About a year and a half ago my wife bought a new ac compressor and had it installed by a shop, without talking to me first. The air only lasted about 6 months and needed to be recharged again. After the recharge it did not blow cold, rather only cool air and only lasted about two weeks. I am pretty sure they only replaced the compressor and do not think they evacuated or did a vacuum(not sure if the two are different?).I am getting ready to put in another compressor, dryer and orifice tube.
Question is, is there any way to test the existing system, just incase the compressor is still good, to see what might actually be wrong, before i install a new compressor?
Should you have to replace the seals on a new compressor, before install?
How do you do an evacuation of the system?
Can I use a hand vac pump, like the myti vac pump, or does it have to be electric?
Are there any tech wright up on an Ac system?
Thanks for any help.....
