My AC was struggling to stay at 78 degrees this weekend while the
temperature outside was 88. In fact, it seemed to run all day
without stopping because it could not get the house to 78. It was
hanging around 79.

I noticed a few things. First, the air pressure coming out of the
vents seemed low. I recall being able to hear the air at times in
the past. Now I have to put my hand over the vent to see if the air
is on. Second, the air coming out does not seem that cold. Third,
the secondary drip pan, under the unit in the attic had a lot of
water in it (not sure if that is meaningful). Fourth, I openened a
vent in my crawl space and the air under the house felt very cold.

Everything I have read so far suggests that I need a coolant
recharge. And that I probably have a leak. Does that sound right? If
so, how do I go about finding the leak myself? I prefer to try to
cut down on the cost of the repair.

The other thought is that I might have leaky duct work under the
house, hence the cool air there.

Thoughts? Opinions? How much does a recharge cost these days? I live
in the Raliegh NC area.

Thanks!

Not sure where you conclude you need a coolant recharge, everything you
describe points to a damaged duct in your crawl space dumping the cooled
air into that space. Suit up and go in and inspect the ductwork for
damage. Could be as simple as a broken duct clamp.
