Summer's imminent arrival means your vehicle's air conditioning system is going to be under a serious strain before long. If you haven't had your system serviced in a while, now's the time. While most newer vehicles may simply be able to get away with having their A/C recharged, older cars and trucks may require a little extra attention. 

If you think your A/C isn't as frosty as it used to be, but it's still blowing cool air, the system just may need to be recharged. While you can technically recharge your vehicle's refrigerant yourself, its best left to a qualified professional with the proper equipment.
