Summer is winding down; nevertheless, you can still expect a few more weeks of hot weather. You will still need to rely on your AC for the time being. However, many motorists have complained that their car’s AC is blowing warm air. What’s going on with the AC system?
The AC’s refrigerant may need to be topped off. If the refrigerant level is low, then there is probably a leak. Without enough refrigerant, the AC begins blowing warm air. Unlike other leaks, this does not necessarily manifest in the form of oily puddles under the car. An auto repair technician will need to identify the more subtle signs, such as oil buildup around the AC hose.
The compressor has the all-important task of circulating the refrigerant and shuttling heat from the car’s interior. If the compressor doesn’t operate correctly, the refrigerant can’t do its job. Warm air out of the AC vent is one of the symptoms.
To prevent premature compressor wear, run the AC at least once a month during the off-season. Alternatively, you can simply run the defroster.
Faulty Electrical System
The car’s AC system is far more complex than the average motorist realizes. It has dozens of wires, fuses, and pressure and relay switches. Any of these components can malfunction at any moment due to old age. When this happens, the AC will automatically shut down to prevent further damage. In some instances, it will continue to operate but blow hot and stuffy air. An auto service will need to determine which specific component has worn out.
