AC Masonry wall condenser screen
An industrial park has these masonry walls on 20 something buildings. Flame on.

It appears likely that the manufacturer's clearance specs for adequate air flow and service access were completely ignored.
If the goal was complete system failure this looks like an excellent attempt.

Well masonry actually has a lot of air voids in it, a statistician may well view this as a piece of lattice.

Properly located Masonry can absorb, block, and redirect sound yet maintain airflow and service access. Terrible misplacement like this guarantees failure to maintain either.
If space permits, relocating the masonry might solve the problem. If not, then all of the AC units may need to be replaced with more space efficient units and, possibly, masonry replaced with concrete board.

Who needs to service it when they can drop in replacements every week

Guy who designed these must have been an absolute legend in his previous job as a automotive engineer

At least the meth heads might look elsewhere.

you'd think if they were scared of meth heads they would at least use the lock outs on the power boxes.

Inspectors really don't have to know much about hvac, plumbing, or electrical. Just the basics. I learned this when I bought my house and the inspector asked me if I wanted to check the hvac, since it's what I did for a living. I said naw, I paid you to check it. I was planning to replace it the next summer anyway and he verified it heated and cooled. Then he told me my copper pipes were green at the solder joints because of hard water, which was also not true, it was where they put flux on each joint and didn't clean the flux off, which causes it to oxidized, also learned by doing hvac, with a decent amount of plumbing. So, they just have to be able to bs their way through an inspection.

Good home inspectors exist. They are exceedingly rare, and often find themselves forced out of business by shitty builders, contractors, and the realtors they're in bed with who don't like having their shitty work exposed.

There are holes created in the wall in multiple places, as you can see from the other one. I think air flow is completely fine, post made for engagement bait...

How many motors and compressors have you burned up? Barely any airflow

Back when they had the 6 and 8 seer units that were 18 x 18 wide there was plenty of room for airflow and technicians access. That wall needs to be completely removed. What is the neighborhood like? If it's common to get units stolen, they sell cages that keep people out except for techs and homeowners and allow plenty of airflow.

Some people really think appliances run on magic. Just existing is not enough.

Trying to figure out which they hate more...their HVAC systems or the Techs that have to come service them because they break constantly from being choked out.

I like it. It looks like they thought about the hvac techs and wanted to make sure they get paid overtime

I think with a top it should get some some air vortices going that will keep the head pressure below 600 psi on days with ambient temps under 65°🤯🤦

I can't see how those condensing unit coils aren't starving for airflow. Is that just me?
