Performed diagnostic assessment on non-functional Lennox furnace exhibiting flame rollout from burner box with subsequent fault shutdown. Visual inspection revealed critical heat exchanger failure with significant cracking in the chamber adjacent to ignitor. Documented equipment condition with photos of heat exchanger, data plate, and furnace for warranty processing.
Responded to no heat complaint for 5-year-old York furnace. Diagnosed weak flame sensor signal, performed cleaning of flame sensor which restored proper microamp readings (approximately 2 µA). Conducted comprehensive system check with multimeter verification showing all other components functioning correctly. Unit now operating safely with normal heat production.
Responded to airflow concerns where certain vents had reduced heat output in a one-year-old furnace system. Diagnostic testing confirmed adequate furnace performance (118°F output) and proper airflow through all vents. Determined the issue was due to heat loss in ductwork running through uninsulated exterior wall sections. Adjusted fan speed as troubleshooting measure, then reverted to original settings when improvement wasn't observed. Recommended additional insulation around affected ductwork to resolve temperature inconsistencies.
Replaced two programmable thermostats with Honeywell T6 Lyric Wi-Fi thermostats per homeowner's request. Installed new units, connected them to the zone board, and assisted customer with setup. Verified proper system operation with all zones functioning normally.
Responded to service call for 8-12 Rheem natural gas water heater failing to maintain flame. Customer had already consulted with Rheem technical support who suspected control module issue. Upon inspection, determined customer was pursuing warranty service through original installer and did not require our plumbing services.
Completed installation of locking caps on Schrader valves on outdoor condenser unit to prevent unauthorized access. Photographic documentation was taken of the completed work as requested and forwarded to Ashly.
Responded to callback request regarding humidifier issues. Upon inspection, determined the humidifier was not responding to blower operation despite correct wiring. Diagnosed probable failure of the blower current sensing relay. Documented system condition with photos of control panel and relay components. Parts ordered for repair.
Responded to IAQ service call regarding humidity issues and window condensation. Found dirty air filter that had been pulled into the blower compartment due to restriction. Replaced filter and inspected drainage system, noting proper winter valve position on condensate line and confirming floor drain functionality.
Conducted assessment for thermostat relocation request. Customer's antique Honeywell thermostat (3-wire system) is mounted on a wire bracket. Determined that relocation would be challenging due to need for drilling through wood and drywall. Will provide customer with relocation price quote via email.
Responded to service call for leaking outdoor spigot. Diagnosed issue with defective shutoff valve controlling exterior water lines. Replaced old valve with new ball valve to restore proper function and eliminate leak.
