What Are The Common Causes Of Air Conditioner Failures?

Air conditioning is a necessity in hot regions, and if your air conditioning system breaks down, life may become miserable. It’s crucial to perform routine causes of air conditioner failures to keep them in good operating order because ac repair can be costly. Knowing some of the most common problems that might affect your air conditioner is also wise.

Although expert servicing and ac maintenance springs are necessary to guarantee the long-term performance of your air conditioner, there are numerous steps you can take to avoid failure and even repair some issues on your own.

Causes Of Air Conditioner Failures

1 – Drain Blockages

Your air conditioner must dispose of all the moisture it takes from the air. It is intended to be eliminated from the area via a drain line, a pan, and a drain. The water might back up and harm your system if the line, drain, or pan becomes full. You can also experience water leaks that harm your furnishings, ceilings, and walls. If you overlook mold development straight away, it will gradually spread.

 2 – Reduced Refrigerant

The substance the ac installation in Dubai utilizes to extract the heat and moisture from the air in your house or place of business is known as the refrigerant. You may not have enough refrigerant to adequately cool the air if your system develops leaks in the refrigerant lines. Unfortunately, switching the refrigerant is not enough to properly fix this air conditioner problem. Finding the leaks and fixing the holes in the lines requires the assistance of an AC maintenance specialist in terms of Air Conditioner Failures, which can occasionally be a time-consuming and costly process, mainly when there are several leaks.

3 – Leaky Ducts

The cooled air from the air conditioner is distributed throughout your area through the ductwork that passes through your walls and ceilings. However, that pricey chilled air can end up inside your walls, where it is useless if there are holes or cracks in the ducts (which can be caused by mice or negligent workers). Of course, your air conditioner has to work harder, which increases your energy costs.

4 – Iced Evaporator Coils

The evaporator coil in your air conditioner, packed with refrigerant, is in charge of soaking up heat from the air like a sponge. Although it may seem contradictory, those coils require warm air to move around them to function effectively. A layer of ice may accumulate outside if the airflow is disrupted and the evaporator coil becomes too cold.  This may cause air conditioner failures. When that occurs, the air flowing from your air conditioning supply registers will be heated or won’t come. Such a situation requires immediate services.

 5 – Contaminated Condenser Coils

Condenser coils in your unit’s exterior unit exhaust the heat that has been taken from the air outside the structure. The condenser coil won’t function properly when coated in dirt and filth. When heat transfer is inhibited, your unit must work harder to do its task, which increases part wear and may result in system failure.

6 – Fan Issues

Air is blown over your unit’s evaporator coil to chill the air in the room, and the air is blown over the outdoor unit’s condenser to expel heat into the outside air. If any of those fans aren’t functioning correctly, you have inadequate airflow and issues with your air conditioner. This might be caused by a defective motor, a lack of oil, worn belts, or too much dirt and debris. If you ignore the issue, compressor or the whole air conditioner failures could result, which is frequently the end of your air conditioner.

7 – Issues with Thermostats

Your old dial-type thermostats, especially, may not be calibrated appropriately. Which would prevent your air conditioner from receiving the proper commands from the control system. Your thermostats can be easily replaced or recalibrated to solve this issue. It cannot be easy to program new thermostats, which might be set incorrectly. If you still have one, verify the directions in your thermostat’s manual to verify the settings are proper.
