Here is a video describing how to reverse winterize your boat air conditioner.

The self-contained units we mostly install today have water cooling and copper fins for durability and efficiency. They often use super quiet magnetic drive pumps. They come with digital touch controls that can help you control humidity, air flow, cooling and amount of heat needed. 

You can learn more about how these units work on our FAQ page here. You can also learn more about diagnosing air flow and water flow issues on our YouTube channel here.

Boat AC.net stands behind our work. We want to make sure all of our customers are satisfied and will provide warranty service from the manufacturers for our customers.

We don't believe online marine ac unit calculators or ac size calculators are the best solution to air conditioner sizing. However, we can help you size your boat ac units on a quick phone call.

Here are some common questions we hear from customers interested in installing AC in their boats.

How Long do Marine AC Units Last?

While some units can last as long as 15 years, most units installed 10 years ago or more are no longer functioning properly. Because of the extreme conditions of marine applications, it usually isn't viable to fix units past about 5 years if one or major components fail. We are often replacing Dometic Cruisair marine air conditioners that are 10+ years old.

New units, like the Marinaire 16000 BTU marine air conditioner, are much more efficient than older cooling systems and air conditioning units. They provide colder air in the summer and warmer air in the winter than older units while cleaning returning air better.

We also find that newer salt pumps, like March circulation pumps are much quieter and more efficient than older units, especially on larger units like 16,000 british thermal unit marine a/c units.

Can I Run My Boat AC on Battery Power?

Most existing battery systems on boats don't have the capacity to run air conditioning for more than a few minutes. However, there are some available Lithium Ion battery systems that can provide the power to run AC unit(s) all night on battery power.

They also shut off gracefully - so that they don't damage your marine AC system or other key systems on your boat. BoatAC.net has designed and installed some of these battery-powered DC marine AC units. They tend to be much costlier than shore or generator powered units, but are definitely viable for most boats.

We have installed 12 volt DC 12000 BTU air conditioners that can run through the night entirely on battery power. You can visit our page dedicated to battery-operated marine ac units for more information.

How Does the Air Conditioner Work on a Boat?

Modern Marine AC units work as water-cooled heat pump air conditioning systems. On our FAQ page here, we provide a detailed description of how marine air conditioning works and how all the components fit together. You can also check out our How Boat AC Works Page.

Can I install Air Conditioning on my boat Myself?

It depends on your skill level and how many trips you want to make to the marine parts store! Marine air conditioners involve raw water, pressurized refrigerant, AC and DC power, ductwork, finish carpentry and require thru hulls for raw sea water.

Most of our installations require an assortment of dozens of plumbing, electrical and ductwork fittings and specialized tools. Check out our DIY Boat AC Installation Guide.

Replacing your boat's AC often requires a dozen or more specialized fittings because new units and 10+ year old units use different connectors.

If you are considering installing a marine AC system yourself, give us a call and we can help set your expectations.
