Marine Air Conditioning

Marine AC repairs and installations. We repair and install boat ac on sailboats, powerboats, and working vessels. We are based in Maryland, but offer services around the world. We can provide in person or remote support anywhere in the world for your marine air conditioning projects.

NEW: BoatAC.net will travel to you for larger, more complex installations, repairs or replacements of marine air conditioning systems, chillers and boat ac units. BoatAC can design your system, ship you all the parts you'll need (including all the specialty hoses, clamps, wires, etc) and even travel to your vessel to do the work for you, if needed. We can also provide remote support to owners and boat mechanics who want to install MarineAC systems themselves.

BoatAC now supports chilled water systems. We have factory-trained technicians for Frigomar Chiller AC systems. We can repair chiller systems, install new Frigomar system single phase and 3-phase Chilled Water cooling systems and replace existing chillers. We are also now an authorized Frigomar distributor. We install Frigomar 230V self-contained heat pump ac units. We also install their 24v boat ac and 48v marine air conditioning systems. 

Our extensive knowledge of marine air systems helps us quickly resolve customer issues for cruisair marine air conditioning and other systems. 

BoatAC.net Installs Hull Shield Anti-Fouling Systems

We are factory-trained installers and an authorized distributor for Hull Shield Solutions. With Hull Shield HD1 or Hull Shield HD4, boaters will enjoy dramatically less marine life growth on hulls AND drivetrains! Automatic protection against all common types of marine life including barnacles ensures better performance, more safety and less fuel consumption. Learn more about BoatAC's Anti-Fouling installation services. 

HPF Errors

By far our most common request is to help customers with High Pressure Fault (HPF or HP on most displays). If you experience one of these, first check and address your water flow, air flow (air filters and evaporator coils). If you find that your refrigerant is low (ie freon), it's usually better to replace the unit than try to find and fix leaks. With self-contained units, leaks are usually symptoms of broader corrosion (kind of like plugging one hole in a dam).

We always have boat ac units in stock and have great relationships with manufacturers like Marinaire and Mabru if we need to order new marine ac units. We offer marine ac winterization services and launch services for your boat's ac units. We support 12v battery-powered (or 24v DC) marine air systems as well as other air conditioners for boats.
