Heartland Cyclone Front A/C condensation

[yanceyprice]

Dealer just installed a Coleman-Mack 48000 series A/C. . It is leaking onto the floor.. Anyone knows where does the condensation go from the front A/C?


The whole underneath the by the tonque is soaked with water

Both front and rear on my current and previous TH had the condensation drain to the roof and would channel down either side and either front or rear of the rain channels.

Sounds like someone may have missed sealing something?

On our AC units if I remove the inside cover to access the filters I can see the gasket under the AC unit. If possible try this to get a peek at the gasket. There should be a gasket under the AC unit in between it and the roof.
Also another cause could be the gasket is compressed TOO MUCH and not allowed to do it's job. The gasket should be about 1/2 of the normal size after being installed. This should be around 1/2" thick.

As mentioned above the condensation from the unit should drain off the roof, so while having the AC open check to see if there is some drain opening from the AC. But this portion you need to be on the roof to get a good view.

This is the best place to start. The A/C units are not sealed with a liquid sealant, but instead, use a compressible gasket that is only supposed to be compressed so much. In this case, the gasket could be either not compressed enough, over-compressed, or could have been pinched in the installation process. The good news is that they usually flap in the roofing material, so hopefully the water is following that path and your actual decking is not getting wet.

I had the same problem.
The seal In the mixing box was leaking hot air return into the cold out side. Adding some more compressed foam stopped the leaking air from one side to the other. You need to go on the roof for the fix
