Commercial HVAC AMCs (offices, hospitals, malls, factories) are won on price and kept on records. An HVAC maintenance checklist with readings for every visit proves the work and shows trends before a chiller trips in May. Download the CSV and adjust the equipment list per site. Follow each maker's maintenance instructions.
HVAC maintenance checklist: AHUs and FCUs
- Filters cleaned or replaced; pressure drop if measured
- Belts, pulleys and bearings; motor current
- Coils clean; condensate tray and drain clear
- Dampers and actuators working
Chillers
- Refrigerant suction and discharge pressures, temperatures
- Chilled water in and out temperature
- Oil level and pressure; alarm history
- Condenser tubes and approach temperature (as per schedule)
Cooling towers
- Fan, motor and gearbox; vibration
- Basin and fill clean; nozzles clear
- Water treatment and blowdown as per programme
VRF and ducted splits
- Outdoor units: coil, fan, error log
- Indoor units: filter, drain, louvres, remote and controller
Ducting and controls
- Duct leaks, insulation, grilles
- Thermostats and BMS points, if in scope
Frequency
Typical AMC splits are monthly (filters, drains, visual, readings), quarterly (coils, belts, electrical) and yearly (deep cleaning, condenser tubes). Agree them in the contract. For split ACs in homes, use the AC service procedure checklist.
Equipment, visits and readings in one record
ServicePilot keeps each site's equipment, creates AMC visits on schedule and stores the checklist and readings on each job. See AC service management software.
