We put a cassette in a bottled water companies sales office, it was ok till they installed their filtering and bottling plant in the warehouse, but after this the whole thing sweated as the air was so humind! Had to insulate the case of the cassette and the drain line, plus the sparky had cabletied his cables to out line set and squashed the insulation which also dripped.
Trying to decide if I should insulate my air handler as I live in fl with the air handler in the garage but still see temps of 95+ in the garage and tons of humidity with my air handler sweating all summer long. This video has made me decide to insulate the whole outside of the air handler. Thanks!
“Comes from experience” but isn’t a correct solution. It’s a bandaid based on “guesswork”. In reality, and backed up by the books, Attic needs to be sealed and dehumidified. Dewpoint in being reached on that ahus surface.
all the sudden mine blows steam/condensation out the roof vent and it has my rafters all damp and dripping in just the area from where the vent sticks out the roof. No explanation, just started doing it when I turn the heat on. Any ideas?
THE PROBLEM IS VERY CLEAR, THE CUSTOMER HAS THE THERMOSTAT SET BELOW 65!! ITS AIR CONDITIONING! NOT REFRIGERATION!! Typically in memphis Tn. we have attic temps 130-150 and no sweating, using the factory insulated cabinet. Yes, our humidity is very high as well. Typically you need to check the CFM if the cabinet is sweating profusely! But seriously, 66 return!
Would not want to hire the angry HVAC Xpert. We keep our house at 73 and have the same issue with Handler sweating in attic. Factory Insulated cabinet is BS
@@robjs10281 - how did you solve the handler sweating problems in the Attic? I have two units in the Attic. Inside house temperature set at 75 degrees during the day and 72 degrees at night. I had air vents added to the roof but I am still having sweating problems. I live in Texas and it has been hot. Rob, how do i solve the swearing issues on my Units?? Thanks.
David - my plenum has excessive sweating. The unit is in the attic. You talked about insulating the Plenum with some kind of material to prevent sweat. Where do I get the right plenum insulation material? Can I apply the Air Duct Installation cement to make the Plenum walls thinker to prevent sweating?? Thanks.
I'm in Galveston Texas and having the same problem it's okay to wrap the exterior of that air handler saw another video where they were in Slaton the interior
I think I’m going Through that situation right now the customer seems to like really cold air and I have a 4 ton variable speed Goodman I just installed and it’s sweating like a whore in church🧐
Jones - where can I get the air conditioner’s wrapping material to prevent sweating on the outside of my unit? Excessive sweating seems to cause black/brown spots which I tend to think it will cause molding in the attic??
So if I’m at home and my ac blows out warmer ac air on a 90 degree day but at night it’s cold. How can I fix that in a situation where my handler is in the attic
excellent but my ac airhandler is downstairs in living room so their is a gap between first and second floor and it's open where my aur handler is so if I close it what do you think it will get rid of moisture on my airhandler it's new ac ..full unit ..
Wish you were in my neighborhood. I have a minisplit ceiling cassette that is sweating
You have insulate when there are more than 20 degrees difference. Thanks for watching.
David, thanks for this vid. When you say the “20 deg difference”, are you speaking of the plenum TD or attic air vs supply air etc? Thanks much!

Have ran into this several times, and it always is in a attic that is very cramped and poorly ventilated.

Did you end up insulating your air handler? If so, did it work?
What material to use to insulate or wrap the outside of the air handler?
I had this situation today. The customer kept the house at 68* and the air handler was in the attic.
What u do about it bro
Yes what did you do?

It's a static pressure issue, duct work is probably too small
Exactly.hes not totally wrong but air flow is man issue of a sweating air handler.
Thanks David! Good stuffs!
66 degree return air😂
Run a fresh air duct to the RA & raise the RA temp..
It is a static pressure issue. We see this when the customers are using high merv rated filters.
Can you apply a reflective insulation on the outside of the air handler that will work?

Bro…l..68 is sweltering. I live in Louisiana. 60 is my happy place
Your systems oversized if you’re able to reach 60 degrees on a hot summer day. Way oversized.

HVAC Xpert too many people are addicted to cool air . Or there may be fat customers
Mine sweating and it’s set to 72-74 at all times. Similar climate in Charlotte, NC. Thinking it’s a poorly ventilated attic 🤷🏼♂️
Chris Moffett I live in charlotte and I’m dealing with the same problem, my tstat is set to 74.

If my air handler is sweating in the attic, can I put insulation material to prevent the sweating??
i had the same problem with one of my costumer and i install one electric fan attic now the system is working fine..
Can you please provide me with a picture?
I think I’m going Through that situation right now the customer seems to like really cold air and I have a 4 ton variable speed Goodman I just installed and it’s sweating like a whore in church🧐
Is this why I have water dripping out my supplies?

The mood won't hurt you. That's a scam.
Call a reputable HVAC man to have it checked.

Simple... Call a reputable HVAC man that knows his trade.
Is that normal to have that air handler on bricks ?
It's not on bricks. It's thick Styrofoam
I would love to work with this guy
my airhandler is wet from outside I don't know what to do
