We are now installing Airlock Marine Air Purifiers for the same reason. During the busy boating season, Eric and his wife often sleep on their sailboat. Despite cleaning absolutely everything, there was still a "boat smell" that just wouldn't go away. The boat smell would get into their clothes. They'd heard from someone about Airlock, but were skeptical. They decided to try it anyway. Airlock worked. Their sailboat no longer has that boat smell. They sleep easier. People no longer ask them if they live on a boat because of the smell on their clothes. They now sleep in air conditioned comfort without the boat odor. Why use BoatAC. net to install Airlock Marine Air Purifiers? Clean air on your boat starts with a well-performing marine air conditioner. While Airlock devices are pretty simple, they require proper installation. They should turn on and off with your marine ac unit. You want a factory-quality installation with marine-grade wiring, attention to detail and proper placement. This is what we do every day for customers for their marine ac needs. You can trust BoatAC. net to install Airlock correctly.

They also can provide even very large vessels with centralized, space-efficient marine HVAC. They work with local air handlers in each are to be cooled. As a Frigomar Distributor and Service Provider, BoatAC. net offers repairs, new installations and upgrades for all of Frigomar's Marine Air Conditioning Systems. How do Marine Chiller AC Units Work? In ocean aircon systems, chillers circulate cold water from a central chiller location to chilled water air handlers in different parts of the vessel. By using water to transfer heat, chiller systems are able to efficiently cool an entire vessel with one or a small number of centralized chiller units and a chilled water air handler in each zone ensuring that ac flow is effective and efficient. The water is chilled by the combination of an evaporative refrigeration cycle and by using outside seawater to "dump heat" into the sea. In this way, they work much like geothermal air conditioners. This type of air marine system uses much less energy than an air to air style heat pump air conditioner. Marine AC Chillers Water is used instead of refrigerant because it allows the heat transfer to happen at longer distances and is much easier to work with. The water then passes through air handlers that pass air over the coils - cooling it and removing some of the moisture. Some units also offer reverse-cycle... --- Marine Air Conditioning in North Carolina & South Carolina Marine Air Conditioner Services in South Carolina and North Carolina BoatAC. net helps boat owners in North Carolina and South Carolina keep cool in the summer and warm in the winter.

Mabru units are especially compact for tight spaces A typical boat ac installation requires dozens (or hundreds) of specialized marine-grade parts in addition to the equipment that comes with new Marinaire, Mabru, Dometic or other new marine ac units.

Sailboats have some unique characteristics to consider as you consider different systems. Here are some questions and considerations to help you decide on the best options for your sailing vessel. Stay comfortable with self contained marine ac. 12v air conditioner or 115/230 volt marine a c? With the growing availability and improved price/performance of lithium marine batteries, it's become viable to run your boat's ac and/or heating directly from batteries. Battery-powered marine a c units are now about 20% of our installations. We generally recommend Mabru for their ac 12v units. We've installed 12v systems from 6000btu air conditioners to 16000 btu boat air conditioners. In fact, some of our customers have multiple 12v marine ac systems on their sailboats. They're able to cool multiple cabins with independent thermostats with their 12 volt ac. Some customers have found an excellent additional use case for their 12 volt air conditioner - to blow cool air into the cockpit on hot days and to keep their head and cabins comfortable while sailing. When running on batteries, these units are quiet enough to use under sail without spoiling the experience. Quiet comfort at anchor with 12v marine ac.

