It might be a combination of both. May be leaking heat from thin ceiling then roof which may but be well insulated. Andy there are only 2 vents up high blowing heat. Was not smartly right out when house was built, but other than tearing through the walls and doing a major Reno just for some extra duct work, not sure how to add more heat

Did that, my house isn’t a candidate for the cellulose blower. My issue was pretty much specific to just one area of the house, not the entire house. Thanks for the recommendation though.

Arthur’s in Medford on Somerville line. There’s really no comparison. Blows anything in the north end out of the water. I love a good cheese cake and have traveled extensively over the world, but their cheesecake is the best I’ve ever had.
