How to Maintain Your Wall Mounted Air Conditioner

Wall Mounted Air Conditioner

An air conditioner is one of the essential appliances in a household. It makes the house comfortable by providing the right temperature depending on the weather. 

Modern air conditioning units offer many features that can give you ease and total comfort. However, no matter how good and expensive your unit is, it needs care and proper maintenance. Below are some important guidelines on how to maintain your wall mounted air conditioner.


Cleaning or replacing the filters of your air conditioning unit is an essential maintenance task to ensure your unit’s efficiency. Dirt and dust can clog the filter, blocking the normal airflow and significantly reducing the system’s efficiency.

Obstructed airflow allows the air to carry dirt right into the evaporator coil, reducing the heat-absorbing capacity of the coil. A clean filter can reduce your unit’s energy consumption by 5-15 per cent.

You need to clean or replace your air conditioning unit’s filter at least every two months during the warm season. You may need to clean it more often if the unit is in constant use, in dusty condition, or you have pets with fur.


The condenser and evaporator coils collect dirt over time. The amount of dirt the coil collects depends on the status of the filter; cleaner filters mean a longer time for the coil to collect dirt. 

The dirt insulates the coil impairing its ability to absorb heat. Checking the evaporator coil at least every year and cleaning it if needed can keep it in good condition.

On the other hand, outdoor condenser coils may collect more dirt if it is placed in a dusty environment or near foliage. The condenser coil is highly visible, and you can easily see if its fins are collecting dirt. You need to clean the part around the condenser unit to allow enough airflow around the coil.


The fins on the coils are made of aluminum and can bend easily, blocking the flow of the air through the coil. Installing fin combs can prevent the fins from bending.

Condensate drains

Clogged drainage prevents the air conditioning unit from reducing humidity. It may result in too much moisture that could bring discolouration to your carpet and walls. Letting a stiff wire pass through the drain channels occasionally prevents the drainage from clogging.

Professional maintenance

Once in a while, your wall mounted air conditioner needs to be checked by a professional technician. A highly-skilled technician can find and fix any issue in your air conditioning unit.

A technician can:

  • Check the level of the refrigerant.
  • See if the refrigerant is leaking.
  • Collect the refrigerant that must be removed from the unit and dispose of it properly.
  • Check and repair any leakage in central systems.
  • Check the airflow through the coils.
  • Test the electric control sequence, making sure that the cooling and heating system will not run at the same time.
  • Check the electric terminals, tighten and clean the connections, and coat it with non-conductive coating if needed.
  • Check belts for wear and tightness.
  • Oil motors
  • Check if the thermostat is still accurate.

Regular maintenance can keep your air conditioning unit running in good condition for a long time. While hiring professional maintenance services seems expensive, it will help you save a lot of money in the long run.
