Our compact marine air conditioners are designed to fit tight spaces—checking technical specifications ensures the perfect match.
There is no single “one-size-fits-all” seawater pump for marine air conditioners. The correct pump size depends on three factors: the air-conditioning unit, your specific installation, and the pump’s performance characteristics.
Each model lists a “Water Flow” value in the Technical Specifications tab. This rating refers to the required water flow at the unit outlet, not the pump size itself.
Because water flow is reduced by hose length, fittings, and vertical lift (head pressure), the pump selected must be capable of delivering the required flow at your actual installation head. Always reference the pump’s performance curve to confirm this.
(Assumes average hose lengths and typical installations)
If you are running more than one air conditioner:
Tip: If your installation involves unusually long hose runs, multiple elevation changes, or shared manifolds, consult the pump flow curve or a marine HVAC professional to ensure proper sizing.
We know space on any marine vessel is limited and valuable! Our units are designed to be among the most compact in their class, but every installation space is different. Always measure your available space before purchasing.
Refer to the “Dimensions & Drawings” tab under each model for exact measurements, including overall size and service clearances. Confirm that there is adequate room not only for the unit itself, but also for hose connections, wiring, airflow, and future maintenance access.
Tip: If your space is tight or irregularly shaped, reviewing the dimensional drawings before ordering can help avoid installation issues.
That depends on your specific installation.
Each unit is pre-charged, and includes the core components required to operate the system:
Installation-specific items — such as seawater pumps, plumbing components, ducting, venting, grilles, and fittings — vary by vessel and layout and are not included. These items must be selected separately based on your setup.
If you are replacing an existing marine air-conditioning unit, most installations can reuse the existing set up.
Many customers refer to this as a ‘plug-and-play’ replacement.
No. These units are designed exclusively for marine applications and are not supported for use outside of a marine environment.
Each marine air conditioner requires hundreds of gallons per hour of water flow from an open loop system. Water tanks, pools, tubs, etc. will not work.
They are also not UL-listed for use outside of a marine environment and are not approved for non-marine installations.
Generator size depends on your specific MarinAire model, voltage, and what other onboard loads you plan to run at the same time. We recommend consulting a qualified marine electrician for final generator selection and installation. For a quick starting point, you can use our Generator Size Calculator, which provides a general estimate based on your unit and rounds to common real-world generator sizes.
You can run MarinAire on DC (battery) power by using a pure sine wave inverter to convert your battery bank’s DC into AC power. Because inverter sizing, wiring, and battery performance vary by installation, we strongly recommend consulting a qualified marine electrician for accurate system design and verification. If you’d like a starting point, our Battery Power Calculator can provide a general estimate of inverter size and expected runtime based on your unit and battery setup, but results may vary in real-world conditions.
MarinAire is an American company, and our systems are invented and engineered in the United States.
Our air conditioners are built using hundreds of globally sourced components from top quality manufacturers, with parts produced in multiple countries (Japan, Germany, etc.) to meet performance and reliability standards. Final assembly is performed in China, followed by multi-stage testing and quality verification.
Before shipment, each unit undergoes final inspection and quality control in the United States to ensure it meets our performance, safety, and reliability standards.
"I would have liked to had a choice of color on the thermostat cover. But all is good for now."
"Thank you."
Works better than the 16k Dometic unit it replaced
Delivered promptly. Very good customer service when I called to trouble shoot.
EXCELLENT
Super fast shipping. The call after online order for questions was over and above expectations.
super fast shipping at a good buy.
I installed this unit and it is working perfectly. I will have to say that I've got to put two more of them in pretty shortly to replace the old ones and our motor yacht. The people at this company are very very great to deal with have not one complaint whatsoever. Keep the good work up you got two more orders to fill for me soon as I get them put in.
Ordered the 11,000 BTU and water pump. All was delivered on time, and the installation went on without any problems. Had a couple of questions and called the help line. They were very helpful.
All set for the summer in Southeastern Texas.
Thanks!
The air conditioner is great. Very easy to install. Cools the whole bowl And is very quiet. Would be five stars but they use FedEx for delivery And the delivery service sucks. So if you can have them, use a different carrier to deliver your unit.
I replaced the original unit on my 1988 Carver with the 11k unit and am so impressed. Install was easier than I expected and it is super quiet and cold! Strong recommend.
Marinaire is the best company I’ve dealt with in years. They called to make sure it was going to fit. I can understand that they said it would be here Monday or Tuesday and came here Sunday, like wow! I don’t need any more marine air conditioners at this time but if I did, I would go to marinairs in a second!
Thanks you all!
absolutely easy installation, color photos replaced the unit in about an hour.
ordering another to replace an older unit.
Order process was good, communication was good and shipping was excellent
THIS UNIT APPEARS TO BE HIGH QUALITY. WE WILL KNOW MORE ONCE WE GET IT INSTALLED
I received my unit quickly and very well packaged. Installation was easy because piping and electrical connections are located very similar to the equipment being replaced. The unit is very quiet, the only time I hear the compressor is when it starts, and only if I’m listening for it. The fan is powerful and quiet, and moves air around the boat much better than my original units. I installed in a 1991 Carver aft cabin, at 30 years old, it was overdue for the upgrade. It would be great to have decorative plates to cover where the old thermostats as an optional purchase, as well as adapters to connect multiple ducts…my original units had square flanged outputs, the new had round…I was able to fabricate adaptors with 6†duct caps pretty easily, but would have loved the option of purchasing with the units. Overall I’m very pleased with my purchase and have recommended the same to neighbors at the marina.
Have purchased before and As usual excellent service and super fast shipping.
Ordered it on a Tuesday night, and it was delivered in less than 48 hours with regular ground shipping. Wow, fast! Installed it over the weekend. This MarinAire 11,000 BTU unit is quieter than my previous 3 year old Dometic Envirocomfort 6,000 BTU unit that died, plus the MarinAire has significantly more airflow than the Dometic. It's simply amazing! I also bought a Cielo Breeze Eco AC Controller on Amazon for $82 and now I can control this air conditioner from anywhere using the Cielo app on my iPhone! I will ONLY replace my existing (Dometic) air conditioning units with MarinAire when they (the Dometic) fail...which seems way too often.
You have to give MarinAire a try!
Could not be happier. Had originally ordered one from someone else and was over a month and still no shipping. Cancel the order and made orders with MarinAir and was here in 5 days.. Absolutely perfect condition.. Thanks again..
"will this be back customer service rep told me its been discountinued for many years"
"Works great and the people that work there are great to deal with and good people! I will definitely keep useing them and their products!"
"We recently replace a main salon unit with a Marinaire unit and found it exceeded our expectation. The compressor is near silent, the only way we know the unit is running is due to the fan and airflow. Delivery was with 3 days of order and dimension were as advertised making our installation go as planned. All our future units will be Marinaire."
"Sam did very good - thanks"
"Nice little unit. Was shipped very quickly. Works well but documentation could be a bit better. Only real issue I had was that the existing "phone type" cable that runs to the control panel. would not work with the new system. Would have thought that it would be plug and play as the jacks matched up and a wire should be a wire? But other than that would buy one again."
"My yacht construction & repair specialist, and myself are very impressed with the features of these units. A quality compressor, Gauges installed to monitor pressure, easy refill access, Stainless drip pan, and ease of installation.
The included phone cord was inop. right out of the box. (connects to the control panel) Not a big deal. I'm extremely happy with the unit. "
Placed order on a Saturday, received a confirmation phone call on Monday, received the A/C unit on Wednesday, Included everything I needed (Except ductwork) to complete the install. Works great and we're happy with the purchase!
Delivery prompt and professional. We were given a courtesy call to confirm the order before it shipped. We received the units in 2 days. The units are quality and easy to install with a rotating plenum. The only downside was needing to adapt the size of the ductwork.
Have not had the time yet to install the units and components,, everything arrived as planned. Well packaged and secure. Will be installing, hopefully, in the very near future. Hoping all will fit comparatively to the cruisair units I am replacing.
This is the second unit I purchased this month. I have nearly 20 yesr old salt water boat. A/C units were well packaged, installed in place of old Marineaire units. First one wa under a bunk took 9 hrs, second one 3 hours. Nice looking, worked right out of the box and delivery was quick. Very pleased. Very quiet tooðŸ‘ÂÂÂ
"The unit came in just as it said it would all looked good. Will be installing it Friday 2-14."
