Losing A/C Air volume

[pegt10]

Ford 97 XLT

A friend of mine put some freon in my system, gauges meet range specs. I noticed the air is not as cold and air volume out of vents drops once in awhile when I accelerate. A friend told me that I may be losing vacuum from canister or check valve is bad. Can someone help me in finding this solution or location of check valve. I looked under hood, but could not find a plastic valve, that resembles a check valve, but than again I'm not a tech.

Also what might be reasons for the air not be cold enough even when gauges read ok, according to my friend who helped me. I would like to buy gauges and do it myself. I beleive I can do it. Is there a thread in how to do this...Appreciate any help

Thx

Assuming that things are as you say.........gauge reading within spec........but, just not cold enough.

Perhaps, you and I have a probelm w/ vent doors? See my sad story:

The tech said the A/c "system" was working.........said "problem" was somewhere else.

Possibly........the heater air is mixing w/ A/C air, cause a vent door isn't working correctly. Or, the air isn't moving across the A/c evaporator cause a door somewhere (possibly at firewall) isn't opening when it should.

Or your charge could be too high. (eg. too much refrigerant). If you above in the "stickies" there is a ton of info on AC and how to recharge it etc.
