Air conditioning port location?

[Eric Braun]

I have a 1987 252 TSE and am trying to locate the factory high and low pressure ports to service the freon. Does anyone know where they are? I only see the ports on top of the compressor. Thanks

Wow you have one of one or two 252s with air conditioning.  Would the ports be in the avionics bay back near the battery in the tail, where they are on later Mooneys?

On the Ovation the A/C service ports are located in the avionics bay, top left just above the removable panel.

Those may be valves and not ports, if there is a thin cover remove that and under the cover there is usually a valve stem. If you have any trouble with the system taking refrigerant check those valves especially if you are working on an inop system that was inop when you bought the aircraft and or the compressor has been replaced.
