Sounds like your compressor is disengaging once it heats up. There a DIY on here on how to remove some shims to make it make contact even once heated up. Other option is to replace compressorHey guys. My 8th gen blows ice cold air and then the compressor turns off after about 8 minutes. The system does have pressure/Freon. Has been doing the same since last year, where should I start?
