Re: 86 carver mariner/add air conditioner easy or hard
Depends on what you consider 'easy'.
What size Mariner? They were made from 28 to at least 38 feet.
Basic installation:
-set A/C unit in place
-install ducting (supply and return)
-install circulating pump, intake and discharge thru-hulls
-run all water lnes
-run condensate line
-connect electrical
-install thermostat
As far as cost, a basic 12000 BTU unit with reverse cycle heat should run about $2,000- not including the equipment needed to install. Figure another $400-500 for that and you're at $2,500 with no labor.
Depending on the boat size and geographic location, a second A/C unit may be required for proper cooling.
Hope that helps.
