A Refrigerant Leak
The discomfort you experience comes from leaking refrigerant vapours. One simple sign of a refrigerant leak is the refrigerant stains and bubbles near connections. These classic signs indicate a refrigerant leak and, if left unnoticed, may cause irreparable damage to your heavy-duty systems. Hissing noises may also represent refrigerant leaks. Odd noises from your trucks can mean various issues, but if it specifically hisses, then more times than not, it is a refrigerant leak.
One of the earliest signs of compressor failure is valve malfunction. The expansion valve controls refrigerant flow into the compressor, and a malfunction means you lose control over your A/C. When you get shivers and turn off the A/C, a broken valve continues to feed refrigerant and release cold air into your passenger seat. Over time, constant refrigerant feeding will put your compressor out of commission.
Recognizing the Red Flags of Compressor Failure
Inconsistent Temperatures: Do you feel you are getting hot and cold flashes in the passenger seat?
Poor A/C Performance: Do you have your A/C cranked up to max but still sweating bullets? The compressor may be worn out and damaged.
Unusual Noises: You know your truck. You know what it sounds like. Clanging is not part of its regular playlist. If you hear persistent clanging noises, that could be a symptom of compressor failure.
Frozen Coils: Frozen coils can block airflow and cause a moisture buildup. A frozen coil usually occurs due to broken fans or dirty air filters.
