If one fact of life is certain, things age - and time is the enemy when it comes to your car's air conditioning system as well. Small (or big) leaks can start to reduce the effectiveness of your vehicle's A/C, affecting the ability for the compressor to receive adequate pressure to do its job.

The compressor's job is to make sure refrigerant is pumping at a high pressure on its way into the condenser, where the process of changing gas to a liquid occurs, followed by the liquid returning to a gas before it reaches your air vents. If something along the way isn't functioning properly, you may experience some warning signs:

• Less cool air from your A/C (it may still be cold, just not as cold as it used to be)

• Air flow is not increasing regardless of how high you turn it up

• Grinding or squealing sounds when the A/C is running could be sign of compressor issues

• Musty or stale smell coming from air vents may be a symptom of a coolant system leak or even mold growth

• Water leaking inside your car can be caused by blockages in the evaporator's drain tube

• Visible, greasy-looking leaks may indicate a Freon leak from the refrigerator (this can be a serious problem and requires immediate attention)

• Save (and avoid) repairs down the road - With routine maintenance of your car's A/C, you minimize the possibility of needing to resolve more complicated issues in the future.

• Health safety for you and your passengers - Regularly cleaning your evaporator keeps your air free of mold or mildew, which can create harmful breathing air or even unwanted allergies.

• Improve car's running efficiency - A healthy air conditioning system makes for a healthy vehicle that will use the optimal amount of oil and refrigerant, leading to less fuel consumption and overall increased functionality of the system.

• Assist with defrosting windshields - On those cooler mornings, when your car's windows fog up while driving, it's a healthy, leak-free air conditioning system leading the charge against that frost and fog.

The frequency at which you need to recharge your car's air conditioning system depends on many factors. In most cases, you just need to recharge your air conditioning when you notice a change in performance. Maintaining your car's air conditioning as needed will help stave off any major repairs. Regular car care will help you avoid air conditioning problems.
