i have a lennox furnace model C23-41WFC-1 that is leaking very heavy from arrow in pic when the ac kicks on. whats the best action plan to stop it?

check the drain, its probably plugged and the condensation isnt draining out.

need to dismantle that fitting where it comes out of the coil and clean the debris out of it. I don't like glued joints like that for that reason. I would convert it to a clear hose and connect that to the drain pipe with hose/gear clamps and put a new fitting on the coil. get a Pro to do it if you don't know how.

thanks again
