I found a similar site for autos - it's www.alldatadiy.com It costs $25 /
year for service, but well worth it for complicated tasks like this one. It
has good step-by-step instructions and lots of diagrams. I think it's the
same thing as most garages use. I've got most of the dash out - spent two
hours today working on it. I't not too bad, yet!

I hold a universal and auto certification and found the site to be a good
basic site for the beginner. However, each manufacturer does have different
charge rates for their system. It is best to by one of the tech manuals
just for AC and they are pretty helpful. Check for leaks by putting about 20
lbs of nitrogen in the system and see if you get a pressure drop and be sure
to use a gauge that is in 1/4 lb increments. I have access to an ultrasonic
leak detector which will find a microscopic leak even under vacuum.

If there are no leaks it is time to evacuate the system which is the most
important part. There are several places that do rent vacuum pumps to
evacuate AC systems is cheaper to rent for a bout $75.00 a day than to spend
several hundred $$. If you put your system pack together and it is tight
then it should take about 2 hours to pump down the system to about 500
microns. Leave the system under vacuum and put in the proper type and amount
of compressor oil.

Once that is done you are ready to complete an initial charge IAW MFGS
instructions and tweak as needed to have at least 50 degree discharge air
from the vents. Also, there is an old tech trick by placing a fan in front
of your grill blowing across the condenser this will aid in system charging.
