My motor home came with Carrier Air V's. as you know Carrier is no longer making RV Air Conditioenrs (Wonder why> Design flaw killed 'em young).
I replaced one with an AdVent Air (DO NOT recommend)
and the other with a Coleman.
Now imagine my surprise when It came time to clean the condenser.
Colemans suck (not in a bad way) meaning they draw air IN over the condenser and exhaust it via the sides.. Most every other make blows (Pushes air through the condenser)
What does this mean
Coleman.. Remove outer cover (4 screws) and peal or brush the condenser clean. Replace cover and screws and done.
OThers Remove cover (usualy about 10 screws give or take) Remove INNER COVER (varies from 4 more screws to cut tape and bend tabs) and FAN then you can clean the condenser....
Now you know why I like Coleman.
