Frequently Asked Questions

Typical residential AC repair pricing in Qatar starts at QAR 150 for a diagnostic visit. Most repairs land between QAR 200 and QAR 900 depending on the part. Capacitor replacement is around QAR 180–250, contactor or PCB QAR 350–600, gas refill QAR 250–500 depending on refrigerant type, and compressor replacement QAR 1,500–3,500. We always provide a written flat-rate quote before any work begins.

Warm air from an AC usually means one of five issues: low refrigerant from a leak, a frozen evaporator coil, a faulty compressor or capacitor, blocked condenser coils, or incorrect thermostat settings. In Qatar's heat, low refrigerant and dirty coils are by far the most common. A qualified technician can diagnose the exact cause in 20–30 minutes using manifold gauges and amp readings.

Water leakage almost always points to a blocked drain line, a tilted indoor unit, a damaged drain pan, or a frozen evaporator coil that thaws when the system stops. Algae growth in the drain line is extremely common in Qatar due to constant condensation. A professional drain flush with antimicrobial treatment usually resolves it in a single visit.

If your AC needs refrigerant, there is almost certainly a leak — sealed systems do not lose gas over time. A reputable technician will perform an electronic leak test and nitrogen pressure test, repair the leak (usually at a flare joint, weld or coil pinhole), then evacuate and recharge with the correct refrigerant. Topping up gas without fixing the leak is a short-term waste of money.

For a typical 25 square metre bedroom in Qatar you generally need a 1.5 ton (18,000 BTU) split AC. Higher ceilings, west-facing windows or rooms above 28 sqm move you to 2 ton (24,000 BTU). Under-sizing causes the compressor to run continuously and never reach set temperature; over-sizing causes short-cycling and high humidity. A professional load calculation is free with any quote from us.

Yes — most landlords in Qatar allow tenant-installed split ACs, but it is essential to get written permission first and document the wall condition before drilling. We provide a tidy installation with proper drain routing, insulated copper, certified brackets and signed work-completion forms that protect your deposit when you eventually move out.

A standard split AC installation takes 2–4 hours including bracket mounting, copper piping, drain line, electrical wiring, vacuum pull-down and commissioning. Long pipe runs, complex routing or villa multi-unit installs can extend this to a full day. We always confirm the timeline at the survey stage.

Newer units (2016+) typically use R32 or R410A. Mid-2000s to 2015 units commonly use R22, which is being phased out globally. Older units may use R407C. The refrigerant type is printed on the outdoor unit nameplate. We carry all four refrigerants on our service vans, so you never wait for parts.

Yes, R22 is still available in Qatar through licensed wholesalers, but supply is tightening every year and prices continue to rise. If your unit is older than 10 years and uses R22, it is often more economical to replace it with a modern R32 unit that uses 30–40% less electricity.

A complete AC maintenance visit includes filter wash, indoor coil cleaning, drain line flush, outdoor coil rinse, fan motor lubrication, electrical safety check (capacitor, contactor, terminals), refrigerant pressure check, supply-air temperature measurement, and a written condition report with recommendations. The whole visit takes 60–90 minutes per unit.

Yes — a manufacturer warranty covers part failure but does not cover routine maintenance like filter cleaning, coil washing or drain flushing. Without regular maintenance, dust build-up causes overheating that voids many warranties. An AMC ensures your warranty stays valid while keeping the system running efficiently.

Uneven cooling is usually caused by blocked or partially closed registers, leaky ducts, an undersized return-air path, or poor insulation in the warmer room. In multi-split or VRF systems it can also indicate refrigerant distribution issues. A quick airflow and pressure test identifies the exact cause.

An AC freezes when airflow across the evaporator coil drops below the design point — typically due to a clogged filter, a dirty coil, a failing blower motor, or low refrigerant. Continuing to run a frozen AC will damage the compressor. Switch off, let it thaw fully (2–4 hours), and call a technician.

Yes. A heavily clogged filter starves the evaporator coil of warm return air, causing it to freeze. When the unit cycles off, the ice melts faster than the drain pan can handle and overflows. Filter cleaning every 4–6 weeks in Qatar prevents this.

Loud outdoor units usually indicate loose mounting bolts, a failing fan motor bearing, a bent fan blade, debris inside the cabinet, or a struggling compressor. A grinding metallic noise needs immediate attention as it usually means bearing failure that can cascade into compressor damage.

