Upon arrival system was not cooling. I checked float switch and there was water in float switch. I flushed drain line again. I put chemical down and let it sit for 20 mins. I flushed down the drain line with the vacuum. I grabbed a water hose and shot water from the outside pipe. I did that 3 times. I attached my vacuum again to vacuum out the water and then i poured down 4 gallons of water down while vacuum is connected outside. If we have to return again because of the same issue. We would have to hit the drain with nitrogen. If it’s an ongoing issue we would recommend a condensate pump. Customer showed me pictures of the unit icieing up. I informed her it could be the txv. The filter is clean and I checked the pressures last time I was here.
