Air conditioner servicing includes not only fixing a malfunctioning air conditioner but also to doing all necessary maintenance jobs to prevent anything bad from ever occurring in the unit. If you want to keep your air conditioner in good condition, you need to do all servicing jobs that are included in the checklist below regularly.

Cleaning Jobs

Cleaning jobs include a series of air conditioner servicing tasks that you need to do to ensure the cleanliness of your air conditioner’s components and the unit’s efficiency. Here are parts that need regular cleaning.

  1. Filters

You need to make sure that your air conditioner uses working filters that will effectively prevent dirt and debris from entering the blower and evaporator compartments. Dirty filters are a sign of a bad filtration system. Clean or replace the filters regularly when they look dirty.

  1. Evaporator coils and condenser unit

You should also check the evaporator coils and the condenser unit outside. Dirty evaporator coils and condenser unit reduce efficiency. Clean them from dust, leaves, and other kinds of debris to restore your air conditioner unit’s efficiency.

  1. Drain pans and condensate drains

Your air conditioner releases moisture as a byproduct. It will develop into water that needs draining through the drain pans and condensate drains. Don’t allow the water to be trapped and mold and mildew to thrive by ensuring that both the pans and the drains are clean and free from clogging.

Refrigerant Checking

Low refrigerant prevents your air conditioner from working optimally and efficiently. Check the refrigerant level once a year or when your air conditioner doesn’t produce enough cooling effect. There are two things to do during the checking. Firstly, you need to check the refrigerant level to decide whether refilling is needed. Secondly, you need to check for any leaks that may occur along the refrigerant line and tubing. The leak may be easier to identify if you see icicles along the line. If the refrigerant line is leaky, hiring an air conditioner servicing professional might be necessary to fix the problem. Don’t let the problem persist because a low refrigerant level may cause the compressor to fail.

Drive Belt Checking

Several rotating parts inside your air conditioner unit, including the indoor blower and outdoor fan, use a rubber drive belt that may become unreliable due to wear and tear. Check the belt and decide whether it needs readjusting or replacing.


Lubrication is considered an essential air conditioner servicing task because your air conditioner unit consists of moving mechanical parts. If they are not properly lubricated, they may break due to friction and extreme heat.

Electrical Component Checking

You should check all of the electrical components of your air conditioner unit to make sure that they are in good condition. Check the cables, fuses, and circuit boards. Call an electrician or servicing specialist if you deem it necessary.

Test the Unit

After you’ve done all of the required air conditioner servicing tasks, you should test the unit to detect any potential problems. Check for noises, leaks, cooling effect, and anything else that determines the overall health of your air conditioner unit.
