How to extend HVAC ceiling vent through new soffit?


Go to a A/C supply house and get 1 roll of duct wrap- 1 1/2", 2 rolls silver tape, 1 can spray glue, 1 bucket white mastic. Around here the will sale to anyone for cash. I would suggest you catch an A/C guy, ask if he wants to earn money on the side. You can do this but, experienced man could knock it out in 2-3 hours. I would also have someone look at the rest of the ducts.

How to extend HVAC ceiling vent through new soffit?


That looks just like it does around most homes here in Chicagoland. Only a hand full of home I have seen that have the ducting wrapped. Wondering if it has to do with the even more humid environment that you have in FL than in the midwest. Not saying it's a bad idea, I just haven't seen many houses with that either.

If that's the case, then I certainly will look into insulating it. Any recommendations on what to use? Here's a better picture of the soffit from the other side. It runs almost the entire length of the steel beam. Thanks for the help.

I'm going to ask a friend of mine (GC) to get his opinion and I'll go from there. When I was doing some electrical stuff elsewhere, I saw the ducts on the 2nd level running between the joists and I don't think they were insulated either, so perhaps it's unnecessary here in the mid atlantic region? I'll have to do some digging I guess. Thanks.

According to another GC, insulating the ducting is unnecessary. So, I won't bother insulating it.
