    a/c question

    So my original condensor went to hell the other day and started pissin out freon and compressor oil out every where. Got a new condensor and my question is; is there any way to get the air out of the system without putting a vaccum on it? Or can i just charge the sytem and not worry about air pockets being in it?

    Nope, you need to pump it down. The primary purpose of evacuating the A/C system is to remove moisture. If you have air in your system, you will also have moisture. Moisture can cause your expansion valve to freeze, and then your A/C no workie. Don't cheap out - have your system properly charged. You will appreciate it on those hot/humid SC days.

    It would be cool if there were some gas developed that you could pressurize the system with that would grab all the moisture molecule in the a/c and drag them out the schraeder valve when you bled the gas back out. It would be so nice to not have to pull a vacuum before charging then a/c's would be owner servicable without buying or borrowing a vacuum pump from Vatozone.

    They don't necessarily want HVAC systems to be user serviceable friendly. It would dramatically increase the amount of freon vented to the atmosphere.

    You know what I meant. Refrigerant. Freon has become a generic term like Coke.

    Good suggestion, it actually has a dry pack in the canister that removes moisture from the system.
