AC techs are typically useless. They know how to install things. That’s about it. They don’t know how things do why they do.

Great video and VERY informative. I've got ducts in the attic; I've got to check them out. Thanks!

Thanks for the video. I live in Florida and thought it might be helpful to reinsulate the duct work. What spray insulation would you recommend? Can this be a Do It Yourself type project?

Spray Foam is good for air sealing. The problem however is when spraying duct work, most of the time you can only get to three sides of the duct. If the bottom is not insulated you create moisture or condensation problems. These problems are hard to find until the ceilings in the hose star showing signs of wetness or staining.

I'm going to explain my issue with ducting in the attic. I have only electric heat in the house and had central air installed with the air handler and ducting in the attic. During the frigid Wisconsin winters heat rises from inside the home in to the ducting and air handler, hits the extremely cold air, and creates massive amounts of condensation. Enough condensation pooled up inside the insulation sleeves of the flexible ducting that it began sagging and eventually started dripping from the garage ceiling and down walls in the house. This happens even with the registers closed. I had to seal them off with plastic which helped a little. Spring time came, I pulled the air filter out and it was a big, wet moldy sponge. So I have to go through and clean out the mold, "fog" the ducting, and most importantly, have the ducting spray foamed and sealed tight. The air handler needs to somehow remain warm in winter as well. I've had to educate every HVAC guy that came to look at this A/C on the problem. Also, I have not located a single duct cleaning biz in Western Wisconsin that is capable of cleaning this type of setup. It's been a headache.

Got one duct vent not blowing air . while I was doing some other work looked at my vents to see any disconnect loose or damaged ducts but really seemed fine . Hmmm going up there to take a closer look .

Excellent video. I think the A/C repair guy did something to my attic duct or evaporator unit, I smell odor from the attic.

I know I've got the main feed crushed. I can see the dents. And yep, it's in the eves of the knee wall. Suggestions on how to check the duct work throughout the rest of the house?

Spray foam is almost like a permanent compromise, so you better make sure that the attic venting setup is what you want for the life of the home. Unfortunately, a lot of these types of homes also have a horizontal furnace in the attic as well, which is a whole other problem altogether.

Naples Florida here 😁 We’re getting nasty rafter attic smell being pushed through the recessed kitchen lighting fixtures and wall light switch plate / pocket door near kitchen when AC is running. Thinking we have a ruptured duct. Problem is that there’s an attic door in garage and master bedroom closet at the opposite side of villa. Garage access will not provide an easy look-see to troubleshoot. Are villa attics easy to crawl through? Any advice would be appreciated. Great video btw

Ok you just explained the heat in the summer but is it the same principle but vice versa in the winter!

In my house ducts go through attic but they are insulaited with 50mm of stone wool and covered with plown stone wool. And ducts are only for supply and return air, heating is done with fireplace, heatpump and floor heating and cooling is done with heatpump

Homes of the future sure won't have ducts in unconditioned spaces.. because we're starting to realize that insulating the *roof* is a much cheaper and more effective strategy than insulating the ceiling. Turns out, keeping a crazy hot box on top of the cool box you live in is a terrible strategy for keeping the costs down.

@@jamesbizs Incorrect, what you are thinking of is swamp cooling which cools by removing humidity. AC works regardless of humidity but in high humidity situations they also dehumidify as a consequence of condensation that occurs whilst cooling down the air, but the dehumidification is not the cause of cooling the air.

A mini split is the answer much more efficient.

You should install screen over the ventilation vents to keep the ducks out.

12 years ago, and we still haven't adopted these simple practices yet. How ridiculous, especially considering the amount of energy that is lost.

