It should be listed on the tag on the outdoor unit (in ounces). If not I would say between 8-12 lbs as a guesstimate.
depemds on the car as how much freon it will hold. some cars have a tag saying how much freon the car is filled with. Too much freon is just as bad as not enough freon.
Answering "Where do you add freon to your air conditioner in your ford ranger?"
== ==
This is not an answerable question. The correct amount of freon is set during the initial set up by the installer and is dependent on the length and routing of the lines.
$100
29 dollars for refill
you use freon to cool your car and make the air conditioner work
A 1990 Cadillac Deville air conditioner should hold 46 oz. R12 Freon. This should be verified through the owners vehicle manual.
it depends on the size of the system, this info is usually on the name tag, where you'll also find model and serial numbers.
Is it feasible and approximately how much will it cost to replace the air conditioner in my '91 Miata with a unit that does not use freon?
That sounds reasonable to me. I have in my home, a very large (22,000 BTU) through-the-wall air conditioner, designed to cool three large rooms. It uses 3.5 lbs of freon. A whole-house unit I can easily see using as much as 9 lbs.
you need 8.00 oz. of oil and 2.25 lbs of freon
