The MarinAire product has an attractive price

Manufacturer of quality marine air conditioning units and self contained marine air conditioners - Home
Has anyone had experience with this product line? Is is a quality product? Has it been reliable and functional? How about noise
levels of the product - at start up, shut down and continuous running? Is is louder/quieter/same as other products?
I know little to nothing about MarinAire. I do have experience with a similarly named company, Marine
Air Systems, but they are not the same company. Marine
Air has been around a lot longer than MarinAire. Marine Air was bought by Dometic a few years ago. Marine Air products have been widely used by builders for many years and quite a lot of them are still running. Including mine which is over 20 years old and still going strong (and quiet).
If you want totally quiet operation then I recommend a split system like the one we use. It has a small compressor
unit that sits in the very aft under the aft cockpit
seat (but inside where it is dry). The evaporator is in the main cabin
. They are connected by two refrigerant lines. At night I can barely hear the compressor
run. Such a system is significantly more expensive but the quiet is worth it to me.
If the only thing wrong with your system is the noise then look at it closely. The compressor motor
is usually mounted with rubber shock mounts. These eventually wear out and then the motor
vibration becomes an annoying rattle sound. Replacing the shock mounts might make it as quiet as when it was new. However, if the internals of the compressor are knocking about then new shock mounts won't help.
