I love the results of the work you did. Even my wife, out of the blue the other day when it was really cold says she can’t believe what an overall improvement in the comfort level of the home. We’ve only been in the house a couple of months and so have no idea of what the heating bills were like before but just based on comfort level alone we are totally pleased. Not only that, before the duct sealing every time the furnace cut out there would be a minute or so of noises as the ducting contracted and that noise is gone now. Great additional benefit I was not expecting.
