Had two inspects yesterday one a slab on grade and one a crawl space both had leaking A-coil pans.
On the crawl space I knew that there were A/C problems before I ever enter the crawl. While making the tour of the exterior foundation I noticed a very small amount of condensate being discharged from the external condensate drain line and yesterday was a very high humidity day and there should have been a large volume of water being discharged also while passing the foundation vents I noticed cooler air discharging from the vents. My foundation tour told me two things Charley you need to pay attention to the A-coil pan and you need to look for duct separation in the crawl.
I found both problems when I entered the crawl space the Supply plenum had water dripping out of the bottom and the sub-flooring was all wet Also found a 8 inch supply duct separated discharging into the crawl.
Point being know your red flags as they can guide you in the right direction in detecting problems.
Knowing that I had crawl space problems that were obvious to me from external to the foundation I had to make the decision to enter the crawl space which had raw fecal in front of the crawl hole. Would you have entered or deferred it???
