I know some companies offer 90-day returns etc, but what item would you think everyone would benefit from if it was an industry standard to have a test drive like new cars?

My nitpick would be microwaves. I have tried picking out what I thought was decent microwaves in the past but it's hard to know exactly how it functions without using it. For instance, my microwave has an express button (30 seconds) or a minute plus button. You can only use one of them, if you've hit the minute button the express button doesn't let you add 30 seconds while it's active and vice versa. Also the beeping, even if you hit the stop button and open the door when it gets to 0 seconds, it still goes through it's "I'm done" beeping which is loud and repetitive making you stop it at 1 second and still having to click cancel which makes noise. So what's your choice?

The grow tent was mostly self-contained and humidity-controlled and monitored inside and out. It actually had to be indoors because of our short growing season, risk of germination from nearby industrial crops, and federal licensing requirements for the type of plant at the time. Regardless, the HVAC experts were here on-site and they could have opened their eyes to what I was telling them. There's was no heat load calculation. They said "this is the unit we install for your type of house and it's more than enough. Trust me, I've been doing this for..." etc. etc.

Of course condensers and evaporator coils work by pushing entropy around. I'm not sure what in my comment would have led you to believe I thought otherwise.

Short cycling would be a happy problem at this point. Over the past month the shortest cycle was on a 16 C day, when the A/C ran from 6:41am to 9:15am, and the longest were on those 32 C days when it started at roughly 7:45am and didn't finish cooling until 5am the next day. You suggest that it won't do anything on a hot day, but the temperature gradient indoors when the outside temperature is high is measurably lower when the system is cooling as compared to idle.

Maybe the HVAC guy was thinking I was just one of those same customers you're complaining about. Nobody's asking for a system ridiculously overpowered -- Just properly powered. I understand the value of properly sizing a system. For instance, I know that a properly-sized furnace should run nonstop on the coldest day of the year. I also know that you don't have an entire month's worth of "coldest day of the year"

My house can be 60 degree warmer than the outside temperature in the winter, so I just have to point the blame somewhere when it can't stay 10 degree cooler than the outside throughout summer. And yes, I know cooling is a lot more complex than heating, but I'm giving the A/C a 50 degree headstart.

...And that is why I think there should be a trial period for HVAC systems.

Realize no system can overcome improper ducting sizing. It’s very possible the original design is the bottleneck. You adding a massive amount of heat and moisture is just exasperating the issue. You’ve got a unique setup. What it sounds like is that the HVAC sales person didn’t do a great job of explaining what is possible with your system and setup. There are limits and oversizing equipment (even if it fits in the closet) doesn’t = giving you more cooling power. Ducting affects how the house cools a lot more. Honestly, your particular setup would’ve benefited greatly by a hybrid system of air conditioner properly sized /with/ a mini split system for your grow area and server farm specifically. That probably would’ve helped.
