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

[Scott Hall]

Ben,

This is exactly my interest in a mini-split--I can keep the master bedroom
cool and the rest of the house at 75 degrees. 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.

The only issue I'll have with a mini-split, besides that the outdoor unit
will be hanging twenty feet in the air is that the indoor unit isn't
meeting the aesthetic requirements imposed.

I mean, she's right--it is kind of ugly, but being able to keep the master
bedroom at 65 degrees for cheap has a beauty all its own.
