Dubai summers. Dubai can reach a scorching 45° Celsius in summer. The humidity on top can feel like a trapping sauna. One step outside really makes one appreciate air conditioning as a life-saving necessity. Your AC is not a luxury. Warm air blowing out or no air blowing out no matter the temperature setting on the thermostat is a cause for concern. It is vitally urgent to get it repaired as soon as possible. The positive news is that the majority of your air conditioning problems can be traced back to a few specific issues. Some of these problems can be resolved on your own within just a few minutes; others will need a technician to take a look. It can be helpful to understand what the causes of the problems are and the solutions that correlate. The Most Likely Causes When Your AC Stops Cooling 1. Dirty Air Filter This is the most common cause for low AC cooling in Dubai, and what’s even better is that it is completely avoidable! ACs in Dubai have a tough job throughout the year because of the fine sand, dust, and construction debris that are present in the air. Your AC filter traps that debris, but not for long. After a while, the filter becomes so clogged that it can’t trap debris anymore and let air pass through. Once a filter becomes blocked, the airflow is reduced significantly. As a result, the evaporator coil of your AC isn't able to absorb the heat from the room efficiently. The system then has to work harder just to move the air. You will notice a weak airflow coming from the vents and a sudden and considerable increase in your electricity bill. Quick Fix: Remove the AC filter and hold it to a light source. If it's opaque, it needs to be cleaned or replaced. Generally, split AC filters can be cleaned with water and dried. This should be done every 2 to 3 weeks while staying in Dubai during the summer. 2. Low Refrigerant (Gas Leak) Refrigerant (AC gas) absorbs and carries outside the heat from your indoor air. Any refrigerant gas leak means your AC will not be able to cool the indoor space. A refrigerant leak can be suspected if: • The air coming from the AC is not sufficiently cool, and the room is not cooled at all • There are hissing or bubbling sounds coming from the indoor or outdoor AC unit • There is frost or ice on the evaporator coil or copper tubing
the room to the desired temperature Refrigerant gas can only be handled by a certified technician, and if there is a refrigerant leak, then the gas will only be a temporary solution. 3. Dirty or Blocked Condenser Unit The condenser is the outdoor unit of a split AC system and releases the heat that was transferred to the outside air. Dubai's outdoor AC units have to work in extreme dry heat and need to deal with dust and sand. Blocked or dirty condenser coils mean heat cannot be released. The inability to disperse heat causes systems to operate at elevated temperatures. As internal heat causes the refrigerant lines to escalate in pressure, the system's ability to cool is compromised. In this scenario, the unit will likely run the risk of overheating and will ultimately shut down. What can you do? It is wise to keep the outdoor units of your system clear and unblocked. Proper airflow and coil cleanliness is not a DIY. You should call a professional to service your system and clean the coils with proper cleaning solution. 4. Thermostat Issues Before assuming the worst, try checking the thermostat. This one, we get some settings that do get changed. We blame the kids. We blame the digital thermostat updates. Make sure that: • You aren't stuck in Fan Only mode. • The setpoint isn't higher than the current room temperature. • The thermostat isn't in the sun. The AC unit not responding action could mean the thermostat sensor or control board could be damaged and a repair is needed. 5. Frozen Evaporator Coils
see ice, because yes, an AC unit is supposed to be cold. Believe it or not, ice actually indicates low refrigerant or airflow, and not that a system is working efficiently. Because the coil cools to the point of ice formation, airflow stops completely, and the unit begins to blow warm and moist air. If you think your coils are freezing: • Use the AC in Fan Mode or turn it off. • It takes 2-4 hours for the ice to melt on its own. • Inspect the air filter and clean it if needed. • Call a technician if the coils freeze again. The frozen coils will ruin the compressor in the AC. 6. Issues with the Compressor The refrigerant needs to be pressurized by the functioning compressor for the cooling cycle to be completed. The AC will provide almost no cool air if the compressor has begun to fail. As a rule of thumb, compressor problems are more often the result of systems that are 8-10 years+, have multiple summers of service in Dubai, or have experienced excessive refrigerant overcharging and/or oil selling. Some of the common/complementary symptoms of a compressor failing include: • Noisy grinding or clanking sounds from the outdoor unit • Frequent tripping of the circuit breaker • AC runs, but the air is not appreciably cooler • The outdoor fan runs and the compressor remains inactive. As a rule of thumb, compressor replacement is costly, and it may be more cost-effective to replace the entire AC system, particularly for a system that is older and more depreciated. A technician will be able to provide a better, more informed opinion on the system. 7. Leaks or Blockages in Ductwork (Central AC Systems) If you reside in an apartment or villa that has ducted central air conditioning, then ducting is an important factor. Ducts that are leaking or have inadequate insulation are prone to losing cooled air.
primarily due to poor ducting rather than a poorly functioning unit. With older duct systems, cracks can develop and blockages can be caused by pests or even work done on the building. Duct inspection is out of the scope of a visual inspection and requires precision instruments. If certain zones of the building do not cool, do not waste money on refrigerant or other repairs until the ductwork is evaluated. Some problems are more serious than others. Some problems are more serious than others. If the filter has been checked and the thermostat is in the correct position and the outdoor unit is making strange sounds or looks strange, call a technician. In the heat of Dubai, an AC that is “not cooling well” can worsen to a completely nonfunctioning unit in a few hours. During the summer, it is more difficult to call a technician during an emergency and more expensive. Dedicated routine servicing every six months keeps small problems from developing into large and expensive problems. At the hottest time of the day, your AC is working against the highest outdoor temperatures. If the system is in a marginal state (such as low refrigerant or dirty coils) then the system may work adequately at night, but will struggle when the temperatures increase during the day. Q: When is the best time to service an AC in Dubai? It is best to service your AC twice each year in Dubai. The first service should be done at the beginning of summer, around April or May. The second service should take place during the middle of summer or after. Because of the heavy amount of dust in Dubai and the high temperatures, the AC should be serviced more often than one time a year. Q: Should I be refilling the refrigerant in my AC? Absolutely not. Refrigerants should only be handled by certified professionals. Refrigerants should not be added to a system without first identifying the leak and conducting a proper leak test. Otherwise, the lost refrigerant will be a waste of money and will not solve the underlying issue.
cooling? This combination of symptoms seems to indicate a problem with the cooling system or the fan motor. To prevent any additional damage to the system, turn it off immediately. Q: Why does my AC run constantly all summer? It is common for an AC unit to run constantly all day and all night when the outside air is at its highest temperatures. It is common for an AC unit to not reach the target temperature at the hottest air temperatures of the year. However, if the AC unit runs constantly, that may indicate an undersized system, an improperly serviced system, or a system fault. Q: Why does my AC emit a musty smell when it runs? That odor is likely of mildew or mold that may be on the evaporator or in the drain pan. It is likely a dirty drain and a coil issue that may be serviced. Q: Is it possible for an electrical issue to be why my AC is not cooling? Yes, this is a possible. Capacitor failure, bad wiring, or a trip of the circuit may result in no cooling and may prevent the compressor and fan from functioning. An AC unit can seem to be working and running while it may not be cooling. Every in-depth AC unit troubleshooting must also include an electrical test. Q: How long should an AC unit last in Dubai? An AC unit can reasonably last about 10 to 15 years with regular servicing, but components can start failing after about 5 to 7 years without servicing. The conditions in Dubai can cause an AC unit to age rapidly. Get Help If your AC still isn't cooling after troubleshooting, you need professional help, as staying in Dubai's heat is not an option.
