I sure hope it doesn't run on freon. That junk was banned years ago, but there's probably still some available on the black market. How would we find out what it actually uses, discover if it's low, and refill it?

No idea, but around here any A/C servicing is left to the professionals.

There probably is information and procedure for doing that, but it's most likely in the service manual for your particular A/C unit.

There are a few things that could be wrong, burned wires on the compressor, a locked up compressor, faulty circuit board, etc.

Again, it is throwing a code, decipher the code and that will tell you where to start the diagnosing ...

Freon is just a brand name !

What is in a/c units is refrigerant, there are many brands, and many refrigerants.

The Montreal Protocol called for the phasing out of certain refrigerants due to the alleged ozone hole issue.

The manufacturing of R-22 in the USA was banned in January 1, 2010, yet importation of it was/is still allowed.

Once the importation ban is mandated there will be only what is on the shelf and then the train wreck begins.

I used to do refrigeration work until a jug of R-12 went up to a thousand dollars .... I used to pay 25 dollars for a green jug, (R-22/aka Freon), today's prices ranges from 500 to 800 dollars for the same jug ! ! !
