AC Repair & Troubleshooting
The most common reasons are: dirty air filters blocking airflow, low refrigerant gas, a dirty or frozen evaporator coil, or a faulty thermostat. In some cases, the compressor may be failing. A quick diagnostic visit from our team will identify the exact cause within 30 minutes. We do not charge for the diagnostic fee if you proceed with the repair. See our AC repair service โ
Different sounds point to different problems. A rattling or vibrating sound usually means a loose panel or debris in the unit. A hissing sound often indicates a refrigerant leak. A grinding or squealing noise points to a failing motor or bearing. A clicking sound at startup is often a relay or electrical issue. Do not ignore unusual AC noises โ call us for a same-day inspection.
Water leakage is almost always caused by a blocked drain line or a dirty air filter. When the filter is clogged, ice can form on the coil and then melt into a pool. A cracked or overflowing drain pan is also common. If water is dripping from your indoor unit, switch off the AC immediately to prevent ceiling or wall damage, and contact us for same-day repair.
This usually means your refrigerant (gas) level is low due to a leak, or your evaporator coil is completely blocked with ice or dirt. It can also be caused by a broken compressor. Our technician will perform a full pressure test and visual inspection to determine the exact cause before any repair is started.
Yes. We offer same-day AC repair across all Dubai areas. Call or WhatsApp us before 2:00 PM and in most cases a certified technician will arrive the same day. For urgent breakdowns, our emergency response line is available 24 hours, 7 days a week.
We provide a 90-day workmanship warranty on all labour and repairs. For parts, the warranty depends on the component โ most compressors and electrical parts come with a 6-month to 1-year manufacturer warranty. All warranty terms are given to you in writing before work begins.
If the same fault recurs within our 90-day warranty period, we will return and fix it at no additional charge. Our technicians diagnose the root cause before repairing โ not just the symptom โ which is why our repeat call rate is very low.
Yes. We repair all major AC brands available in Dubai including Daikin, O’General, Samsung, LG, Carrier, Mitsubishi Electric, Midea, Super General, Hitachi, Panasonic, Gree, Haier, Toshiba, York, Trane, TCL, and more.
In most Dubai apartments, the HVAC system is the tenant’s responsibility to maintain and service, unless your tenancy contract specifically states otherwise. Duct cleaning, filter cleaning, and AC servicing are usually your responsibility. Check your tenancy contract or speak to your building management. If in doubt, we can advise you directly after a quick call.
Generally, if your AC is under 7 years old, repair is the better value. If it is 7โ10 years old and the repair cost exceeds AED 800, it is worth comparing repair versus replacement โ especially since new inverter units can reduce your DEWA bill by 20โ30%. If your unit is over 10 years old and needs a major repair, replacement is usually the smarter long-term investment. Our technicians will give you an honest recommendation without pressure. See AC replacement guide โ
AC Maintenance & Service Frequency
In Dubai, we recommend servicing your AC every 3โ4 months. Because AC systems run almost continuously in Dubai’s extreme climate, dust and debris build up much faster than in cooler countries where servicing every 6โ12 months is standard. Our Annual Maintenance Contract (AMC) includes 3โ4 scheduled service visits per year, which is the most convenient and cost-effective option.
A standard AC service by Dubai Cooling Expert includes: cleaning and washing all filters, checking refrigerant pressure, inspecting and cleaning the evaporator coil, cleaning the drain line and drain pan, checking all electrical connections and capacitors, testing the thermostat accuracy, inspecting the blower fan, checking airflow from all vents, and a full performance test. You receive a written service report after every visit. See our maintenance service โ
Yes. Manufacturer warranties in the UAE typically require proof of regular professional maintenance to remain valid. Skipping maintenance can also void your warranty if a fault is found to be caused by neglect. In Dubai’s harsh climate, even a new AC can develop problems without regular servicing.
A standard service visit for a single AC unit takes 30โ45 minutes. For a villa with multiple AC units, allow 2โ4 hours. We will confirm the estimated time when you book so you can plan accordingly.
Yes, absolutely. Our technicians are trained professionals who come prepared with all equipment. You do not need to move furniture or vacate the property. The process is clean, quiet, and non-disruptive. Many of our customers simply carry on working from home while we service their AC.
Between services, you can wipe the outer casing with a dry cloth, make sure furniture or curtains are not blocking the airflow from vents, check that the thermostat is set correctly, and listen for any unusual sounds. Avoid removing or washing internal filters yourself unless you are confident โ incorrect reassembly can reduce cooling efficiency.
Yes, significantly. A dirty or poorly maintained AC works harder to reach the set temperature, consuming more electricity. Regular servicing and duct cleaning โ especially coil cleaning โ can reduce your AC energy consumption by 15โ25%. In Dubai’s summer months when your AC runs 18+ hours a day, this can translate to hundreds of AED in savings.
