Commercial HVAC System Seasonal Inspection Checklist [FREE PDF]

Commercial HVAC seasonal inspections are mandated under ASHRAE Standard 180-2012 (Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems) to ensure energy efficiency, indoor air quality, and equipment longevity. EPA Section 608 of the Clean Air Act imposes strict refrigerant handling and leak detection requirements on technicians servicing systems containing more than 50 lbs of refrigerant. Failure to comply with these standards can result in fines exceeding $44,539

  • Industry: Facility Management
  • Frequency: Quarterly
  • Estimated Time: 60-90 minutes
  • Role: Building Engineer
  • Total Items: 40
  • Compliance: ASHRAE Standard 180-2012 Section 5.2, EPA Clean Air Act Section 608 (40 CFR Part 82), OSHA 29 CFR 1910.147 (Lockout/Tagout), NFPA 70 NEC Article 440 (Air Conditioning Equipment), International Building Code Section 1502 (Mechanical Systems)

Lockout/Tagout & Pre-Inspection Safety

Verify all energy isolation procedures are followed before beginning mechanical inspection.

  • Has lockout/tagout (LOTO) been applied to all energy sources before beginning inspection?
  • Is personal protective equipment (PPE) appropriate for HVAC inspection confirmed and donned?
  • Has the equipment service history been reviewed prior to this inspection?
  • Are all access panels and service doors intact and lockable?
  • Has a confined space assessment been performed for any air handling units requiring entry?

Air Filters & Coil Inspection

Inspect and document condition of filtration systems and heat exchange coils.

  • Are all air filters inspected and replaced or cleaned per manufacturer specifications?
  • What is the current filter MERV rating installed?
  • Are evaporator and condenser coils free of dirt, debris, and biological growth?
  • Are coil fins straight and undamaged with no evidence of physical damage?
  • Please upload a photo of the filter condition and evaporator coil?

Refrigerant System & Leak Detection

Verify refrigerant charge, inspect for leaks, and confirm EPA compliance documentation.

  • Has a refrigerant leak check been performed on all accessible fittings and joints?
  • Is the refrigerant type and charge level documented and within manufacturer specifications?
  • Is the suction line temperature within the manufacturer's specified operating range?
  • Is refrigerant handling performed only by EPA Section 608-certified technicians?
  • Are all refrigerant cylinders stored properly and labeled with refrigerant type?

Electrical Components & Controls

Inspect electrical connections, controls, and safeties for compliance and safe operation.

  • Are all electrical connections tight, corrosion-free, and within rated ampacity?
  • Are all contactors, relays, and starters free of pitting, burning, or excessive wear?
  • Is the thermostat or building automation system (BAS) set point verified and calibrated?
  • Are all safety controls (high pressure, low pressure, freeze stats) tested and operational?
  • Is the disconnect switch properly rated and accessible with required working clearance?

Mechanical Components & Lubrication

Inspect belts, bearings, motors, and mechanical drive systems for wear and proper lubrication.

  • Are all belts inspected for wear, cracking, glazing, or improper tension?
  • Are all fan and motor bearings lubricated per manufacturer specifications?
  • Are supply and return fan blades free of debris buildup and physical damage?
  • Is measured motor amperage within 10% of nameplate full-load amps (FLA)?
  • Please enter the measured supply fan motor amperage?

Ductwork, Dampers & Airflow

Verify ductwork integrity, damper operation, and airflow balance across the system.

  • Is accessible ductwork free of visible damage, disconnections, or air leakage?
  • Are outdoor air, return air, and exhaust dampers operating freely and fully?
  • Are economizer dampers (if present) functioning and actuator controls operational?
  • Is measured supply air temperature within the design setpoint range?
  • Are VAV boxes or zone dampers (if applicable) inspected and responsive to controls?

Condensate Drainage & Pan Condition

Inspect condensate drain pans, drain lines, and secondary drains for blockages and biological growth.

  • Is the condensate drain pan free of standing water, algae, and debris?
  • Is the primary condensate drain line clear and flowing freely when tested?
  • Is the secondary (overflow) drain pan and drain line clear and unobstructed?
  • Is the condensate pump (if present) operational and float switch responsive?
  • Please upload a photo of the drain pan condition?

Documentation & Inspection Closeout

Complete all required documentation, identify deficiencies, and schedule corrective actions.

  • Have all deficiencies identified during this inspection been documented with corrective actions?
  • Have all refrigerant additions or recoveries been logged in the equipment service record?
  • Is the estimated time to next scheduled seasonal inspection documented?
  • Please provide any additional observations or recommendations for this unit?
  • What is the overall condition rating of this HVAC unit?
