Christopher Gruenwald: That's a good start, but the bigger problem is fiberglass insulation. You
can heat a spray foam insulated home for practically nothing.
Keyzer4: Another novel idea that people are liking these days is putting your
ductwork inside your conditioned space! wow! My delta T suddenly isn't
close to 100 degrees! Not so hot for retrofits, though.
Also, "Duct Tape" Doesn't work on ducts. You need to use mastic or butyl
backed tape. That doesn't help if you don't have access to the ducts,
though. But then, if you don't have access to them, they're probably inside
your envelope. Mastic is a few bucks & you can apply it yourself. Aeorseal
is... not a few bucks.
edit: don't forget to prioritize those return ducts, though. you don't want
any backdrafting. it can kill ya.
David Jones: Does this work on flex duct systems??
Please let me know.. I am in south Florida and most systems are 90% flex..
Thanks for your help.
TheTread123: I can see where this product is useful in condominiums where in the typical
room there is no return air vent. Also will reveal shoddy insulation work
in closets that adjacent to outside walls.
Adam McClusky: terrific explanation
National Heating & Air Conditioning Co: Sealing ducts from the inside is 50 times more effective than sealing them
from the outside. This is the only DOE approved process. #ductseal

Michael Madrigal: when using aerolseal do you have to isolate the return and supply from the
fau and indoor coil so there are no external static pressure added the
rated furnace/ coil.
Ruckus Piper: sounds pretty expensive
bayareahvac: In most cases fixing/sealing air duct leaks sounds easier then it is. Many
leaks are very small, so it's difficult to locate 100% of them. Air ducts
are sometimes located in walls, floors, etc, so they can't be accessed
without extra expense. Aeroseal seals air duct leaks from the inside out,
the sealant mist will find the leaks, and seal them. If you need more
information please contact us.
acboy100: I call Bullcrap!!!! I own my own AC company, dont see this stuff being
worth the value.. Just hire some mexican to get in the attic or crawlspace
with a bucket of sealant and fix it for 50 bucks.. Just saying.
compdude957: awesome, do they put a plug where the ductwork meets the furnace? otherwise
that stuff will start to seal your coils, heat exchanger, and blower. We
need this done to our house
bayareahvac: Yes equipment (furnace,coil, air handler,etc.) is sealed from the duct
system before the Aeroseal process is started. If you are in our service
area, give us a call at 888-WOW-COOL.
uladula68: or you could just fix your duct
Joseph Reynolds: Yes , Michael you completely isolate the HVAC unit. Aeroseal allows the
option to seal both return and supply ducts simultaneously.
arm mel: I would like to know what AC company acboy100 owns, so I know who not to
recommend. Those type of comments really shows people the kind of people
you are letting in your home. Scary to think about! Just saying
Mark Morrell: Typical infoscamercial...blind em with science and tech talk and then come
with the pitch.
John Porterfield: Simple tests often pinpoint a problem that "a bucket of (mastic) sealant"
will inexpensively remedy. Duct problems often account for 35% of heating
energy use, however video overstates duct leakage to outdoors, one of five
common duct defects. More common: too much air to one room can cause house
infiltration to increase. Knowledgeable independent energy audit, test &
plan first, beats "quick fix." Be careful. Leaky return ducts may cause CO
hazard - more likely if ONLY supply ducts are sealed!
Joseph Reynolds: Mark, It may sound like one , but as a lead technician @ Aeroseal of the
Lowcountry the process WORKS!!!! We not only test the system but give proof
