing disruption to your North Dakota household.

Inlet Filter and Air Intake Cleaning in Horace
Every tankless unit has an inlet water screen that catches grit and scale flakes. Those screens can clog with sand and debris, especially after municipal line work. We pull and clean the screen and inspect the air intake filter, which can load up with dust and dryer lint. Clean filters keep the flow sensor reading accurately and the burner breathing properly.
Condensing Unit and Neutralizer Service in Horace
High-efficiency condensing tankless heaters produce acidic condensate that must be neutralized before it goes down a drain. We inspect the condensate trap, line and neutralizer cartridge and replace the media when it is spent. A clogged trap can cause shutdowns or water leaking inside the cabinet. We also check that the line is protected where it runs outdoors.
Annual Tankless Water Heater Inspection in Horace
An annual inspection of your tankless water heater in Horace is a proactive measure against costly repairs. Our complete check includes examining the gas line connections for leaks, testing the pressure relief valve, inspecting the igniter and cleaning the air intake filter. We look for any signs of wear or potential failure, giving you recommendations to keep your system running smoothly all year long, through hot spells and cold snaps alike.
Noritz Tankless Water Heater Descaling in Horace, ND
Noritz tankless heaters are known for their robust build. Our descaling service for Noritz units focuses on their intricate heat exchangers, which can be prone to scale buildup from mineral-rich water.

We also inspect the fan motor and exhaust system for proper airflow, a common area for attention in Horace.
Error Code Diagnostics in Horace, ND
Codes like Rinnai LC, Navien E003 or Noritz 90 tell us a lot about what is going wrong. We read the code history, test flame rods, flow sensors and igniters and check gas pressure at the inlet. Many codes trace back to scale or a dirty filter and clear after maintenance. When a part has failed we explain the repair and the cost before doing anything.
Navien Tankless Heater Tune-Ups in Horace
Navien tankless water heaters often feature condensing technology, making them highly efficient but also requiring specific maintenance.

A cold water sandwich can come from restricted flow, a dirty inlet filter or a flow sensor not reading correctly. Descaling and filter cleaning usually improve it.
