Upon arrival system was not on. I checked system and float switch was tripped. Water in float switch. I flushed drain line with vacuum and water hose. A lot of gunk came out. I was not getting a suction from the vacuum at the air handler. After I flushed drain line drain was getting great suction. Customer paid $79 service fee for today. Customer was fussing about the the price on the drain line treatment and that we have had to come out here a couple of times for the same issue. so I just charged him the service fee.
