Aaron's got a little rig here. I know. That's, that's, that's your rig. That's Jason's ring he's pretty sweet, and so I never underestimate the visual inspection.

This unit is a 2014 for only four years old and you can see there's a lot of this galvanic corrosion, which isn't necessarily a big deal, because it looks awful that per to file is not terrible, but it's a need of a little wipe down the in See it's got a piston which, whenever I see a unit, that's newer like this. That has a piston. I want to look at what the factory piston is because I want to see if that matches up with the condenser, because if it doesn't the odds that the installing contractor actually put the right sized piston in or pretty much zero. So it's something to look for and when we get the recharge out, it's an easy thing for us to address while we're here if it is, if it doesn't match up so we're gon na check outside and make sure that it's also a sixty seven.

Don't use this toothbrush to brush your teeth. Trust me we're gon na use a little Viper aerosol oil cleaner, and doesn't it's not required to rinse it? I'm gon na rinse it because its evaporator coil, but it's non alkaline non acidic. So it's not going to cause any corrosion. It's not gon na cause any fumes.

So it's perfect for this application. We have light soil, nothing serious, but we want to do this before we clean out the drain pan, because if anything comes off that coil, we want it to go down and out so actually having the vacuum running. While we're doing this is section perfect, so go ahead, that's all you! So now I just got ta. Let it dwell for five minutes or so, and then we can just lense it off right into the pan, careful there's a lot of times those things leak.

This is an ideal sensor. Example. We had a drain pan right underneath this thing, so normally you'd need a drop cloth or something of that nature that divers gon na rinse from the top down and wall to. Hopefully enough see, I kind of liked down with a rag in there.

Just is for up to down motion to get any of the surface soil off without impacting it in, and it looks quite a bit better we're just rinse both sides and we're ready to finish. The drain cleaning and on our merry way.

    Those evap. coils were very easy to access… whats your method of cleaning hard to reach coils …I have a small access panel above a York Diamond 80 furnace… I can barely get a cell phone camera in to take a pic of the inside of that A shaped coil.

    I have a question, hopefully you can guide me in the ride direction. Info before question: I have an HVAC unit and the coil inside the house is set in an angel(My HVAC is 20 years old and so is the coil. Still runs great.). I noticed last night rust/corrosion is staring to build up on the pan that catches the water from the coils that leads to the drain pipe(s) and the bottom of the coil.
    What would you recommend I use to remove the rust that is on the pan and starting to come up the side of the coil?
    I do use the coil cleaner form twice a year and I know they remove dirt, debris, and other junk that gets in to the fins. I am stuck with Google searching how to remove the rust. I do not want to introduce no chemicals (acids, anodes, etc.) without hearing from experts in the HVAC field.
