Welcome! Here are some tips for using this forum.
Why do Trane, Ruud, Goodman, etc. put those horrible covers on their A/C compressors?
It makes it impossible to check, much less clean, the cooling fins.
I think Goodman calls theirs an acoustic cover - which makes sense since once the compressor burns out from trying to shed heat through a thick layer of dandelion, milkweed, and cottonwood seeds, it gets downright silent.
I have a 30 year old weather king unit that I can check with a glance and clean with a shop vac in about 3 minutes.
The 4 year old Ruud sitting next to it requires the removal of 34 screws of differing lengths just to check whether or not the unit's clogged.
Why are they designed that way? Is it so they'll burn out and the company can sell another unit? During cottonwood season I sometimes have to clean off the units twice in a week. You can't even check the Ruud, and I've seen almost all of the alternatives using the same awful design (weather king was bought out by Rheem and now uses the same horrible case design).
Is MrCool the only one left making a coil guard that doesn't block easy inspection? It seems to be a pretty marginal company in terms of size and options, but it's better than something that runs at about 2 SEER because the coil is blocked.
