I recently had a home efficiency audit performed on my house. The results were mostly good, but they did say that my ductwork needed to be sealed more effectively. Apparently, when they turned on one of my A/C units (I have swamp coolers), they were able to feel cold air pouring out through the roof at the point where the unit met the house.
They quoted me about $700 to fix this (as well as seal around the, um... registers?). I don't know if this is high, but assume so since they also quoted me $1000 to add more insulation (something my boyfriend and I can do for ~$250 and a day of our time).
Can anyone offer any tips on how to best seal up the inlet? I have access to both the roof and the attic side of the connection.
Also, the silver casing on this tube is torn here and there. I can see the yellow stuff inside. Is that something I can simply repair with tape (not the dull duct tape, but the shiny stuff)?
Am I better off just hiring someone?
Thanks in advance for any help you can offer!
