The technician should have removed the cooling coil access panel on the unit hanging in the garage and physically cleaned the cooling coil and the drip pan under it... instead he opted to merely suck the clump of debris, that was blocking the drain out with a vacuum cleaner. or worse blow it back into the drain pan with air pressure... that is a very temporary fix at best.

If you want me to locate a more reputable company for you, tell me which direction you are from the center of the nearest city and I will get you a short list.


Regarding the damage to hood of your car.

It could be the slime mold that has caused the problem.

For that problem I would buy a can of 'rubbing compound' from an auto supply store and use the pad that comes in the can to rub out the affected area.

Then re-wax the hood.

We can go from there.
