Question about Whirlwind FH-778 Air Conditioner
My home AC was low on freon. I had a cert. tech charge the system back up to where it should be, but he never checked for leaks. 4 weeks later, same problem. I used soapy water to locate the leak myself, which is on a copper pipe just outside the condensor coils. My question is, is it ok to solder up the leak without removing the freon from the system, or would this be dangerous?
You need to have the system evacuated to fix this leak. First thing is for safty reasons, for your protection and refrigerant release. second is to make sure no contaminates are released inside your system. The tech should recover the refrigerant fix the leak, then purge with nitrogen, then pull a deep vaccum to 500 microns and it should hold for 20 mins. then he should recharge the system with refrigerant.
Hope this helps

1. use stop leak,(New heavy-duty stopleak product XL-4 ) because it is very difficult to find where is leaking.
2. connect to the low pressure fitting of the condenser and use the A/C gage meter to add ES-22a or R-22 until reach to 75 to 85 psi if the temperature is around 90 degree.
3. turn on the A/C and re-charge ES-22a or R-22.
4.If you do not know how to do it,hire a professional A/C man to do it.
