HELP: Leak through PTAC Unit when it rains

1:33 PM 02/27/2013

Park Slope, NY

Hello,
I live in a New Developement building with PTAC units made from a manufacturer called "Suburban".  As you can see from the picture after a heavy windy storm somehow we get water under out floor boards.  I have opened up the unit to the best of my abilities and still cannot find the source of the leak nor the way to fix it.  My Condo sponsor is a lame-duck who says that the wind is so strong that the water finds it way through the PTAC unit into the building.  I've called a PTAC specialist who says there is nothing he can do and instead suggests hiring a contractor to come in.
Any advice on what to do / who to call?  We do live in a very windy corner of the slope and we get this wetness only when its a very windy rain-storm.  
Thanks

    I have a similar problem with certain windy rains and my tenant's roof top ac.  I'm going to try replacing the insulation near where the vents are located.  What's happening outside at your place?  Is there a grill?

      Elbow, I have a similar problem with windy rain and my rooftop ac unit. I get a leak through and around my return air vent. I've had roofer cover the duct on the roof with roofing material and had another roofer try repairs around the ductwork on the roof but nothing has worked. I even had an HVAC guy come look at the rooftop unit and he assures me water couldn't be getting into the unit and leaking down the vent. What insulation are you planning on replacing?

      There's a blanket of foil covered fiberglass, part of which blew out in the tornado, more in the tornado. I think the lid wasn't on tight, because that blew off, too.

    Elbow, my PTAC unit is an in-wall unit that has electric AC and gas heat.  Yes there is a grill air duct on the outside of the building for this PTAC unit

    Can you get to the grill?  Caulk can work wonders and it's cheap enough that you can try it even if it doesn't work.
