A/C - is Coleman Mach 15 a drop-in replacement for Mach 3
I need to replace the OEM Mach 3 (13,500 BTU). We only have 1 A/C, so I would like to put in the more powerful Mach 15 (15,000 BTU). It is only about a hundred bucks more than a Mach 3, I found one for less than $600.
I looked at the two installation instructions, they use the same illustrations. No pictures of the wiring, is the wiring identical?
Anything I should know before I DIY this upgrade?
