4 Tips For Marine HVAC Maintenance

For the comfort of your river, lake, or ocean voyages, your marine air conditioner needs to be kept in its best shape.

The marine HVAC system is an important part of any watercraft, as it heats, ventilates, and cools the inside of the boat.

In this blog, we’ll review some tips you should follow in order to make sure that your vessel or yacht’s heating and cooling systems are working properly at all times.

#1. Clean the air filter of your marine air conditioner

Cleaning your boat’s air filters is the easiest maintenance task you can do. Remove the panel cover of the filter and inspect it for dust and fluff. If you notice considerable accumulation, then remove the filter and wash it with running water. Reinstall it once it’s completely dry.

How often you need to clean this filter depends on how frequently you use your vessel and the HVAC system it has. In normal conditions, cleaning air filters once a month is appropriate, with more cleaning taking place in the summer.

If you need advice about how to best clean your boat’s air filters—or need advice about when to replace the filter—contact the professional team here at Bob’s Heating & Air Conditioning.

#2. Clean your sea strainer for better cooling

Like air filters, sea strainers play an important role in the cooling process because they filter out all foreign pollutants and debris from the pumped water used to cool off the heat produced by the engine and marine HVAC system.

Cleaning sea strainers can be done without much hassle. Shut the seacock off, open its casing, and pull the basket cylinder out. Flush this mesh cylinder with a hose to clear any debris. You can also use a scrubbing brush to clean every last single remnant of debris. This is recommended.

Here’s a helpful video detailing the best way to clean you sea strainer.

Once you are done cleaning the sea strainer, place the cylinder in its housing. Close the strainer, open the seacock, and run the system to check its efficiency and to make sure everything looks good.

#3. Check the evaporator coils

The evaporator coils are an important part of any air conditioner, and your marine air conditioner is no exception. There are several indicators of an improperly functioning evaporator coil that you need to keep your eye on:

  • Inefficient cooling ability
  • Increased energy consumption
  • Frost buildup on the coil

If you see a buildup of dust on the coil fins, remove it through an air blower. If the problem(s) continue after that, you’ll probably need to call our team for marine HVAC service.

#4. Schedule marine air conditioner maintenance

Lastly, check the condenser unit of your marine HVAC system. This is the system that takes the biggest beating from all the debris and rubble in seawater. Seawater is corrosive in nature, so you need to protect the condenser from its effects.

Condenser units must be flushed chemically once a year for better performance. If you’ve been putting off this service, give us a call. We provide marine air conditioner services in Berwick, Morgan City, and other parts of southern Louisiana.
