Kia Spectra air conditioner blowing warm air despite refrigerant refill on Kia Spectra

Some Kia Spectra owners report experiencing issues with their air conditioning systems blowing warm air even after a refrigerant refill. This problem may be due to a faulty compressor that fails to circulate the refrigerant properly, resulting in warm air from the vents. Additionally, some owners have encountered refrigerant overcharge situations, where high side pressures trigger the high-pressure switch to shut off the compressor clutch, causing the air to turn warm after initially being cold. Refrigerant leaks are another common issue, leading to decreased refrigerant levels and warm air output. Furthermore, blend door problems may also contribute to the warm air issue. To resolve these concerns, it is recommended that owners seek professional diagnosis to check the compressor, refrigerant levels, and blend door functionality, as regular maintenance and timely repairs are essential for optimal AC performance.
