Where is Ali Hassan Marine based and which areas do you serve?

Our head office is located at New Muwaileh, Office 4, Muwaileh Commercial Industrial Area, Sharjah, UAE. From this base we serve all major UAE locations including Dubai, Sharjah, Ajman, Fujairah, and Ras Al Khaimah. Our mobile teams can reach most locations within 1–2 hours for urgent calls, and we also attend vessels at all UAE ports and anchorages.

Are your technicians available 24 hours a day, 7 days a week?

Yes — our emergency response line is active 24 hours a day, 365 days a year. For marine vessel breakdowns, refrigeration failures, and AC emergencies we aim to have a technician on-site within 2 hours of your call. During standard business hours (Sunday to Thursday, 8 AM – 6 PM) our full office team is also available for non-urgent enquiries and quotations.

How do I request a quote or book a service visit?

You can reach us in three ways: call or WhatsApp us on +971 54 575 8205, email us at alihassanmarinellc@gmail.com, or fill in the contact form on our website at https://alihassanmarine.com/contact-us/. For emergency repairs, calling is always fastest. For new installations or planned work we recommend completing the online form so we can send the right engineer with the right equipment.

What types of marine refrigeration systems do you service?

We service all marine refrigeration system types found on commercial vessels, cargo ships, fishing fleets, and pleasure crafts. This includes provision refrigeration, fish hold cooling, reefer container units, provision store chillers, and full-vessel HVAC systems. We also carry out compressor overhauls for Sabroe, Bock, Bitzer, and Carlyle compressors commonly found on larger vessels.

Can you attend a vessel at anchor or underway in UAE waters?

Yes. We regularly attend vessels at Dubai, Sharjah, Hamriyah, Ajman, and Fujairah ports, as well as at anchorage positions in UAE waters. For vessels at anchor we can arrange launch transfer for our engineers. Please provide us with your vessel name, IMO number, anchorage position, and estimated stay duration when you call, so we can coordinate access efficiently.

Do you offer Annual Maintenance Contracts for vessels?

Yes. Our Annual Maintenance Contracts (AMC) for vessels include scheduled preventive maintenance visits (frequency tailored to your vessel's operational pattern), priority emergency response ahead of non-contract clients, discounted spare parts pricing, and full service reports after every visit. AMCs significantly reduce the risk of unexpected breakdowns and help vessel operators plan maintenance budgets accurately. Contact us at https://alihassanmarine.com/contact-us/ to discuss a contract tailored to your fleet.

My AC is running but not cooling — what could be wrong?

The most common causes are low refrigerant gas pressure (often due to a leak), a dirty or blocked condenser coil, a faulty compressor, or a blocked air filter. A fully charged but dirty AC can lose up to 30% of its cooling capacity without any obvious external sign. Our technician will run a full diagnostic on-site — checking gas pressure, electrical components, coil condition, and airflow — and identify the exact cause before quoting for any repair.

How often should I clean my AC ducts?

For residential properties we recommend professional duct cleaning every 12 to 18 months. For commercial buildings with high occupancy — offices, hotels, restaurants, hospitals — we recommend every 6 to 12 months. In dusty environments like construction sites or industrial areas, frequency should be increased. Signs you need an earlier clean include musty smells from vents, visible dust around registers, and increased allergy symptoms indoors.

What is VRV / VRF and is it suitable for my building?

VRV (Variable Refrigerant Volume) and VRF (Variable Refrigerant Flow) are names for the same technology — a single outdoor condensing unit connected to multiple indoor units (up to 64), each with independent temperature control. VRF systems are 30–40% more energy-efficient than conventional split AC systems at scale, making them ideal for offices, hotels, hospitals, and large commercial buildings. They are generally most cost-effective when you need to condition more than 5 separate zones. We provide free system design and load calculation — contact us at https://alihassanmarine.com/contact-us/ to discuss your project.

Which compressor brands do you stock spare parts for?

We maintain stock of genuine and high-quality equivalent spare parts for Sabroe, Bock, Bitzer, and Carlyle compressors — the most common brands found on commercial vessels and industrial systems in the region. For AC systems, we stock compressor parts for Daikin, LG, Samsung, Carrier, Trane, York, Gree, and Midea. If you need a part we don't currently hold in stock, we can source it rapidly through our international supplier network.

Are the spare parts you supply genuine OEM parts?

We supply genuine OEM (Original Equipment Manufacturer) parts wherever available. In some cases — particularly for older or discontinued models — we supply high-quality equivalent parts that meet or exceed the original manufacturer's specifications. We always clearly state which type of part we are supplying in our quotation, so you can make an informed decision. We never supply counterfeit or substandard parts.

How long does it take to source a spare part you don't have in stock?

For most common parts, if we don't have the item in our local warehouse we can source it within 2 to 5 working days through our UAE distributor network. For specialist or rare parts — such as components for older Sabroe reciprocating compressors — international sourcing typically takes 7 to 14 days depending on the manufacturer's location and current availability. We always advise on the expected lead time before you confirm an order.

Do you provide a warranty on your repair work?

Yes. All our repair work comes with a 30-day workmanship guarantee. If the same fault recurs within 30 days of our repair, we return and fix it at no additional charge — no arguments, no callout fee. For new installations we provide the full manufacturer's warranty on all equipment supplied, plus our own workmanship guarantee on the installation labour and pipework. Spare parts supplied carry a 12-month parts warranty.

Will I receive a quote before any work starts?

Always. We provide a clear, itemised written quotation before any work begins — covering parts, labour, and any materials. We never start a repair without your explicit approval of the price. For emergency callouts where a quick decision is needed, our technician will explain the fault and cost verbally on-site and confirm in writing. There are no hidden charges and no pressure to proceed with any work you are not comfortable with.

What does an Annual Maintenance Contract (AMC) include?

Our AMC packages are tailored to each client's needs but typically include: scheduled preventive maintenance visits (quarterly, bi-annual, or as agreed), priority emergency response over non-contract clients, discounted spare parts pricing (usually 10–20% below standard rates), detailed service reports after every visit, and a dedicated account contact. AMC clients also benefit from proactive advice on equipment that may need attention before it becomes an emergency.

Marine Refrigeration & HVAC Services in Fujairah Port

Ali Hassan Marine provides certified marine refrigeration, HVAC, and air conditioning services for vessels operating at Fujairah Port and the Khor Fakkan Container Terminal. Fujairah is one of the world’s busiest bunkering hubs — vessels anchored at Fujairah Offshore Anchorage or docked portside cannot afford system downtime. Our engineers mobilise from Sharjah and reach Fujairah locations within 3–4 hours for emergency callouts, with routine service appointments available across all days including weekends.

Our full service range is available to vessels and businesses in Fujairah:

Why We Serve Fujairah

Fujairah’s strategic position on the Gulf of Oman makes it one of the most important maritime locations in the region. The Port of Fujairah handles millions of tonnes of cargo annually, and the offshore anchorage at Fujairah routinely accommodates hundreds of vessels awaiting bunkering or transit. The high-salinity Gulf of Oman environment accelerates corrosion in marine refrigeration components, and the extreme summer heat increases mechanical stress on AC compressors and condenser coils. Ali Hassan Marine’s engineers are specifically trained in diagnosing faults caused by these conditions — not generic HVAC technicians, but specialists who understand marine-grade systems and the pressure of port windows.
