Ok...so back in 2016 my AC was blowing quite cold.

Then around summer time I noticed it wasnt blowing AS cold but still cold. Come September-October, it wasnt cold anymore. Just whatever ambient temp outside.

I bought gauges, evacuated the system and did vacuum. Vacuum held so no apparent leaks.

I bought 2 refrigerant canisters and put into the system the proper amounts (like can and a half if I recall). Canisters also contained oil already.

This caused the AC to blow "cool" air. Not cold but cool. This was done in February 2017.

I left it like this because I had more pressing issues to take care of.

Yes, clutch engages. No blinking AC light. Servo Motors appear to be turning fully.

So heres the thing, a few weeks ago, suddenly its throwing cold air. I dont think its as cold as it should be but its cold now versus "cool" from before.

But it only lasts about 20-30 mins before it goes down. If I park for a while, then drive again, cold again for a bit then down.

I did readings on the L and H and this is what I found....

Car On, No AC
----------------
Low: 115
High: 120
Ambient Temp: 80-83 F

Car On, AC On
----------------
Low: 55
High: 180
Ambient Temp: 80-83 F

When I had initially vacuumed the system and refilled, with the Car On/No AC, I was reading ~100 on both Low and High.

Can someone help me out here!

Mines cools great, 2015 GSFS. My 2006 Honda cools to FREEZER levels , literally, but its the difference in refrigerant.

How many lbs. of refrigerant were removed from the system and was the same amount used to refill it after pulling vacuum on it?
