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](https://servicepilot.in/blog/ac-service/ac-service-procedure-checklist/). ## Equipment, visits and readings in one record ServicePilot keeps each site's equipment, creates [AMC](https://servicepilot.in/features/amc-contracts/) visits on schedule and stores the checklist and readings on each [job](https://servicepilot.in/features/jobs-and-scheduling/).

Follow the maker and adjust for the site. **Q: Should readings be recorded?** A: Yes: pressures, temperatures and motor current. Trends show problems before breakdowns. **Q: Who should work on chillers?** A: Trained engineers following the maker's procedures; refrigerant handling as required by law. ## Related articles [AC & HVAC Service AC Installation Charges: Standard Price and Extras AC installation charges for AC service firms: standard split and window installation, copper pipe per foot, stands, drilling, extras and a worked price example.
