    Nice video and good knowledge and explanation

    I finally have found what the heck this slime is. I just figured it was some kind of algae. Is there recommendation for how to regulate/treat to this in a window A/C unit? Unfortunately this window unit is on the second floor. If it was on the first floor I would use coil cleaner and house it down. But so far what I have been doing is using a hose sprayer and filling it with vinegar and then spraying the A/C from down below. Anything else you can recommend?

    Very intelligent and informative insight. Well spoken.

    It clogs the drain and causes to overfill and leak all over and into our carpet. Very frustrating.

    I have no practical experience with aluminum ac coils, but I would be concerned about causing premature failure of the coil by creating galvanic corrosion of the aluminum coil especially if the copper comes in direct contact with the coil.

    Is this stuff dangerous?

    Awesome ideas. We could cut old copper lines into French fries for placing into drain pans so there's no way it could block liquid flow.

    I’m back. Static pressure makes it a lot worse as well as you can’t pitch the whole way it Hass to be very aggressive pitch like half inch per foot. Also no standing water need to front pitch everything not to the point where it spills over the coil but no standing water in the coil pan. As well as maintenance every four months at least. Six months don’t cut it anymore. Well there you have it folks do UV lights in the air purification the good filters they barely work

    Amazing talented actor. A great loss.

    I am still waiting for some tabs. But for the moment, I gave my air conditioner a dose of mouthwash. That shrivelled up and killed any goo that I was not able to reach without having to disassemble the air conditioner. I just recalled that I also have a bottle of old copper pennies. Hmmm. Finally, a better place to put them.

    I will use an electric Copperwire and Twist and Flat them they have More Surface Area

    How about a condenation drain pan treatment pad?

    I wonder how baking soda would help. Chemistry

    There’s no study because they don’t want to class action lawsuit because they’re designing the coils like shit they already leak like a sieve let alone the callbacks for the drain lines and flood damage

    The oil too, need to clean coil on new units or replacement coils , airflow pitch and source like he said . Duct clean and uvc light . We also see it on some copper coils too but not as bad. I’m sure Florida is the breeding grounds for the Zooglea. I did the copper thing it didn’t work that good I even tried brazing rods

    Here in south Texas it has been a BAD year for backed-up drains and drain gunk.

    Have been partial to getting the customer to add vinegar to the pan through the secondary (where I'll usually add a 90 and a cap) – will have to try the silver and copper trick on some aluminium coils.

    I would throw some old penny’s in. My new AC is aluminum, so I’ll watch for it.

    We see this every single day even hundreds of times a year and we’re in South Florida the AC runs year-round never stop we have three days of heat. Customers have to have clean ducts, pretty good filters changed often UVC light in every coil literally as well as Remi halo air purification. And we best go out every four months to do maintenance are we going to have issues still. Unbelievable been getting worse and worse. It is very rare to see it on the copper coil. Aluminum coils all day every day. I have some apartment complexes that I stack 20 blue tabs in the back of the coil every maintenance and hope they last a few weeks. We also install the time release drain strips they may be helping a little bit but it’s hard to say it never stops. We have to coil clean and acid clean drain lines constantly. The static pressure in the variable speed technology most likely doesn’t help. Thanks Jerry

    I’ve read some places in Texas and in Florida where they are doing light coil cleans on every coil they install and on every new install and they have pretty much cut down dramatically on the that issue

    "It's not a silver bullet, but if you DID have a silver bullet you could put it in the drain pan." – best quote.

    Dame I’ve seen this twice in the field the senior tech thought it was oil mixing with water and condemned the coil
