[Shop-talk] It's hot and I want AC

[Battmain battmain]

If you search hard enough, there are a few that look slightly better than the oval retangular look of most of them. Those look like a flat box that slides open when operating but I felt just more moving parts to break. You also pay a noticeably higher price too.

I have a Mitsubishi unit. It has the oscillating vents and they work fine. I did not get to place the inside unit in the middle of the wall where I wanted due to outside real estate and a fence, but it doesn't seem to matter. It can cool the room from f'ing hot to tolerable in about 15-30 minutes. The remote has a timer where I can set it to start at a certain time if I want, but I have the central AC on a smart/remote thermostat with a schedule instead. Alexa also has a routine to ensure central AC set to 'Away' in case I override the schedule and forget in the morning.

As far as warranties, I'm about to have to replace a four year-old central a/c system on my dime still very much under warranty and installed by a professional...so I'm failing to see the value in warranties right now.

>> I did a mini split unit for my master bedroom. The hardest part was getting through the 12" poured concrete at the base of the roof to run the lines outside. A rented hammer chisel took about 2hrs and a lot of cussing. I love the unit though and so does my wallet. The central AC does not have to be set as cold and the mini split runs when I am in the room. The online electrical stats show the unit pulling less power than my toaster oven most of the time.

That way if one can't cool the space, you can use the others to help. These things are so efficient I was considering ripping out the central AC I just put in and adding one to each space in the house. Install was relatively easy other than the concrete part and was a much easier than the central AC install.

>>> Anyone installed a mini-split AC system in their shop?  It looks like its effective and can save a bunch of money if you do it yourself.  My problem is sizing it.  I've got about 1000 sq ft (35 x 28) with 17' ceilings.  Two insulated overhead doors (12x14 and 10x10).  The shop is reasonably well insulated (mostly) and I'm in southern Indiana (often low-mid 90's and humid).  I'd probably put it midway up the wall and have it blow out into the bays.
