Thank you.

Is the indoor blower in attic?

Customer: replied 3 months ago.
Customer: replied 3 months ago.
I just got the outdoor condenser replaced a month ago. I also changed out thermostat. Everything has been running smoothly for the last month.
Expert:  BillyHvac replied 3 months ago.

can you check the drain off the attic unit or look for water in drain pan?

Customer: replied 3 months ago.
Could we try another method? I'd prefer to avoid the attic because it's difficult to get into. If necessary I will though.
Expert:  BillyHvac replied 3 months ago.

The number one failure of attic units is a plugged drain...which then trips a safety switch to turn off ac so no water damage.

Lets try one thing first though...take thermostat top section off...locate red wire on R terminal and green on G...use a paperclip or wire shaped in a U and hold one end on R while other end on G...tell me if indoor blower starts

Customer: replied 3 months ago.
Ok thank you. Do you want me to put the paper clip in the holes of r and g where the wires are in?
Expert:  BillyHvac replied 3 months ago.

any way we can create a connection between the 2

Customer: replied 3 months ago.
ok, I tried it but nothing happened
Expert:  BillyHvac replied 3 months ago.

thank you....do you know if the drain terminates outside somewhere from the indoor ac?

Customer: replied 3 months ago.
I do not know sorry
Expert:  BillyHvac replied 3 months ago.

ok,

well we are at that point...I know you rather not check the attic unit...but that is the point we are at. If you can at a minimum trace the drain pipe from the attic unit..or just take pics and post here and I can mark the pics with directions
