MINI SPLIT FAIL - what a bad install looks like
This mini split fail caused MASSIVE WATER DAMAGE and had to be decommissioned after only a few weeks of service. The homeowners were left with a $7k bill....
Mini splits are simple in theory but there's a lot that goes into selecting the right style and size. Equally important, there's a lot that needs to be done to make sure they're working properly. They're more 'single zone hvac system' then they are window unit. It's easy to make them blow cold air. It takes more skill to make them run properly.
These mini splits failed for numerous reasons. This is a bad install. The nail in the coffin was leaking refrigerant, which led to low refrigerant levels, which led to iced up coils, which led to condensate leaking through the house. The most obvious deficiency was the wrong style system being installed. This was an all around mini split fail. What else do you see wrong in this bad mini split install?

What an ALL ELECTRIC TOWNHOUSE looks like!
I've seen plenty of the "SS" clamps RUST and fail.
I really regret pulling down the lath and plaster in my old house......it was built in 1823 after the family lost their wooden house in a fire 😢 the walls to the outside were over 18 inches thick and it was one of 3 stone houses in cape may. From the era. I could tell stories about the place for days but it was a family involved in shipping and they built the place from ballast stones and they were the first family to have central lighting 😮 they had a carbide generator pit that lit the house into the 60s😮because the electric company didn't want to run the wire. My dad preserved the place from the second owner and we even lit the Christmas lights from our acetylene welding bottle for the holidays.......those lines were still good 100 plus years later 😢 god i miss that place and I was screwed out of it by a lying step mother a greedy sister who got hers and it happened when I was overseas fighting 😢
Put free oil tank full of fuel on market place it will be gone by the weekend
Well organized says the guy pointing to crooked wiring
Idk what's worse, that or when I helped tear out the interior of a strip club after it flooded & we found an old condom inside the bathroom wall! 🤮
he flinched when he heard tbat beep
What is the best way to apply just linseed oil on a cedar deck?
People use to take pride in what they did for a living
Shit is good for another 100 years
That condenser gotta be working extra hard with such little clearance around it
Pros use them because they're cheaper. End of story.
I prefer the steel clamps but all my coworkers prefer the crimp rings. (Rings are cheeper)
That was knob and tube 2.0😂 Have been in century old houses where the wires were just bare everywhere😅
I’m an apprentice hungry to learn and I appreciate learning from all your videos!! could you do some videos on Multiwire branch circuits please they’re still confusing to me Thanks! 🙏
Expansion fittings are way better
So what do you do with brick that was already painted? How do you fix this?
That is very interesting!
one of the big disadvantage was knob and tube was never designed to be within insulated walls. It used the open air to dissipate heat and when people started insulating that he didn't dissipate anymore. And then later rather than getting removed people come in and retrofit all sorts of nonsense which can really overloaded. We used to do things better.
So true and my old house was 18-20 inches of stone walls... .it managed temperature and was before installation and the technology was perfect for the time.....but when things got cheaper and installation is needed. The craftsmanship was just lost 😢
Real wood there. At my city, if this wireing is in good shape. It's allowed. Box though has to be at least a pushomatic. Some just ran a separate ground alongside.
Wow... smh
0 it's mint
$50 gift certificate incoming!!!
I’m here for the music in the back round. Tight work boys. I’m a fan of the vertical screws as well and why is it white guys are the best as ⚡️ work.
Insurance companies today want it gone. If your buying a house that has it, no insurance for you till it’s gone
Gotta be thankful that it can be alot worse with wires an hoses in the actual walkway.
Obviously the contractors are at fault for the work quality 😂 but customer should've done research on company before signing a check:/ Sucks there's people out there giving installers and service techs a bad rep by scamming customers with dookie work.
City people are wild.
Craigslist, free offroad diesel. A scrapper will take that tank for free.
Amazing old school work!
I feel like this guy was tasked to handle this issue in the most expensive way possible. Why remove the tank in the first place? Even with gas it’s a great backup fuel source for your HVAC?
When you get to a certain level? You can’t cowboy these things out and still maintain good standing with municipalities and banks. They’re document med as deficient and need remediation reports to close out permits and get financing. The boilers have been out of commission for 8 years and would cost $4 grand to get back running, and we’re moving walls so the current radiators will be obsolete.
The high def really shows all the sweat 🥵
That's AZEK fascia, right? Do you know if there's a similar hidden fastener system for cedar fascia?
They def make cedar plugs. They’re not as easy as the azek system though. A combo of Ss nails and trim heads usually work pretty well for us for cedar
@@GreenBuildingNetwork Thanks!
What is the product your using under the fascia ?
Cedar Breather by Benjamin Obdyke! we had some left over from a shingle job.
Probably nearly 1000 histroic homes, and this is the only time ive seen it look "clean" usually i say thank god its not build the same as the historix homss
FYI... Most insurers wouldn't insure you if you have any knob and tube in the house. Even if its disconnected. They might even reject any insurance claims if there's a fire.
All them holes were hand drilled too!
The thing that scares me most about knob and tube is learning about how later on when people add onto the electrical they often tap random neutrals creating a very high likelihood of a neutral overloaded when a hot may not be.
Now go change that f****** smoke detector battery
And in the meantime you hear the smoke detector chirping in the background because nobody's willing to change the battery amazing.
bruv, it's a vacant building that we haven't broken ground on yet!
Beep
That knob and tube is not properly run. It wires were suppose to be run so that if one broke it wouldn't be able to touch the next wire over. Now imagine having to pull a soldering iron out a fire and then running back inside, climbing into the attic, and making up your connections.
Beep
bro about to build another paris
At those sorts of prices, if the heater still works, use up the left over oil over the winter, and have the specialists work with the empty tank. I am Green AF but im not willing to let the perfect be the enemy of the adequate
That's a really nice find. Beautiful example of old wiring.
It's backwards 😂. Stickers supposed to be on back
lol I can assure you they're not on backwards
im so tired of red tape and bs leave us the hell alone id rather live in mexico at this point and be free but have corruption here the corruption is red tape.
Meh - flip side to that is people leave these tanks buried or dump oil down the drain. It’s annoying but waste oil can be pretty burdensome. This happens in restaurants - companies charge to take waste fryer oil, filter it, and sell it as biodiesel
Are you certified to do this stuff? Why do you need a permit to do this!
We are not certified to remove, it does fall under our building permit. It was a permitted install so for it to be removed from insurance policies and records, it needs to be documented. If we didn’t have a building permit, we might be able to get away without a permit. On the flip side, if there’s a spill, we’d be liable!
It's diesel fuel. Suck out the top 1/2 tank and mix with your diesel machinery. That's what the company is going to do with it.
I know. It kills me that they sell it and charge to take it. Almost all of our tools are Milwaukee :(
@GreenBuildingNetwork so use the Milwaukee m18 transfer pump.... Pump it into drums outside and then use it somewhere that needs oil for heat. Or in diesel engine... Those companies gonna do same thing! 2 bucks a gal to resell it it at market price??? Smh Pump it, get a scrapper come a remove it free... Remove fill pipe and vent pipes, or at very least, cap from outside and then remove pipe inside as close to wall as possible and cap in inside as well.
@@johnmaranuk1842 The last time I lived in Germany, many people had diesel heat and cars. It was illegal, but everyone put some of their heating "oil" into their car. The police didn't check either.
Charging you $2 a gallon to take your good fuel oil is the real crime.
Ye, depending on how much free time this guy has, he could probably just pump the stuff out himself and sell the oil
I know! The double dippers!
If we had time or appetite for risk we def could
Jiffy lube takes it for free, and recyclers will pay you for it
