could have too much freon in it -air could be going thru heater coil- no air flow thru condensor
It might be overcharged. Or you might have contaminants in the system like air or acid.
There are a few reasons your AC might not get very cold even though the Freon is fine. You could have a leak in your line.
using a can of the proper type of Freon, connect a gauge and the Freon to the low side ac port. With the engine and ac running, open the valve and allow the Freon to flow until the gauge shows full. Read the directions on the can and be mindful of the can, as the out side of it gets cold enough for your hand to stick to it.
You gonna need to add Freon. Real cheap an easy fix. If your Freon is full an still the AC is working. Most likely gonna be your AC pump. That's not cheap. Cost me more the a few hundred getting mine replaced last year.
Yes. Freon is for keeping the AC cold
Look to see if the compressor is running when the ac is on. If not, then check the Freon pressure, as the compressor won't run if the Freon is low.
Connect a freon gauge and the freon can to the low side ac port. With the ac running on high and the engine running, open the freon. Let it flow until the gauge shows that the system is full.
Connect a freon gauge and freon tank to the low side ac port. With the engine running and ac on high, open the freon tank to fill the system to the full line on the gauge.
With the Freon and gauge connected to the low side ac port, start the engine. Turn ac on high, and add Freon till the gauge shows full.
Connect a freon gauge and freon can to the low side ac port. Start the engine and turn the ac on high. Open the valve to allow the freon to flow until the gauge reads full.
connect a Freon gauge and Freon tank to the low side ac port. After starting the engine and putting ac on high, open the Freon valve. Watch the gauge until the Freon is full.