With regular maintenance, a residential compressor in Qatar lasts 8–12 years. Without maintenance, lifespan drops to 4–6 years due to dust-related overheating. Twice-yearly coil cleaning, correct refrigerant charge and stable voltage are the three biggest factors in compressor longevity.

If the unit is under 7 years old and the rest of the system is in good condition, replacing the compressor is cost-effective. If the unit is 10+ years old, uses R22, or has shown multiple faults, full replacement with a modern inverter unit usually pays back in 2–3 years through electricity savings.

A 1.5 ton non-inverter split AC running 10 hours per day in Qatar summer consumes roughly 600–750 kWh per month, costing QAR 45–60 on KAHRAMAA tariffs. A modern inverter unit of the same capacity drops this to 350–450 kWh — a saving of about QAR 25–35 per unit per month.

Yes — inverter compressors modulate output instead of cycling on and off, typically saving 30–40% on cooling electricity. In Qatar where AC accounts for 60–70% of summer KAHRAMAA bills, the saving is significant. A QAR 3,500 inverter upgrade often pays back in 18–24 months.

Most HVAC engineers recommend 24°C as the sweet spot for comfort and efficiency in Qatar. Every degree below 24°C increases consumption by roughly 6%. Set 26°C overnight when bodies cool naturally. Using a programmable or smart thermostat to ramp up before you wake produces the biggest savings.

Most remote failures in Qatar are heat-damaged batteries, a dirty IR sensor on the indoor unit, or moisture inside the remote from condensation. Replace batteries first, wipe the sensor clean, and try again. Persistent issues usually mean the indoor unit's receiver board has failed and needs replacement.

Every 4–6 weeks during the cooling season in Qatar, and every 8–10 weeks in cooler months. Homes near construction sites, the Corniche or desert edges should clean weekly. Filters are washed with warm water and mild detergent, dried completely, and reinstalled — no replacement needed for most washable mesh filters.

Significantly. A full coil clean, drain disinfection and HEPA filter upgrade can cut airborne dust, mould spores and bacteria by 70–90%. Many of our customers with asthma or allergies notice symptom improvement within a week of a deep-clean service.

Musty AC smells almost always indicate bacterial or mould growth inside the evaporator coil, drain pan, or drain line. A chemical coil wash with EPA-approved sanitizer plus drain pan disinfection eliminates the smell at source. Filter replacement alone rarely fixes it.

Yes — our emergency line is staffed every night, weekend and public holiday. Average response inside Doha is under 90 minutes. Surcharges apply between 10 PM and 6 AM and on Eid days, fully disclosed when you book.

Total cooling failure with infants, elderly residents, or medical equipment in the home; water leakage damaging ceilings or electronics; burning smells or sparks from the unit; and commercial cooling loss affecting food storage or guest comfort are all genuine emergencies. We prioritise these calls.

Yes — we service kitchen exhaust hoods, make-up air units, walk-in coolers, prep-area split AC and rooftop packaged units for restaurants across Qatar. We can also issue NFPA-compliant cleaning certificates required by Civil Defence.

Yes. Our senior engineers are factory-trained on Daikin VRV, LG Multi V, Samsung DVM S, Mitsubishi City Multi, Carrier XCT7 and Toshiba SHRM systems. We carry diagnostic software, original PCBs and refrigerant gauges for all major brands.

Yes — we service most large compounds in Qatar including The Pearl, Education City, Aspire Zone, Barwa City, Ezdan and Lusail Marina compounds. Compound-wide AMC pricing is available with significant per-unit discounts.

Our 90-day workmanship warranty covers any failure of the original repair or any fault caused by our work. Spare parts are covered separately under the manufacturer warranty (typically 12 months on labour, 5 years on compressor). Faults caused by power surge, water damage or improper use are excluded.

Yes — when you sign an Annual Maintenance Contract, the workmanship warranty extends for the full duration of the AMC and the manufacturer warranty registration is managed on your behalf.

The diagnostic fee covers the technician's time, fuel and equipment for a complete fault-finding visit. It is fully waived if you proceed with the repair. We charge it transparently rather than padding repair invoices to disguise the cost.

Yes. Villas with 4+ units, AMC clients and compound contracts receive significant per-unit discounts on maintenance, gas refill and parts. Ask for a custom quote.

Qatar's heat, humidity and salt-laden coastal air reduce typical AC lifespan by 30–40% compared to manufacturer ratings. Aluminium fin corrosion, copper pitting and dust-clogged condensers are the primary causes. Twice-yearly maintenance with coil rinsing and corrosion protection coatings extends life significantly.

