Warranty: customer was concerned about unit not cooling properly. After looking into issues discover that the meter device was causing pressures to fluctuate. Sensing bulb possibly lost charge, tried insulating bulb better and it did not make much of a change. Coil is under warranty and will get customer back on the schedule to get the txv changed out. Came back out to install new txv. Pressures are much better currently with a 14 degree split
