Good common sense replies, all. Thank you.
There is a good strong air current coming through the registers which tells me that the duct is alright. So, I turned the heat up from 65 to 80 and will stop by in the morning to see if it's like an oven. Of course, other thoughts, it could be that after living in a good cents house for the last 20 years, now we have the realities of thinner walls and insulation, and heating systems that leave us scrambling to find out where we packed the sweaters.
I'm not sure what to expect pertaining to the heat. Should it be able to get really warm? It is winter outside with temps below freezing.