Yes — coastal areas like West Bay, The Pearl, Lusail Marina, Wakrah Beach and Al Khor Corniche experience accelerated corrosion. We apply a marine-grade epoxy coating to outdoor coils on request, which can triple coil lifespan in salt-exposed locations.

Three actions deliver the biggest savings in Qatar: set thermostats to 24°C minimum, replace non-inverter units with inverters, and service units twice yearly. Together these reduce cooling-related KAHRAMAA bills by 35–50%. Adding ceiling fans, blackout curtains and door seals adds another 10–15%.

Yes — smart Wi-Fi controllers from Sensibo, Cielo, Tado and Ambi Climate work with virtually any split AC in Qatar and add scheduling, geofencing and remote control. Average payback through energy savings is 6–9 months.

Wash filters every 4–6 weeks, keep furniture and curtains clear of the indoor unit, rinse the outdoor condenser with low-pressure water monthly to clear dust, set thermostat to 24°C, and never block the supply or return grilles. These five habits prevent 80% of avoidable AC failures.

For short absences (under 4 hours) leave the AC running at 26–27°C. Starting from a hot house actually consumes more energy than maintaining a moderate temperature. For long absences (full day, holiday), switch off entirely and rely on insulation.

As a rule, if the repair costs more than 40% of a new equivalent unit and your AC is over 8 years old, replacement is more cost-effective. Modern inverter units recover the price difference in 18–24 months through electricity savings. Our engineers give honest advice — we will tell you when replacement makes more sense than repair.

Filter cleaning, drain flushing and basic outdoor coil rinsing are safe DIY tasks. Anything involving refrigerant, electrical wiring, capacitors or compressors requires a licensed technician — refrigerant handling is regulated in Qatar and capacitors store lethal voltage even when the unit is off.

We use certified powder-coated steel brackets rated for 200+ kg, anchored into structural concrete with M10 expansion bolts. We carry a structural risk certificate and full third-party liability insurance for installation work.

Yes — we are authorised resellers for LG, Samsung, Daikin, O General, Gree, Carrier and Midea with brand pricing that matches or beats most local retailers. Bundled supply + install includes free first-year maintenance.

Chemical AC cleaning is a deep-clean process where the indoor coil, blower wheel and drain pan are treated with EPA-approved coil cleaner and antimicrobial sanitizer, then thoroughly rinsed. It removes bio-film, mould and embedded dust that water-only cleaning leaves behind. Recommended once per year.

Regular cleaning rinses filters and surfaces. Our deep-clean dismantles the indoor unit (blower wheel, coil cover), washes each part separately with coil cleaner, sanitizes the drain pan, flushes the drain line and reassembles with new gaskets if needed. Results last 6–12 months instead of 2–3 weeks.

Yes — for ducted systems older than 18 months, professional duct cleaning removes accumulated dust, bacteria and mould that recirculate through every room. Customers commonly report less sneezing, less dust settlement on furniture and improved cooling within 24 hours. Recommended every 18–24 months in Qatar.

We use rotary brush agitation with HEPA-filtered negative-pressure vacuum, followed by antimicrobial fogging. The process is dust-free for the home, takes 4–8 hours depending on duct length, and includes before-and-after photo evidence.

For Qatar's harsh climate, the strongest performers are O General, Daikin, LG and Samsung — all with proven coil durability and good local parts support. Mid-range options include Gree, Midea and TCL with excellent value but slightly shorter life expectancy. Avoid no-name brands as parts availability is poor.

O General has built a strong reputation in Qatar for cooling capacity in extreme heat and robust coil construction. They are excellent units but priced 20–30% above equivalent LG or Samsung models. Modern LG and Daikin inverter units now match or exceed O General performance at lower cost.

For absences longer than a week, switch off the AC at the breaker and leave windows slightly open or use a dehumidifier to prevent mould growth. Before leaving, run the AC on fan-only mode for 30 minutes to dry the coil and drain pan. Coming back, run on fan for 10 minutes before switching to cooling.

Stagnant moisture in the indoor coil and drain pan grows mould and bacteria during long shutdowns, producing a musty smell when the unit restarts. A chemical clean and drain pan sanitation eliminates it and prevents recurrence with simple pre-departure routines.

One ton of cooling equals 12,000 BTU per hour — the heat needed to melt one ton of ice over 24 hours. A 1.5 ton AC delivers 18,000 BTU/hr, suitable for a typical 22–28 sqm Qatari bedroom. A 2 ton unit (24,000 BTU/hr) suits 30–40 sqm living rooms.

