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.
