How to clean a Air Conditioner/RTU/HVAC condenser coil/Evaporator coil

Nu-Brite is a non-acid, alkaline-based product for cleaning and brightening air cooled condensers. It is formulated with the best available foaming detergents and chelants to quickly penetrate and dissolve greasy dirt and grime and foam it right out of the coil. The safer alternative to acids.

For cleaning and brightening air cooled condensers and other finned heating and cooling coils located outside. It is an alkaline based cleaner that does all that an acid will do without the danger of an acid. Nu-Brite’s state-of-the-art surfactants and cleaners instantly penetrate and lift layers of oily grime and corrosive deposits from the coil. Its foaming action pushes this loosened debris out of hard-to-reach areas restoring equipment to peak efficiency. It is not recommended for indoor use.

Nu-Brite 4X is a new concentrate version available in a ready-to-use quart bottle. One concentrate quart equals one gallon traditional Nu-Brite (at 4:1 dilution use). Nu-Brite 4X takes less space on truck, is easy to carry on roofs, and has cleaner connecting – no more pouring or spilling. The specially developed packaging has a dilution insert assembly; simply use what is needed, cap bottle and use for another job. The product ships as a limited quantity –easier to get to the job site. Nu-Brite 4x requires the Clean Connect Sprayer.

Nice job on the coils. Here’s a tech tip for you. We typically remove the entire roof of the unit. And use the same chemical on the evaporator coil. I know it clearly says not for evaporator coils on the label. But we use 16 oz to one gallon of water mix on the evaporator coils come out like new. Just a tech tip from the Long Island Trane techs.

Seriously, nice to see a pro that cares about his work. Great rinse tool there.

Imagine how many of these units exist across the country...

There is something about cleaning that really sooths the soul. 😁
I'd love it if you could do a comparison at the end, pictures before and after.✌

Great job, on new units with a lot of electronics connecting the neutral to the ground also all current to return back on the ground. This can kill sensitive electrical parts. Works great on older but some newer units can be costly . The vacuuming was definitely an extra step that makes for a really good job.

Great video! I was worried the portablaster wouldn’t be good enough for rooftop units. I just bought one and will be doing my first cleanings. Thanks from Canada!

Good work. HVAC techs expose themselves to many hazards. I would hate to find out what diseases we’ve picked up from exposure. God bless us.

[davebrunson]

Finally a youtuber that cleaned a unit right!

[benjaminwoodward]

I love watching your content man. It’s always very interesting. Keep it up!

[kevinhansen]

Dude the reason the condenser foamed like that when it didn't look that dirty is because it has to be split apart... Even what you cleaned there is a blanket in between the coil

[blackbear]

Very helpful tips. I love the portable garden hose idea with the bucket and pump. thanks for posting! :D

[nicholasbooth]

Great job bro I like how you take the time out to do a professional job service 👍

[txtmodcarlo]

Just a tip blasting with water from the inside out, you will use less water and less effort on rinsing the coils.

Its amazing building owners dont spec out a hose spigot on the roof I cant imagine it would cost that much when they are building the building

[ohchayzee]

I am a power washer for tnt services and I clean the condensers with a power washer. Just the screen though obviously. In the room we go In behind the fans and spray them out. It’s a rush of water into the room too most drains suck. Cool how I learned something new today. Thanks for posting will subscribe

woohoo
wow brother love your work

[Janijauzaa]

Nice videos mate! I use usually in condensers that are outside just high pressure air. In kitchen theres usually grese so yes you need chemicals to clean that. But atleast here in Finland outside condeser contains only dust and dirt. Like i dont see any reason to wash it with chemicals.

I’m getting my EPA soon. Can do a video on superheat and sub cooling and a pump down. On a these unit. It would be so helpful

0:14 If everyone could try to only see the positive things in life the entire world would be a muc better place. That's not an assumption we all know what we are doing when we send out in the universe a negative intentional comment directed at someone that's only trying to be helpful to others. Once everyone is happy and genuinely mindful of others we all will rise up as we are all connected. GREAT VID

Not sure about US installations, but at least here in Europe you should never use ground as a neutral. It will pop the GFCI, disabling multiple if not all circuits in the building. Afaik in the USA they don’t have whole-building GFCI’s but it’s still not a good practice. You should use a proper neutral as neutral 🙂 If the ground is not properly made in the subpanel, you could put the casing of every single device in the building under 115v, which is a big hazard.

If the customer wasn’t willing to pay for an extra guy, to handle a long hose run and booster pump monitoring, we refused the job. We weren’t going to pay for damaging a roof, because the coil cleaner wasn’t throughly diluted and rinsed away, when rinsing the coils. On foaming coil cleaners use a few drops of Calgon De-Foamer, to aid in rinsing the unit out.
