This must be a 15 passenger van or a Limo maybe. Keep adding cans till 35 psi on the low side or the fan belt starts squealing. if the belt is squealing that is an indicator you have a bit too much in there.

Is compressor running. If the fan runs and the compressor runs. You are out of refrigerant or the compressor has bad valves. Please leave feedback. Rusty

Make sure the unit is tilted slightly downwards in the rear so that gravity will make the water flow outside.

Time to put away your stick, lol you really need some help from someone that can replace if necessary the fan motor on the outside coil.
without that the system will not produce subcooled liquid and no latent heat can be displaced.

it could be a burnt out solenoid making a hole of its stem causing gas with oil to escape that is the white stuff

I just purchased a 11,000 BTU Everstar from Home Depot. Not sure if it's the same model that you have. Maybe check there? I bet an employee would be willing to open one of the boxes to answer your question. Just tell them you bought it there. :) Or call Everstar, of course. Good luck!

Freon is low. Sounds counter-intuitive, but the large return line should be cool( even have condensation on it) but never cold enough to freeze.Either use factory pressure settings or add just enough Freon until Ice melts. If unit has a high-side sight glass there should be no bubbles present. Do not overfill.

Unit should be tested, You have a "ground fault" condition.

It depends on what you think is costly. It could be anything from a capacitor to needing more refrigerant to your overload/relay on the compressor to needing a new compressor. These possobilities are writting in order off less expensive to more. It would be wise to rule out the things you can check yourself and then have a professional come and check it out.

Connect to the bottle and then connect to the low side (blue usually) to the low side service valve. You want the bottle to be warm. If its not warm it will be harder to charge. Don't heat the bottle just put it in the sun or put hot towels around it.

it could be abad thermostat or wiring problem

you will have to recxlaim the refrigerant from the uint due to the fact that the oils for the two don't mix

check the a/c unit. make sure you dont have any leaks around your system. sometimes when you have a small leak it will take time to lose out of system. but you may need to charge your unit up again. Also your compressor may be out of service. check and make sure compressor is running

If you have never done this before or have limited experience, let a qualified tech do it for you. It's worth the money and safety. If you have a set of gages and some experience, let me know and we can contunue. It's not too hard but some what dangerous. Think about it.
