Today I want to do a little video show my process clean in place like a slant, coil easy to access, and I also want to show one of my favorite cleaners demonstrate how that works. This right here is made by refrigeration technologies. It's expanding foam cleaner and I like it because it has high force beam that shoots straight in between the coils and then in expands from that point. So it pushes the dirt out.
It's a degreaser, so restaurant applications like small refrigeration stuff, where you have condenser coils - that just get slam dirty. It's real helpful for that, but today I am doing an evaporator coil on a 2-ton really easily accessible. So I want to show you how well this works. So let me take you inside show you how dirty this coil is and my process when I'm doing a cleaning place, yep it's dirty.
Okay, piston system, plant, coil units, thirteen years old. This is a clean in place application, not a coil. I want to try to cut out yeah, that's pretty dirty, so this should be perfect application for clean in place. You have a slant, coil, it's accessible and service.
Half of what we do is clean. So it's really helped me to keep all my cleaners and a container organized helps me stay motivated to clean exactly when they need to see how sharp this pinpoint in just pushes its way with high pressure between the fins also makes it really easy to use to Get it right where you want it, you see like that, it builds up, gets in your way, start overlapping yourself right here. After about a minute of it sitting on, you just see the dirt working its way out a couple minutes later whole evap sprayed. Now there you go five minutes, you just see the dirt boozing out from between the fins.
This just happens to be a favorite tool of mine feuds on evaporator coils soft enough not to damage the soil. Now I'm just pulling out as much as I can, with the shop back. Everything that's been loosened up by the cleaner by the brush. Pulling all out - and next thing I'll be doing - is rinsing the coil with water, I'm gon na make as much room as I can for myself when I'm doing this cleaning just completely saturate the coil pouring from above and using the shot back on the bottom side.
Pulling that water, through at a high force this usually the longest portion of my cleaning, spend the most time doing this. I like using the pump little pressure I can get in if it's tighter access, the coil has been cleaned. Much better finish things off: I'm gon na go ahead and put C back green push yourself wrench, and I can leave that on the coil. We're gon na.
Do that we'll spray that coil down pan I'm gon na leave this. So I got it. Drainage stays cleaner. Longer this is a slow, dissolve, string, pan treatment, I'm in that pan top edge of that coil.
Any homemade solution recipes . Coke and orange citrus maybe?
Kinda crazy but I have never been offered this by the service man. I’ve done the outside n the a coil is next. The vids on u tube r a blessing !!
Really impressive cleaning. Lots of good advice sir. Thank you
I would have liked to see the kind of unit it was. Are you in Orleans ?
Pride in workmanship. It's a dying quality. For an hours labor, he saves the customer money both today and everyday that system runs.
Great job!! There is no way in hell any of the lazy ass technicians that have been to my house would EVER do that complete of a job. They would rather try to sell me a whole new system. Good grief!
Great tips! I also find it helpful to have my shop vac hooked up & on at the condensate exit throughout the hole process. That way all debris is flushed & then I usually flush the line before I leave customers house. NO CALLBACKS!
Suggestion: Operational data points before with clogged coil and after with clean coil. How much was improved with amp draw, temp split, static pressure, if anything? Thanks for showing how its done.
Brand new …nice attention to detail!
Nice use of the shop vac to pull the water in. I always find myself buying a new wet/dry vac every 1 to years cause we use them in this field so often Service area Barrhaven??
Nice work I all ways learn something new from your vids
nice video.
Man, our hvac life is hard! Thanks for the video.
I didn't think the chemical spray would work for mine so I used my airless paint sprayer without a gun tip. It probably does 2000psi and because the surface tension of water and the spacing of the coil fins, it didn't make any mess of water, It all ran down the coil into the condensate drain to be pumped out.
