Why Your AC Isn't Cooling: Troubleshooting Guide

When the sun beats down in Kanchipuram, a malfunctioning AC blowing warm air is a major discomfort. Before panic sets in, check these five common reasons why your air conditioner might not be cooling: 1. Clogged Air Filters If the filters are covered in dust, the airflow is choked. The evaporator coil freezes over, blocking cold air delivery. Clean the filter first! 2. Incorrect Remote Settings Ensure the AC is set to 'Cool' mode and the fan speed is set appropriately. Sometimes, accidental buttons put the AC in 'Dry' or 'Fan' mode, which doesn't turn on the compressor. 3. Dirty Outdoor Condenser Unit If the condenser unit is covered in dirt or blocked by clutter, it cannot release heat. The compressor overheats and shuts off via the thermal overload protector. 4. Defective Capacitor or Fan Motor The capacitor starts the compressor and the outdoor fan. If the capacitor blows due to voltage fluctuations, the compressor won't run, leaving the unit blowing plain air. 5. Refrigerant Gas Depletion A gas leak in the copper tubing will gradually reduce cooling capacity, eventually leading to zero cooling. Look for ice formation on the thin outdoor copper pipes.
