I don't think so? I was going to comment that just like a/c units the seals will dry up if the unit isn't cycled intermittently. Remember the old manuals that would tell you to run your a/c every once a while in the winter to cycle the oil to keep the seals intact?I remember this thread. One change I have made as I used to unplug them for the winter as just figured it never kicks on and was using a trickle of electricity. Well with my current unit I stopped doing that and it has lasted longer than any previous unit. Maybe just a coincidence???
We used to keep a dehumidifier running in our house but the power bill hurt. Ended up putting new vapor barrier down in the crawlspace and updated the ductwork and a/c system. It's helped.
