For this job, the customer was having problems not having AC. I proceeded to check the air conditioning unit and found it has an ambient kit system. I found the compressor was working when I had the system on AC mode. I put my gauges on there to find the AC system low on refrigerant. so I proceeded to check the condenser coil and the evaporator coil with refrigerant leak detector. I was able to find snot and oil residue at the bottom of the evaporator coil in the front. So after talking with Aaron, he wanted me to add Freon and he will call the customer himself about the situation. I was able to add 1 pound and 6 ounces 410 a Freon. And was able to get the customer AC. As of right now, the customer AC is working
