Air Conditioning Services consist of any service performed on the equipment that delivers cool air to the cabin of your car. The major components of your air conditioning system include the compressor, condenser, evaporator, expansion valve, and refrigerant. There are a variety of problems that can hinder your air conditioner’s ability to generate cold air—it may be as simple as needing to add refrigerant. However, normal wear and tear causes seals, hoses, and fittings to get loose and wear out. When this happens, refrigerant can leak out.
