Re: 2001 Ford Escape A/C recharge?
1st check for a clogged cabin air filter. If your vehicle has one and hasn't been changed lately, it could be your problem.
I highly recommend having a professional do your A/C work! but here's a quick course.
Use 134A, charge on the low (cold) side with a/c on with fan on max and engine around 800-1000 rpm. Low pressure needs to be around 30 to 35psi with the valve on refrigerant can closed. If pressure reading drops, add a little from the can then close it off and observe pressure readings. Repeat until the system maintains between 30 - 35psi. Remove hose/gauge and replace port cap.
Be careful with refrigerants, can is under pressure and you can (freeze) burn yourself easily if you come in direct contact with the refrigerant.
Also, don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.
