I have 1992 Cadillac Deville. Recently had old Freon removed

Customer Question

I have 1992 Cadillac Deville. Recently had old Freon removed and all new Freon (34a) put in and computer adjustments made. A/C was working perfect and 1.5 hours into a trip on very hot and humid day, 'A/C Requires Maintenance' light went on and A/C started pushing out hot air only. Shut it down and parked it. Next day, when doing local driving I felt cold air coming from foot area and realized I had not shut A/C off completely. Turned A/C to 'High' and it has been working ok since. Concerned that it will stop working again. Any idea what could have caused problem and how to make sure it doesn't happen again ? This is going to be our Florida winter car and need A/C to be VERY dependable.

The 'shop' was my son-in-law who did it in his garage, so I have no receipt. What are they to 'check' if it iced up and defrosted ?
Expert:  roybelding replied 4 months ago.

if he has a set of gauges, he can monitor the pressures especially when it runs for a while. the low side should never go below 20 lbs.

how much freon did he put in the system. if he put too much or little, it will cause this

Now that I know where the problem generally lies, I will take it to a Caddy dealer and have it taken care of. I have an appointment set up for tomorrow am. I was concerned it could be something worse like the compressor. Thanks for the help.
