Straight cool R22 install runs like a heat pump

I've been doing HVAC and building maintenance for most of the last 20 years. Most of my experience is on the maintenance and troubleshooting side and have done few installs of complete systems. I've installed a Trane five ton condensor and a Carrier five ton air handler. This is a R22 straight cool system. The problem is that when I run it the suction line is hot and the discharge is cool with the condensor fan blowing cool air with an ambient air temp of about 95 degrees. My gauge pressures are 150 suction and 130 discharge. I'm thinking I have a metering device issue but I'm not entirely sure. Trane condensor model # 2TWR3036A1000AA, serial # 8215K5P4F. Carrier air handler model # FB4ANF048, serial # 4096A19569. If I have the wrong metering device can you tell me what I need? I'm stumped.
