A mechanic reveals the most common air conditioning failure: "What's changed the most year after year is this little valve."

With the arrival of summer, it's important to keep your car in top condition. Vacations and high temperatures mean that the air conditioning becomes the most used and, therefore, the most important part of your car.

However, it's also true that breakdowns in this part of the vehicle become more common, whether due to constant and excessive use or, more precisely, due to disuse throughout the rest of the year. Therefore, a mechanic has explained the most common breakdown in this regard.

"What changes the most year after year is this small valve that controls the operation of the air conditioning compressor," explains the mechanic.

"I've told you many times not to change compressors so easily. This car came in because the compressor was diagnosed, and yet it was this valve. The cost difference between a compressor and the valve is huge," he points out.

Therefore, it's important to be careful before carrying out any repair. Not only does this mean saving money, but you also ensure that the vehicle's original part is maintained.
