Help with Mini Split sizing

[Mike D]

I have a 30x40x14 shop that is spray foamed. My installer did a 2400BTU Mitsubish and it works great. It will cool that whole shop down quickly. The Mitsubish has a “sensor eye” that directs the cool to the correct part of the shop that needs the cool. You can also set it manually to blow where you want it (working under the truck I point the unit in that area). Heater is nice in the winter and it has a dehumidifier setting also.

I’m assuming you meant 24,000 BTU and not 2400.

I have a 7k BTU unit on my reloading room that spray foamed. It has heat and cool capabilities. It’s and LG and keeps it 68° year round in there.

Bowhntrmatt- why is installation so important on these. Helped with two that seem to be doing fine. I agree with getting the right size unit for space but installation is simple on these from my experience and I have zero skills

Man, I've seen it all. My favorites include the lineset rolled up next to the unit because the installer didn't have the tools to cut and flare, or just dangling down the wall without being covered, Units not leveled properly, running 3/8 clear tubing for a drain line, improper wire sizes for both high and low volt, sizing issues......
lots of very sloppy installs out there, basically. Sure, there are plenty of Chinese units out there that work just fine, especially when new. The issue is when they break and being able to diagnose issues and find parts in a timely manner.

So that’s 2 tons for 1200sqft and high ceilings….that helps!