A well-maintained AC in Dubai typically lasts 12โ15 years. Without regular maintenance, this can drop to 7โ10 years. Dubai’s extreme temperatures and continuous usage put more strain on AC components than in most countries, which is why Dubai-specific maintenance frequency is higher than global standards.
Air Duct Cleaning
We recommend cleaning your air ducts every 12 months in Dubai. The combination of desert dust, sandstorms, high humidity, and year-round AC use causes ducts to accumulate contamination far faster than in other climates. If you have young children, elderly residents, allergy sufferers, or asthma patients at home, consider cleaning every 6โ9 months. See our residential duct cleaning โ
For a typical 1โ2 bedroom apartment (1 AC unit), expect AED 549โ799. For a 3โ4 bedroom villa with 3โ4 AC units, prices typically range from AED 1,499โ2,999. Commercial and large villa projects are quoted individually. Contact us for a free quote โ we will give you a clear price before any work begins with no hidden charges. See full pricing โ
Yes. Every duct cleaning job includes before-and-after photos of the internal duct condition, plus a written service report. This is your proof of work and serves as a maintenance record for your property files. No other major Dubai duct cleaning company does this as standard.
AC Installation & Replacement
AC capacity is measured in BTU (British Thermal Units) or tons. As a general guide for Dubai’s climate: a room up to 20 sqm needs 9,000โ12,000 BTU (1 ton); up to 30 sqm needs 12,000โ18,000 BTU (1.5 ton); up to 45 sqm needs 18,000โ24,000 BTU (2 ton). However, ceiling height, sun exposure, number of windows, and insulation all affect the correct size. Our team will calculate the exact requirement during a free pre-installation site visit. See AC installation โ
Pricing & Costs
AC repair pricing depends on the fault. A diagnostic visit costs AED 99 (waived if you proceed with the repair). Gas refilling (R410A) costs AED 249โ399 per unit. Compressor replacement costs AED 800โ3,000 depending on brand and size. Capacitor or PCB replacement costs AED 199โ499. Drain line clearing costs AED 150โ300. All prices are confirmed in writing before work begins. No hidden charges. See full repair pricing โ
Yes. We offer multi-unit discounts for properties with 3 or more AC units. AMC packages provide the best overall savings โ typically 20โ30% cheaper than booking individual service visits. Bundle packages available: Summer Ready Pack (AED 349), Clean Air Pack (AED 699), New Tenant Pack (AED 749), Villa Care Pack (AED 799). See all bundles โ
Annual Maintenance Contracts (AMC)
An AMC (Annual Maintenance Contract) is a yearly service agreement that includes a set number of scheduled AC service visits, priority emergency response, discounted repair rates, and regular system health checks. In Dubai’s extreme climate where AC runs almost year-round, an AMC is strongly recommended for all homeowners and businesses. It prevents expensive emergency breakdowns, extends the life of your AC, and gives you peace of mind. See residential AMC โ
Our Residential AMC includes: 2โ4 scheduled AC service visits per year (depending on tier), priority same-day emergency response, full written service reports after each visit, discounted rates on repairs and parts, and WhatsApp maintenance reminders. Our Commercial AMC includes: quarterly visits, 24/7 priority emergency line, detailed HVAC health reports, and customised coverage. See all AMC tiers โ
Yes. Our Commercial AMC covers offices, retail spaces, restaurants, hotels, warehouses, and other commercial properties. Tiers from Silver (AED 1,999/yr, 24hr SLA) to Gold (AED 3,999/yr, 8hr SLA) to Platinum and Enterprise (custom). All include compliance documentation. Se commercial AMC โ
Gas Refilling & Refrigerant
Gas refilling (R410A refrigerant) typically costs AED 249โ399 per split AC unit in Dubai, depending on how much refrigerant is needed. This includes the refrigerant charge and labour. If a leak is present, leak detection and repair adds AED 200โ400 depending on the location. We always quote the full cost before starting. See repair pricing โ
Most modern AC units in Dubai use R410A refrigerant. Older units (typically pre-2010) may use R22, which is being phased out globally due to environmental regulations. R22 is now harder to source and more expensive. If your older AC needs frequent gas refills and uses R22, it may be worth considering replacement with a modern R410A unit. See AC replacement โ

Chiller & Commercial Systems
A chiller system is a large central cooling system used in commercial buildings, hotels, hospitals, and some large villas. Unlike split AC units, chillers use chilled water to cool air across multiple zones or floors. Yes, we service chiller systems โ including preventive maintenance, leak detection, pump servicing, and full overhaul. See chiller maintenance โ
Commercial HVAC systems in Dubai require quarterly (every 3 months) preventive maintenance as a minimum. High-traffic buildings such as restaurants, hotels, hospitals, and offices may require monthly inspections. Our Commercial AMC is designed specifically for businesses that need reliable, scheduled HVAC coverage.
Yes. We provide commercial duct cleaning services for offices, retail units, restaurants, hotels, warehouses, hospitals, schools, and other commercial properties.
