Indoor unit maintenance requires meticulous attention to multiple components affecting both performance and air quality. We begin with thorough filter inspection and cleaning or replacement, as dirty filters cause most mini-split problems. The evaporator coil receives careful cleaning to restore heat transfer efficiency.
Outdoor units endure harsh weather conditions requiring robust maintenance procedures. Condenser coils accumulate dirt, leaves, and debris that drastically reduce cooling capacity. Our maintenance includes thorough coil cleaning using appropriate chemicals and techniques, fin straightening to restore proper airflow.
Refrigerant system checks ensure optimal performance and identify developing leaks early. We measure superheat and subcooling values, verify refrigerant charge using manufacturer specifications, check for signs of refrigerant or oil leaks, and test expansion valve operation.
Electrical component inspection prevents failures and potential safety hazards. We test and tighten all electrical connections, measure capacitor values and replace if weakening, verify contactor operation and contact condition, and inspect wiring for damage or deterioration.
