Maintenance Tips

Clean indoor air filters monthly — Remove and rinse each zone’s filter with lukewarm water; let it dry completely before reinstalling.

Wipe indoor air handlers using a soft, damp cloth to prevent dust buildup that can affect airflow and cooling efficiency.

Inspect outdoor condenser coils every 3–6 months — Use a soft brush or low-pressure air to clear leaves, debris, or dirt.

Keep the condenser area clear — Maintain at least 24 inches of clearance on all sides to ensure proper airflow.

Check the condensate drain lines periodically for blockages or algae buildup; use a mild vinegar solution to flush if needed.

Inspect line set insulation annually to ensure it remains intact and sealed from UV damage or moisture intrusion.

Use the self-cleaning function (if enabled) on each air handler to reduce mold and odor buildup inside the unit.

Operate in “Fan Only” mode for a few minutes after cooling — helps dry out coils and prevent mold growth.

Monitor system performance via the MRCOOL SmartHVAC app to catch temperature irregularities or zone inefficiencies early.

Schedule an annual professional inspection to check refrigerant levels, electrical connections, and overall system health.

Check wall brackets and mounts periodically to ensure all indoor units are secure and vibration-free.

Avoid overloading one zone — distribute usage evenly to maintain consistent performance and extend compressor life.
