Air conditioner mod?
I recently saw a ytube vid on cutting out the plastic "grill" on the fan output side of the condenser and replacing it with metal lath to improve air flow and thus improving the efficiency of the air ...

Yes, increasing air flow across the coil will reduce head pressure, thus reduce suction pressure making the air colder, to a point. I'd like to see accurate before/after air flow readings, not "modeled" with a little 12 volt fan. CFM and static pressure (that's the pressure loss across the louvers he's reducing) are not a linear relationship. The proof really is in the reduction of head pressure and there is no before/after reading.
I found a big installation error on my last rig and this reminds me to check this one. When they installed the ducted conversion on my last one they did not seal the supply and return plenums properly, meaning a lot of air was just short cycling between supply and return, not getting to the space. Took some foil tape and sealed between the two plenums and it helped A LOT!
Not an A/C "spurt" by any means, but your first point makes sense and one needs the actual facts and not just "seat of the pants" WAGS. As to the second one, that IMO is probably much more common and I have heard of issues concerning the poor sealing of the supply plenum both to the ducts and between it and the return plenum.
