Came out for a maintenance upon arrival. Customer had no concerns looked over both machines inside and out found drain line was a little clogged so I put some treatment down it to undo the clog. There is no clog and is flowing nicely upon checking air handler inside found a bunch of growth around the outside of the air handler and on the inside Need to get with James and figure out pricing for that and what we should do also need to have somebody return out here to move the thermostat from behind the TV to closer to the hallway.
