Maintenance Tips
-
Replace or clean air filters every 1–3 months to maintain proper airflow and prevent dust buildup on the coil.
-
Inspect and clean the evaporator coil annually to ensure efficient heat transfer and optimal cooling performance.
-
Keep the condensate drain pan and drain line clear to avoid water overflow, clogs, and mold growth.
-
Check refrigerant line connections (3/8" liquid, 7/8" suction) for leaks or damaged insulation.
-
Verify TXV (thermal expansion valve) operation for correct refrigerant flow and system efficiency.
-
Inspect coil cabinet and insulation to prevent air leaks and condensation issues.
-
Maintain a clean surrounding area to reduce dust and moisture accumulation near the unit.
-
Schedule annual professional HVAC maintenance to check coil condition, refrigerant charge, and overall system performance.
