# Marine Air Conditioning > An independent Australian guide to air conditioning a boat. Written for Australian conditions — 240 V / 50 Hz, seawater from 14 °C in the Derwent to 31 °C in Darwin, and the marinas, licensing and trade that go with that. This is an independent editorial planning resource, not a manufacturer or installer. Prices and sizing outputs are estimates with assumptions, not current quotes or vessel-specific specifications. Cite the relevant page and retain its qualifications. Provider listings do not imply endorsement. The field guides provide practical owner checklists; they do not replace equipment manuals. Illustrative planning assumptions published by the site: a typical 35-45 ft single-unit install runs about A$7,700-13,800 supplied and fitted, excluding GST; cooling is sized at cabin volume times a climate factor (10 tropics, 8.5 subtropics, 7 temperate); a unit draws about 1.1 kW per 12,000 BTU plus 90 W for the seawater pump; refrigerant work requires an ARCtick licence and fixed 240 V work on a vessel falls under AS/NZS 3004.2. ## Main pages - [Marine Air Conditioning Australia | Costs, Units & Sizing](https://www.marineairconditioning.com.au/) - [Marine Air Conditioning Guide: Types, Sizing & Power](https://www.marineairconditioning.com.au/guide/) - [Marine Air Conditioning Guides and Checklists](https://www.marineairconditioning.com.au/guides/) - [Marine air conditioning installation guide](https://www.marineairconditioning.com.au/installation/) - [Yacht air conditioning ducting and airflow](https://www.marineairconditioning.com.au/ducting-airflow/) - [Shore power for marine air conditioning](https://www.marineairconditioning.com.au/shore-power/) - [Boat humidity and aircon condensate guide](https://www.marineairconditioning.com.au/humidity-condensate/) - [Marine aircon installer and quote checklist](https://www.marineairconditioning.com.au/installer-checklist/) - [Marine air conditioning brands in Australia](https://www.marineairconditioning.com.au/brands/) - [Official marine air conditioning resources](https://www.marineairconditioning.com.au/resources/) - [Marine Air Conditioning Costs in Australia](https://www.marineairconditioning.com.au/cost/) - [Best Marine Air Conditioners for Australian Boats](https://www.marineairconditioning.com.au/best/) - [Compare Marine Air Conditioners | Types & Specifications](https://www.marineairconditioning.com.au/compare/) - [Marine Air Conditioning by Australian Location](https://www.marineairconditioning.com.au/ports/) - [Marine air conditioning FAQ for Australian boats](https://www.marineairconditioning.com.au/faq/) - [Contact Marine Air Conditioning | Boat Enquiries](https://www.marineairconditioning.com.au/contact/) - [Marine Air Conditioning How-To Guides for Boat Owners](https://www.marineairconditioning.com.au/how/) - [Marine air conditioning troubleshooting — 20 faults](https://www.marineairconditioning.com.au/faults/) - [Marine Air Conditioning Sizing | Boat BTU Calculator](https://www.marineairconditioning.com.au/sizing/) - [Marine air conditioning glossary](https://www.marineairconditioning.com.au/glossary/) - [Marine air conditioning maintenance and servicing](https://www.marineairconditioning.com.au/maintenance/) - [Marine Air Conditioning Installers in Australia](https://www.marineairconditioning.com.au/installers/) - [Marine Air Conditioning Sitemap | All Website Pages](https://www.marineairconditioning.com.au/sitemap/) ## Marine air conditioning how-to questions and answers Every answer below is the complete answer as published, each on its own page at https://www.marineairconditioning.com.au/how/. Marked up as FAQPage or HowTo structured data. ### Choosing - **How do I choose between self-contained, split and chilled water?** — Compare the cabins to be cooled, available equipment spaces, duct or pipe routes and power supply. Self-contained systems package the refrigeration circuit together; splits separate components; chilled water distributes cooling through a freshwater loop. Cabin count helps define the brief, but it does not by itself determine the correct architecture. [https://www.marineairconditioning.com.au/how/choose-between-the-three-systems/](https://www.marineairconditioning.com.au/how/choose-between-the-three-systems/) - **How do I decide between one big unit and two small ones?