The crawlspace mess

The A/C technician came out for evaluation today on why the airflow is so inconsistent. This could get expensive, but basically there are these problems:

1. Some of the ducts are either disconnected of ruptured (he put his right through a large one near the blower.

2. The ducts, most of them, are made of amaterial that was new in the early 90's, a grey flexible tubing that has since provento be a disaster. The flexing created by heat in the winter and cold in te summer causes them to crack and break. A couple of thee were replaced at some point, but at least eight have to be replaced.

2a. These ducts were installed by incompetent installers who used large cable ties to attach them. Sloppy, cheap and irresponsible.

3. The evaporator coil needs to be "deep cleaned." For an unknown length of time, the unit has been running without filters, which is disasterous for the evaporator. It could need replacement, which would be expensive, but hopefully a less expensive cleaning.

4. Something is living in one of the ducts and the technicial would not advance past it! I'll have to find and remove the animal/reptile, somehow, before any repairs can be made. There are small animal tracks, possibly a feral cat or a racoon. Either way it could be rabid. I may try to trap it with a humane trap. If that fails, another expense for animal removal.
This is likely because of the crawlspace door being detached, which I'll need to fix. My knees and back can't take being under there for very long.
