"Nice and" expression question.

Carol responds:
Except that a 68-degree house isn't nice and warm! Or is it, if you
live  in a cold climate? (BTW, I agree that Kemper's wording sounds
awkward. "Nice and set" combines combines an adjective and a past
participle. I would say, "The thermostat is set at a cool 68 degrees"
or "a nice, warm 72 degrees" if I had any say in the matter! Or "a
nice, cool 72 degrees" in summer.)
