Tech answer is:3 pints of water per hour per 1 ton of cooling.
General rule of thumb is 20-25% of the capacity of the unit is devoted to dehumidifying.
If unit runs constantly and the temp really does not seem to be effected, unit is probably too small. If unit runs and cycles off frequently, i.e. short run times, and humidity is high, unit is too big.

Hope this helps

How to recharge the ac


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...

How much freon an oil does this system take


the amount of oil in an ac system is determined in the compressor and unless there has been a major leak where the oil is lost then no oil will be needed . As to the gas, it is added until the correct pressure during operation is obtained. It will be far cheaper to have the system checked for leaks and the correct amount of gas added by an accredited ac specialist shop.

My gmc yukon 2000 slt rear ac blows hot air when i have ac . on and the front works fine .


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.

Dehumidifyer not dehumidifying


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!

Air conditiong not working


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.

AC is measuring full on the low side - 35 psi - and compressor is cycling, but the air is still not really cold in the cab. My gauge will not measure the high side. I believe actuator and switch are fine....


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.

How to check the quantum of gas filled in window airconditioner


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
