Upon arrival found system cooling. Checked inside unit and found that the blower speed wasn’t set up properly from install, adjusted blower speed. Checked safety float switch and it has a metal tip for a sensor that picks up water. Drain line was clear. Homeowner said husband cleared drain the other day. Which could of been the cause or water condensating onto sensor and would need to swap out for a different one. Checked Freon levels and found system slightly low. Added 1lb of 410-A. I did find that the speed tap for fan-on on the module for blower is bad motor can be warrantied out. Emailed quote
