One of the first things to do in the Summer is to ensure your vehicle's air conditioning system is working properly. Even a small leak can rob you of comfort and gas mileage. Running your air conditioner without sufficient refrigerant can overwork your compressor and cause expensive repairs needlessly. Save money now while enjoying the comfort of a properly cooled ride. Often, the only thing required to put your system back in top condition is simply a small amount of refrigerant.
