Most likely a leak some where in your system and all that nice freon, or whatever the modern version is called, has escaped.

Did the regasser check for leaks first?

Well I don't know then. I assume you had the temp dial turned down enough for the system to work?:lol:

But I'd turn it off until its checked out. Just in case it is out of gas, some systems need the gas for lubrication.

Probably leaking from condensor, behind the fan. I presume he added a leak/tracer dye when it was regased?

Also check to see if the compressor is engaging. You can see it engage by getting someone to switch the aircon on and off whilst looking at the compressor to see if it starts spinning.

If it doesn't spin, there is a sensor on the side of the drier that stops the compressor from running if it senses that the gas level is too low.

Also the pipe feeding the condenser should be hot and the one going to the drier from the condenser should be cold.