Slightly, but an oversized unit reaches the set temperature too quickly without dehumidifying the air properly, leaving the room cool but clammy. It also short-cycles, wearing out the compressor faster. Correct sizing produces better comfort and longer life than oversizing.

Yes — for split ACs, a universal Wi-Fi remote like Sensibo, Cielo or Tado lets you control any infrared AC from your phone with scheduling, geofencing and voice control via Alexa or Google. Installation takes 10 minutes.

Yes — most central and ducted systems in Qatar work with Nest, Ecobee or Honeywell Lyric smart thermostats. We supply and install them with full wiring verification and homeowner training. Typical install is 90 minutes.

Yes — modern ACs are designed for continuous operation and have multiple safety cut-outs. Use 25–26°C overnight for comfort and efficiency. Annual maintenance ensures the safety controls (high-pressure switch, overload, thermal fuse) are working correctly.

Rarely, but it can happen with overloaded circuits, failed capacitors or aged wiring inside the indoor unit. Annual electrical safety inspection, correct breaker sizing and avoiding extension cords eliminate the risk almost entirely.

R32 has roughly one-third the global warming potential of R410A and is the current industry preference for new installations. Both are equally safe for occupants when handled by trained technicians; R32 is mildly flammable and requires specific brazing procedures that our engineers are certified for.

Global supply restrictions on older refrigerants (R22 phase-out, R410A quotas) and increasing demand from the GCC have driven prices up 40–60% since 2020. We pass through wholesale pricing transparently and stock all common refrigerants on our vans.

WhatsApp +974 5591 9941 with your area, building name, AC brand and a photo of the unit and the error code (if any). This lets dispatch send the right technician with the correct parts on the first visit, often the same day.

Yes — use our contact page to send a request 24/7. WhatsApp is faster for urgent issues. Phone booking gives you a confirmed time slot within minutes.

Yes — we service every populated area including Doha, Lusail, Al Wakrah, Al Rayyan, Al Khor, Umm Salal, Mesaieed, Dukhan, Al Shahaniya, Al Daayen and surrounding compounds. Remote locations may have a longer arrival window.

A small travel supplement applies for Mesaieed, Dukhan, Ras Laffan and locations more than 60 km from Doha. The supplement is disclosed when you book — usually QAR 50–150 depending on distance.

Yes — every job ends with a printed or emailed invoice listing parts, labour, refrigerant used (if any), and the 90-day warranty terms. Corporate clients receive proper VAT invoices suitable for accounts.

Yes — we provide signed service reports with date, technician name, work performed and recommended actions. Many tenants in Qatar use these to claim against landlords for ongoing AC issues.

Yes. A dirty AC can circulate mould spores, dust mites and bacteria that trigger asthma, allergies and respiratory infections. Twice-yearly deep cleaning combined with HEPA filtration significantly reduces airborne contaminants and is especially important for households with children or elderly residents.

Yes — all our coil cleaners and sanitizers are EPA-approved, biodegradable and safe for re-occupancy within 30 minutes of application. We thoroughly rinse the coil after cleaning so no chemical residue remains in the airflow.

We use genuine OEM parts as standard. We will only offer aftermarket parts if you specifically request them for budget reasons and the part is from a reputable Tier-1 manufacturer. The choice is always clearly documented on the quote.

For LG, Samsung, Daikin, O General and Carrier we stock most common parts on the van or at our warehouse. Specialty boards or compressors for older units typically arrive within 24–72 hours from local distributors.

Yes — we hold third-party public liability insurance covering customer property and individuals up to QAR 1 million per incident. Insurance certificate available on request.

In the unlikely event of accidental damage, our liability insurance covers full repair or replacement. We carry the policy specifically to protect customers and document every site with photos before work begins.

Our team includes 30+ in-house technicians, 4 senior engineers, 2 chiller specialists and a 24/7 dispatch crew. We do not subcontract — every job is performed by a uniformed AC Repair Qatar employee.

AC Repair Qatar was established in 2010. Over 14 years we have completed more than 60,000 service calls across Qatar with a 4.9★ average rating across Google, Talabat and our internal feedback system.

Yes — we install and configure smart AC controllers (Sensibo, Cielo, Tado), smart thermostats (Nest, Ecobee, Honeywell) and integrate with Apple HomeKit, Google Home, Amazon Alexa and Samsung SmartThings.