** — Compare the required cooling in each occupied zone and the duct routes available. One unit may cost less, while two units can offer independent operation and some redundancy. Neither total BTU nor boat length alone proves that air can reach both cabins adequately. [https://www.marineairconditioning.com.au/how/one-big-unit-or-two-small/](https://www.marineairconditioning.com.au/how/one-big-unit-or-two-small/) - **How do I pick a unit that will fit the locker I have?** — Measure the locker before you shortlist anything. Self-contained units need clearance for the blower discharge and the return air as well as the box itself, plus room to get a hand to the strainer and the electrical connections. A unit that fits the hole but cannot be serviced is a decision you will regret slowly. [https://www.marineairconditioning.com.au/how/pick-a-unit-that-fits/](https://www.marineairconditioning.com.au/how/pick-a-unit-that-fits/) - **How do I decide if reverse cycle heating is worth it?** — Check whether the exact unit provides reverse-cycle heating and whether its performance matches the seawater temperatures you expect. Heating at a powered marina berth is a different requirement from heating at anchor. Compare available electrical energy and seasonal use before relying on it as the boat’s only heat source. [https://www.marineairconditioning.com.au/how/decide-if-heating-is-worth-it/](https://www.marineairconditioning.com.au/how/decide-if-heating-is-worth-it/) - **How do I decide between fitting now and waiting for the next refit?** — Wait if the headliner or the joinery is coming down anyway. Ducting, wiring and insulation are dramatically cheaper when the boat is already open, and retrofitting a duct run behind finished joinery is where a quote gets expensive. Fit now if you are about to spend a summer aboard without it. [https://www.marineairconditioning.com.au/how/fit-now-or-at-the-next-refit/](https://www.marineairconditioning.com.au/how/fit-now-or-at-the-next-refit/) ### Sizing and power - **How do I work out how many BTU my boat needs?** — Take the accommodation volume and multiply by a climate factor: 7 for temperate water, 8.5 for the subtropics, 10 for the tropics. Add about ten per cent for a dark hull and another ten for a lot of glass. A 40 ft boat lands near 13,000 BTU in Sydney and 18,500 in Darwin. [https://www.marineairconditioning.com.au/how/work-out-how-many-btu/](https://www.marineairconditioning.com.au/how/work-out-how-many-btu/) - **How do I size air conditioning for a catamaran?** — Assess each hull and the bridgedeck saloon as separate cooling zones using their dimensions, glazing and occupancy. A length-based monohull estimate may understate a catamaran’s accommodation and solar load. Choose equipment after checking zone loads and routes, rather than adding a universal percentage to boat length. [https://www.marineairconditioning.com.au/how/size-for-a-catamaran/](https://www.marineairconditioning.com.au/how/size-for-a-catamaran/) - **How do I account for a dark hull when sizing?** — Record hull and deck colour, exposed glazing and available shade when sizing marine air conditioning. This site’s calculator adds an illustrative ten per cent allowance for a dark hull; actual solar gain depends on construction, insulation, orientation and shading. Have the installer assess the real spaces instead of applying the allowance as a design rule. [https://www.marineairconditioning.com.au/how/account-for-a-dark-hull/](https://www.marineairconditioning.com.au/how/account-for-a-dark-hull/) - **How do I size for the tropics versus temperate water?** — Use the warmest realistic cruising conditions in the design brief, including seawater temperature, humidity and solar load. The site’s tropical and temperate factors are planning assumptions, not manufacturer derating curves. Check the selected unit’s actual output at the intended conditions before ordering a larger capacity. [https://www.marineairconditioning.com.au/how/size-for-tropics-versus-temperate/](https://www.marineairconditioning.com.au/how/size-for-tropics-versus-temperate/) - **How do I work out what it will draw on a marina lead?** — Reckon on 1.1 kW for every 12,000 BTU plus about 90 W for the seawater pump. A 16,000 BTU system is roughly 1.56 kW, or 6.5 A at 240 V — which leaves 3.5 A of a 10 A marina lead for the charger, the kettle and everything else aboard. [https://www.marineairconditioning.com.au/how/what-it-draws-on-a-marina-lead/](https://www.marineairconditioning.com.au/how/what-it-draws-on-a-marina-lead/) - **How do I run air conditioning at anchor?