I have a 2012 Fit with 130k. Short trips around town and back and forth to work, the AC works OK. But on longer trips around an hour or so the AC stops cooling even with the fan on high and sometimes the fan output is barely there. All signs that the the evaporator is freezing up.

I purchased an AC thermometer and placed it in the center vent. On normal it would cool to about 42 degrees and on recirculate mode it would get down to 38 - 40 degrees. On long trips I would watch the thermometer and when it started creeping up, I would turn off the AC for a few minutes and then turn it back on. Happened much more frequently in the normal mode, so I would just leave in the recirculating mode.

Had another trip to Florida coming up with 95 degree temps to deal with so I tried the A/C ProŽ Ultra Synthetic R-134a A/C Recharge Kit.

On a 90 degree day, the gauge read around 45 PSI on the low side at idle and about 24 PSI at 2000 RPM. I added about 2 - 3 pounds. (About four 12 second trigger presses) So now around 48 PSI at idle and 26 PSI at 2000 RPM.

The AC worked great for the whole trip. On normal and 96 degrees the AC thermometer never got above 40 degrees and on recirculate mode would drop to about 37 degrees. A very comfortable trip for us.

 

Glad you got it going again. I had to do that with mine but it only lasted a month or two before it was back to its old ways.

Pounds or ounces??
In any rate, 3 OZ is 1/4th capacity of the system and can make a huge difference. On my car it's never goes below 50 degrees F on 2nd setting

 

The 2 - 3 pounds added was based on the stabilized reading on the AC Pro pressure gauge.

 

I've used ac pro and very useful. Golnat keep trying, that's only two refills a summer and you might get lucky ... My slow leak has miraculously solved itself as the car got older and I haven't added any in two years now!

 

I tried using AC pro with my Fit... but I manage overcharge my system... and killed my compressor.

I just googled a youtube video for AC Pro... I guess I misunderstood the instructions.

P.S. The compressor was probably going to die soon anyway, as it had been hissing every so often before my attempt. It just hissed a lot more afterwards.