One such option is the boat hatch air conditioner which promises to provide a cost-effective way to cool the cabin. However, while this may seem like an ideal choice on paper, there are drawbacks that need to be taken into consideration - namely its noise level and lack of power when compared with other cooling options available on the market today. Mabru 12v Marine AC Unit Hatch air conditioning units function like window air conditioners in homes. They use the compression and evaporation cycle of refrigerant to cool the air. They use outside air to cool the compressed refrigerant. As a result, they generate a lot of heat on deck near the units. Portable Air Conditioners Portable air conditioners have been known to provide a much-needed cooling solution for many people in their homes, boats, and even RVs. They can be easily set up in any area and are generally less expensive than permanent centralized air conditioning units. However, with the added convenience comes the drawback of lower efficiency and not being suitable for long-term use in marine environments. Most portable air conditioning units are air cooled and have to push the heat from the compression cycle into the nearby outside air. Because they tend to have less outside surface area than similar hatch units, they're often less energy efficient. Marine Air... --- Marine Air Conditioning Maintenance Marine AC Maintenance How to Maintain Your Boat AC Whether you're enjoying a weekend getaway or embarking on a long voyage, there's nothing quite like the comfort of cool air conditioning on your boat. But to keep that refreshing breeze flowing all season long, proper maintenance is key. On this page, we'll walk you through some simple steps for maintaining your marine air conditioning system and ensure smooth sailing ahead! Air can't move through dirty coils! As Eric often says when considering marine ac maintenance, you need 3 things to make your boat's air conditioner work: Free flowing air over the condenser(s) to prevent the coils from freezing Enough seawater pumping through the system to keep up with the heat generation Consistent power with enough amperage for start-up and running (note: many of the newest ac units have soft starts and/or variable speed compressors to reduce the starting power required, but older units don't typically have this) Before we get started, make sure you properly winterize and de-winterize your boat ac system by removing the seawater from the system. Clean or replace the air filters of your boat's air conditioner. Most boat ac units have more than one air filter. Make sure they're clean! Most ac units have 2 or more air filters. You'll want to make sure you remove the return air grill to get access to the outermost filter. Also, most ac units have a second air filter closer to the a/c unit itself.... --- Marine Air Conditioning in New Jersey Air Conditioner Marine Repairs and Installations in NJ New Jersey's Premiere Marine Air Conditioner Specialists If you're a boat owner in New Jersey or anywhere from the big apple to Cape May, then you know how critical it is to have top-notch air conditioning aboard.

Heat pumps are extremely efficient solutions for heating homes and buildings. They are more efficient than hot water, steam or furnace systems. But, do heat pumps work well for marine applications? It turns out that air conditioners with heat pumps are even MORE efficient on boats than they are in homes and buildings in cold weather. They're cleaner than propane boat heaters or diesel boat heaters, more environmentally friendly and not only do they use less power than electric boat heaters, they also provide air conditioning when the seasons change. Unlike boat diesel heaters, heat pumps have no flames or smoke. And, their noise level is low and consistent - no crackles or banging as they heat up! Also, most come with remote controls. They are very similar in operation to geothermal heat pumps (aka ground source heat pumps). How do Heat Pumps work? Heat pumps are basically air conditioners that run in reverse. They use a refrigerant (like freon) to transfer heat from one area to another through an ongoing cycle of compression, movement and evaporation. Our how marine ac works page explains this in more detail. Heat pumps can run from 115v or 230v shore power of can be used as a 12v heater for boats when connected to an appropriately sized battery bank. See our page on battery-powered boat AC here. Heat pumps are able to capture heat from... --- How to Clean Boat AC Seawater System Seawater Flow Issues in Boat Air Conditioning If your marine air conditioner isn't working properly, one of the most common problems is restricted flow of seawater through your ac unit. If your seawater pump seems to be struggling or if you're getting HPF or High Pressure warnings, you likely have some barnacles or other debris in your seawater cooling system. Before doing any sophisticated or more involved work on your marine circulation pump or your boat's air conditioning system, remove and clean all the filters and do the same with your strainer to maximize heat transfer (MAKE SURE YOU CLOSE YOUR SEA COCK FIRST). Probably not a lot of water flowing through this strainer... Check out our Marine Air Conditioner Troubleshooting page for these and other recommendations on determining why your boat ac isn't working properly. Whenever working on your sea water pump, make sure that you've closed all the valves below sea level. Once you get through those, if your thru-hull discharge still seems to be discharging less water than previously or isn't flowing smoothly, your marine heat pump or marine air condition system won't be able to pull heat or dump hot water into seawater quickly enough for optimal performance. We see more water flow issues on boats that are moved less often, boats that are stored in well-protected marinas or harbors, boats that often travel in shallower, muddier water and boats with older marine ac systems. Most water flow issues... --- How to Install Marine Air Conditioning NEW: BoatAC. net now offers remote technical support for customers who want to install their own AC units.

