Go to the supply house and ask for an in-line tap! SSSSSSSSSShhhhhhhhhh(the mechanic might had connected the wrong end of the hose,(one end has a hole and the other end has a valve stem depresser to depress the valve stem to let in-out freon.. Or the older type, you have a king valve and has to be turned to open or close the ports!) ssssshhhhhhhhh!!

How to add freon in a centralized air conditioning unit

The compressor needs to be running.Also you need freon charging guages and a pressure temp chart to tell how much you need to add.
If your not sure of anything i said here have a service person do this.You take a risk of damaging the unit and yourself.

Ac not working,tried adding 134a ,but wouldnt take it inyo system.

There are 2 valves, a high and low. R134 should be charged on the high side (bigger fitting of the 2). If your system has no refrigerant in it then you may have a bigger problem than low freon like a leak.

When you charge it the air condition settings should be on high and running. This will help with the vacuum you need to charge it. There is a good chance the clutch is out on the a/c, if it the level is low it will make a clicking sound when engaged, if the level is too low it won't move at all. If this is the case you will need to add oil as well as refrigerant (this comes as a mixture, read the label on the can and it will tell you if it has oil in it).

After turning on the car, run the a/c on high, use the correct fitting and try adding the freon again, if it still won't take it then you'll have to get it serviced, most likely the air compressor is out.

I have a 220 window unit and won't get cold can I add freon and how

Generally, no. It's not normally a DIY project. Unless you have all the equipment (evaporator pump to remove and capture any freon (Now,R14) that's still in the unit, The high and low pressure gauges, etc). It's best left to the pros, as the unit may not be low on R14 gas. It may very well be a condensing sensor that has failed. Kent, there are a few times, when it's best left to the pros. And this is one of them. Especially, since yours is a 220 unit.

Hope I was able to help you. Please let me know. Thanks.

I have a fedders ac unit that does not put out cold air only for a couple of minutes. model # A2Q06F2BG-D can i add freon

Hello, you can add freon by installing a piercing valve on the low side of the system. Before adding freon I would check and make sure the air filter and both coils are clean. If everything is clean then most likey the unit has a leak and is low on freon.

Carrier Infinity System...would low freon cause a low pressure lockout? Could it be something as simple as changing the filter?

Yes and yes....
Could be either and they act a lot alike...
So make sure you filter is clean... the evaporator coil is completely deiced, and the blower is moving the proper amount of air for the unit you have... 300-400 CFM/ton...

Then if it is still locking out on low pressure, you are under charged...
do not try to add freon your self...

My Amanda wall unit keeps freezing up. Cleaned filter and coils, please advise. Thanks, Gilbert

If a AC unit starts to freeze up, then that is a sure sign that it is low on freon. A wall unit is harder to add freon to since those units generally do not have Shrader valves to purge or add freon. It is sort of like your refridgerator in that the freon is sealed in the factory and to add , a technician has to cut the evaporator tube and add a valve, then add freon, pinch the tube off and seal it once the correct pressure is adjusted.

I would say that somehow your unit has developed a leak, and will get worse.

I added a can of freon to my 2006 impala and the AC will not stay on the light cuts off

Get a freon charger with a guage and make sure the unit is at the right pressure when running. If the unit starts and then stops you usually need to add freon because the compressor is running dry because the charge cant keep up with demand.

Add freon slowly and be sure the ac is on. A small puff....and wait to see if compressor comes on. When it does you can add until the guage reads in range. Try to keep it in the mid to lower end of the range. Believe it or not the fuller units dont run as cool!

Be careful! Adding freon too fast to a compressor can cause "slugging" and can damage the system!

How do you add coolant to a goldstar air conditioner

There are two lines leading into the unit, the high side aND THE LOW SIDE. tO ADD FREON you need to add a valve to the low side line. But if you have a leak that indicates that moisture is in the unit and you need to pull a valum to remove the moisture before ADDING ANY FREON. There are as last known three types of freon, R22, R134a and this last one I dont even know the name.
