Purchased the unit last summer 2021 and it worked great up to about 2 months ago. It seems to work fine most of the time during the night but during the day, it doesn't. Strange for sure but who knows, perhaps because the home (therefore unit) is colder at night. I haven't done a warranty claim for anything in years so I was not looking forward to the experience but I will say that NewAir has been great with response and offered opportunity with a no harassment replacement.
