How to seal home air ducts and save money!

[farstarfilm]

BGreenHVAC dude I use duct tape been using it for over ten years sealling duct did that when we first moved in but with duct tape

[farstarfilm]

Pat, energy? Health is most important aspect of this problem can you tell me he name of this duct sealant paint? And where I can get it?

[InsideOutDuctSealing]

Return leaks do matter. Your filter does not catch everything and does not clean the air 100%. Return leakage causes outside air and pollutants into the duct system and pulls hot air in the summer and cold air in the winter into your duct system which translates to your equipment running alot longer than it would if it had a proplerly sealed return duct.

That house may be fairly new but those metal one-pane basement windows are old and drafty, like the originals I had in my 1953 ranch.

I replaced them myself with double-pane vinyl sliders. That's also a good way of saving energy.

YA THAT'S RIGHT, BEND YOUR LAZY ASS OVER AND PUT THE MAGNET ON RIGHT!

Returns in basements usually just run in between panned off joists anyway, there are plenty more return leaks, i'd concentrate on the supply

[asus3571]

cant you just use furnace tape???

[EmeraldBendInvestmen]

Great!

It doesn't matter what-so-ever if your return duct is sealed or not...All of your return air goes directly to the filter in your unit no matter what ! Your supply side is the only thing that matters of being sealed well. There are many units that have open air returns with no ducting....Guess you've never seen commercial hvac.

WOW ! What a rocket scientest he is !

i like the magnet idea and the enthusiasm!

[uodet]

very good Pat.

good idea about that magnetic strip.

I'm gonna recommend that.

[BGreenHVAC]

@uodet There is a commercially made product like the magnet he mentions. It still should have a metal door. I have seen somebody try a thin magnet on a commercial job. The magnet was sucked in and made a mess. He would have been better off if he insulated the supply. I'd much rather seal the supply than the return.

sweet thanks for these great tips

[filmerado]

Excellent presentation, I'm on it. Our house was built in 1878, and I need a tanker full.

[thejeztar]

they should have just used foil tape and a squeegee no mastic

[jnev1284]

@thejeztar You shouldnt use foil tape to seal duct leaks. Use Mastic sealant or mastic tape to get a truly tight seal.
