The shop vac suggestion is an excellent idea, thank you! I do have a wet/dry shop vac and those ingenious gadgets can be very handy. Definitely something to try before summoning a repair flunky. I think I last used it to do drywall sanding back in the days of much greater agility and ambition!
But I have to wait for sustained heat and humidity to see which hose is discharging water, and if the shop vac fixes the problem. That should be hitting us within the next few days.
