What Are The 5 Most Common Problems With Air Conditioners?

Air conditioning is a must-have, particularly in hot climates, and life can become intolerable if your air conditioner breaks down. Since repairs can be expensive, it's important to maintain the air conditioner in good working order by doing routine maintenance. It's also a smart thing to be familiar with some of the more popular issues that can happen with your air conditioner.


Improper service is one of the most common air conditioning issues. Cover your home's windows and exterior doors while your air conditioner is on. Isolate the room or a group of related rooms from the rest of the house as much as possible by using a room air conditioner.


  • Clogged Filter


A clogged or dirty filter is one of the most common causes of air conditioner failure. Replace the air filter according to the manufacturer's recommendations.


Others are used once a month, some three times a year, and others are reusable and can be washed as they get dirty. Checking if the light moves through a filter to see if it has to be washed is one way to tell.


It's time to disinfect it if it isn't already. Filters that are dirty can only limit air flow but can also cause the air conditioner to freeze.


  • Thermostat


Another simple cure is to ensure that the thermostat is switched on, that the interior is clear, that it is level, that it is not polluted by sunlight, and that it is set to the right temperature. If the situation persists, there might be a more serious problem.


  • Refrigerant Leaks


If the air conditioner is low on refrigerant, it was either installed incorrectly or has a leak. If it leaks, merely adding more refrigerant would not solve the issue.


Any leaks should be repaired by a qualified contractor, who should then inspect the repair and charge the device with the proper amount of refrigerant.


Remember that the air conditioner's performance and reliability are best when the refrigerant charge meets the manufacturer's specifications and is neither undercharged nor overcharged. Leaks of refrigerant can also be hazardous to the climate.


  • Compressor


To carry out heat exchange, the compressor contributes energy to the refrigerant and propels it through the coils. The air conditioner would not cool your home if the compressor fails.


The compressor will run hot and finally seize if there isn't enough refrigerant. If there's so many, the refrigerant will leak back into the compressor, causing it to collapse.


  • Fans


A fan blows air over the evaporator coil of your unit to cool it, and another blows air over the condenser of your outdoor unit to remove the absorbed heat outside the room.


You'll have bad ventilation and air conditioner issues if one of those fans isn't running properly due to a broken engine, lack of lubrication, rusty belts, or too much dirt and debris. If you ignore the problem, it could lead to compressor failure, which is usually the end of your air conditioner's life.

Other common issues with existing air conditioners include improper installation, repair practices, and servicing. A central air conditioner installed incorrectly will result in leaky ducts and poor airflow.


The refrigerant charge (the volume of refrigerant in the system) does not always correspond to the manufacturer's requirements. The stability and reliability of the device would be harmed if adequate refrigerant charging is not done during installation.


Unqualified service technicians also fail to detect refrigerant charging issues and, in some cases, exacerbate current issues by supplying refrigerant to an already complete device.


Manufacturers of air conditioners are known for producing tough, high-quality goods. Check the fuses or circuit breakers first if the air conditioner fails. Allow for a five-minute cooling period before resetting any breakers.


On a hot day, the high-pressure limit switch in a central air conditioner's compressor could have tripped; reset it by pressing the button in the compressor's access screen.
