AC Repair & Troubleshooting
Nine times out of ten, it’s one of three things: a dirty filter choking the airflow, a refrigerant leak dropping the gas level, or a coil so caked in dust it can’t transfer heat anymore. We check all three on the first visit, so you get an answer, not a guess.
A grinding or squealing sound usually means a fan motor is on its way out. Banging or rattling means something’s come loose inside the unit. Neither gets better on its own, so it’s worth a look before the part fails completely.
Almost always a blocked condensate drain line. Dust builds up inside that drain over months, and once it’s clogged, the water backs up and finds the nearest exit, usually your ceiling or wall. A drain flush clears it in minutes.
The usual suspects are low refrigerant, a struggling compressor, or airflow blocked by a dirty filter or coil. We run a full diagnostic first so you know exactly which one it is before we quote anything.
Yes, in almost every case. We respond within 30 minutes of your call and arrive within a 2 hour window, so same-day repair is the norm here, not the exception.
Every repair comes with a 30 day workmanship warranty. If the same issue comes back within that window, we return and fix it at no extra cost.
If it’s the exact same fault within our 30 day warranty period, we come back and fix it free of charge. If something new and unrelated comes up, we’ll diagnose that separately and let you know what it’ll cost before we start.
This usually points to low refrigerant or a capacitor that’s struggling once the system’s been running for hours straight. A proper diagnostic will tell you exactly which one it is, rather than guessing and hoping.
Under Dubai’s tenancy law, landlords are responsible for major repairs, including AC system failures like a broken compressor, since it affects the property’s basic habitability. Tenants are typically only responsible for minor, routine upkeep, like filter cleaning. Most tenancy contracts also set a specific cost threshold for what counts as minor, so it’s worth checking yours for the exact figure.
If your unit is past 10 years old and you’re calling us out repeatedly, replacement usually works out cheaper over time. If it’s younger and this is a one-off fault, repair almost always makes more sense. We’ll tell you honestly which situation you’re in, not just push whichever costs more.
AC Maintenance & Service Frequency
We recommend every 3 months. Dubai’s heat and dust put far more strain on a system than milder climates do, and quarterly AC maintenance catches problems long before they turn into breakdowns. If you’re in a particularly dusty area or near construction, that schedule matters even more.
Filter cleaning or replacement, a coil check, a refrigerant level check, and an inspection of the compressor, fan, and other key components. You’ll also get a written report with before and after photos, so you know exactly what was done.
Yes, and skipping it can actually void that warranty. Most manufacturer warranties require documented, regular servicing. A neglected unit voids the warranty faster than an old one ever could.
Around 1 to 2 hours per split unit, longer for central or ducted systems. We’ll give you a more specific estimate based on your setup when you book.
Landlords are generally responsible for major AC repairs, since a broken system affects the property’s habitability. Tenants typically handle minor, routine upkeep, like filter cleaning. Your tenancy contract usually spells out the exact threshold, so it’s worth checking that first.
Check and clean the filter monthly, keep the outdoor condenser unit clear of dust and debris, and pay attention to any change in noise, smell, or cooling performance. Leave anything involving refrigerant or internal components to a professional.
Yes, meaningfully. A dirty, neglected system can use up to 20 to 30% more electricity than a well-maintained one, since it has to work harder to produce the same cooling. Quarterly servicing is one of the few home maintenance habits that pays for itself.
A well-maintained system typically lasts 12 to 15 years. A neglected one, given Dubai’s climate, can fail in half that time.
AC Installation & Replacement
It comes down to your room’s square footage, ceiling height, sun exposure, and how many people typically use the space. As a rough guide, 1 ton suits up to around 12 to 14 square metres, but we do a proper load calculation on-site rather than guessing from a chart.
Daikin, Mitsubishi, and Carrier consistently hold up best against Dubai’s heat and dust, though O’General and LG are solid mid-range choices too. The brand matters less than correct sizing and installation, honestly, but if you’re choosing between two options, we’re happy to walk you through the tradeoffs
Around 4 to 6 hours for a standard split unit, longer for ducted or multi-zone systems. Rushed installation is one of the most common causes of early breakdowns, so we’d rather take the time to do it properly than finish fast.
In most apartment buildings, yes, especially if the outdoor unit placement or any exterior work is involved. Villas usually don’t need this, but it depends on your community’s rules. We can help you figure out what’s required before we start.
