I have called the furnace people to come have a look, in case it's the
blower or something. But if others think it's the thermostat, I may
cancel the appointment and try to fix myself. Any thoughts?

Any help is much appreciated. This forum has always been a great
resource.

Go and replace the thermostst anyway. Its a very cheap and easy way
to find if that is the problem. You end up with a new controller in
any event.
