A comprehensive AC service check-list includes cleaning or replacing air filters (monthly), cleaning evaporator and condenser coils, clearing the condensate drain line, and inspecting electrical connections/components. Essential steps also involve checking refrigerant levels, lubricating moving parts, checking thermostat settings, and cleaning the blower motor
- Air Filters: Clean or replace every 2–4 weeks, or as needed, to ensure proper airflow.
- Coils (Evaporator & Condenser): Clean coils to remove dust and debris for better heat transfer.
- Condensate Drain: Flush the drain line to prevent clogs, mold, and water damage.
- Electrical Inspection: Inspect capacitors, contactors, and wiring for signs of damage, wear, or loose connections.
- Refrigerant Levels: Check for leaks and ensure proper levels to maintain cooling efficiency.
- Fan & Motor: Inspect the blower motor for debris and ensure fans are functioning properly.
- Thermostat: Calibrate and verify settings for proper operation.
- Exterior Unit: Clear debris (leaves, dirt) from around the outdoor condenser and ensure it is on a level surface

Signs of Needed Maintenance
- Weak Airflow/Warm Air: Indicates issues with the compressor or low refrigerant.
- Strange Noises: Rattling, buzzing, or banging suggests loose or failing parts.
- Water Leaks: A sign of a blocked drain line.
- Short Cycling: The unit turns on and off frequently, causing strain