Standard installation covers the unit, refrigerant lines, drain pipe, and basic electrical connection, typically up to a 5 metre line run. Longer runs, ductwork for a central system, or major electrical work are usually quoted separately, since they vary so much from property to property.
Almost always, yes. Inverter units adjust their compressor speed instead of switching fully on and off, which means steadier cooling and meaningfully lower electricity use over a Dubai summer. The higher upfront cost typically pays for itself within a few years through lower DEWA bills.
Yes, where they’re required. Most straightforward split unit installations don’t need special permits, but larger jobs or central system work sometimes do, and we handle that paperwork as part of the installation service rather than leaving it to you.
Yes — mould is a very common problem in Dubai’s HVAC systems. The combination of cold air inside the ducts, warmth outside, and dust creates ideal conditions for mould growth. Mould inside ducts causes musty smells, allergic reactions, and can be a serious health hazard for children and people with respiratory conditions. Our duct sanitization service uses Dubai Municipality approved antimicrobial products that kill and prevent mould growth.
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.
Air Duct Cleaning
Once a year is the general baseline. But if something feels off before that, don’t wait. Dubai’s dust and humidity mean ducts here get dirty faster than in most climates.
A musty smell when the AC turns on, visible dust or dark buildup around vents, weaker cooling than usual, or family members developing allergy symptoms that ease up once they leave the house. Any one of these is worth a look.
A full inspection, industrial vacuuming to remove dust and debris, sanitization with an approved antimicrobial solution, and an airflow test at the end to confirm everything’s working. For a typical home, the whole process takes a few hours.
It depends on your property size and how many units you have. Check our pricing page for exact rates, or send us your details and we’ll give you a straight number before any work begins.
Ask for before and after photos, and check that the technician actually removed and inspected the vent covers rather than just vacuuming what’s visible from outside. A proper job covers the drain line and coil too, not just the ductwork itself.
No, the system needs to be switched off for both safety and a proper clean. It’s back up and running again once we’re done, usually the same day.
AC cleaning focuses on the unit itself, the filters, coils, and internal components. Duct cleaning goes further, into the actual channels that carry air through your home. Your AC could be spotless and the air still be dirty if the ducts have never been touched.
Yes, and faster than most people expect. Given the right conditions, moisture sitting in a duct can grow mould in as little as 48 hours. Dubai’s humidity makes this a genuine, ongoing risk, not a rare edge case.
Yes, on every job. You’ll also get a written report and our 7-day sanitization guarantee, so you have proof of the work and peace of mind if anything feels off afterward.
Pricing & Costs
It depends entirely on what’s actually wrong. A capacitor replacement costs a fraction of a compressor swap. We diagnose first and give you a written quote before any work starts, so you know the exact number before you commit to anything.
This varies by system type and property size, a split unit apartment costs less to service than a multi-zone villa with ducted AC. Send us your details and we’ll give you an exact number.
It depends on your property size, how many units you have, and how long it’s been since the ducts were last cleaned. Heavily contaminated systems take longer to clean properly. Full rates are on our pricing page if you want to see everything in one place.
We charge a diagnostic fee for the initial visit, but it’s waived if you go ahead with the repair. You’ll never pay to find out what’s wrong and then pay again to fix it.
All prices shown are exclusive of VAT. 5% VAT is added to the final invoice for every service, residential and commercial alike.
A few things drive this: the property type (a villa’s ducted system takes longer to service than an apartment split unit), the system’s age and condition, and how long it’s been since the last service. An older unit that’s never been properly maintained often needs more attention during the same standard visit than a well-kept one.
Annual Maintenance Contracts (AMC)
An AMC is a yearly contract that covers scheduled AC servicing plus priority response if something breaks between visits. You don’t strictly need one, pay-per-visit works fine for a newer system used lightly. But if you’ve got multiple units or a system that’s had issues before, an AMC usually works out cheaper and far less stressful than booking each visit separately.
Scheduled maintenance visits, priority emergency response, and a written report after every visit. The exact number of visits and level of coverage depends on which tier you choose, Essential, Premium, or Elite for residential properties.
It depends on your property size, number of units, and which tier you pick. Send us a few details and we’ll give you an exact quote rather than a rough range that may not apply to your situation.
Yes, that’s a core part of what an AMC is for. You get priority response for breakdowns, not just the scheduled visits themselves.
Yes, with 30 days written notice. You’ll get a pro-rata refund for any unused visits, minus the value of any emergency callouts you’ve already used at the AMC-preferential rate.
