Love your vids. Thank you for this. In the SF Bay Area, $600,000 gets you a studio apt with crack dealers and homeless outside. You can move further away and get a house where you will hear gunshots. A house like that here would be $2 mil plus.
Appreciate the video, bud. Looks like you missed the bath fans on the third floor not being hooked up but that’s neither here nor there. What I would do though in your video is talk about the furnace in the attic needing a light, an outlet for servicing, a 30 inch platform in front of the unit, a 24" walking platform from the access opening to the furnace. I’d also talk about the gas piping pressure test needing a minimum of 10 pounds of pressure for at least 15 minutes. The dryer vent, a person could spend 20 minutes going over how that should look. I can’t tell you how many times I’ve seen screws through the connections, the pipe being reversed, homeowners using flex duct buried in the wall…. Thanks again for taking time to shoot this video, I get complacent from time to time when I’m looking at 25 houses a day and just wanted to see how others are doing a mechanical rough in inspection. Respectfully, Greg W.
Wrong idiot, if you were really in the construction trades youd know nobody calls them "bathroom fans". Everyone calls em fart fans. Im a plumber and i know that! lol
HVAC in Michigan is so much different most furnaces are in the basement and all piping in chases between floors is hard pipe and most air boots are mounted in the floor below a window except bathroom boots are mounted in wall away from the water closets ( toilet ) Incase of overflows… pass thru vents above every bedroom door …
Their reasoning is that it could in some way get punctured. They don't allow in Augusta ga and surrounding counties or Aiken county SC and surrounding counties. If we attempt to, they have us tear it out and replace with hard duct
All your videos for inspections are very helpful.! Thank you keep up the good work. Quick question can a bathroom exhaust into the soffit or does it have to exhaust straight up to the roof?
Why is the dryer vent box not sitting lower to.match an actual dryer vent location? All dryer vent boxes have instructions that show the location to be as low as possible to match the dryer and minimize snaking of the flex duct between the dryer and wall box.
Very insightful video. I’m having a 3400sf house built now in Oklahoma City. HVAC rough in starts Monday so I’m checking out videos to help know what to look for. One question I have, why does the dryer vent go down instead of out through the roof? Is it code in ATL? Just thought the path of least resistance might be best and go out through the roof instead of down. I gave you a 👍and also subscribed so I can check out some more of your work. Take care. Steve
Hey Renaldo, A couple quick questions for you. In your duct shafts doesn’t the duct have to both enter and exit the shaft on collars? How would you fire rate a shaft with flex duct? I’m very curious on your thoughts. Thanks for the great video
Hey Ronaldo, I’m actually talking about residential work. In your video I seen that the shaft had a sheet metal top on it but my question is, is there a metal collar going through that sheet metal cap or is it just flex duct. The reason I’m asking is I just became a combination residential inspector here in California and I have seen it done both ways. Is the flex listed to go through a fire penetration? 30 years ago when I used to install HVAC shafts in residential houses we had to use hard pipe and wrap it with insulation. Now that I’m an inspector I see it done both ways. I’m trying to figure out which one is the right way and what the code actually says. I’m not a fan of flex going through the top and bottoms of the shaft because a lot of times I see the duct get pinched. Also times the installer has cut the shaft hole too big for foam expansion insulation to cover and they try to grab pink insulation and shove it in there but you can’t shove it in tight on flex duct because flex collapses. Do you know of a code that addresses this gray area? Thanks for your thoughts, there is a lot of useful information in your videos. 👍🏻
@@PPG1967 I have quick question. How far diagonally do you like to see pvc furnace exhaust away from a window that can open? The manufacturer’s book says 4 feet but I’d like to know what inspectors want.
I dont understand the thought process behind putting furnaces in the attic. What do you do when it needs to be replaced. Cut a hole in the roof and haul it out with a crane?
Do you do voluntary inspections for home renovations? Is there a company I could pay to do one? Sounds weird but I’m about to start my own home renovation and I’m in the sticks and could probably get away with not getting any done pretty easily. But most of the code are there for a reason and I would like to know them. I bought the IRC and NEC books are there any others I should buy. I’ve done everything but raised foundations and roofs. I’ll probably get blasted by some for wanting to skip paying a bunch of people but I’m in no rush to get it done so I’m more than happy to learn to do the things I don’t know how to do and to do it right.

