HVAC help/question

[BMAC_GTX]

Since we bought our house last december there has been a large amount of fibers floating around in the house and dust. As soon as you clean it up it comes right back. At first I thought that it was from the carpet upstairs, but we hardly ever go up there to stir it up and we don't capture that much when vacuming. Downstairs is wood and tile. The AC unit is in the attic and is for both up and downstairs, has dampers. I'm wondering if the unit in the attic is sucking up the fibers from the spay in insulation and dispersing it thoughout the house? Has anyone heard of this before or how I could check this theory.

I switched over to good filters as soon as we bought the house and it didn't help.

Get a company who does a duct pressure test make sure on the return and supply has no leaks and drawing in attic insulation

There is many reasons to have this issue. But yes the best thing is too have someone that is trained in Indoor Air Quality come out and look, not your average ac guy is.

LOL>>>>>>test a residential system with no static>>>>>LOL >>>>nevermind the rest of what i want to say

You saying there is no static pressure in a residential system? And the blower door static test show no leakage or problems with ductwork?? Bring it on and post up your state license number and qualifications while your at it mine and available on request

You just made me really laugh.....there is no static possible in a residential system with a central return>>>> Carry on apprentice

Undersized r/a? High static filtration? Kinked flex duct? None of that is contributing to pressure in the ductwork itself? And a blower door test doesn't test for return or supply air leaks? In not speaking of negative or positive whole house pressures I'm talking with in your ducts and unit. http://energytrust.org/residential/incentives/Weatherization/AirSealing

Read up before judging and comming with tude bro. We do it different down in Texas I guess but feel free to loom me up when you want a beer you can find my info TACLB#30249E I love talking about ac

Im going to give you a chane not to get a rep as a dummmmbbbasss......want to know my quals huh? OK....BTJ Journeyman Local Union 597 Chicago Ill and 155 Little Rock AR....Journeyman lay out and fab sheet metal...journeyman boilermaker....Master Electrian Illinois, Wisconsin and Arkansas, Med Gas cert all three states, nuclear control welding cert USA....reactor head cert USA....many more to list.....still wanna talk?????

[Uncle Saggy]

I'm going to quit talking hvac on this site.....Ellis and Airhead are the real deal....stick with them

[Twztid]

Don't see any ac stuff In there but I'll take your work for it I appreciate the talk bro! He's got dust! I'll just be an ingrate ac guy BUY a new system! Compared to uncle saggy? Check your ducts make sure your not drawing in attic air or dust from other areas...

Saggy this could have went different but your quick to attack about somthing your not aware of but it's ok still love you mabey you show me how to weld somthing with a welding degree?

There is and will be static pressure in any central air system. Most common are the filter itself people think the high dollar thick filters from home depot are the answer to dust and air quality when in fact they create more static pressure in the system. Also most duct systems that have a lot of compression (duct not stretched and ran straight and hung properly is another that I c alot of uneducated installers do. But regardless there will always be some static. A blower door test is designed to put the house in a positive or negative pressure to determine where the house is leaking. I would guess though in this case I have a feeling there a leak in the return duct.

Do you notice the fibers on the filter when you change it?

[elliscountyhog]

Thanks saggy on the compliments. And not calling you wrong maybe just misunderstood and I am no means a pro at our industry I am always learning. So is there a way for a central air to have no static pressure? Btw nice credentials I can barley pass one state

Gawd thank you walkerac! I could not explain it the way you did but what you said was the point I was tryin' to get across.

Funny....was thinking of actually being nice to you until you threw in the welding degree and question mark comment.... Listen idiot.....my welding certs are not from a vo-tech , school, within a company training program..........y'all are what we call test booth wonders......my certs are from 30 years in the field and busting my body>>>>>bet your dumb arse was sharting green while I was doing this for a living and raising a family