Sir, I have concern right now. A technician drilled 6 holes in the filter rack and my unit is also in the attic. He told me no air in the attic nor fiber glass will get into it but I begged the differ and he put tapes on those holes saying these tapes are for AC units and they last many years. But he missed one hole and after several month I found it today. I hope no bad air nor fiber glass came through. The problem is my filter doesn't fit too well inside the filter rack due to filter rack not made correctly. Also those tapes are coming off as well so I had to put extra. Other AC companies told me that "Yes, air in the attic will get through those holes." Also told me those tapes are not going to hold for too long. Do I need to be worried? I have kids in the house and I am freaking out because one of the hole wasn't taped. And the warranty company can change the filter track to new but they won't do it because they don't want to cause more issues because they said once you take things apart and install new because you already took things apart it won't be the same. And things will fall apart and get loose. So tape is the best way to go with along with some seals to seal the tape so it won't come off. But is that the best way sir?

is it safe to use mastic duck sealant inside the filter rack? our technician accidentally made many holes on the filter rack so he taped them and some part he couldn't tape because it was in some odd places it couldn't be reached, but he used mastic sealant to cover the tapes and the holes. But he used them a lot. Like close to 1/2 inside the filter rack. Are these safe?

Can you over insulate the return? My 1 ton ac unit is in the attic (Va) my return has insulation on it but can I put more?? Will it help? I'm going to put insulation on the lines running from the return. I hope I asked the question right! Tank you for making these!!!!!!

How do you seal the bottom side of the duct work that rest on the ceiling ?

I have an old Florida (1940-50s) home with sheet metal roofing directly on cedar batten ( old school, good thick rough sawn) 1x4 boards. No sheathing or insulation. Should I add insulation panels or spray foam. I'm also concerned about possible condensation though I've never seen any indication of it. That's in addition to the ductwork Identical to what's in the video.

I have high static pressure on a new 3.5 ton heat pump. I know for sure the flex duct is the issue. I have two 12" coming out of the supply in opposite directions. I know I need an 18" for a 3.5 ton heat pump. I did a diagram layout of the duct in the attic. What would happen if I just replace the two 12" to 18"? Ignoring the downstairs, because everything is between the walls. The problem was even worse with an undersized return. The original and only return was a 24x18. The total static pressure on the unit was .9 W.C. I was able to drop the TESP to .66 by making the return 30x24. Since there is so much static pressure and the unit TESP is a .2 and I need an 18" for a 3.5 ton for 1400 CFM. How big does the supply plenum should be and what shape? Should the supply plenum split to 3 18" going out to each of the 3 distribution boxes? Do the other three distribution boxes also need to be larger? Looking at the triangle shaped supply plenum I have very little room up for a rectangle plenum. I think a 3 feet ductboard supply plenum should work. There is a foot from the Air handler to the ceiling and I think 2 feet from the attic floor to the roof. Now I am looking at two types of designs. Design #1 keeps the 18" ducts straight by having a single 18" coming out of the supply and then a distribution box splitting it to three 18". The sides would be coming out straight to the to side boxes and one going to the third box with a slight curve. Design #2 splits to three right at the supply plenum and goes to each box individually, but all three will have a slight curve. I will not be using any metal plenums..... it will be all flex duct and ductboard boxes, because of budget. I am not trying to make a perfect system, but trying to remove the restriction from the 12" undersized ducts installed and replacing the flex duct that was patched with mastic with new ones. Another question about the installation..... I have the flex duct running up and strapped to the roof for support. Since the supply plenum is low to the floor due to the roof..... Can the flex duct be run on the attic floor? Can you tell me which layout makes more sense and less restrictive? Thank you.

When spraying the foam insulation, you can't get underneath the installed ducting.

What about rectifying those ducts that develop kinks in the line? we have hanging ducts in our attics and I have seen numerous times where the straps holding the ducts up either collapse or cause a bend/kink. Would it be worth the money to install an attic fan to blow out the hot air? Or use radiant barrier or high performance foam that is sprayed on the back side of the roof?

