What are the common problems in Aircon?


 Like any complex machinery, aircons are susceptible to problems and malfunctions. Understanding the most common issues with aircons and how to troubleshoot them can help homeowners avoid costly repairs or replacements.


Dirty Air Filters

Dirty air filters are one of the most common issues with aircons. Over time, air filters can accumulate dust, dirt, and other debris, which can reduce airflow and cause the aircon to work harder than necessary. This can lead to higher energy bills, reduced cooling efficiency, and even system failure. Regularly cleaning or replacing air filters can help prevent this issue.


Malfunctioning Thermostat

The thermostat is the control center for an aircon, regulating the temperature and cooling settings. A malfunctioning thermostat can cause the aircon to work improperly or not at all. For instance, if the thermostat is not calibrated correctly, it may not send the right signals to the aircon, resulting in the unit running too frequently or not frequently enough. Homeowners should check their thermostat's batteries and settings to ensure everything is in working order. If unsure, it's best to contact a professional technician to diagnose and fix the issue.


Leaking Refrigerant

Refrigerant is the substance that cools the air in an aircon unit. If there is a leak in the refrigerant line, it can cause the refrigerant to escape, which reduces cooling efficiency and causes the aircon to stop working altogether. Refrigerant leaks can also pose health and environmental hazards, making it essential to address this problem promptly. If homeowners suspect a refrigerant leak, they should contact a professional technician to diagnose and repair the issue.


Dirty Condenser Coils

Condenser coils remove heat from homes and release it outside. However, if the coils are dirty or clogged, they can't do their job efficiently, resulting in reduced cooling efficiency and higher energy bills. To clean condenser coils, homeowners should turn off their aircon, remove any debris or foliage around the unit, and gently clean the coils with a soft brush or vacuum cleaner.


Clogged Drainage System

Aircon drainage systems remove excess moisture from the air and drain it away from homes. If the drainage system becomes clogged or blocked, it can cause water to back up into the aircon, leading to system failure and water damage. Homeowners should check the drain line regularly and clean it out with a mixture of water and bleach if needed. If the issue persists, a professional technician should be contacted to diagnose and repair the problem.


Maintaining an Air conditioning system is essential for comfortable indoor temperatures, but regular maintenance and troubleshooting are necessary to keep them running efficiently.
