Your air conditioning system has components that require internal lubrication (provided by periodic A/C system operation) to avoid drying out and cracking, which can lead to system leaks. Running your air conditioner regularly — even during winter months — helps lubricate these components and is recommended for many vehicles. However, some newer models eliminate the need for this. Midas recommends for many vehicles that you consult your owner's manual or visit our expert mechanics to get the right information for your vehicle.
