Before you had recharged your unit has the condition of the compressor analysed ? what is the condition of the condenser coils and the coiling coils.? Did you clean the filters? was the correct gas used for charging? Now go back to acess the fault that could have resulted in poor cooling. Dripping is indication of good cooling/ heat exchange , maybe this unit is working bettter. Since I am not aware of the age of the units, it becomes difficult to comment.
However please check with a clamp tester for the compressor motor current intake, failure of capacitor for low speed. blowing of fans, clean and check. Hope my advice helps you to recheck. Good day

Isn't blowing cold air, clened coils, removed, dirt, leaves, but still no cold air. Seems to be low on Freon. How do I get the unit charged?

The compressor needs to run, does it run? If it runs and the outdoor radiator is not producing heat, then it may be low on refrigerant. The compressor refrigerant lines, the skinny gets hot and the thick line gets cold under normal operation.
To recharge the unit, it needs to be leak checked and repair any leaks found, then recharged. The refrigerant type used needs to be known, a manifold gage set is used to diagnose and recharge.
If you have a window unit, you should have it serviced or replaced.

How do i get my soleus air conding unit to blow cold air, its blowing cool air. can i recharge this unit myself -if so then what type of freon would i use.

most likely have to install a line tap valve to charge. look for oil residue on lines to indicate leak. the evaporator is the weak point on most a/c systems.

My dehumidier blows very hot air while working. Makes it hotter than it was before starting. Like a furnace.

It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in.
You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.

Can a fedders air conditioner A7Y15F2A-E be recharged?

Hello, anytime the unit does not blow out cool air I like to start with checking the airflow, check the filter and the evaporator coil for a buildup of dirt. If that check out ok then either the unit has a refrigerant leak or the compressor is not operating if the compressor is running than the unit is low on refrigersnt and can be recharged. In order to recharge the unit a piercing valve must be installed on the low side of the system, most window units do not have valves so one must be added to be able to charge the unit.

My amana window ac is blowing condesation out the vents. it is still this a problem

There is a condensation drain on the unit that is probably plugged. It is natural for air conditioning units to produce condensation as the evaporator coil (the coil/fins that make the air cold as a fan blows air across it ) is much colder than the outside air temperature ( usually between 38 and 55 degrees depending on the unit ). There is a basin or tray at the bottom of the unit that catches the condensation as it drips off the evaporator coil, and there is a drain that allows the water to drain form the unit. If this becomes plugged the water will build up and eventually drip out of the vents of the unit.
In the image, air is blown across the coil in the bottom left section of the picture ( this is the "cold' coil). Condensation can form on this.

The compressor and fan in the outdoor unit is functioning alright but the indoor unit fan is not blowing in cool air , in fact my split ac is not cooling at all. Is it something to do with the refrigerant?

Hello, first touch both pipes while the ac is running, the pipe with insulation should cold with condensation and the small pipe should be warm. If they are both warm then the unit is very low on refrigerant or completely out of refrigerant due to a leak, if this is the case you will need a hvac tech to come out, repair the leak, and recharge the unit.

If everything is working on the AC unit and the only problem is that not blowing cold air and instead the air is warm or regular temperature then your problem might be that you need to what is call recharge your unit with refrigerant. this is a common problem that can be solve easy by just adding more refrigerant to the unit

Wont no water to empty or drain

Either the unit is really dirty or it is low on refrigerant. A unit tha is low on refrigerant will start off cold and withing a few minutes, start warming up. If you aren't seeing any water its because of one or both causes listed.
