Tankless water heater repair & installation
Error codes, no hot water, inconsistent temperature, scale buildup, venting concerns or a tankless replacement — we diagnose the complete installation, not just the appliance on the wall.
Tankless repair & error-code diagnosis
A tankless unit can stop heating because of ignition, gas supply, venting, flow, scale, sensors, filters, controls or installation conditions. We start with the model, error history and operating symptoms, then test the system so the repair recommendation matches the actual fault.
Tankless descaling & maintenance
Mineral scale can reduce heat-transfer performance and contribute to noise, flow and temperature problems. Maintenance may include flushing or descaling, inlet-filter cleaning, visual venting and condensate checks, and review of the unit's operation and error history according to the model and water conditions.
Rinnai tankless installation & replacement
We are an Authorized Rinnai Dealer. A proper tankless installation starts with peak hot-water demand, available gas capacity, venting, electrical supply, condensate drainage and service access. When converting from a tank, those requirements are checked before the new unit is selected.

Tankless water heater questions
Do you repair Rinnai tankless water heaters?
Yes. We install and service Rinnai tankless water heaters and can diagnose common no-hot-water, temperature, flow, ignition, venting, scale and error-code problems.
Does a tankless water heater need descaling?
Many tankless systems need periodic flushing or descaling, especially where mineral buildup is significant. The interval depends on water quality, usage and manufacturer guidance.
Can a tank water heater be converted to tankless?
Often, but it is not a direct box swap. Gas capacity, venting, electrical supply, condensate drainage, water piping, available wall space and peak hot-water demand all need to be checked first.
Why does my tankless water heater go hot and cold?
Temperature swings can be related to flow rate, scale, filters, crossover, controls, sensors, gas supply, venting or other equipment-specific faults. Diagnosis should start with the model, error history and operating conditions.
