To maintain an air conditioner regularly we need to check the filter, coil, and fins. So that it will serve us throughout the year with the best performance. By neglecting the necessary maintenance, it decreases it’s performance with less efficiency. So it should be maintained properly. So that, it will function properly with smoothly. If there will be any defect in AC then it will be the failure to provide cold air after a long time. Hence it will consume more electricity than usual electricity.  

 Some tips for maintaining an AC 

• Air conditioning filters.  

The most important thing that will increase the efficiency of the air conditioning (AC) is to replace the air filters regularly or keep them cleaned. Closed and dirty filters reduce air efficiency and reduce the efficiency of the working system of an AC. Also, when airflow in the system of obstructed, air can enter the filter and deposit dirt directly on the evaporator coil, impairing the coil's heat absorption capacity. If it is dirty then we have to change it to get better service.  

• Check air conditioning coils 

Air condition (AC) evaporates coils and conditioning coils have accumulated dirt over months and years of service. The coil collects dirt after functioning over time. This dirt reduces the air efficiency as well as the heat absorption capacity. To overcome this problem the coil has to be changed every year Timely. If the outside environment is dusty or there are leaves and waste materials available nearby, the outside coils also get damaged. We can easily see it and clean the dirt off the fin. Keeping our surrounding area free of debris and at least 2 feet (0.6 m) of foliage allows for adequate airflow around the condenser. 

• Coil fin 

Aluminum fins on evaporator and condenser coils can easily bend and block airflow through the coil. Air conditioner sellers sell a coil that helps it work as before. 

• Condensate Drain 

Sometimes you run a hard wire through the unit's drain channel. Butt drain channels prevent a unit moisture loss. So that it adds more moisture to the wall or carpet. 

• Window seal for room air conditioner  

At the beginning of each cold season, check the seal between the air conditioner and the window frame to make sure it contacts the metal case of the unit. Moisture in it can damage this seal, preventing cold air from escaping the app's housing. 

• Hiring a professional  

Hire a professional AC repair technician to maintain your AC properly. A well-trained technician will troubleshoot your air conditioning system. Now there are too many AC repair centers are available in Kolkata which has many experienced AC repair technicians. Many AC repair centers in Kolkata provide AC repair service at the doorstep of their customers.

Now AC repair in Kolkata is very easy but it is very difficult to find a genuine and experienced AC- repair technician in Kolkata.

The technician should know about these things for properly maintaining the AC. 

• They should check the correct amount of refrigerant.  

• Measuring the airflow through the evaporating coil.  

• Verify the correct electric control and you should make sure that the heating system and cooling system are operating.  

Conclusion - So it is very important to maintain your AC with an expert and professional AC repair technician for getting the best output smoothly. It is very difficult to survive in Kolkata without an AC for the effect of global warming and boundless construction works.
