Painting a Goodman outdoor unit?


Okay, some of you may think this is silly. Quite frankly, it's probably just my OCD kicking in.

A few days ago, I noticed that my Goodman HVAC units outside look like crap. Although I took the time to apply car polish to both systems, the factory paint is badly faded and most of the screws are rusted. The units are only 6 years old, but they do get a lot of sun. I never recall this happening to the Trane I used to have.

I'm considering painting both systems with a comparable Rustoleum spray paint. I'm assuming I'll need to remove all of the metal panels. For those of you in the know, how difficult will that be? Is it simply a matter of unscrewing the panels and laying them out on a sheet of cardboard to be painted or is it more involved than that. I know the tops will be more difficult, but I'm curious about the other parts of the housing.

Perhaps I'm not that silly.

99% chance that if you dismantle that guy and put it back together it will rattle and be louder. also you cannot just paint it in place w/o paint hitting the condenser and plugging it. waste of time and paint IMO. Gman is one of the kings of the builders grade market if you get my drift, not Trane.

I just took a closer look at my Goodman AC units. I think it's possible to paint them WITHOUT completely disassembling them. All I'll need to do is remove the top and place a piece of cardboard in between the side panels and the condenser. Of course I'd have to be very careful and paint it on a very calm day.

And when U do B VERY careful not to disrupt the wiring to the fan motor or break the clip that holds it in place or the wires will get chopped up by the blade. NOT an easy job 2 do for a NewB. Also probably need to add some refrigeration insulation tape between the top and the coil or there is a 99% chance it will vibrate and B noisy. Still wanna try?

Well actually, I have two brand new tops that I picked up a few years ago for $40 each. I've been meaning to install them for the past 2 years or so. I was just waiting for the right time.

As luck would have it, the fan on one of my HVAC systems has developed a wobble, so Goodman is going to replace the motor and fan blade under warranty. The HVAC tech said he would use my new top when he replaces the fan and show me how to remove and reinstall the top so I can replace the top on the second unit.

That's kinda why I'm thinking about painting both units. Timing is everything.

Good catch. I'll make sure I do that.

I understand your need for a nice looking unit however you could be causing problems. For 1 if you do remove many of the screws make sure if you replace them with new ones the same size and length because you could make a hole in the condensing coils. Many of the screws used in manufacture just miss vital parts of the sealed system. I wouldn't mess with it and if I really wanted to repaint it I would leave everything in place and brush paint the metal casings and clean the coil. That's it.

If the top is coming off anyway, I don't see much harm in it.
Just slide some newspaper (not cardboard, coils fins bend if you look at them crosseyed) between the housing and the coil to keep paint off the coil.

Removing the top without damaging the coil by hitting it with the fan is another story.
