Baffling Breakdowns: The Main Reasons Why Air Conditioning Systems Fail To Work

Air conditioning systems are the lifeblood of homes in Dubai. Without it, indoor temperatures can soar to more than forty degrees celsius, which is why when they break down, it can be challenging and uncomfortable for people to stay inside. Knowing why the system fails is essential to hire HVAC maintenance companies to conduct routine servicing, which will help avoid these issues. Therefore, in this blog, we will examine the main reasons why an AC may not work. 

Frozen evaporator coils

The evaporator coil of an air conditioner contains refrigerant. It is responsible for taking in the heat from the surrounding air. It is necessary so that there is a continuous flow of warm air around the coils. If something is wrong with the airflow and the coil gets too cold, a layer of ice could form outside it. If this happens, the system will only release warm air to the room or none at all. Regular servicing will involve checking the coil to ensure there is no ice build-up and examining whether the component is working correctly. This will allow the AC to function without any issue. 

Leaking ducts

In Dubai, air conditioning systems tend to be mostly HVAC systems that connect the air conditioning of the whole house or apartment instead of small individual units. Air ducts play a crucial role in circulating the air within a building, and if there is a crack in a part of it, it could lead to cool air leaking out and getting trapped within the walls. 

Hence, there will be insufficient cooling, and it could lead to higher utility bills as the system will not be energy efficient. Sometimes, the air trapped within the walls could lead to dampness and mold formation, which could be hazardous to one’s health. AC repair companies will use special equipment to detect any leaks and fix them, thereby restoring cool air and keeping the house cool and safe.

Problems with the fans

Most air conditioning systems have two fans; one that blows air over the evaporator coil and moves the warm air through the outdoor unit’s condenser to be expelled outside the property. If one or both fans are not working as they should be, it could lead to a lack of airflow and AC issues.

The reason why they may not work can be attributed to one or more of the following: defective motors, not enough lubrication, excessive dirt or debris, or worn-out belts. A person can identify if there is an issue with their fan if it will not start when they turn the AC on, will not stop if they turn it off, the blades slowly rotate when turned on, or a rattling sound being emitted from the condenser unit. If they suspect an issue, they need to contact a professional to carry out the repairs. 

Air conditioning systems need to be treated carefully to ensure they will not have problems or break down. Regular servicing and AC cleaning are vital to keeping it operating smoothly.
