That’s pretty bad shape for a 12 year old Coleman style York unit. Yes, someone definitely overcharged those microchannel coils to try and get that suction pressure up. Yes, that evaporator needs to be replaced. Yes, you should quote them a new unit. Yes, you should tell them if this is a result of the fact that they never had their equipment maintained properly. When I find a unit like that, I tell them what the options are, and I tell him that the likelihood of success is going to be low when you have an evaporator that has fins literally falling off of the coils. Typically they say, “try to get it working,” and I say “yes, but it’s not going to work as intended, which means you may get 30 or 40% of the cooling capacity for your space.”
That's what I do. Proper charge, clean coils, check fans, walk away. "That's as good as its gonna get, mister" In this case, fire dampers were tripped.
When i clean coils, I clean the drain line and pan first after the brush down. Before the chemical you should wet the coil. This allows the chemical to stick better. Also you should go bottom up. This allows a clear path for the dirt to go. FYI them United chemical eat coils especially if not rinsed off.
Man you’re going to get the engineering department fire from that place ,looks like they aren’t doing their jobs you’re fixing all there HVAC equipment 👏👏
It wouldn't be too hard to make a cordless pump like that. There are plenty of DC diaphragm pumps which will go up to 140 psi and even more. Ever thought about a battery operated chemical sprayer?

The tech with many talents jmt made it look easy
Good job Jumper.
Thank you John!!🔧⚡️

Good work! It pays to be patient
Great interesting and helpful video !
Well explained. Thanks for sharing w us.
Good job jumper, I do some jobs like that at work...I am new to your channel....greetings from boiler operator from north jersey...love your channel
Loving your videos man!
Excellent work!
Good work 👍👍👍
Great Video. Thank you for sharing
What was making the coil fins decay that way??
The worst ones are the ones you have to split and clean. I almost never use coil cleaner unless it’s really bad like that one.
You do great work
Great Job
Man those engineers really didn't make that coil easily serviceable for technicians lmao smh!

That coil is seriously flat