** — Three routes: a generator, a large lithium bank with an inverter, or a 12 V DC unit that skips the inverter entirely. All three are a real investment. A 16,000 BTU system pulls about 1.56 kW, so a night of cooling is roughly 9–11 kWh once you allow for the duty cycle. [https://www.marineairconditioning.com.au/how/run-it-at-anchor/](https://www.marineairconditioning.com.au/how/run-it-at-anchor/) - **How do I size a battery bank to run air conditioning overnight?** — Estimate the energy for the intended cooling period, add other onboard loads and allow for inverter losses where applicable. Divide by the battery capacity you can actually use while retaining reserve. Check continuous current, compressor starting demand and the charging plan separately: enough stored kWh does not guarantee the system can start. [https://www.marineairconditioning.com.au/how/size-a-battery-bank/](https://www.marineairconditioning.com.au/how/size-a-battery-bank/) - **How do I stop the air conditioning tripping a 10 A marina lead?** — Record which protective device trips and whether it happens during compressor start or sustained operation. Reduce optional loads within the boat’s approved operating plan and arrange checks by the marina or a licensed electrician. Repeated trips can indicate a fault; they are not a reason to bypass protection or repeatedly reset it. [https://www.marineairconditioning.com.au/how/stop-it-tripping-a-10-amp-lead/](https://www.marineairconditioning.com.au/how/stop-it-tripping-a-10-amp-lead/) - **How do I work out the running cost per night?** — Multiply electrical input in kW by the hours each load runs, then multiply total kWh by the electricity tariff actually charged at your berth. Treat compressor duty cycle and pump operating time separately. A quoted BTU cooling capacity is not the electrical input to use in the calculation. [https://www.marineairconditioning.com.au/how/work-out-the-running-cost/](https://www.marineairconditioning.com.au/how/work-out-the-running-cost/) - **How do I decide whether I need a soft start?** — Ask the manufacturer or installer whether an approved soft-start device suits the exact compressor and controller. Compare its starting requirements with the available supply or inverter. A soft start can reduce starting demand on compatible equipment, but it cannot repair an electrical fault or increase the permissible running load. [https://www.marineairconditioning.com.au/how/decide-whether-i-need-a-soft-start/](https://www.marineairconditioning.com.au/how/decide-whether-i-need-a-soft-start/) ### Installing - **How do I plan the seawater side before anything else?** — Work out where a new skin fitting can go below the waterline, where a strainer can sit high enough to be opened but low enough to stay primed, and where the pump can live below the waterline. Everything else — unit position, ducting, drain — follows from those three points. [https://www.marineairconditioning.com.au/how/plan-the-seawater-side/](https://www.marineairconditioning.com.au/how/plan-the-seawater-side/) - **How do I choose where the unit goes?** — Choose a dry, accessible location that meets the manufacturer’s airflow, drainage, mounting and service-clearance requirements. Consider noise at sleeping positions and the routes for ducts, power and seawater hoses. The seawater pump’s flooded-suction requirement does not mean the air-conditioning unit itself must sit below the waterline. [https://www.marineairconditioning.com.au/how/choose-where-the-unit-goes/](https://www.marineairconditioning.com.au/how/choose-where-the-unit-goes/) - **How do I route ducting so both cabins actually cool?** — Have the installer size the supply and return paths for both cabins using the equipment airflow requirements. Keep duct runs appropriately sized and supported, with gentle bends where possible. Check performance with doors in their normal sleeping positions; do not restrict one outlet by guesswork to force air into another. [https://www.marineairconditioning.com.au/how/route-ducting-so-both-cabins-cool/](https://www.marineairconditioning.com.au/how/route-ducting-so-both-cabins-cool/) - **How do I get the condensate to drain properly?** — A continuous gravity fall from the drip tray to a sump or shower drain — never to the bilge. A 16,000 BTU unit pulls litres a day out of humid air, and any rise, sag or loop in the hose holds water and backs the tray up until it overflows. [https://www.marineairconditioning.com.au/how/get-the-condensate-to-drain/](https://www.marineairconditioning.com.au/how/get-the-condensate-to-drain/) - **How do I fit a through-hull and seacock for air conditioning?