Outlet temp
 

What would you expect the furnace outlet temp,measured right above the A coil, to be on my Goodman natural gas fired unit rated at 80,000 btu

Deleted duplicate post. What is up with this website today???

Outlet temp is the wrong measurement. You should check the temp differential between the return and the supply plenums. I am not sure of your exact model but the specs are generally something like 40-60 degrees F difference which depends a lot on the fan speed jumper setup.

arrrrrgggggg!!!!! :)

No kidding. It's been kicking me off or not finding the page and all types of crud today.

Very slow as well.

furnace will say somewhere the allowable temperature rise....if you want the heat exchanger to last do not exceed it.......:eek:
