Not Just Another Climate System
SeaAir isn’t an air-conditioning company trying to catch up with technology—we’re a technology company redefining
marine air conditioning. We build smarter systems for a world that’s been stuck too long in the past. We’re the
innovators and disrupters bringing modern intelligence, connectivity, and design to marine climate control—because
your boat deserves more than the same old HVAC box.
Behind every SeaAir system is precision, performance, and
purpose. We don’t cut corners—we partner with the best. Our variable-speed compressor from Boyard is proven across
millions of units worldwide for reliability and efficiency. We use quality breakers and terminal blocks built by
reputable, well-known brands to ensure bulletproof electrical integrity—trusted by mariners everywhere.
Every
unit is built for strength, performance, and silence. At its heart is a whisper-quiet rotary compressor, mounted on
rubber isolation feet to absorb vibration and deliver quiet operation. That compressor feeds an oversized condenser
made with titanium coils in a copper jacket, engineered for unmatched durability in harsh marine environments. Each
machine is fitted with an oversized evaporator that ensures superior cooling performance even in the hottest, most
demanding climates. A sleek aluminum housing enhances aesthetics while dampening sound and a condensate pan neatly
collects condensate. Corrosion-proof plastic retaining feet keep the foundation solid for years to come—built to
perform beautifully, season after season.

Frequently Asked Questions
How much space can the ac system cool?
What makes SeaAir's marine air conditioner different from other systems?
Can I run it on battery or solar power?
Yes, you can. SeaWater Pro offers a 12V DC-powered marine A/C system specifically designed to operate efficiently on battery banks or solar systems. This makes it a perfect solution for boats without a generator or for those who want to reduce reliance on shore power. No soft start required and variable speed operation helps conserve energy.
What size marine air conditioner do I need for my boat?
The appropriate size depends on your cabin’s square footage, insulation, and ventilation. As a general guide:
- 5,000 BTU for cabins up to ~100 sq ft
- 9,000–12,000 BTU for 100–250 sq ft
- 12,000+ BTU for large salons or combined spaces
The Seawater Pro 12 volt DC Marine Air conditioner is capable of operating at 5,000, 9,000, and 12,000 BTU modes. You can select the appropriate setting for the space in which it will be installed. This setting is chosen through the Pro Display control.
Is the SeaAir A/C compatible with my watermaker?
The water maker and air conditioner systems are independent of one another. They are both designed for efficiency in easy use, making them complementary to each other.
How does it work?
Our systems use a reverse-cycle refrigeration process. The unit absorbs heat from your cabin and transfers it into seawater via a heat exchanger. In heating mode, the process is reversed to warm the air. The result is quiet, efficient climate control for year-round comfort.
Can I install the system myself?
Yes. SeaWater Pro’s systems are DIY-friendly and come with detailed installation instructions. Most installations require basic plumbing and electrical knowledge. If you're not comfortable with marine systems, professional installation is always a good option.
How quiet is the unit?
Our units are engineered for quiet operation using soft-start brushless DC compressors and variable speed technology. They are significantly quieter than older compressor-based units, making them ideal for sleeping cabins or enclosed pilothouses. The system components are housed in a a powder-coated aluminum cladding, creating a sound barrier.
Can I use my A/C while underway?
Yes. As long as the unit is powered and the seawater intake is unobstructed, the A/C can run while underway. This is especially useful for cooling cabins before anchoring or while traveling in hot climates.
What is the power draw of the 12V unit?
Power usage varies depending on the model and speed setting. A 12V 12,000 BTU unit may draw around 50–70 amps at peak, but soft-start and speed control features allow for significant energy savings. Our system is optimized for solar and lithium battery applications. For a sleeping cabin, we’ve measured average 250 amp hour use over night in 5,000 BTU mode.
Does the system include heating?
Yes, all SeaWater Pro marine air conditioners are reverse-cycle, which means they provide both cooling and heating. You can switch between modes using the Pro Display control, making it suitable for all climates.
How do I maintain my marine air conditioner?
We recommend:
- Cleaning the seawater strainer regularly
- Rinsing or replacing air filters every few months
- Inspecting ductwork and condensate drain lines
- Winterizing the system with propylene glycol during the off-season
Routine checks help extend the life of your system and ensure peak performance.
What is the lifespan of the unit?
With proper care and regular maintenance, our marine A/C units typically last 8–15 years. Saltwater exposure and usage patterns can affect lifespan, but our systems are built with high-quality, corrosion-resistant components for longevity.
Can I retrofit this A/C system into my existing boat?
Yes. Our compact, modular units are ideal for retrofits. Flexible ducting and simplified power requirements make it easy to install in older vessels without major modifications.
What’s included with the system?
Each SeaWater Pro marine A/C unit includes:
- The main 12V DC air conditioning unit
- Programmable Pro Display control
- Single stage 12 volt seawater pump
- Basic installation manual
- Temperature sensor
Component mounting board
- Computer control
- Compressor control
- 80 amp Blue Sea Systems breaker
- 4 Circuit 65 amp Blue Sea Systems Terminal Block
