After changing the AC condensor can you recharge system with a do it yourself hose and can of 134 freon you bye at autozone. Or does it have to be done with special machine at a shop.

To do it right you'd need 200 dollars in equipment or pay a shop 120 too do it for you.. unless you plan to do other cars or be a mechanic then go too a shop

You can do it but you need special gauges, a vacuum pump, and a scale to measure the amount of 134 freon you put in. Autozone does rent gauges and a vacuum pump.

Yes, but it would be much better if you'd use the machine, that way you save what ever freon is in your system.
