Heating Repair, Install & Replacement in Warwick, RI

Arrived on site and performed a visual inspection of the Lennox heating system and Noritz NR98-DVC tankless water heater. Inspected accessible electrical connections, internal components, piping, and overall equipment condition. Observed signs of aging and accumulated dust and debris. Recommended a comprehensive deep cleaning of the tankless water heater, including burner assembly, heat exchanger, flame sensor, combustion fan, and accessible internal components, followed by combustion testing and operational verification. Performed descaling service on the Noritz NR98-DVC natural gas tankless water heater. Isolated the domestic water supply and circulated an approved descaling solution through the heat exchanger to remove accumulated mineral deposits, scale, and sediment buildup.

Flushed the heat exchanger thoroughly with clean water, inspected and cleaned the cold-water inlet filter, and restored normal water flow. After completing the descaling procedure, checked accessible plumbing connections for leaks and tested the unit for proper ignition, hot water temperature, water flow, and overall operation.
