For the second time in perhaps 5 or 6 years, our central gas furnace / AC unit is dumping water down its rear wall when the A/C is running. This is bad, as the water runs down the rear drywall, collects on the foundation beneath the unit, and then flows out beneath our carpet (though not far).
The repair undertaken the previous time — cleaning some sort of fins deep inside the back of the unit — lasted for this many years, which I probably should be thankful for. But this hasn't been the only needed repair in that time.
The current unit, a Comfortmaker, was installed sometime in the early 90s, so I'd guess it's about fifteen years old. I've been told that the initial install was ... uh ... substandard, just from visual inspection, because the output/ducting right above the unit isn't really big enough to handle what the Comfortmaker can pump out. There are a couple of other visual items (and if I can see these things, you know they're obvious) that would point toward this, also.
Anyhow, my instincts tell me that I've put off this Expensive Homeowner's Adventure about as long as I can. It's probably time to bite the bullet and install a new central heat 'n' air system.
Any tips or ideas from readers? Things to look out for?
I can assure you: I'm all ears.
