A. PREVENTATIVE MAINTENANCE Outdoor Unit Inspection Remove debris from around the unit to maximize airflow and efficiency Inspect foundation, base pan, enclosure, and control box for stability, debris, and corrosion. Verify and lubricate condenser fan motors, check belt tension. Inspect compressor, line sets, and measure voltage/current. Inspect condenser coils; clean as required to maintain performance. Check refrigerant levels, high/low pressures, and signs of leaks. Test electrical components disconnect, wiring, contactors, and overload protection. Indoor unit inspection Change all filters quarterly, clean reusable filters if applicable. Inspect ductwork for leaks, condensate damage, and proper airflow. Inspect burner assembly, heat exchanger, and clean components as necessary. Verify condensate drainage systems: clean lines, pumps, and treat algae buildup. Test flue systems, gas piping, and ignition systems for safety and performance. Inspect and lubricate blower assembly, adjust belts, pulleys, and couplings. Clean indoor cabinet enclosures and inspect for hazards. Verify gas shut-off valves and ensure electrical components are operational Specialized services Annual belt replacement and condenser coil cleaning (regardless Annual refrigerant acid test for predictive analysis. Seasonal preparation: ensure systems are optimized for weather changes. B. REPAIR SERVICES Identify and quote repairs during maintenance visits. Obtain written approval from Facilities Management before proceeding. Provide 24/7 emergency repair services with a 2-hour response time. Note: Repair services are excluded from the preventive maintenance pricing and will be billed separately upon approv