He ain’t going to answer you unless you hire him. How to make your attic cooler, that’s the real question then all problems are solved. White shingles number one easiest way unless you live in a HOA run by morons which require a nice dark gray roof. 2nd choice a metal roof that’s reflective or has a reflective barrier under it (again, HOA morons). 3rd, insulate the under side but access to all that after the house is built might not be possible. Lenar morons hung my ducts pretty high up in spots that obviously they could have ran closer to the bottom so more hot air can radiate into them. I have a 8 to 10 degree rise in temp from air handler output to the furthest room ( one story 2000 foot home) on a late day summer day. I also have returns from most rooms so more spaghetti to absorb hot attic air. I wanted to explore if adding another layer of insulation around the ducts bring cold air to the furthest rooms and seal the ends to prevent condensation would help lower the temp. Anything might be better then nothing, but I’m not a doctor just another victim of builders doing stupid sh@t.

is there a video of how you built a flat walking system in the attic out of laminate board? how thick were the boards? My roof has all sorts of support beams that make it difficult to walk through and having only joist beams make it even worse.

I live in a 5 floor split level which was built in the 1950s. And the only floor that doesn't get cool is the top floor. I may have to have another vent put up there, it only has one.

So I was thinking if I go inside the attic and I remove that duct from the plenum and close that circle hole with a board of insulation, would it save me money on electricity since the air is not escaping anymore? Or would the ac work harder because now the air from the rest of the day f the house have to travel farther to cool that room now? I’m confused what to do. Please help me understand this. Thank you

Probably a problem with the vapor barrier in your house. As KPK team said, warm air is mixing with the cold air somewhere, and it's causing it to condense somewhere. Couple of things to consider: How humid is the inside air? Relative humidity over 35% (or even lower in very cold areas) will cause condensation in your ducts as the air cools (insulation only slows the cooling, it doesn't stop it). Is your vapor barrier intact and installed correctly? If warm, humid air leaks into the attic, it will cause all kinds of mold problems over time. Is your vapor barrier intact around your outlets and ceiling light fixtures? Is it intact around your ductwork? I'd seriously consider solutions to dehumidify your house if your home's relative humidity is over 35%. If you have a whole house humidifier because you're in an arid area, do not run it during the cold season.

They really struggle in cold weather, as the condensate often freezes the coils and an electric heating coil must be run to keep the coils in service. Either you're spending a hell of a lot of money to keep the condenser warm enough to operate, or you're going to be cold. If you have sloped ceilings, don't bother with a mini-split heat pump. Sloped ceilings don't work with ductless systems, so you have to get "mini-duct" systems which are only slightly better than central air.

Is this what HVAC techs do?

karl not just this.they troubleshoot issues with furnaces and acs a majority of the time.

Ducks and attics.

Where's your attic venting.Use aluminum tape and mastic

I prefer to keep my ducks in my pond

This is why mini splits are superior to ducted AC systems.. houses of the future won't have ducts at all

In the perfect world ducts would not be in attics but we're not in a perfect world.

or Duct running under these home in Historic Springfield , Jacksonville , Florida that have been remolded and are price at 300k and up , what a Joke.

It's a problem because it costs a fortune to fix. And nobody wants to work in an attic

Did you know? Larry's boastful and bombastic little subtexts make him come across as a bit arrogant... But it's cool, thanks for the tips Mr. Dr. Energy Saver!

This guy has no idea what the hell he’s talking about

blah blah blah blah blah absolutely nothing accomplished by anything you said no valuable information simple solution by your own admission the attic is a hostile environment and in the future air conditioners will be in a conditioned space simple solution convert the existing hostile environment into a conditioned space by applying spray foam to the entire underside of the roof done properly you are going to cut the temperature in the in the Attic from 130 plus degrees down to 70 maybe 80 degrees problem solved have a good day

Yes, foam.. You think there might be any considerations on the overall bldg science? Which foam, what effects of moving the insulation to the roof, condensation etc? The answers are not as cut and dried as you would think, but hey, it's easy to criticize and HVAC people don't have to think about how the rest of the buillding works.

for the foam to work you would have to seal the entire attic including the eves and add a run in the attic to condition it.
