How can I determine if the ac is removing the correct amount of moisture from the air?

Hi Antonio you can buy a top up can in place that sells parts. Simply attach the fitting on the can to the air con line with the engine running and the air on on full some cans have a gauge on them so you will know when it's charged. If the system has been opened and needs s fill you will need to go to a workshop or an aircon specialist. The system will need to be vacuumed to remove air from the pipes to prevent hot spots and then filled. Regards Jkm...

I have a 2000 GMC Savana Van SLT with front and rear AC/Heat. My front would blow hot while the rear blew cold with AC on. It turned out to be low on Freon. It's hard to know if you have the right amount of freon installed because pressures vary depending on the ambient temperatures. So the best way is to remove all the freon then reinstall the recommended amount as listed on the evaporator housing near the firewall. This worked fine for me... works like new after installing the correct amount of freon.

Between 8 and 12 oz. would be the normal amount found in an AC compressor. Polymax2 auto A/C refrigerant oil is a good choice.
Polymax2 Refrigerant oil is unique. Not only does this oil provide other benefits to your vehicle's A/C system, it's even non-hygroscopic. That means it will NOTabsorb moisture. In fact, Polymax2 is formulated to repel moisture!

IT may be getting the correct amount of air but getting excessive fuel for starting . So check the air / fuel sensors .

The dehumidifier needs to have the control set correctly and the fan and the compressor to run in order to remove moisture from the air. The fan pulls the warm, moist air over a cold coil where the moisture condenses into water. Cool, dry air is expelled from one side and warm dry air from the other.
If the unit is low on refrigereant, the compressor will not run - nor remove moisture. Likewise, the control must be set right, too. Finally, most unit rely on a float switch or a tank switch to determine if the tank is full or present. If the float switch or tank switch is jammed due to tank position, it may prevent the unit from running. Remove & carefully reinstall the tank to see it that solves the problem.
Good luck!

Have the system pressures tested with a set of AC pressure gauges at a local shop to determine whether the system is low on refrigerant. If the system is found to be low the leak must be repaired, the system evaluated with a special vacuum pump and then refilled with the correct amount of R134 refrigerant.

you have air in the system or a small amount of moisture in the system, you need to evacuate the system by recoveringthe refrigerant and put the system into a vacumn to remove the moisture, then you needto recharge the system with the correct amount of refrigerant.

NOTE: Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.
NOTE: If an A/C condenser core leak is suspected, the A/C condenser core must be leak tested before it is removed from the vehicle. For additional information, refer toSection 412-00.

1. Recover the refrigerant. For additional information, refer toSection 412-00.

1. Remove the front bumper cover. For additional information, refer toSection 501-19.

1. CAUTION: Plug all ports to prevent contamination from dirt or moisture.
   Remove the nuts from the two condenser core air conditioning line (peanut) fittings.

1. Remove the screws and the A/C condenser core brackets.

1. NOTE: When removing the A/C condenser core, disconnect the two air conditioning line (peanut) fittings from the A/C condenser core.
   Remove the A/C condenser core.

1. To install, reverse the removal procedure.
   • Lubricate the new A/C condenser core with the correct amount of PAG Compressor Oil YN-12-C or equivalent meeting Ford specification WSH-M1C231-B. For additional information, refer toSection 412-00.
   • Lubricate the O-ring seals with PAG Compressor Oil YN-12-C or equivalent meeting Ford specification WSH-M1C231-B.

That's an interesting question and I'm assuming you're asking it from a point of view of 'is there enough gas in the unit for it to operate correctly?'

Most all (if not all) window units are 'sealed' units, and you cannot check the amount of gas in them.

That being said - it's possible that the AC unit you're talking about - has (in the past) been 'opened up,' and therefore - it will have valves installed in it.

By putting Air Conditioning gauges on the unit one can determine (by pressure readings) if there is/or isn't enough gas in the unit for it to operate correctly.

If your question is to be taken literally- then it's entirely possible to remove the gas from a unit (if it has valves) and weigh the gas to determine how many ounces/pounds of refrigerant is there - but not practical in any sense of the word.

thanks for an interesting question
