Air Conditioner Not Lowering Temperature | Troubleshooting Tips

Centralized air conditioning systems are commonly placed in the homes in Dubai. The residents of Dubai bear the harshly hot weather with the help of their ACs. Therefore, it’s essential that you get some know-how of AC maintenance in Dubai.

Imagine your AC stops working in the middle of a hot day. Or you have come home after a long tiring day and you find that your air conditioner isn’t cooling the room. 

You probably are familiar with this situation. The irony is that it usually doesn’t happen in cold weather. Rather, it typically happens when you are sweating profusely in the month of June in Dubai.

There can be one of the multiple causes of your air conditioner running but not cooling your home. Keep reading as we will discuss them one by one.

The thermostat may be the culprit of Air Conditioner

Your thermostat settings should be set to cool. Check it first. If it’s set to cool, then check the temperature setting. Maybe one of your family members has changed it.

If the temperature is off, choose the <heat> option. Or turn on the constant fan, then choose the cooling option again. Wait for a couple of minutes once the system starts off. Then, check if the air flowing out from the registers is cold. If yes, the issue is resolved!

Otherwise, try the next troubleshooting tip which is discussed in the next section.

Check your air filter

A dirty air filter can be the cause of the issue. Most air conditioners in Dubai and elsewhere,  have an air filter placed in or near the internal air handler unit. 

The filter picks dust, grime, and other particles in the air as they get inside the air handler system. It ensures that all parts inside the unit stay cleaner. And functions more effectively. It also can aid in keeping the air in the house cleaner.

However, if the air filter becomes dirty, it may hinder airflow. It can decrease the cooling of your AC. If stays unattended, your system may shut down completely.

The solution

Find out the location of the unit’s air filter. Shut down the unit. Take out the filter and assess it. Clean it if needed. But, if it’s already clean and the problem is still there, you need to go deeper to identify the issue.

The condenser coil is clogged

Most centralized AC systems in Dubai contain an exterior condenser unit. The external part of the condenser system has a big outer coil. It covers most of the outer area of the unit circularly.

This coil features a tightly spaced series of sleek metal “fins”.

A blocked condenser coil can be the cause for an air conditioner running but not lowering temperatures.

The solution

The condenser fan withdraws energy out of your house. It works by sucking the air into the outer unit with the help of the condenser coil.

Sometimes, dust, grass, and debris in the air gather between the fins. It clogs the coil. 

A clogged coil can increase electricity bills and decrease cold air from the AC. it can even cause the system to completely collapse. Or the compressor can get damaged from overuse.

You can clean the coil by removing particles. Hoover the coil thoroughly with a brush attachment. Or wash it carefully with a hose. 

Is the problem still there even after cleaning the air filter? Then, it’s time to contact a home maintenance company in Dubai to help you.

Your Heat Pump Of Air Conditioner May Be Damaged

Some AC systems in Dubai have a heat pump as their outdoor unit. A heat pump is similar to an AC unit in appearance. But it has a couple of different parts inside it. These parts enable it to both heat and cool a house.

While cooling, it functions similar to an AC system’s condenser unit. It means that it may face the same problems. Dusty or blocked coil, refrigerant drips, frozen coil, compressor issues, etc.

Is your heat pump not cooling? Make sure the thermostat is correctly set, and check the air filter and the condenser coil for issues we have discussed above.

If your heat pump system is cleared out too, consult a company that deals with AC repair in Dubai. 

Frozen evaporator coil of Air Conditioner

Your centralized air conditioning system in Dubai contains an indoor component that is the evaporator coil.

Your indoor unit is either a furnace or a fan coil. If the furnace is your indoor unit, the evaporator coil is located in its cabinet outside the furnace.

While if the indoor unit is a fan coil (generally as a component of a heat pump), the evaporator coil is located inside the cabinet of the fan coil.

As hot air present inside the home flows through the evaporator coil, its humidity and heat energy are removed. And the air comes out cooler and more pleasant.

Your evaporator coil may be frozen if you notice these signs.

• Frost on the copper refrigerant tubing originating from the coil cabinet
• Improper cooling
• Increased energy consumption
• Extreme condensate drainage close to your indoor unit
• If the situation becomes extremely worse, you will see frost on external refrigerant tubing/the outdoor unit

A layman may find it hard to reach the evaporator coil. Therefore, it’s best to call a professional who masters air conditioner maintenance in Dubai if your AC has a frozen evaporator coil.

A refrigerant leak in Air Conditioner

Refrigerant is a chemical used in the cooling process. It passes through the AC’s outdoor and indoor coil. There, it changes its state from liquid to gas. And it presses out moisture and heat from the inside air and blows it outside.

Subject to its seriousness, a refrigerant leak can cause one of these:

• Your AC doesn’t give out cool air
• The AC may function for endless hours and still doesn’t properly cool your place
• Your compressor gets damaged or collapses
• Your AC system fully shuts down

If you want to check and resolve problems relating to the refrigerant levels in the air conditioning system, we recommend you take the services of a maintenance professional in Dubai.

Wrongly sized Air Conditioner system

Air conditioners in Dubai are sized based on the extent of cooling they can offer. It is measured in British Thermal Units/hour or BTUh.

When the climate is moderate, undersized ACs work well. In hotter weather, however, these systems may operate for more time than usual and find it difficult to maintain the temperature.

The rating information on the cabinet panel can help you to work out your system’s size. However, you will struggle to figure out if it’s a suitable size for your house.

A handful of aspects factor in when sizing an AC for a home. These include quality of manufacture and insulation, square footage, climate, etc.

The solution

There are a number of things you can do here. You might want to try to supply cooling in “hot spots”. The method is to add a ductless component to offer help in problem areas.

Alternatively, you can switch your AC with a suitably sized one. The best way is to seek the services of a professional qualified in air conditioning system repairs in Dubai. A pro can best analyze your residence and its optimum cooling ability.

Final words

You deserve a pleasantly cold environment. But, this isn’t the only reason for which you need to sort out your AC system repair issues in Dubai. The well-being of your system is also crucial. 

Sometimes, you may find that you have checked all options discussed above. But, your AC isn’t still cooling your home. In that case, it will be a good idea to ask for advice from someone who has been dealing with AC system maintenance in Dubai for a long time.
