Part of my prior consulting jobs was evaluating crawlspaces such as this.OK - so sealing our crawlspace/basement and discover mold (not the nasty black stuff) in the plenums (junction box that the lines come off of) for the HVAC when they installed vents to condition the crawlspace. Now looking at replacing all of the ductwork - which is fully accessible but damn not cheap. These plenums have that felt looking liner on the inside - seems like a moronic design unless you are looking for a prime breeding ground for shit. With the basement sealed and conditioned - moisture that contributed to the problem should be fixed right? Also what is the point of insulating the new ductwork (recommending metal instead of flex that is currently all over the place) since the space will be conditioned now?
Any HVAC gurus on board to help me get comfortable with where I need to spend my money here? Any chance replacing the plenums is enough since the flex ducts are lined in plastic and (hopefully) not as disgusting?

1. regarding the mold... if its small clean it and be done with it or replace the affected piece. If it has the insulation/felt on the inside, get rid of it all IMO. Cant clean that properly or effectively and there is no way to determine the extent of the problem by looks alone. Don't listen to people say they can clean it. They cant. I used to test for it and it never is as clean as they promise.
2. Living where we live, crawl spaces are tough to seal completely. I assume they are wrapping all the structure and walls with heavy plastic and sealing all openings? If so are they going to condition this space? If yes then you dont need insulated ducts as long as the space is conditioned. The HVAC guys should probably install a duct into the space to condition it to a certain degree.
This site is amazing -reps.
Yes - retrenching foundation French drain, gravel over and heavy plastic and insulation up the walls, sealing everything. They install a fan with the drain system such that they circulate air under the plastic and vent to the outside so the plastic isn't just covering crap but crap is not accumulating - supposedly radon remediation system but works to keep mustiness/moisture down. They had poked a vent into each plenum to condition the space which we could look in and see the nasty.
Sounds like we get rid of any felt lined stuff and let the rest ride as far as HVAC work. Should more than cut the bill in half.
Try and match the color with caulk. Paint over the caulk if it the color doesn't match up.
Look around friend's houses and you'll see the same thing. Joints opening up due to shrinkage are common. We tend to notice it more in our own place than in other's. Human nature.
The switch / outlets stand out. If you're comfortable replacing them, I'd do so with white.

Agree. I have an electrician coming out in 2 weeks and am going to ask him to do this as well. I notice it everytime I go in there.
There is also wood putty that you use to fill that crack and paint to match as well.
agree with Cack. Don't use caulk. Sink a couple finish nails on both sides, and use white wood putty over the nail holes and crack. Will sand to an almost perfect finish. If you use caulk, the caulk will likely shrink, crack, or discolor over time. The putty may crack at some point if you don't work it in well, so use the putty knife to work it in deep, let dry, and then put on a second topical coat.... then sand.
Yes. Google white wood putty. Purchase for less than $5. Follow directions. Good to go.

Sounds like a good plan. That system is very effective in crawl spaces here where we have groundwater at like 2 feet below grade and very soggy soils year round.
Definitely consider new ducts throughout. Possibly inquire further into how they handle relative humidity through out the year. Could be a problem of condensation forming on the underside of the floor above if they dont seal it or you keep the house way cooler relative to the crawl space/insulation barrier during summer. Maybe put the fan on a humidistat? Justt spitballing. They should be able to answer that for you.
Also ask about how they allow for termite inspections. This has been an issue for termite inspectors to do their job properly/efficiently and they hate it.
Very cool they are insulating the perimeter walls. Bonus points there.
FTR this is a way more efficient system since most losses in heat pump systems are via duct losses. In your current situation the duct loss dumps cool air into the crawl space causing moisture to develop. This system the air loss will simply be recirculated within the space with no moisture accumulation. Win-win.
If you want to go the extra mile, get a dehumidfier on a humidistat for the crawl space. It should work independently of the air supply. Possibly expensive and possibly something they can add inline as well. That would be primo though.
I evidently suck at Google today. I can't find what I'm looking for so need help here:
Mom-n-law is updating to a "smart house" with Echo, lights, botvac, etc. In search of home security that is compatible with Echo. Features must include: wireless cameras (indoor and outdoor), door/window sensors, touch screen display base for viewing cameras, communicates with smart locks on doors, no subscription service mandatory, communicates with smart smoke detectors.
I'm assuming this exists. Where can I find one?
Edit: Just came across the ADT Pulse system. Aside from the subscription for monitoring, this might be exactly what she's looking for.
Recent PIA - bought an outdoor smart plug a few months ago, didn't realize it needed its own f-ing router/system or whatever. Get 3 Echos for Christmas - $5 smart plug with each one on Amazon. Set it all up in an hour and no problem. Now can't find a damn outdoor version of that smart plug. Getting rid of the original - no reason this shouldn't be able to integrate like the others.
Wifey also wants cameras and shit. I feel a bit too 1984 about it. Sounds like a lot of people that get these end up turning off the motion notices after getting a hundred notices a day for every leaf that blows by. Doesn't that defeat the purpose?

Searching youtube vids now and I came across an action tile website that works with the smart things hub. Add a iWalldock and ipad and the action tile app and so far it seems to be pretty straight forward. But yea, the camera system is still causing me an issue as I can't find anything that just bluntly tells you what to buy and how to hook it up.
Echo, echo dot and the lights were so simple. That's as far as we got though.
So you have a hub? We just have Alexa and Kasa apps right now - and works but lacks some more robust functionality. For example, I set landscape lights to a scheduled time but cannot have it automatically change the time for sunset.
Don't want to have to get a damn hub and lacking motivation to research what can be done with and without one. Also imagine Alexa app will get better over time - why not wait for the tech to catch up?
