I know that there are different levels of doing things...the correct professional way, the amature way that is sometimes not the best and the absolute wrong way. Hypothetically speaking if a system did not get evacuated properly and was charged with R134a (did not use correct vacuum pump capable of boiling off the moisture); however POE BVA Auto 100 oil was used that does not attract moisture and an new accumulator (fresh disicant to absorb moisture) how detrimental to the system would this be ? I know it is not IDEAL but would it sufice or is it a matter of time before the system fails ! Just trying to learn the ins and outs, anybody have any thoughts I would love to hear them. Thanks.
I would say that it depends on the amount of moisture thats in the air. Might be able to get away with it in Vegas, Probly not in Lousianna.
Also remove any air in the system when pulling a vacuum on a system. Air in the system can cause all sorts of cooling issues.
Not evacuating the system is definitly the wrong way to do it. Can understand if you don't want to buy all the charging equipment to do just one car... might see if your auto parts store rents out a vacuum pump. Otherwise, it might be best to take it to a shop after the system is cleaned and assembled, have them evac and charge.

mhamilton thanks....I will look into renting an electric vacuum pump. I was just seeing if one can "get by" with vacuuming a system at lower pressure and not boiling off all the moisture. I was seeing if it was possible to get by and not cause future problems if the POE BVA Auto 100 oil and new accumulator was used; that whatever moisture was left in the system possibly would just get absorbed by the accumulator. Seem clear that this is not the case and defineately need to pull a decent vaccum to make sure all the moisture is boiled off. Thanks.
