Heating Ventilating and Air Conditioning

How often does the air conditioner require servicing on a Subaru outback with a 3.0 H6 engine?

The air conditioner is a closed loop system, and therefore requires little maintenance other than what your owners manual specifies. If you notice decreased performance (less cold coming out of the vents), It is time to take it to the Subaru dealer or an a/c specialist and have your air conditioning system recharged.
