AC readings-Help

Hello all,

Having some trouble. I tested my ac with it being 85-90 outside 10% humidity. At idle it reads 36 on the low and 250 on high. When we rev it to 2k the low drops to 19 and the high to 320. Is that normal?

It’s my wife’s car and it has recently started going from cold air to warm. Having difficulty recreating it on demand and trying to figure out if it goes warm at idle or when she is accelerating.

Thoughts on the numbers above tho? Thanks!!

After you rev it to 2000 rpm, once you turn off the car, how long does it take for the high and low pressure readings to equalize?.

I’d take it to a good a/c shop if it’s acting up.
