Maintaining Air Conditioner
If the air conditioner will not be used for a long period of time, dry the air conditioner to maintain it in the best condition.
First dry the air conditioner thoroughly by operating in Fan mode for 2-3 hours and disconnect the power plug. There may be internal damage if moisture is left in components.
Secondly dry the inner components of the air conditioner again by running in Fan mode for 2-3 hours before using air conditioner again. This helps remove odors which may have generated from dampness.
You should make periodical checks to maintain the air conditioner properly. The indoor unit consists of the air filter, condensate drain pan, heat exchanger, condensate drain pipe and remote control. You should clean all the components once a year except the air filter that should be cleaned every month.
The outdoor unit has the heat exchanger on the outside of the unit that should be cleaned every 4 months; the electric components should be cleaned with jets of air once a year. Verify that all the electric components are firmly tightened once a year. The fan is to be cleaned once a year also.
These checks and maintenance operations are essential to guarantee the efficiency of the air conditioner. The frequency of these operations varies according to the characteristics of the area, the amount of dust and some other conditions. If the area of installation is very dusty, the described operations should be performed more frequently. It is important to know that these operations are recommended to be performed by qualified personnel.
