Upon arrival found upstairs system had water in emergency drain pan, but drain line was dry, checked level of coil and it was leaning correctly, explained to homeowner that only was I can make sure if drain is clear I’ll have to blow it out. Also noticed downstairs uv light was out and drain pan rusted for upstairs unit. Homeowner approved clearing drain line and replacing pan. Will order pan, pan ordered and in will call at Lennox in Allen.
