Noritz Tankless Water Heater Tune-Ups in Pittsburgh, PA
Noritz tankless water heaters are sturdy systems, but they still require annual tune-ups to maintain their performance through every season. Our maintenance includes checking the unit's exhaust system, confirming proper combustion air intake and verifying the integrity of the heat exchanger. We also calibrate the temperature and flow settings for the best efficiency and comfort, preventing common issues like cold water sandwiches.

Condensing Unit and Neutralizer Service in Pittsburgh
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.

Emergency Tankless Water Heater Service in Pittsburgh, PA
Even with regular maintenance, unexpected issues can arise with tankless water heaters.

We prioritize rapid response to diagnose and resolve critical problems, often related to clogged heat exchangers or faulty sensors, restoring your hot water supply quickly and safely.
Error Code Diagnostics in Pittsburgh, PA
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.
Inlet Filter and Air Intake Cleaning in Pittsburgh
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.
Commercial Tankless System Checks in Pittsburgh, PA
Commercial tankless water heaters face higher demand and require more frequent, detailed maintenance. Our service for businesses in Pittsburgh includes detailed inspections of multiple units, checking for proper gas pressure, water flow rates and exhaust venting. We look for any signs of wear on components like igniters, sensors and heat exchangers, which is crucial for businesses that rely on consistent hot water, such as restaurants or salons.

Heat Exchanger Descaling in Pittsburgh
The heat exchanger in a tankless heater is a coil of small tubes that water races through while the burner fires. Hard water drops calcium and magnesium on those hot surfaces, narrowing the passages over time. We connect a submersible pump and hoses to the service valves and circulate descaling solution for 45 to 60 minutes. Then we flush with fresh water to rinse the system completely. Restored flow means steadier temperatures and fewer shutdowns.
