Marine Air Conditioning
Got a Compressor that is a bit hard starting...Maybe marginal Shore Power or Generator causing Tripped Breakers, Lights Dimming, or Battery Backups beeping every time the A/C starts...This could be your answer... I have installed several and found the claims to be true... The instructions are pretty straight forward, but I can also provide an installation video... Steve~ … [Read more...]
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... Lack of seawater flow causes high system … [Read more...]
I notice from the Google searches...That A/C System Icing is a search done often.. Though there can be many reasons for system icing...There are a few that the DIY boater can rule out before calling the service guy ( I can discuss other reasons in the forum but here are a few of the basic answers) Direct Expansion A/C (as opposed to Chilled Water) systems rely heavily on Air Flow across the evaporator coil in order to pick up the designed amount of heat the system was engineered to … [Read more...]
Due to new 2010 EPA regulations regarding the phase out of our long used R-22 A/C refrigerant systems... Here's what I can share at this point from the Cruisair/Marine Air perspective & what I have been told. … [Read more...]
It's the time of year that we all need heat…Even here in Florida this year…Global Warming My…? Anyway… Below is a post I answered in the Hatteras Owners Forum, and it seems to be a subject that many of you all are searching for answers to this time of year…It also applies to cooling in the summer, but is mostly about system Icing & the causes…I'm also going to link this article to a Forum post here on this site so that anyone that may have questions or need further … [Read more...]
Hello All...A New Year again...Hopefully yours was good.... I started this site last year to "put my feelers out" about what owners and captains may want to learn and share about marine a/c. The support has been more than I ever expected... So... My New Year resolution to you is expand the site we created...Because of your feedback I am going to begin adding to my store to allow you to order most of the common Marine A/C system items that I found you've needed, but … [Read more...]
Below is another copy of a post I made in the Meridian Owners Forum...If you want the full jest...http://www.meridianyachtowners.com/forum/forums/thread-view.asp?tid=1957&posts=15#M18424 Hi Mark...Don't know if you are still watching this thread, or if you have seen my thread over in the "Introduce Yourself" forum but here's my take... It seems that when the system was flushed, that it was flushed just well enough to break loose some stuff...Now it is floating around in the hoses and … [Read more...]
Copy of recent e-mail to Marine AC.com... Hi Steve, love your web site - lots of great info. ! Our company does a lot of yacht maintenance / mechanical preventive maintenance type stuff here in Wilmington, N.C. - my question is, do you have an opinion concerning back flushing the sea water lines on marine air conditioning systems ? That is, do you think there is any benefit to occasionally (2 or 3 times per season), removing the water discharge hose and connecting a dockside water hose to the … [Read more...]
Recently I was on a boating message board and came across a discussion about pumps and some troubles folks had experienced. The original poster had a March magnetic drive pump that would not pump water, and after the usual back flush & priming sugguestions he could still not get it to pump water…Just before I read the thread he had found that either something had gotten past the strainer (or he didn't have one) and had lodged between the impeller magnet and the pump housing … [Read more...]
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...]
Thanks to my webmaster brother Capt Scott...We now have a forum section...Whoo Hoo !!! Everyone can access it, but registration is required to post...I don't share that info...You can find the link at the top of any of Marine -AC.com's pages...Just click on "Forum"...Or you can click on this http://marine-ac.com/forum/ We are slowly growing, and I seem to notice from the searches what folks do to find Marine-A/C.com. I also see that many are either not finding the forum and/or … [Read more...]