Yes. Commercial AMCs run on Basic, Standard, or Premium tiers, built around higher-usage systems and business continuity needs rather than a typical home setup.
Because they run on different schedules. AMC visits are quarterly, but duct and coil cleaning are only needed roughly every 18 to 24 months for most homes. Bundling something you need once every couple of years into every visit would just push the price up for no real benefit. It’s usually offered as an add-on instead.
Yes. A studio apartment and a five-bedroom villa don’t need the same coverage, and pricing and visit frequency adjust accordingly.
Gas Refilling & Refrigerant
The clearest signs are weak cooling despite the thermostat being set correctly, ice forming on the indoor coil, a hissing sound near the unit, or a noticeable jump in your DEWA bill without any change in usage. A proper diagnostic confirms it rather than guessing from symptoms alone.
No, and if you find yourself doing this every year, that’s actually a warning sign. Refrigerant runs in a sealed loop and shouldn’t deplete under normal conditions. A unit that keeps losing gas has a leak somewhere, and refilling without fixing that leak just means paying for the same problem again in a few months.
It depends on your refrigerant type, unit size, and whether a leak needs repairing first. Refilling without checking for a leak first is a false economy, since you’ll likely be back paying for the same service again soon.
Check the nameplate on your outdoor unit, it lists the exact refrigerant type. Most modern systems run on R410A or R32, while older units, typically installed before 2010, often still use R22.
Yes, significantly. R22 and R410A aren’t interchangeable, they run at different pressures and require different compressor oils. Using the wrong one can damage the compressor and will almost certainly void your warranty. A technician always checks the nameplate before touching the gas, never guesses.
Brands & Compatibility
All the major ones you’ll find here, Daikin, O’General, Mitsubishi, LG, Samsung, Carrier, and Gree included. If you’re not sure whether we cover yours, just ask, chances are we do.
Yes, more than most people expect. Premium brands like Daikin and Carrier build inverter boards specifically tuned for high-ambient heat above 45°C, while some budget brands’ boards are tuned for milder climates and can throttle or shut down under Dubai’s peak summer load. Compressor lifespan also varies significantly, premium brands often last 10 to 15 years, budget brands closer to 5 to 8.
Yes, switching brands on replacement is completely normal and doesn’t cause any compatibility issues. We’ll walk you through the tradeoffs so you pick something that actually suits your space and budget.
For the major brands we service regularly, yes. One thing worth knowing: parts for premium brands tend to stay available for 10+ years after a model is discontinued, while budget brand parts can become hard to find within just a few years. This matters more than people realize when a 6 or 7 year old unit needs a repair.
They’re both strong choices, just for slightly different priorities. Daikin tends to run quieter with lower long-term running costs, while O’General is known for particularly powerful raw cooling performance in extreme heat. Either holds up well here. The bigger factor is usually correct sizing and proper installation, not the brand badge.
Booking & Service Process
The fastest way is WhatsApp or a quick call. Tell us what’s going on and where you’re located, and Dubai Cooling Expert will get a technician scheduled the same day.
We respond within 30 minutes of your call and arrive within a 2 hour window. Same-day service is the norm here, not something you need to specifically request.
Just make sure someone’s home to provide access, and clear any obstructions around the indoor and outdoor units if you can. Everything else, we bring.
Yes, English and Arabic as standard, and many of our technicians also speak Hindi or Urdu, so you can explain the issue in whichever language is easiest.
For AMC customers, we try to keep the same technician assigned to your property whenever possible, since they already know your system’s history. For one-off bookings, whoever’s available and nearest gets sent, still fully briefed on your job before they arrive.
Chiller & Commercial Systems
A chiller cools water instead of air directly, then circulates that chilled water through a building to cool multiple zones at once, common in larger commercial buildings, hotels, and multi-unit residential towers. Yes, we handle both air-cooled and water-cooled chiller systems.
Monthly checks are standard for higher-occupancy commercial spaces, with a deeper quarterly service and a full annual inspection layered on top. Restaurants and hospitality venues often need it even more often, given the grease and moisture load they deal with daily.
Yes, we handle commercial duct cleaning at scale, offices, retail units, and larger buildings alike, scheduled around your operating hours so it doesn’t disrupt business.
Coil and tube cleaning, electrical and control checks, a refrigerant assessment, leak detection, lubrication, and calibration, finished with a performance log recording key temperature readings. Water-cooled systems also get water quality and flow checks that air-cooled units don’t need.
Yes, fully licensed and insured for commercial work across Dubai.
