Marine Air Conditioning System Maintenance

DSCF1533

Greetings All, Let's start with the basics... Seawater flow thru your A/C system is primary... Without water flow....You have NO cooling ! Service people on the docks (at least the better ones) can walk down the dock during the summer and tell which boats they are likely to be getting a call from next just by the flow of water (or lack of) going overboard on each boat....Lack of seawater flow can cause other problems besides loss of cooling...

A/C System Ices Up

Ac System Icing

Marine A/C Cabin Controls

MarinAire Retrofit-Control1

Since they are not like home A/C controls...Sometimes marine A/C controls are misunderstood...Hope this can clear up some misconceptions... They do provide the same function as in home systems as they are designed to keep the temperature in the cabin/room at a selected temp within a few degrees... But different than Home...They can (and most do nowadays) offer more/different features than we use at home depending on the type of marine control that is installed...We can cover some of those … [Read more...]

CruisairPumpRelay

We have touched on seawater cooling and lack of...Now what about if you have a intermittent problem, or the pump won't start at all ? In boats with multiple systems running on one seawater pump there is most likely a Pump Relay to receive a signal from each system to tell the pump it needs to run...That is unless it has been bypassed and the pump runs 24/7 from the breaker ( I see this done fairly often) Lets start with the breaker in the main panel...Most are labeled A/C pump or … [Read more...]
