Your AC system needs to be recharged with a can of R134A

I agree with brotherben. And if it needs to be recharged that means it needs other repairs. It's a sealed system so if refrigerant is needed that means it has leaked out somewhere. That is a job for professionals with the proper equipment and experience. Don't waste money on recharge kits. Just take it to a shop.

The high and low pressure sides of the system aka freon are good. It is full, never lost pressure. Thank you though.

Then possibly a compressor that's not working or the mechanism in the duct work that directs cold air instead of hot air through the venting is not working.
