Error Code Diagnostics in Auburn, ME
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 any work.

Condensing Unit and Neutralizer Service in Auburn
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 shielded where it runs outdoors.

Inlet Filter and Air Intake Cleaning in Auburn
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.
Navien Tankless Heater Tune-Ups in Auburn
Navien tankless water heaters often feature condensing technology, making them highly efficient but also requiring specific maintenance.
