This is the second unit we have had in two boats. They last a long time. The new owner of out last boat just had to service
so it lasted for 19 years. He replaced the scheader valve and recharged and it's fine again. Reverse cycle is worth it too as I think the heater when the raw water
is above 45 degrees F works better than the A/C. It's nice to just set thermostat and make it automatic too.
The one item about it that you do need to be more selective about is the circulating pump. I don't think they come with one and it could be easy to wimp out on buying
one. I like the March pump as the pump head
is a different part and you can replace just the pump head
. They cost a bit more though it's the one thing you have trouble with if you get a cheap
pumps are terrible and unserviceable.
Of course you need a through hull
and strainer as well as a plan for draining the condensate that developers in the pan under the cooling
coils. Air locks in the raw water cooling
lines can easily form so make sure the line is easy to get at and make it as short as possible. Our current
boat has a bad habit where an air bubble always is formed at the top of the sea strainer after prolonged non use. It forces me to open the top and close it again before I start the pump. Not bad as it also forces me to check the strainer too. The Cruisair does have an over temp cut off if you lose cooling water
so it can't burn itself out.
