Had my duct work in my house sealed yesterday via Aeroseal: I had suspected much of my energy bill might be going up in smoke, given the snow melting patterns on my roof, but I had no idea... One zone of the heating system, the one that has been operating the most, was losing just over 50% of the heat to leaks in the ducts. It will be interesting to see what my energy bills do now.
I won a very dubious honor: setting the record for leakiest duct work in a heating system for the contractor, along with running them out of sealing solution, which they had never had happen before. The company that did the work is the one on this ATOH episode, Boucher Energy Systems.
In any case, one blow for my pocket book, and against global warming, and I hope my kids will find their rooms more comfortable.
