Your fridge holds temp through July heat. Your AC doesn’t kill your batteries by noon. You’re not calling for emergency repairs every other weekend.
That’s what happens when someone who knows marine systems does the work right the first time. Marine refrigeration isn’t the same as residential HVAC—the constant motion, saltwater exposure, and limited power supply create challenges that most contractors have never dealt with. Your boat needs components designed for the marine environment, proper installation that accounts for vibration and corrosion, and a system calibrated for efficiency when you’re running on battery power.
When your system works correctly, you stop worrying about it. Your provisions stay cold during long weekends. Your cabin stays comfortable without draining power. You actually enjoy your time on the water instead of troubleshooting temperature swings and listening to your compressor cycle constantly.
Chill Xpert Solutions has been handling marine HVAC and refrigeration systems for over 40 years. We serve boat owners throughout Northwest Harbor, Three Mile Harbor, and the broader East Hampton area with the same expertise we bring to commercial clients across airports, restaurants, and catering facilities.
The difference shows in how we approach marine work. We understand that your boat’s cooling system faces conditions no land-based unit ever sees—saltwater spray, constant movement, marine growth in water lines, and the need to run efficiently on limited power. We’ve seen what fails and why, and we know how to install and maintain systems that actually last in the harsh marine environment.
When you’re dealing with a refrigeration emergency during peak boating season, you need someone who answers the phone and shows up. We offer 24/7 consulting and free estimates because we know your time on the water matters.
You call with a problem—your fridge isn’t holding temperature, your AC is blowing warm air, or your system is cycling too frequently and draining batteries. We start with a real diagnostic assessment, not guesswork. We check refrigerant levels, test components, inspect for leaks, and evaluate whether your system is sized correctly for your vessel and power supply.
If it’s a repair, we handle it with marine-grade parts designed for saltwater environments. If your system needs replacement or upgrade, we’ll recommend options that match your boat’s specific needs and power capacity. We account for proper ventilation, secure waterproof connections, adequate insulation, and placement that works with your vessel’s layout.
Installation isn’t rushed. Marine refrigeration requires attention to details that matter—ensuring raw water strainers are accessible, routing lines to minimize vibration damage, using proper anti-corrosion materials, and calibrating controls for efficient operation. Once the system is running, we verify it’s performing correctly before we leave your dock. You get a system that works the way it should, installed by people who understand why marine applications are different.

Marine refrigeration service covers everything your boat’s cooling systems need to function reliably. That includes refrigerators, freezers, ice makers, air conditioning units, and chiller systems. Whether you’re running a simple icebox conversion or a complex multi-zone climate control setup, the work requires someone who understands marine-specific components like BD35 compressor controllers, water-cooled condensers, and evaporator plates designed for constant motion.
In Northwest Harbor and the surrounding East Hampton waters, your marine systems face particular challenges. Summer heat pushes AC units hard. Saltwater from Gardiner’s Bay accelerates corrosion. Marine growth clogs strainers and water lines, especially during the most active summer months when you’re using your boat most. Regular maintenance—checking strainers every few weeks, inspecting filters monthly, cleaning condensers, and testing refrigerant levels—prevents the breakdowns that ruin weekends.
We handle installations for new systems, retrofits for aging equipment, emergency repairs when something fails, and preventive maintenance to keep everything running. We work on all brands and all types of boat refrigeration and air conditioning systems. If you need a custom solution—whether that’s upgrading to a more efficient system, adding capacity, or designing cooling for a unique layout—we have the experience to build it correctly. The goal is simple: your boat’s refrigeration and AC should work without you thinking about it.
Repair costs depend entirely on what’s actually wrong with your system. A simple fix like replacing a failed thermostat or cleaning clogged strainers might run a few hundred dollars. More involved repairs—fixing refrigerant leaks, replacing compressors, or rebuilding condensers—typically cost more because they require marine-grade components and specialized labor.
The real cost isn’t just the repair itself. It’s what happens when someone without marine experience tries to fix your system with the wrong parts or improper techniques. You end up paying twice—once for the failed repair and again when you need someone who knows what they’re doing. We provide free estimates so you know exactly what you’re looking at before any work begins. We’ll tell you honestly whether repair makes sense or if replacement is the smarter investment for your situation.
Marine refrigeration systems operate in an environment that destroys regular refrigeration equipment. Your boat moves constantly, creating vibration that loosens connections and stresses components. Saltwater spray corrodes everything it touches. You’re running on limited battery power instead of unlimited shore power. The cooling system has to work efficiently or it drains your batteries dead.
