Upgrading Air Conditioner
Was thinking of upgrading to a 15,000 btu air conditioner. Have a 13.5 now and with a dark brown MH it cant keep up. I am going to do this myself and wondered if there are any special things I need to...

My motor home has 2 A/Cs Carrier Air V out of the factory
Well Carrier did a bang up job of building them and as a result one failed in a away that was beyond what the repair guy wished to fix so I "Upgraded" the top part only to an Advent Air with an adapt-a-kit,, I will describe in full the upgrade.. I had to do part of it myself, (Will cover that too).
The Air V was 13,500 BTU and draws 13.5 amps running
The Advent is 15,000 and draws 13.5 amps running. It is bigger, a bit noiser and a bit heavier but Well, you only notice the weight when installing and the noise for about 10 seconds. (Always run your A/C on HIGH, never auto, your brain will very quickly filter the noise of the blower if it runs constantly, not so much if you run it on AUTO).
Now I had a dealer do the upgrade.. (Most of it)
The ADAPTOR kit consists of one "Y" cable, one MOLEX socket with pigtail (2 leads) and 4 bolts.. Plus the instruction booklet (Paper)
The upgrade
Remove inner cover and unplug the Upper unit from control box (2 cables)
Remove 4 bolts and lift off roof unit, set aside
Open control box, remove the MOLEX connnector indicated in the instructions (This is the part I had to do) and replace with the included Molex connector (Again I had to do this, Dealer Tech had never replaced one before, I'm trained in electronics and have worked with them, comes from bulinding Heathkits and the like in the old days,, By the way if anyone has a Knight Kit Star Roamer for sale, please Let me know.. My first major build and I'd like to have one for nostalga sake).
Plug adapter "Y" cable onto control box (only connects one way)
Using front end loader lift new unit to roof, replace with old unit in lifter bucket and lower to ground.
Set new unit on gasket (NOTE: inspect and replace gasket if needed) and line up the bolt holes Insert bolts, Plug top unit's single cable into adapter cable's remainign connection, test, replace inner cover and filters, job done.
Can I haul one of those up a ladder... Well, I've hauled that much weight up a ladder in the past, several times, but that was 40 years ago and today...
