Time for a new A/C ?
SO we are getting ready for a trip next week and DW says A/C is blowing hot air. Well it's not hot just not very cold. So I pull the cover and the compressor is too hot to touch. Coils are all cle...

Swapping (I had pros do it) is fairly easy from a description point of view.
There are 3 swaps.
1: Same/same
2: Adapt-a-kit
3: Different make or model
I will cover the first two since they are basically identical, Mine was a type 2 (Adapt-a-kit).
They replaced a Carrier Air V with an Advent top unit, In this type of conversion you do NOT replace anything else save for one electrical connector (This may not always be the case either) I do not know why they did not design the adapt-a-kit so you did not have to replace that connector.
Remove inner cover (4 screw) and unplug cables to roof unit from control box
Remove 4 larger bolts that hold the roof unit on
REmove roof unit, if necessary remove and replace gasket
Position new roof unit, replace 4 bolts tightening as per instructions
Adapt-a-kit special step: Replace the one socket and harness, NOTE: the instructions said to do it, not now to replace a MOlex connector. thankfully I know that one (It's obvious if you look at it properly)
RE-connect harness to top unnit (in this case with an adapter cable)
TEST
Replace inner cover
That is all there was to it.
NOTE: This is for a ducted system,, If you have a non-ducted system go ahead and replace the inner parts as well (inner = indoors = ceiling)
NOTE that I did not mess with the duct work or the duct adapter (the part actually IN the ceiling) save for replacing that one elctrical connector.
Sounds easy doesen't it.
Now for the kicker... Check the shipping weight of that roof unit, Now, as it happens it is possible I MIGHT be able to horse that sucker up a ladder.. I'm big, I'm strong, I have climbed a ladder with that kind of weight in the past.. The far distant past.
That is why I hired it done.
The man who lifted it up to the roof needed but a couple fingers.... On the hydraulic valve of the tractor mounted front end loader.. To lift the new one up and the old one down.. TWO strong men on the roof positioned it.
