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?
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.
