Most Common Problems With Split Air Conditioners

The only time of the year when air conditioners are mostly used is during summer and this is the time when you would want your air conditioner to be in the best possible condition. Window/split air conditioners have become a necessity in every home today. If not properly maintained and regularly serviced, your air conditioner can start showing signs of failure.


We list down 4 most common split AC problems and how you can fix them.

AC Maintenance


Lack Of Cooling

Split air conditioners do not take too long to cool the room but in spite of keeping it on for hours if there is no proper cooling, the reason could be a dirty air filter or a blocked condensate drain. Air filters protect the AC from dust in the air. It may be easy to clean an air filter in a Window AC but for split AC, you will need help from a professional.

Air filters trap dust and debris that is pulled into the ducts and if they’re not frequently cleaned, they remain clogged and affect the cooling process. We recommend getting the air conditioner serviced twice a year for better performance and to avoid any problem during summers. Another possible reason for lack of cooling could be ice formation around the coils or a dirty outdoor compressor for which you will need help from a professional.

Low On Refrigerant or Gas Leakage

If the air conditioner is not properly cooling, it’s also possible that it’s low on refrigerant. This either means that it was undercharged, or there is gas leakage in the split air conditioner. This is a more common problem with residents located around coastal regions or anywhere close to sewage, where air pollution is high. In this case, a professional will need to check for any leaks before adding more refrigerant, as problems with leaks will persist, and they can be harmful to the environment.

Remember, when the air conditioner has a refrigerant issue, it works harder and runs longer to keep your room at the set temperature. So do not use the appliance for hours thinking it may start cooling or it can lead to increased electricity bills. However, you can avoid costly AC repairs and keep your AC functioning at peak performance with regular servicing.


Faulty Compressor

When the compressor stops working, it is an indication of a burned wire, defective start capacitor, or a defective compressor itself. In this case, you will need to get the condenser coil cleaned, check the capacitor, and replace the compressor if it is found faulty. A compressor takes care of the gas flow between the evaporator and the condenser. Hence, if the condenser is damaged, the AC stops blowing cool air. A compressor costs anywhere between Rs 6,000 to Rs 10,000, depending on the brand.

AC Maintenance
AC Keeps Turning On & Off Constantly

If your air conditioner keeps turning on and off, it’s best to switch it off till you don’t get it serviced. Most likely, the evaporator is dirty and the condenser is dirty or blocked. A dirty filter restricts airflow and restricted airflow causes more problems, including a frozen evaporator coil. Especially, before and after summer, it’s important to change the air filter for better cooling and overall performance. Also double-check the thermostat settings yourself and see if the timer setting was turned on and change it accordingly.

An AC requires regular maintenance to keep it functioning efficiently, so it is a good idea to get your appliance covered with Onsitego’s Comprehensive AMC plan. With Onsitego AMC, you can get up to two years of repair and maintenance support, including two preventive maintenance visits a year, unlimited repairs (including the cost for labour, service, and transport), free gas charging (if required), and the cost of spare parts. If anything goes wrong, you can be assured of quality service.
