Maintenance Tips
-
Clean washable air filters every 2–4 weeks – Maintains strong airflow (up to ~847 CFM) and energy efficiency (21 SEER2)
-
Run self-clean function regularly – Built-in mode helps prevent mold, odors, and bacteria buildup inside the unit
-
Keep indoor & outdoor units debris-free – Ensure unrestricted airflow for optimal cooling/heating in 750–1000 sq ft spaces
-
Inspect and clear drain line – Dual drainage ports require routine checks to prevent leaks and water damage
-
Maintain proper outdoor clearance (2–3 ft) – Supports efficient heat exchange and inverter performance
-
Check refrigerant lines annually – Pre-charged R454B system should remain leak-free for peak performance
-
Use ECO & Sleep modes frequently – Reduces wear on inverter compressor and lowers energy consumption
-
Schedule yearly professional servicing – Ensures long-term reliability and optimal heating/cooling output
