Installing Flexible Duct - Insulated Duct - DIY

[MrPiratefish]

The grey duct you were working with is an R-4 R value, it was made in the 1980's and is inferior to more modern R-6 or R-8 insulated duct. That grey duct falls apart if uv light from a roof vent (or other source) hits it, the duct liner did not have uv hardener in it an I've replaced miles of it. Another tip is to tuck the outer liner back under the insulation concealing the insulation, should be no insulation showing and "tuck" should rest up agaist the plenum and also be sealed with mastic.

@MrPiratefish Great tip and it makes sense. I wish every HVAC installer was as professional as you.

Hey Corey,

Great simple video - I had just installed some flexible duct incorrectly! Now I can go back and fix it correctly.

I enjoy your website - keep it up!

Just a note on this video - you may want to mention something about the damper lever you are covering up and how to properly maintain exposure/access without ruining the insulating seal.

Thanks again for your work!

Hey Jim, Thanks for watching and commenting! Sometimes it's tough to figure out what to include in the videos because not everyone has dampers, etc.

All I did was cut a hole through the vapor barrier and the fiberglass layer. That way I can see the damper and adjust it if necessary.

Take it easy,

Corey

thanks corey

in your video you said $1000 per month heating and electric. My highest ever is $450. Couple years ago I insulated the heating ducts. The leaks contributed as well as the heating ducts were uninsulated. Back to saving money on my end.

@gregory747 I watched your video on insulating your ductwork. Great Job! Especially for such tough working conditions. That was a tough job.

Sealing the ducts is definitely critical. I have 2 heating systems and both were terrible. I can't believe the heating contractors don't seal the ducts or even seem to care. I'm saving a ton of money since I've insulated and air sealed my house and duct work. Our bills were down to $350 last year and I'm so glad I did it.

Keep up the good work!

We are really enjoying the cooler weather in north ms.

Wife just mentioned tonight at supper that we're really saving on utilities the past few days.But I will ck all of our duct work connections tomorrow.

Thanks Corey

@1betrman I'm loving the weather here in the Northeast, too. I wish it could be like this all year long.

Look for smaller leaks around your main HVAC trunk and branch ducts. They are always leaky.

With heating oil near $4/gallon, and the economy in the toilet. I need to make sure every dollar I spend on heat makes it into my house.

Thanks for watching,

Corey
