We have had a leak something somewhere backing up causing our wood flooring to buckle from obvious water under flooring. Insurance told us to get a plumber out to identify the problem first. This guy shows up checks meter says no leak but had him look at drain in ac closet where it's been backing up off and on, he looks and says it's an ac problem. Tell me how a ac problem is buckling my wood floor from a ac problem when there is still water under the wood floor. I definitely do not recommend
