Re: Suburban A/C fix + Vintage Air?

It kills me a little that Hatzie sent that message while I was charging the beast and did not see it until after!

Boys and girls, here's the report.

65 degrees ambient air temp.
3:45pm
Front Vent temp: 82
Rear: 80
added one can of refrigerant (12oz). At some point during this HOUR I actually read the directions and shook the can, did the 12 to 3 tilt. This speeds things up.

The fans kicked on when they should, the compressor kicked on, everything was looking good. No blown fuses or craziness.

So far so good.



4:32pm
Front Vent temp: 88
Rear: 81 (we closed the windows!)

Added second can. 11.9 oz

4:50pm
Front Vent temp: 64
Rear: 68

Can no. 3 12.05 oz

5:38pm
Front Vent temp: 50
Rear: 52

Now we are cooking with gas!

As a test I put the thermometer in my CAR: 44 degrees coming out of the dash. This was now what I was shooting for.

At this point I slowed down (It was already slow) and measured 1-2 oz at a time, waited 5-10 minutes and compared the vent temps.

As soon as the temp started to stabilize (could not get it to drop further) I stopped.
Temp from the dash was 48 degrees in the front and 49 rear.

Should I be happy with those numbers?

Figure out the way to measure these that makes sens for you!



Honey, Have you seen the kitchen scale?



This was the lowest temp I got out of the front.
