Regular air conditioner maintenance and service of parts like filters, coils, fins, drains etc. is very important for the effective operation of the AC unit. Negligence in the service and cleanup of AC results in reduced cooling capacity and damage to unit.


Here are seven very important air conditioner maintenance guidelines:

Regular maintenance & cleanup of air filters

Dirty and clogged air filters obstruct the normal air flow and reduce the cooling capacity of the AC system significantly. When the filter is very dirty, the air flowing inside bypasses the filter and carries dirt directly to the evaporator coil, thus soiling the cooling coils.

Air filter cleaning must be done at least once a month. Regular cleaning of air filters results in proper cooling. Air filter cleaning becomes very important if there are fur bearing pets inside home.


Cleaning of Evaporator coils

A clean air filter prevents the cooling coils from dust and dirt. But even then, some dirt and debris get deposited on the coils with time. This deposition and covering reduces the heat absorbing capacity of the coils, thus effecting the room cooling process. A yearly service and evaporator coil cleaning is very necessary.



Maintenance of condenser coil

The condenser and fan unit are located outside the home (in all types of AC). The outside dusty environment, falling leaves, rain and wind etc. soils the condenser coils. The dust and debris make it extremely difficult for the hot air and heat to dissipate outside.

This poor heat dissipation results in the heating of condenser and compressor (compressor is situated near the condenser coil). Thus, a yearly cleaning of condenser coil is very important for the condenser to work efficiently.



Cleaning Coil Fins

One can easily see the aluminum fins on the condensers and evaporator coils. The dust and debris get accumulated over the fins. The coil fins should be regularly cleaned to protect the evaporator and condenser.



Unclog the rear drain

If the drain at the rear end is blocked, then water that gets collected inside the AC finds no space to leave and drips inside the room from any opening. When the water inside the AC unit finds no vent, the humidity level inside the room also increases.



Cover up the compressor unit during winters

During winter season when your AC is not in use, cover up the compressor unit (as it is placed outside) with a cloth to prevent dust and dirt entering inside the unit.



Do not miss an AC service

Before the onset of summer season always call an ac service professional for a complete clean up and service of your air conditioner. Whenever you call an ac service professional, make sure that he checks up all the AC parts like coils, compressor, fins, filters, drains etc. and performs the necessary service.
