Maintenance Tips

• Clean or Replace Filters Monthly: Dirty filters restrict airflow, reducing efficiency and increasing energy consumption. Clean or replace them every 1–3 months, especially during peak usage periods.

• Inspect and Clean Coils Semi-Annually: Dust and debris on the evaporator and condenser coils can hinder heat exchange. Use a soft brush or a vacuum with a brush attachment to remove buildup. Avoid harsh chemicals to prevent damage.

• Check Refrigerant Levels Annually: Low refrigerant levels can decrease cooling efficiency and damage the compressor. Have a professional technician check and top up refrigerant as needed.

• Inspect and Clean the Condensate Drain Line Quarterly: A clogged drain line can lead to water damage and mold growth. Use a mixture of vinegar and water or a specialized cleaner to clear any blockages.

• Keep the Outdoor Unit Clean: Remove leaves, dirt, and debris from around the outdoor unit to ensure proper airflow. Use a garden hose with a gentle spray to clean the coils, being careful not to bend the fins.

• Schedule Annual Professional Maintenance: A qualified HVAC technician can perform a thorough inspection, clean all components, check refrigerant levels, and perform any necessary repairs.