You mentioned pressure tape, I'm in the process of finishing a basement and unused an aluminum tape labeled as general HVAC use for class 1 flex takeoffs and returns. Did I use the right.tape? After taping I also used a heavy duty HVAC zip tie over the taped connection. Am I good with.this install?
Wrong!, mastic is rubberish in my opinion metal tape is better just give it 3 layers and thats it , oh if the elbows or piping has oily from the factory well use some spray glue or cary acetone and a rag to clean each one 🤷♂️
Yes i tried to tell him flex should be only run 5 to 7 feet and he said i was wrong. This guy is a moron. I been doing hvac over 23 years .i never seen so much flex in my life.
Listen to me very carefully.flex duct is only acceptable for so many feet.to use flex duct for your runs going up in a shaft is pathetic,and after 7 feet of flex your cfm capacity is greatly reduced. Flex is great for take offs off trunk, but when i see 86% of the duct in a house all flex it is disgusting. Ask a mechanical engineer if you think i am out of line.thank you, and byw anyone can look up what the cfm is on flex.the more you use the more restriction you have.stop
Sir, there's no max length on a flex duct. These are short runs (residential application not commercial). Typically two units in each house, basement or crawl space and attic.
@@PPG1967 yes there is typically its 5 feet.i think that is a little strict i do 7feet all the time but code depends on size of duct i believe 6 is only allowed 5 feet.just because people been running 15 ft of flex in areas doesn't mean its correct.

Here in Augusta GA
They absolutely do not allow us to run flex in a chase
Really??...why not ??..it's allowed in the code book.
Their reasoning is that it could in some way get punctured. They don't allow in Augusta ga and surrounding counties or Aiken county SC and surrounding counties.
If we attempt to, they have us tear it out and replace with hard duct

Quick question can a bathroom exhaust into the soffit or does it have to exhaust straight up to the roof?
If the soffit is vented (perforated) the bathroom exhaust cannot. Run it up through the roof or the side of a gable wall.
Why is the dryer vent box not sitting lower to.match an actual dryer vent location? All dryer vent boxes have instructions that show the location to be as low as possible to match the dryer and minimize snaking of the flex duct between the dryer and wall box.
Dekalb County Code Ordinance also require saddles to be installed at every 4'. :D just Georgia stuff

It's at the discretion of the mechanical contractor, I'm sure the contractor is going with the shortest run to the exterior.

So, you're referring to more commercial work. You'll rarely find any flex duct on a commercial job, everything is hard duct.
With Residential all you're doing is making sure the top & bottom of a concealed chase is sealed. Most Residential houses use flex duct.
I appreciate your comments ... thanks for watching.

I'm sorry I'm a new homeowner and I want to know does the duct suppose to lay on my attic door where I can't get in
That's a no. It should be supported with straps.
I got failed for not having a ladder for the inspector to use to do his job. What kind ish is that?
Only in Waco Texas
Lol...I've done the same. The Builder or Contractor must provide access.
@@PPG1967 Good to know. I thought inspector was just out to get me. Lol
Doesn’t the exhaust termination for the bathroom need to be greater than 3 ft from an operable window?
It depends on where you are and what code book your state has adopted. Here in Georgia, we use the IRC for residential. 3' is the required clearance.
I’m in coastal SC and we’re using 2021 IRC. Thanks for your videos, I share your vids with other inspectors 👍

Am I good with.this install?
Typically you should use UL-listed 181 pressure tape or mastic at all the seams.
What code book is adopted in your state?
Does the rules apply for a steel frame home?
In what way??
The mechanical rough installation should be no different, regardless of framing material.
600?! That house would cost 800-1m in Wa St, maybe more!
That video was posted about two years ago. That house is probably valued over $1 million now.
Thanks for watching!!
What state are you lo cated
Atlanta, Georgia
Putting foil tape on the metal exhaust vent joints is pure garbage. That is what mastic is for. Mastic will NEVER peel off.
You are wrong!!!... what code book are you referencing sir??
The tape must be UL-181B pressure sensitive tape.
Wrong!, mastic is rubberish in my opinion metal tape is better just give it 3 layers and thats it , oh if the elbows or piping has oily from the factory well use some spray glue or cary acetone and a rag to clean each one 🤷♂️