** — Have a marine installer assess the intake position, seacock accessibility, materials, hose support and required seawater flow. Below-waterline fittings need a suitable design and installation method for the hull. Do not assume an existing intake can be shared or drill the hull from a generic checklist. [https://www.marineairconditioning.com.au/how/fit-a-through-hull-and-seacock/](https://www.marineairconditioning.com.au/how/fit-a-through-hull-and-seacock/) - **How do I wire marine air conditioning to Australian standards?** — You do not — a licensed electrician does. Fixed 240 V wiring on a vessel falls under AS/NZS 3004.2, and it needs a dedicated circuit, an RCD and correctly rated cable. Budget $300–800 in materials plus three to six hours of licensed labour. [https://www.marineairconditioning.com.au/how/wire-it-to-australian-standards/](https://www.marineairconditioning.com.au/how/wire-it-to-australian-standards/) - **How long does a marine air conditioning installation take?** — Fifteen to twenty-five yard hours for a single self-contained unit on a 35–45 ft boat — typically two to four days in the yard. A two-zone split runs twenty-five to forty hours, and a chilled-water system with three or four zones is a week or more. [https://www.marineairconditioning.com.au/how/how-long-installation-takes/](https://www.marineairconditioning.com.au/how/how-long-installation-takes/) - **How do I prepare the boat before the installer arrives?** — Empty every locker the work touches, take out anything soft that will absorb fibreglass dust, and confirm in writing where the unit sits, where the grilles go and where the condensate drains. An hour of clearing saves an hour of yard labour at $110–140. [https://www.marineairconditioning.com.au/how/prepare-before-the-installer-arrives/](https://www.marineairconditioning.com.au/how/prepare-before-the-installer-arrives/) - **How do I add a second zone to an existing system?** — Usually a second self-contained unit sharing the existing seawater loop, which is far cheaper than the first because the through-hull, pump and electrical work already exist. Extending ducting from the original unit is the tempting alternative and it is usually how one cabin ends up short. [https://www.marineairconditioning.com.au/how/add-a-second-zone/](https://www.marineairconditioning.com.au/how/add-a-second-zone/) ### Running and maintaining - **How do I get the most out of the system I have?** — Close the boat up, shade the deck and the glass, set the thermostat to 22–24 °C rather than 16, and wash the return-air filter monthly through summer. Those four cost almost nothing and together they do more than a size up would. [https://www.marineairconditioning.com.au/how/get-the-most-from-the-system-i-have/](https://www.marineairconditioning.com.au/how/get-the-most-from-the-system-i-have/) - **How often should I service marine air conditioning?** — Strainer monthly through summer, more often in silty water. Filter monthly. Condensate drain flushed annually. Condenser descaled every year in the tropics and every two or three further south. A full service check annually, before the season rather than during it. [https://www.marineairconditioning.com.au/how/how-often-to-service/](https://www.marineairconditioning.com.au/how/how-often-to-service/) - **How do I stop the boat smelling musty?** — Run the fan alone for ten minutes after cooling, so the coil dries before shutdown. Then wash the filter, clean the drip tray and flush the condensate drain. The smell is biological, it lives in standing water in the tray, and drying the coil is what prevents it recurring. [https://www.marineairconditioning.com.au/how/stop-the-boat-smelling-musty/](https://www.marineairconditioning.com.au/how/stop-the-boat-smelling-musty/) - **How do I keep the cabin dry rather than just cold?** — A cold but clammy cabin may have high moisture entry, unsuitable controls, short cycling or airflow problems. Check the controller’s humidity instructions and record room temperature and humidity together. Raising the thermostat does not automatically lengthen compressor operation or improve dehumidification. [https://www.marineairconditioning.com.au/how/keep-the-cabin-dry/](https://www.marineairconditioning.com.au/how/keep-the-cabin-dry/) - **How do I run it efficiently to cut the power bill?