Check your caulking around any areas that get wet or wiped down often & recaulk. I just redid mine- much cheaper to do it than repair a water leak, especially if you’re in a condo & it impacts your neighbor in the unit under! Kitchen counters, under mounted sinks, laundry room, bathroom vanities & tub / showers are all areas to inspect. Remove the old caulk, apply new & let it dry at least 24 hours.

Also replace your AC filter at least 2x a year to make your AC system last longer. If your filter is clogged your system has to work harder & damn, those things get pricy!
