Inlet Filter and Air Intake Cleaning in Reno
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 correctly and the burner breathing properly.

Commercial Tankless Rack Maintenance in Reno
Restaurants, salons and multi-family buildings often run several tankless units linked together. Commercial racks see heavy use and scale faster than home units. We descale each heater, check cascade controls and balance the load across the system. Quarterly or semiannual service keeps the hot water flowing during peak hours.

Rinnai units are popular for their efficiency and compact design. Our Rinnai-specific maintenance includes cleaning the air intake filter, checking the flame sensor and verifying the operation of the bypass valve.

Annual Tankless Water Heater Inspection in Reno
An annual inspection of your tankless water heater in Reno is a smart measure against costly repairs. Our thorough 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, providing recommendations to keep your system running smoothly all year long, through hot spells and cold snaps alike.
Residential Tankless Water Heater Flushing in Reno
Homes around Reno that rely on private wells should test for hardness and other minerals before choosing treatment equipment. Hard water can lead to significant mineral buildup in tankless water heaters. Our residential flushing service in Reno involves circulating a descaling solution through your unit's heat exchanger to remove calcium and magnesium deposits. This process restores efficiency, prevents overheating and extends the life of your appliance, so your family gets continuous hot water without interruption.
Error Code Diagnostics in Reno, NV
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.

Noritz Tankless Water Heater Descaling in Reno, NV
Noritz tankless heaters are known for their solid build. Our descaling service for Noritz units focuses on their intricate heat exchangers, which can be prone to scale buildup from mineral-rich water.

Frequently Asked Questions About Tankless Water Heater Maintenance in Reno
Most tankless descaling visits cost $175 to $350, depending on brand and access. Adding an isolation valve kit typically runs $150 to $300 more.
A cold water sandwich can come from restricted flow, a dirty inlet filter or a flow sensor not reading correctly. Descaling and filter cleaning often improve it.
Tankless water heater maintenance focuses primarily on descaling the heat exchanger and checking electronic components for efficiency. Hot water tank maintenance usually involves flushing sediment from the bottom of the tank, checking the anode rod for corrosion and inspecting the pressure relief valve. Both aim to prolong life but address different system needs.
A typical tankless water heater maintenance service, including flushing and inspection, generally takes 1 to 2 hours. The exact time can vary depending on the unit's condition, the amount of scale buildup and whether any minor adjustments or repairs are needed during the visit.
Many tankless water heater manufacturers require proof of regular, professional maintenance to keep your unit's warranty valid. Skipping annual service can void the warranty, leaving you responsible for costly repairs that would otherwise be covered. Always check your specific warranty terms.
If you have isolation valves, a pump and the right solution, a handy homeowner can do it. A pro visit also checks gas pressure, venting, sensors and condensate, which a DIY flush skips.
Once a year is standard, and homes with very hard water and no softener may need it every six to nine months. Heavy users and commercial units need it more often.
With regular descaling, many tankless heaters last 15 to 20 years. Neglected units in hard water can fail in under half that time.