** — Reduce avoidable heat gain and keep the installed system operating as specified. Shade exposed glazing, close openings while cooling occupied spaces and maintain clear airflow. Compare measured kWh under similar conditions before claiming savings from a setting or upgrade. [https://www.marineairconditioning.com.au/how/run-it-efficiently/](https://www.marineairconditioning.com.au/how/run-it-efficiently/) - **How do I look after it if the boat sits unused for months?** — Flush the seawater loop with fresh water, dry the coil with the fan, clean the drip tray, shut the seacock, and leave a hatch or a vent open if the boat is secure. A shut-up boat with a damp coil is where mould starts, and the fix afterwards is much harder than the prevention. [https://www.marineairconditioning.com.au/how/look-after-it-if-the-boat-sits-unused/](https://www.marineairconditioning.com.au/how/look-after-it-if-the-boat-sits-unused/) ### Diagnosing - **How do I tell if the problem is the seawater side or the refrigerant?** — Observe the seawater discharge and compare it with normal operation, then check accessible airflow restrictions. Weak or missing discharge points to a seawater-flow problem. Visible flow does not rule out a fouled condenser, inadequate flow or warm-water performance limits, and it does not prove a refrigerant fault. [https://www.marineairconditioning.com.au/how/tell-seawater-from-refrigerant/](https://www.marineairconditioning.com.au/how/tell-seawater-from-refrigerant/) - **How do I check the overboard discharge?** — Identify the correct discharge outlet and observe it during normal operation as described in the manual. Compare the flow with a known working baseline. Stop the system if discharge is absent or markedly reduced, and record the operating mode and any controller warning before arranging checks. [https://www.marineairconditioning.com.au/how/check-the-overboard-discharge/](https://www.marineairconditioning.com.au/how/check-the-overboard-discharge/) - **How do I tell if the unit is undersized or faulty?** — Compare current cooling with the boat’s previous performance under similar conditions. New loss of cooling suggests a fault or changed load; a system that has never met the design conditions may be undersized or poorly distributed. One supply-air temperature reading cannot establish the cause. [https://www.marineairconditioning.com.au/how/tell-if-undersized-or-faulty/](https://www.marineairconditioning.com.au/how/tell-if-undersized-or-faulty/) - **How do I check whether the seawater pump is working?** — Look for the expected seawater discharge and note unusual pump sound or visible leakage from a safe position. Stop the air conditioner if flow is absent. Do not touch potentially hot equipment, remove covers or open a seawater line while trying to identify the cause. [https://www.marineairconditioning.com.au/how/check-whether-the-pump-is-working/](https://www.marineairconditioning.com.au/how/check-whether-the-pump-is-working/) - **How do I know when to stop and call a technician?** — Stop and obtain professional help for burning smells, repeated protective-device trips, suspected seawater leaks, electrical faults or work on the refrigerant circuit. Owner maintenance is limited to tasks the manual permits and that you can carry out safely. Pumps and plumbing can involve electrical and flooding hazards even when refrigerant is untouched. [https://www.marineairconditioning.com.au/how/know-when-to-call-a-technician/](https://www.marineairconditioning.com.au/how/know-when-to-call-a-technician/) - **How do I test a system on a boat I am buying?** — Run it for a full hour, not five minutes. Check the overboard discharge, measure the air at every grille, look in the bilge for fresh water, find the strainer and see whether it is reachable, and ask for service records. An hour is long enough for a marginal system to reveal itself. [https://www.marineairconditioning.com.au/how/test-a-system-on-a-boat-i-am-buying/](https://www.marineairconditioning.com.au/how/test-a-system-on-a-boat-i-am-buying/) - **How do I tell if a previous install was done properly?** — Check four things: a dedicated through-hull rather than a tee into the engine intake, doubled marine-grade hose clamps below the waterline, a condensate drain going to a sump rather than the bilge, and a dedicated 240 V circuit with an RCD. Those four separate a proper job from a cheap one.
