Last week I took a long drive and noticed 45 minutes into my trip that Mist was coming out of my vents, after I smelled chemicals so I shut the ac off an found an automotive store and put in some refrigerant,Afterward I never smelled or seen the vapor again.I never changed my cabin filter(8 years) till today. I picked up a set of gauges to check both the high and low side.Compressor turns on for 9 seconds and turns off for 4 seconds.I found an Acura A/C chart for high-low and it seems like my numbers are off.Does anyone have a chart For CRV?

74 degrees(75 degree chart)

Humidity 80

Suggested reading

Low. High. Temp. Cabin

25-37. 84-155. 43 degrees output

Actual Reading

26-40. 150-170 43/46degrees

My low reading of 26 is compressor on and 40 is compressor off.For high it’s 170 compressor on(then drops) and 150 compressor off.

While the compressor is running the high hits 170 and starts dropping before the compressor shuts off.Is This normal?

Static reading
H—L

84 85
I’m going to clean the condenser with some coil cleaner.
Do I have a defective Drier packet?or expansion valve?or do these numbers look normal?
Thank you for helping me out!!!

 

Normal

You only check pressures while the compressor is running and after the temperatures in the system have stabilized.

The mist in the cabin is normal under certain weather conditions, mostly high humidity. It is the ice on the evaporator melting off.

 

I tested the system again after coil clean and taking a 1/2 hour drive.The Acura levels suggested ;76-85 degrees 80% humidity

So the Low side with the compressor engaged is 29PSI and the high side with compressor engaged and high settling is 195 @Idle .I’m not sure if Acura would be “Accurate” for CRV ..pun intended but the high side is slightly over the limits.Is this anything to worry about?

 

Idle will see higher than normal high side pressure with the limited air flow over the condenser.

If you are not having cooling issues (is suspect you are bot with those numbers) then send it.

 

The A/C seems fine now .I just want to make sure .
