Help- may be a stupid question. Goodman 16 seer, 2 ton, variable speed electric furnace with goodman cased coil, heat pump.
Here's the question- The coil paperwork says it has to be installed downstream (supply side) of the air handler but the air handler paperwork shows it on the return side of the air handler. I think I am short on air flow having the coil above the ahu on my downflow. HP switch tripping it off in heat.
Also, depending on whether you have an upflow or down flow will change which direction the air blows into the coil. Hard to describe, but the coil is shaped like an A. Do you want air across the coil to start at the point of the A and go down, or at the bottom of the A and blow towards the point?
