If you are only getting warm air out of the airducts with the AC turned on, it may be time for more freon. Also, if you hear a growling noise from the compressor when accelerating, that is also an indication of low freon.
Freon may need to be added when the ac is not blowing cold enough. A Freon gauge can tell you for sure if the pressure is low.
To fill an AC system with freon, you will need to locate the low-pressure port on the system, connect the freon canister to the port, and slowly release the freon into the system while the AC is running. It is important to follow the manufacturer's instructions and safety guidelines when handling freon.
I use a lime green crayon. If you need to get it out of your AC, you will need a freon reclamation machine that can bleed it out safely.
To put freon in an AC unit, you need to first locate the service valve on the unit. Then, attach a charging hose to the valve and connect it to a freon tank. Open the valve on the tank to allow freon to flow into the AC unit. Be sure to follow safety guidelines and regulations when handling freon.
you need to put the freon in the low side, should be the smallest cap on the ac system
ding freon will make it colder, only if freon is low. if freon is low you have a freon leak so adding will be wasting time and money. more likely to need a new ac temp thermostat, which is no big deal to change

To add freon to an AC system, you need to locate the service valves on the unit, connect a charging hose to the low-pressure valve, and slowly add the correct amount of freon while the AC is running. It's important to follow the manufacturer's instructions and safety guidelines when adding freon to an AC system.
To add freon to your AC unit, you need to locate the service valve on the unit, connect a charging hose to the valve, and slowly add the freon while monitoring the pressure levels. It is important to follow the manufacturer's instructions and safety guidelines when adding freon to your AC unit.
You'll need a pressure gauge and know how to use it. The gauge will tell you when you have the right amount in.

A machine that reclaims Freon is needed to remove the old Freon. The system will then need to have a vacuum pulled, and then the new Freon can be added.