The drain water from your AC is condensation pulled out of the indoor air. It must drain to an external location — never into a closed cavity or a building's gray water system. Many older installations in Qatar drain incorrectly; our installation team always provides a proper sloped drain to an approved outlet.

Outdoor condensers need at least 60 cm clearance on every side, shade where possible, and protection from direct salt spray. They should sit on vibration-isolating pads and be slightly elevated to allow drainage. Bad placement reduces efficiency by 20–30% and shortens compressor life.

Run the fan-only mode for 15 minutes before switching off to dry the coil. Keep humidity below 60% indoors. Have the coil chemically cleaned annually. Replace the filter if it shows visible bio-growth. These steps together prevent virtually all AC-borne mould issues.

A hard-start kit is a capacitor add-on that helps an aging compressor start under load. It extends the life of struggling compressors by 6–18 months and is a budget-friendly stopgap when full compressor replacement is not yet feasible. We install them in 30 minutes with full diagnostic confirmation first.

A humming compressor that fails to start usually means a failed start capacitor, a seized rotor, locked-rotor amperage trip, or low incoming voltage. The fix is sequential: test and replace the capacitor first; if that fails, a hard-start kit; if that fails, compressor replacement.

KAHRAMAA voltage in Qatar is generally stable, but localised dips and surges during peak summer can damage capacitors and PCBs. A QAR 250–400 voltage stabiliser fitted to the AC circuit pays for itself the first time it prevents a board failure.

Yes — Gree is one of the most common brands in Qatar's rental market. We stock common Gree spares including capacitors, PCBs, fan motors and remote receivers, and our engineers are factory-trained on the Gree GMV5 VRF range.

Yes, window units remain legal and common in older buildings. They are less efficient than splits but cheaper to install and maintain. We service all major window unit brands and can also professionally remove them when you upgrade to a split system.

Yes — we offer window-to-split conversion including patching the old window cut-out, removing the wooden frame, drilling for the new copper line, and installing a modern inverter split. Typical project takes one day and costs QAR 1,800–3,500 depending on AC brand and capacity.

A cassette AC is a ceiling-mounted unit that sits flush in the false ceiling and blows air in four directions. They are common in offices, restaurants and showrooms. We service all cassette types including 1-way, 2-way and 4-way blow.

Slightly — cassette units require false ceiling access and specialised cleaning tools to dismantle the four-way grille. But the working principle is the same as a split, and our team handles cassette service daily across Qatar offices.

Ducted systems can be very efficient when properly designed, with one outdoor unit serving multiple zones via insulated ducting. Poorly designed or leaky ducted systems can lose 20–30% of cooling to roof spaces. Annual duct integrity inspection is critical.

Not necessarily — well-maintained ducted systems are quieter, more discreet and often more efficient than equivalent splits. We recommend keeping ducted if your system is under 12 years old and well-installed. Switch only if duct condition is poor or major component failure occurs.

An inverter AC modulates compressor speed instead of running flat-out and switching off. The result is steadier temperatures, quieter operation, and 30–40% lower electricity consumption. Virtually every modern AC in Qatar is now an inverter — non-inverter units are increasingly only used as budget rentals.

Yes — modern inverter ACs from LG, Daikin, Samsung and O General are tested for ambient temperatures up to 52°C and perform reliably across the Qatari summer. The myth that inverters struggle in extreme heat dates from early 2000s technology and is no longer accurate.

A modern split indoor unit on low fan speed is typically 22–28 dB — quieter than a whisper. Outdoor units are 48–58 dB. Sudden increases in noise indicate fan bearing wear, loose mountings, or refrigerant flow issues, all of which we can diagnose in a single visit.

Excessive vibration usually means loose wall mounting bolts, a worn fan motor bearing, an unbalanced fan blade, or refrigerant slugging due to overcharge. Vibration accelerates wear across the whole system and should be diagnosed promptly.

No — we do not resell used units. Our quality standards require traceability, full manufacturer warranty and verified performance, which used units cannot guarantee. We do offer trade-in credit toward new units when replacing your old AC.

Yes — we partner with a Qatari recycling firm that responsibly recovers refrigerant, copper, aluminium and plastics from end-of-life AC units. We can collect and recycle your old unit free of charge with any new installation.

14 years in business, 60,000+ completed jobs, 2,400+ verified reviews, MEP-licensed, KAHRAMAA-aware, Civil Defence registered, in-house technicians (no subcontractors), full insurance cover, transparent flat-rate pricing and 90-day workmanship warranty in writing. We earn trust on every job, every day.
