drain pipe from HVAC in attic dripping on to sheetrock
We had a new HV AC installed like 5 years ago in the attic. Had been running w/o issue. About 2 months ago we had the sheetrock in ceiling ripped out and replaced.
Now, after having AC running for last week as weather has warmed, i noticed something. I heard a dripping sound this AM and looked up in kitchen and say water dripping from the corner of the room, just at the edge of ceiling. Crawled up in attic to check out and noticed that a 1" diameter PVC pipe connencted to AC unit in attic was dripping water onto ceiling. I've never had this problem in 5 years, so don't know if sheetrock guys accidentally ripped off connecting piece that ran to outside of house or if this drain pipe has been laying there all this time w/o any drainage coming out. There are actually two PVC drain pipes, one shooting off in direction of cooling pipe(thick, black wrapped pipe running from AC unit outside to system in attic) and this one. The former actually runs to outside of house. The one dripping inside attic is not, though there is some silicon on outside of pipe, indicating that maybe another piece was connected to it at some point.
Anyway, the pipe in question is running in the direction of a framed overhang that shades my front porch. I looked outside to see if there was a drain hole outside house where pipe would have drained to, and see nothing, though where it is aimed at there is a structured overhang that shades front porch, meaning the exterior frame of house on that side actually doesn't see outside of house, as there is the framed porch overhang. So even if there were PVC pipe that got separated that led outside it would have no where to go that i can see, so maybe it has been laying there in attic all along.
Anyways, i guess i need to call HVAC people and ask them to check it out? Is there anyway i could fix this myslef, assuming HVAC people will want funds to look at it? Is this normal in HVAC installation, to have a drain pipe just laying in middle of house?
Kinda pissed cause new ceiling got wet, about a 4"x12" area, right at corner of room. It will dry and be ok, right, though will have to Kilz and paint it? It's 5/8" variety. I had a left over piece from construction sitting outside in rain for 2 weeks and it's dry as a bone now, with integrity seemingly in tact.
Appreciate any help, and congratulations on reaching end of this diatribe.
