Also, as the O.P. mentioned, I extended the PVC pipe where the condensation drain terminates outside our house. As installed when the house was built, it stopped right between where the outdoor unit sits and the slab of the house (maybe 6" away from the slab)........and the turf did stay constantly wet there. After extending it, the drain pipe now runs out to the far side of the outdoor unit so it's about another 3' ft. beyond where it was before. Did it in such a way that the lawn mowing crew won't whack it while they're doing their job. Termites and other bugs like moisture so moving the drain line farther away from your slab is a good idea.

Excellent tip. I'll do it!
