Thanks so much for everyone's help. This forum is great. I hooked up my gauges this evening and it was 95 deg outside. The compressor was cycling on and off with the high side pressure cycling from 350-450psi and the low side cycling from 70-80psi. Keep in mind the system has been vacuumed and recharged twice so I am confident the system is not overcharged. I have a brand new Denso compressor, condenser, dryer, and expansion valve. Clearly my pressure is too high. Where do I begin to troubleshoot and fix this? Thanks in advance!!
