Responded to service call for zone damper system alarm activation. Inspected automatic zone dampers controlling airflow distribution between heating zones and diagnosed alarm condition. Observed condensate pump installation showing signs of corrosion at pipe connections, which was documented with photos for maintenance records.

Performed routine maintenance tune-ups on two residential furnaces, one approximately 13 years old and another approximately 20 years old. Conducted comprehensive system inspections including combustion analysis using Testo 310 analyzer, which measured carbon monoxide levels at 5 ppm and 2 ppm, confirming safe operation within acceptable parameters. Both units found operating properly with no issues identified during service visit.

Completed replacement of two residential furnaces at the property—one serving the main house and one serving the garage. Removed existing units and installed new Lennox furnace systems with proper venting, gas line connections, electrical wiring, and ductwork integration. All installations include new PVC venting routed vertically, properly connected gas valves, blower motor assemblies, and control wiring. Wall-mounted thermostats installed and wired for each zone.
