New System Installation

Installing a new marine A/C system is more than just putting a box in the bilge. It's about engineering a solution for your vessel. We consider everything from the power draw on your generator to the optimal placement of ductwork for quiet, efficient cooling. Whether you're commissioning a new build or finally adding A/C to your pride and joy, we ensure a clean, professional installation that integrates seamlessly with your boat's existing systems.

We are certified installers for top brands like Dometic, Webasto, and MarinAire, ensuring your warranty is protected and the job is done right the first time. Don't get caught on the hard with a poorly planned system; let our experience make the difference.

System Upgrades & Retrofits

Is your old A/C unit loud, inefficient, or just plain tired? The dock talk is true: modern systems are a world apart. We specialize in retrofitting new, high-efficiency air conditioners into older vessels. An upgrade can drastically reduce noise, lower your shore power or generator load, and provide superior cooling and dehumidification. We handle the removal of the old unit and ensure the new one is plumbed, wired, and installed for optimal performance.

Need a repair instead? We do that too.

Ductwork & Air Handler Placement

Proper airflow is the secret to a great A/C system. Any old bilge rat can run ducting, but it takes an expert to design a system that delivers cool air quietly and evenly throughout your vessel. We strategically place air handlers to eliminate hot spots and minimize noise in sleeping quarters. Our team carefully plans ducting routes to maintain velocity and reduce static pressure, ensuring your system breathes easy and works efficiently.

Frequently Asked Questions

How long does a typical marine A/C installation take?
A standard installation can often be completed in a full turnaround day, but it depends on the vessel and system complexity. Custom ductwork or fitting it into a tight bilge space can add time. We work efficiently to get you back on the water as soon as possible.
What size (BTU) A/C unit do I need for my boat?
BTU sizing is critical for efficient cooling. It depends on your vessel's volume, window area, insulation, and even where you boat. An undersized unit will struggle, while an oversized one will cycle too quickly. We'll perform a detailed load calculation to ensure you get the perfect fit, so you're not just burning diesel.
Can you replace my old, outdated marine A/C system?
Absolutely. We specialize in retrofitting modern, high-efficiency Dometic, Webasto, and MarinAire units in place of older systems. An upgrade can provide better cooling, lower power consumption, and quieter operation. It's a night-and-day difference from what the old salts were used to.
Where is the best place to install the A/C unit and air handlers?
Placement is key for performance and comfort. The main unit often goes in the engine room or a dedicated mechanical space. Air handlers are strategically placed in cabins and the salon to provide even airflow without creating drafts. We plan the ducting runs to be as short and direct as possible, avoiding sharp bends that restrict airflow.
Do you handle the electrical and plumbing for the installation?
Yes, we provide a complete, turnkey installation. This includes all 12V/24V DC and 120V/240V AC electrical wiring, seawater intake and discharge plumbing, and condensate drains. We ensure every part of the system is installed to ABYC standards for safety and reliability, so you don't have to worry about a thing.
