Diagnosed kitchen sink plumbing issue and identified non-functional hot water shut-off valve. Upon inspection of under-cabinet plumbing components, confirmed valve failure on hot water side requiring replacement. Provided customer with estimate for complete valve replacement service.
Investigated customer complaint of inaccurate outdoor temperature readings on Lennox thermostat, confirming sensor reads 10-15 degrees higher than actual temperature due to direct sunlight exposure and heat radiation from dark exterior wall. Evaluated thermostat placement concerns related to nearby wood-burning stove causing temperature inconsistencies in distant rooms. Recommended monitoring temperature discrepancies at different times and discussed installation of remote temperature sensors to improve comfort in rooms affected by uneven heating.
Performed comprehensive tune-up on 3-year-old Carrier furnace, verifying all components are functioning properly, including flame sensor, igniter, blower assembly, draft motor, burners, and control board. Combustion analysis confirmed safe operation. Identified issue with stripped screw hole on heat exchanger backplate causing condensation pooling in upper furnace compartment. Will provide estimate for backplate replacement or complete heat exchanger replacement as necessary.
Performed routine maintenance on 14-year-old Carrier furnace. Verified safe combustion with Testo analyzer showing proper efficiency readings, cleaned flame sensor and blower wheel, confirmed proper gas pressures and electrical connections, and ensured condensation drains were clear. System operating correctly with thermostat maintaining 72° indoor temperature.
