My air conditioning is not getting cold or even cool. There are several types of R134a offered. One with oil, one with oil and leak detector, one with leak detector, and one that has nothing in it, it is just R134a. Which one should I recharge the system with.

    You will need to have your AC system evacuated with an airconditioning mechanic. Use regular R134 in your system, because when they evacuate the system they will also take some oil out of the system. Teh compressor oil is measured when they do this and they add the same amount back when they Recharge your AC system with R134.
    They evacuate the system, pull a vacume on the system and check for leaks by watching the gauge if the gauge goes down rapidly you have a bad leak somewhere in the system. You can waste alot of $$ if you just shoot R 134 without checking for leaks. AC Technicians Pay $120.00 for Large 30 LB bottle of R-134 refrigerant for automobiles.

    First check for leaks. Then fix leaks. If system only needs recharging, then just use R-134a refrigerant without the oil. I run ac summer & winter.
