One maintenance items car and truck owners may think they are safe in ignoring going into winter is the air conditioner.
After all, no one uses the air conditioner in the winter. Or do they?
The air conditioner in most cars and trucks operates when the defroster runs. That means the refrigerant pressure in the air conditioner should be at the proper level even in winter.
According to the service department at Putnam Chevrolet, the air conditioner is supposed to help reduce moisture inside the passenger compartment, which assists in defogging the windows.
If the refrigerant level is too low, the compressor will probably not operate. While this may not damage the air conditioning system, it certainly will prevent it from operating at peak efficiency.
