This guy cut the shroud on his A/C---Good idea?

Its a 15 minute video of him cutting the shroud and installing metal lath. Idea being there is better airflow and therefor better cooling. Feel free to fast forward you wont miss any special tips.

I read some of the comments. Few people disagree and which way the air flows. Several said older units used to be open like this mod. Negative was damage during hail.

    Our Coleman Mach 15 was overheating. Without shroud (Maxxair MaxxTuff) it ran better. So I made a flat "roof" from plastic sheeting.
    Then Chris Bryant pointed out that I needed baffling at the corners of the condenser. Cut a couple from a swim noodle and it ran right again with shroud on.
    A season later it didn't seem quite right. I carry spare capacitors and swapped Compressor Run. Smoother, queter, cooler. Cap tested OK on Fluke and ran the compressor. Go Figure
  • Not sure I would chop a new unit but an older model that is not cooling as well and icing up a bit... what is the harm in that. Alternative is a new upper unit.
  • If i remember it was a guy from Colorado saying he needed hail protection while the trailer is parked. In a way the lath might protect more because of the smaller holes. Assuming its strong enough.

    You know that reflective bubble wrap people put on windows? Think it would help on the inside of the shroud? Good time to add some while the shroud is off.
  • Notice the cutout was on the back of it. I don't see how hail would do much damage there. Driving so that hail would hit the front would not make a difference here. This seems like a good idea.
  • I wonder if smoothing out the backside depressions on the shroud might increase the airflow significantly? It would be less work to simply caulk those depressions, thereby reducing air turbulence while maintaining hail protection.
  • Sorry to be clear about the hail it was the older units with no protection to the fins. They had more airflow but could be damaged.
  • Same here seems like a good plan. I don't get the hail comment tho. If anything the shroud looked to be stronger than the original.
  • I saw this and agreed with how he went about it. Did you see the part where he measures the improved air flow? I would do this with both of mine but I have no issues to date...also I think my shrouds are designed differently.
