Change standard air filters every 1 to 3 months to prevent restricted airflow, reduce energy consumption, and avoid system overheating. Routine filter maintenance is essential for optimal HVAC performance and indoor air quality.

Wash indoor evaporator coils and outdoor condenser coils to remove dirt and debris, ensuring uninhibited heat transfer and system efficiency. Regular coil cleaning prevents capacity loss and reduces energy costs.

Clear debris, algae, and clogs from drain lines and pans to prevent water damage, mold growth, and high indoor humidity. Proper condensate management protects building infrastructure and occupant health.

Inspect wiring, tighten loose connections, and test run capacitors and contactors for signs of wear or pitting. Comprehensive electrical diagnostics prevent unexpected breakdowns and ensure safe operation.

Measure system pressures, evaluate subcooling and superheat values, and check for refrigerant leaks. Proper refrigerant management is critical for system efficiency, capacity, and compressor longevity.

Lubricate moving parts such as fan motors, inspect and replace worn belts, and calibrate thermostats. Regular mechanical adjustments reduce friction wear and extend equipment lifespan.