In the past few years, technology has improved a lot. There are now very efficient, small and quiet marine air units available with digital controllers, reversing cycles (heat and AC! ) and integrated air handlers. If you want to install an air conditioning unit on your boat, you'll have some great options. BoatAC. net usually recommends Marinaire and Mabru Power Systems ac units for boats. We also support Webasto, CTM-Marine and Dometic Marine. They're self-contained air conditioners and many feature reverse cycle heat pumps that can help you stay cool on warm days and warm on cold days in your boat's cabin. The installation can be complicated, so if you aren't comfortable with a 3+ day project, you should consider hiring a boat ac installer to help you install your boat's ac system. If you have done a lot of boat systems work before, air condition marine a very serious project that involves many different systems. Sailboat ac can be even more complicated... --- Common Questions About Boat AC Units How much does a boat air conditioning unit cost? There are many variables that make it difficult to give precise estimates for marine air conditioning unit installations for boat owners. To install marine air conditioning on a boat that doesn't have it today, you'll need to drill for both raw water intake and discharge. You'll also need to install a condensation pump, new shore power, new circuit breakers, run all the ductwork, install air returns, air vents and a thermostat. You can see more details here on how to do DIY marine AC installation. A good rule of thumb is that a professional high quality marine airconditioner installation is usually between 5 and 10 times the cost of the unit itself. There really aren't airconditioning retrofit units or retrofit kits available for most units as technology and vendors have changed quite a bit. Replacing an existing AC unit can vary from 2-5 times the cost of a boat ac unit depending on how many components need to be replaced or reinstalled. How long does it take to install marine ac? For most customers, BoatAC. net can install marine air conditioning and have your boat ready to go within 1-2 weeks. We also offer emergency service if you're on a tight timeline. If you have an existing system, we can usually replace it while the boat is in the water. If you don't have AC and want it installed on your boat, you'll need to... --- Troubleshooting Marine Air Conditioning Why isn't my marine air conditioner working? 9 Tips To Get Your Marine Air Conditioner Working 1. Clean your boat A/C system's air filters - all of them on your marine air conditioning system Dirty boat ac filters break air conditioners It's important to learn how to clean boat air conditioner filters and coils. Your boat's AC system probably has at least 2 air filters. Many people only check and clean one of them. The second filter is usually on the unit itself. If you have a split system with separate air handlers, you likely have at least one filter on those. You should remove and clean or replace all the air filters on your boat at least once a season. If you are living on your boat, we suggest checking and cleaning them 2 or 3 times a season. Look for any blockages or debris on the the air vents or returns - which could be in the engine room, the cabin or near the unit itself Dirty air filters can lead to boat ac freezing up If you experience boat ac no air, check your filters first! Clean you boat ac air filters well! 2. Check your boat's ac pump (raw water / sea water pump) for water flow When you turn on your boat's A/C water pump, water should immediately begin flowing out the discharge port from the chilled water system. If you don't see a steady, fast flow of air conditioning water,... --- Marine AC and Refrigeration Boat AC and refrigeration repairs and installations.

First, let's discuss the components of your marine air conditioning system that make noise - in order of what are usually the noisiest: The air conditioning pump, otherwise known as the compressor, that compresses the refrigerant as part of the ac cycle The circulation pump (aka salt pump or raw water pump) that moves seawater through the water line to remove the heat (or cold, when running reverse cycle as a heat pump) The air handlers that suck cabin air through your returns, push it over the coils and then through your vents The return air grills and vents can cause noise, especially if they're too small for the amount of air flowing through your system Control Temperature and Humidity on Your Boat To reduce the noise in these components, there are some common themes to ensure that your boat's HVAC system operates quietly. Purchase (a) unit(s) that are well made and efficient. We prefer Marinaire units that include extra noise insulation around the key components - the compressor and fans. If your boat has an engine room, try to install the noisiest components there as most are already well sound-insulated Make sure your return air grills, ductwork and vents are sized correctly. If there are any obstructions to free flowing air, they can cause excess noise. Additionally, keep in mind that closing or opening vents can impact the noise level at other... --- How Does Marine Air Conditioning Work? How Does Marine Air Conditioning Work? We are often asked how does ac work on a boat and how those differ from the AC systems in houses. We are going to focus specifically on different types of marine water cooled air conditioning systems. Unlike most conventional air conditioning systems, marine ac units have access to an unlimited supply of cool water. This is why ac installation is a bit more complicated on boats than a home ac system and also why marine AC units are usually more energy efficient than air-cooled heat pumps and ac units. If you're wondering how does boat ac work, we detail the mechanics of marine air ac below. Let's start with some basics. Water holds heat very well (it has a high specific heat capacitance). In contrast, air does not hold heat particularly well. This is why water cooling is so helpful in marine HVAC - the chilled water helps dissipate the heat from the compression cycle. On some deep-keeled sailboats, instead of running seawater through the ac unit, the unit runs liquid coolant on a loop through the keel where heat (or cool) is then transferred to the water around it. This is how sailboat ac differs in some cases. As a side note, higher humidity levels in the air increase how much heat the air can hold and how quickly that heat is transferred to what it touches - which is why humidity makes hot air feel... --- Marine Air Conditioner Services Boat AC Installations and Repairs. https://boatac. net/wp-content/uploads/2023/05/Call-Boat-AC. mp4 BoatAC. net services marine air conditioning systems on the east coast of the US.