The components are different too. Marine compressors are designed to handle motion and operate on 12V or 24V DC power. Condensers use seawater for cooling instead of air, which means they need raw water pumps, strainers, and anti-fouling treatments. Insulation requirements are more demanding because you’re fighting heat and humidity in a confined space. Even simple things like thermostats need to be calibrated differently because marine refrigerators can’t cycle the same way residential units do without killing your batteries.
This is why hiring someone who actually works on boats matters. A regular HVAC technician might understand refrigeration principles, but they don’t know how to size a system for limited power, prevent galvanic corrosion, or install components that won’t fail when your boat is pounding through waves. Marine refrigeration is its own specialty.
Marine air conditioning systems need more frequent attention than anything in your house because they run continuously and draw raw water constantly. At minimum, you should have a professional service check at the start and end of each boating season. During active use, you need to stay on top of basic maintenance yourself—checking and cleaning raw water strainers every few weeks, inspecting return air filters monthly, and watching for any changes in performance.
Summer months in Northwest Harbor are when marine growth is most active. Barnacles, algae, and biofilm grow in your raw water lines and heat exchangers, restricting flow and killing efficiency. If you notice your AC running longer, not cooling as well, or throwing high pressure faults, it’s usually because something is clogged. Waiting until complete failure costs more than preventive maintenance.
A proper service includes cleaning strainers and sea strainers, inspecting drain lines, checking electrical connections, testing refrigerant levels, cleaning evaporator coils, and verifying the system is operating at proper capacity. We can set up a maintenance schedule that makes sense for how you use your boat. Regular service prevents the emergency breakdowns that happen on the hottest weekend of summer when every marine technician is booked solid.
Yes. We service all major brands of marine refrigeration and air conditioning equipment—Dometic, Cruisair, Marine Air, Frigoboat, Vitrifrigo, Isotherm, Sea Frost, Grunert, Webasto, and everything else you’ll find on boats in this area. We also handle custom-built systems and specialty installations that don’t fit standard configurations.
Experience with multiple brands matters because different manufacturers use different components, control systems, and installation requirements. What works for troubleshooting a Dometic unit isn’t the same approach you’d use for a Frigoboat system. Having 40+ years in the industry means we’ve seen most problems before and know the common failure points for different equipment.
If your system is older or discontinued, we can often retrofit modern components or source parts that keep it running. If replacement makes more sense, we’ll recommend options that fit your boat’s power capacity, space constraints, and cooling needs. The brand on your current equipment doesn’t limit what we can do—we work with what you have or help you upgrade to something better.
The most common culprits are refrigerant leaks, failed compressors, clogged condensers, and thermostat problems. Refrigerant leaks usually develop at connection points that vibrate loose or corrode over time. You’ll notice the fridge running constantly but not maintaining temperature. Low refrigerant means the system can’t transfer heat effectively, and the compressor works harder trying to compensate.
Compressor failure happens from age, overwork, or improper voltage. Marine compressors are designed for DC power, but if your batteries are weak or your charging system isn’t keeping up, the compressor struggles and eventually burns out. Clogged condensers are common in saltwater environments—marine growth, calcium deposits, and debris restrict water flow through the heat exchanger, so the system can’t reject heat properly. Thermostats fail from moisture, corrosion, or simple wear, causing temperature swings or preventing the system from running at all.
Power consumption issues can also make it seem like your fridge isn’t working. If your system is oversized, poorly insulated, or has air leaks around the door seals, it will run constantly and drain your batteries before it can maintain proper temperature. Sometimes the refrigerator itself is fine, but the installation was wrong from the start. A proper diagnostic figures out what’s actually broken versus what was never set up correctly in the first place.
Yes. We provide 24/7 consulting and emergency service because marine refrigeration problems don’t wait for business hours. When your system fails on a Friday afternoon before a long weekend, or your AC quits during a July heat wave, you need someone who actually answers and can respond.
Emergency service means we prioritize getting you back up and running. We carry common marine refrigeration parts and components so simple repairs can be completed on the spot. For more complex issues, we’ll diagnose the problem, explain your options, and work with you on the fastest solution that makes sense. Sometimes that’s a temporary fix to get you through the weekend with a permanent repair scheduled for later. Sometimes it’s a same-day replacement if your system is beyond saving.
The key difference is availability and expertise. A lot of HVAC companies claim they do marine work, but they don’t keep marine parts in stock and their technicians don’t really understand boat systems. When you call us, you’re reaching people who have spent decades working on marine refrigeration and air conditioning. We know what fails, we know how to fix it, and we show up when you need us.
