We're running ceiling fans in all rooms (cept bathroom of course) On high in the rooms we habitate t he most and on low in others.
I am wondering if the ceiling fan's electric junction boxes are sealed around the penetration opening. If not, the ceiling fan could be drawing hot attic air into conditioned rooms as it runs. Just a thought.
plz give the exact locations of the temp probes/thermometers. Super novice here.
After the air handler, there is usually a flexible fabric "boot" that joins the air handler to your house ductwork if you have an upflow air handler. The boot is a great place to poke a small hole for the temp probe for measuring the air temp after the coil.
For the supply air temp, see if you can find/poke/drill a small hole in the duct or plenum just before the air handler.
