Our Tankless Water Heater Repair Services

Tankless systems are built for long-lasting performance, but they require expert attention when something goes wrong. We offer a full range of repair services that address the most common and complicated issues these units experience.

Error Code Diagnostics

Modern tankless water heaters often display error codes when a problem arises. These codes can point to ignition issues, airflow problems, scale buildup, or internal component failures. Our technicians use advanced diagnostic tools to read these codes accurately and determine the source of the problem quickly. By identifying the issue early, we are able to provide an efficient repair that prevents further damage.

Heating Element and Burner Repair

Your tankless water heater relies on a powerful burner or heating element to deliver the steady stream of hot water you expect. When these components fail, you may notice lukewarm water or no hot water at all. We inspect the burner assembly, ignition components, and heating elements to ensure everything is functioning correctly. If repairs or replacements are required, we complete them with precision to restore your system’s full heating capacity.

Descaling and Flushing Services

Mineral buildup is one of the most common causes of tankless water heater issues, especially in areas with hard water. Scale deposits can clog heat exchangers, reduce efficiency, and trigger error codes. Our descaling and flushing services remove these deposits and help your system operate smoothly again. Regular flushing not only improves performance but also extends the lifespan of the unit.

Fixing Inconsistent Temperatures and Low Hot Water Flow

If your water temperature fluctuates or you are experiencing low hot water flow, your system may be dealing with a blocked filter, a failing component, or an internal imbalance. We check the flow sensors, filters, valves, and temperature controls to identify the cause. Once diagnosed, we make the repairs necessary to return your hot water to a consistent and reliable level.
