Swapping two AC's. Much of a job? Bounder 34ft

I have a 97 Bounder
About a month ago, on a nice cloudy day
I turns off power to the a/C units and unplugged the power plug on the Intellitec unit
T then I removed the wall Tstat control
Open it up and unplugged and cleaned all board connectors
I then sprayed contract cleaner into the sliders and switches and worked everything really well
After putting it back together, it does work better

Also some canned air to blow the dust loud of the two wall mounted temp sensors
