Preventative maintenance focuses on scheduled, systematic activities to identify and address issues before they escalate into failures or inefficiencies. Comprehensive plans typically include:

​

• Regular System Inspections — Thorough visual and performance checks of components like compressors, fans, belts, motors, and electrical connections to detect wear, misalignment, or early degradation.

​​

• Cleaning and Coil Maintenance — Professional cleaning of evaporator and condenser coils to remove dirt, debris, and buildup that reduces heat transfer efficiency and increases energy consumption.

​​

• Filter Replacement and Airflow Optimization — Timely replacement of air filters and verification of proper airflow to maintain indoor air quality and prevent strain on system components.

​​

• Refrigerant Level and Leak Checks — Monitoring refrigerant charges, pressure testing circuits, and inspecting for leaks to preserve cooling capacity and avoid efficiency losses.

​​

• Lubrication and Mechanical Adjustments — Lubricating moving parts and tightening connections to reduce friction, vibration, and premature failure.

​​

• Controls and Electrical Testing — Calibrating thermostats, sensors, and building management systems (BMS) while testing electrical safety and performance.

​​

• Performance Verification — Measuring key metrics such as temperature differentials, amperage draw, and overall system output to confirm operation within manufacturer specifications.
