What's going on -- Vents are blowing hot air and
It sounds like the unit is stuck in the heat mode or the thermostat switch is still on heat. If the switch is in cool then you can go to the outside unit and locate the reversing valve. It may be stuck in the heat position. You can tap it with the handle of a screwdriver but only on the ends and very lightly because if you dent it the valve will be stuck for sure. If it shifts you will hear a loud hiss as the pressure equalizes. You could also try unplugging it from the circuit board. On some units it is energized in the cool mode and on others it is energized in the heat mode.

I need to know the correct high/low freon setting
Listen the easiest way is to add freon on the low side until the line starts sweating. This is the quickest way to do it. The other way you have to know your wet bulb temp on the low side line the outside temp the inside temp at the intake and the ambient temp outside this is complicated and works no better than the sweat method i described.
How much r-22 refrigerant can
It all depends up on whats the brand and model number on the commercial AC system.Some are high capacity and some are low capacity, commercial AC system.---------
If the less refrigerant will be added then it will not cool properly, if over refrigerant is added then it will spoil the compressor .So all depends up on its exact model and brand.---------
Basically all the details should be mentioned on the AC system.There is a sticker on its left or right or front or back.On that all details should be mentioned.---------------
-----------------
This is example of what it writes on the sticker.---------
HCFC-22 3lbs. 14oz. or 1.76 kg
------------
Mostly its written in this type.-------This means that this system uses R22 Freon (HydroChloroFluoroCarbon) and this unit takes three pounds and 14 ounces of Freon or its equivalent weight of 1.76 kilograms.
---------
So you have to just locate the sticker on the AC system.And this will help, you to confirm, how much refrigerant it actually takes.
---------
This will help.Thanks.Helpmech.
My outside unit is working,
You need to check the inside fan. Check the inside unit (where you change the filter), Open the panels and turn on the A/C Look for a panel switch located on the frame where you removed the panel and if there is a switch press it in. Listen for your fan to be turning, any scraping, scratching, means worn bearings, slow turning means bad relay, or capacitor. Hope this helps Fixya up.
How do i put freon
First off, Freon is no longer approve and has been banded by the EPA R134a refrigerant is what is now approved. You will also need to have the proper gauges and pressure lines to attach to the compressor, to delivery the refrigerant gas. But, before you can do that, you must purge and capture any of the remaining Freon gas left in the compressor. The 2 different type of refrigerant gases shouldn't be mixed. Capturing the Freon requires a purging pump and tank.
After reading the above, if you still want to do it yourself, go by your local auto repair store and purchase all the equipment (Gauges and hoses set up for testing the high and low sides of the compressor) you'll need,. It usually comes as a kit for a little less than $100.00. Plus, 3 cans of R134a refrigerant. You'll probably only need 2, but having an extra one is safer. When you get back home, use the Owner's Manual for the AC unit, to determine what the pressure should be on the high and low sides of the compressor, as well as the where the refrigerant ports on the compressor are.
I hope all this helped you and thanks for choosing FixYa.
I have central air and
Is the compressor starting? On the outdoor unit you will see a large copper pipe and a small copper pipe. Is the larger of the two cold to the touch? wet? Just because a central air system is not blowing cool air does not mean it needs freon. If you have clogged filters it cannot do an air exchange. So, I would recommend checking the easiest things first before adding Freon.Most people make the mistake of adding Freon and overcharge their system. In a low load situation you can slug the compressor with liquid and your system is ruined. If you do have to add Freon it indicates that you have a leak. An AC System is a closed system and if it is working properly you should not have to add Freon.
I live in a trailor
There are several things you can try .If you don't have shade then try putting aluminum foil on the inside of the widow and scotch tape it in place. Leave curtains shut and leave the blankets up if you want. The foil will help reflect the heat build up through the glass.If possible if you have storm windows on then place the foil on the glass closest to the outside. This will help more by not letting ultra violet rays into your house which get trap and cause heat build up.
Clean or replace air filter and squirrel cage on blower to make it move more air. You can also make sure all vents are clean and vacumn out as much of your duct work as you can reach.
On the outside unit if you have a lot of grass or weeds growing around the condenser unit then cut or pull them to provide good air flow. Shut main power off to outside and use garden hose with a pressure nozzle on it and wash all the fins and coils you can.
It's just a rule of thumb but you can feel the copper lines to the condenser while the unit is running. the large line should be cool to cold and have condensation on it while the small line should be much warmer. If they are not you may need to have a service tech. check the pressures and add if needed. Best of luck.It's 108 here today so I sure hope any of this helps you. Thank you.
If your a/c is blowing
Have the unit tested for proper refrigerant level and have the unit checked for any mechanical issue that would prevent the compressor from turning on
