I live in New England and run my basement dehumidifier from mid-June to mid-September.  I had owned another national brand dehumidifier, but it failed after 3 years.  I replaced it with the same national brand dehumidifier, but within a week the humidity sensor wasn't working correctly, so I returned it.  I then bought a Frigidaire 35-pint capacity dehumidifier, and it's been running reliably.  It's quiet and I'm very happy I changed brands.
