After the past 4 weeks on the Florida Gulf Coast and lots of hot humid days, my bedroom a/c started a very small drip on the bed. I caught it very early and checked the 4 hold down bolts after removing the filter register. The two front ones were not even hand tight and the two rear ones were tighter. I tightened up the front ones to hand tight plus 1/4 turn with a wrench. No more leak.
This was the first time in 3 years I have had to tighten these bolts.
