If you live in a hot climate, having ice cold air conditioning in your vehicle is essential during the summer months. Unfortunately, auto A/Cs can wear out and malfunction over time and need to be repaired. Some common signs that it is time to take your vehicle to an auto shop for A/C service include:

Lack of Refrigerant

Just like a residential air conditioning unit, a car A/C utilizes refrigerant to remove heat from the air and rapidly chill it. Over time, the level of refrigerant can diminish and when the level falls low enough your car's air conditioner will no longer be able to produce cold air. Luckily, having your car's air conditioner charged and replacing the lost refrigerant can fix the problem. Keep an eye on the refrigerant reservoir and take your vehicle to a mechanic when the refrigerant level gets low.

Dirty Condenser Lines

In order for your car's air conditioner to operate properly, the condenser lines need to be clear so that air can flow in and be chilled. In the event that the A/Cs condenser lines get clogged with dirt or debris, their will be diminished air pressure and the air that does come through the vents will be lukewarm. A qualified auto repair shop will be able to clean and clear blocked condenser lines so you can enjoy cold air while driving.

Leaks

Like all auto parts, the components of an automobile's air conditioning system do not last forever. If the hoses, pipes, or valves in the air conditioning system tear or crack, their will be air leaks and the air conditioning unit will not be able to maintain the proper pressure to work as it should. When their are air leaks in the air conditioning system, you air conditioner will most likely stop working all together. Replacing the cracked or torn part is usually all that is needed to make your A/C operational again.

Mold or Mildew Growth

When a car is parked for an extended period of time, it is possible for mold and mildew to grow in the air conditioning lines, especially in a wet or humid climate. When this happens, it can cause a lot of problems for the air conditioner and you may notice that it is not running as efficiently as it used to. In addition, breathing in mildew and mold spores is generally not good for your health. If your air conditioner smells musty when you turn it on, have it checked for mold and mildew.
