where are the return air (s) located?
master br suites require more than undercut of door.
best of luck
even well planned, well thought out installs
can run into suprises that slow the job.
an install in such a short time frame would have
to have everything go right.
best of luck.
in the 80's I bought a Mustang that the former owner
was a/c tech/mecahnic or mechanic/ac tech....
all the lines were copper braised...flanged..all copper.
it was an interesting project...many...
so you won't call them out on the 3 days when temps are extreme
or the 10 evenings you entertain & have a lot of activity in & out
of the house and more people inside the house.
return in ceiling.
now...is there a duct on the attic side of the return
or a sheet metal or duct board supply plenum back to the
see how the return is framed? the 2x's on the attic...
if you have duct leakage (if...LOL!) it will pull in dust/insulation
particles etc, along with air & humidity from attic into duct system.
if everything is mastic sealed, there will be no areas...
in your sealed basement thread I recommended that you take
jtrammel up on his offer. you should think about that after looking
at some of his posts & the pics.
can you post some pics?
jtrammel does some excellent sealed crawlspaces
& may could offer some valuable input.
personally...I'd never cut hole in supply or return plenum
to blow/suck from...
you should also make sure ductwork is mastic sealed & not
hit & miss caulk or duct tape. ducts @ supply plenum...
plenum connections to equipment.
ducts should be tight straight runs with no...
I'd only baffle the rafter bays with soffit vents.
unless insulation is deep at eaves and touching underside of
adding more soffit vents an option?
drill, skill saw..soffit...
just because it needs to be repeated.
if your indoor relative humidity is 70% and you keep the tstat in low 70's
with 75 being too hot...then you keep the fan set on auto so that it runs
all the time.
lets break that down a little....
BBB aside, you need an unbiased evaluation of the system as installed.
I'd start looking for another company that can provide this to you.
it is difficult to get one hvac company to correct...
like all hvac systems, install is what makes the system.
the install determines performance.
install always trumps brand IMO.
I agree that pro should be used...but either way, post pics.
rather than putting insulation on top of decking, you lift the decking by
toenailing 2x's into ceiling joists, increasing the depth of the joist bay
for more insulation. then decking is screwed to...
it has to be pulling (sucking) air from somewhere when
the blower is in use.
can you post info about what you had installed?
dust comes from insert...or where?
I'd need to know more info about...
Lack of knowledge on you builder and HVAC installer.
even though the v in hvac is venting.
then the storage space should be sealed air tight...take a look at the pdf's
different climate here, but curious about 600 sq ft upstairs area.
are walls of this second floor shared with attic?
if so...this is where you need to improve.
attic temps are more extreme in...
you can quiten it down by putting sound absorbing materials inside
every closet should be sheetrocked, from ceiling to r/a floor below.
most won't put batts in walls to reduce sound....
why not link the original thread to this one. makes it easier if it is all
under one thread.
