AC question. Can a clogged drain pan

Yes

Yup

Fan comes on but compressor does not kick in, first thing I would check, but happens more frequently at the end of the season vs the beginning, regardless easy to check and fix

Yep

The pvc pipe coming out of the inside unit is what is clogged. The drain pan catches the water before it leaks all over your house, then uses a float switch to turn off the outside unit. Try to get the pvc unclogged with a shop vac or something that compresses air. I wouldn't use draino

A cap full of bleach down the pipe will usually do it.

Absolutely. Learned that the hard way in college.


Also learned (While in my fraternity house) the mind boggling fact that your air conditioner Pipes can FREEZE and stop working due to overworking during the summer while in your 110’ attic.

This is before i learned how cool science is.

If it's a Lennox unit, you probably need to have the POS coils replaced.
