There has been extensive and ongoing water damage in the utility room. The improperly installed A/C unit is just above this area as well as the improperly installed air box you can see in the picture above.
Here are some other pictures of the water intrusion over time as well as the falling insulation from an improperly installed attic chase which is a separate Lennar construction problem:
There are many construction issues happening in this area and they might be connected to the constant water intrusion in this area. There has been flooding on the wall of the electrical panel, which might explain the constant electrical issues, as well as extensive mold that has developed in the attic above. Additionally, the AV system you see in the pictures is the second one I’ve purchased and the second one that no longer works correctly.
This is one of many issues that Lennar indicated would be fixed – including the mold growth – through repairs additional inspections. These inspections have never happened. I haven’t heard back from the three Lennar executives I was working with for months.
