About this file
This document is a Maintenance Schedule for Direct Expansion (DX) HVAC Units for FAA facilities, specifically for STTA/DX – STT/ARSR systems. The maintenance schedule provides comprehensive guidelines for periodic maintenance across monthly, quarterly, and annual intervals, including specific tasks for various HVAC equipment components such as air conditioning units, ventilation systems, control systems, motors, and emergency equipment.
Key maintenance tasks include monthly visual inspections of operating HVAC equipment, checking for vibrations, unusual noises, fluid leaks, and equipment conditions; quarterly tasks involve checking fan belt tension, lubricating blower bearings, inspecting air intake/exhaust screens, and cleaning/replacing filters; and annual tasks encompass inspecting painted surfaces, checking HVAC controls and safety devices, examining piping systems, verifying emergency equipment operability, and performing motor inspections. The document emphasizes that only trained, supervisor-authorized personnel should perform maintenance, and that maintenance frequency may be adjusted based on local conditions.
