Maintaining Your Air Conditioner

By LawrenceGarcia

Regular maintenance is necessary for an air conditioner to work effectively and efficiently over its many years of service. In order to maintain a consistent level of air conditioning performance, it is important to not neglect necessary maintenance. However, energy consumption will continue to rise.

We’re confident that you’ll be pleased with our service when we fulfill your requirements for air conditioners in Singapore.

Air Conditioner Filters

Routinely changing or cleaning your filters is the most important task to maintain your air conditioner’s efficiency. Filters that are dirty or clogged can reduce airflow and reduce efficiency. Airflow can also be obstructed and air can flow through the filter, causing dirt to build up and contaminate the evaporator coil, reducing its heat-absorbing ability. You can reduce your air conditioner’s energy use by replacing a dirty or clogged filter. This will help you to lower your energy consumption by between 5% and 15%.

Central air conditioners have filters located along the length of the return duct. Common locations for filters are in walls, ceilings or the air conditioner. The filter is located in the grill and faces the room.

Coils for Air Conditioners

Over the years, dirt builds up on the condenser and evaporator coils of an air conditioner. The evaporator coil will not become soiled quickly if it has a clean filter. However, dirt will eventually build up on the evaporator coil. The dirt can reduce airflow and insulate the coil, which will decrease its ability to absorb heat. This problem can be avoided by checking your evaporator coil once a year and cleaning it as needed.

If the outside environment is too dusty, or there are trees nearby, outdoor condenser coils may also get very dirty. It is easy to see the condenser coil, and you can notice dirt on its fins.

Coil Fins


Aluminum fins found on condenser and evaporator coils can be bent easily and block airflow. A “fincomb”, a tool that can be used to comb the fins back to their original condition, is available from wholesalers of air conditioning.

Condensate Drains
Pass a stiff wire occasionally through the drain channels of your unit. A blocked drain channel can prevent the unit from reducing humidity. The resulting excessive moisture could cause damage to walls and carpet.

Window seals for room air conditioners
Each cooling season, check the seal between your window frame and the air conditioner to make sure it is in contact with the metal case. This seal can be damaged by moisture, which will allow cool air to escape your home.

Preparing for Winter
You can either cover or store your room air conditioner in winter. The unit will be protected from snow and debris by covering the outside unit of the central air conditioner.

Hire a professional

A professional service technician is hired if your air conditioner requires more maintenance than it needs, such as when the indoor temperature does not drop to a comfortable level. An experienced technician can diagnose and repair any problems with your air conditioner system.

The technician should:

  • Verify that you are using the correct amount of refrigerant
  • Use a leak detector to test for refrigerant leaks
  • Instead of illegally releasing refrigerant into the atmosphere, capture any that needs to be removed from the system
  • Seal any duct leakage from central systems.
  • Measuring the airflow through an evaporator coil
  • Verify that you have the correct sequence of electric control and ensure that both the heating and cooling systems cannot be operated simultaneously
  • If necessary, inspect the electric terminals and clean and tighten them.
  • Oil motors and oil check belts to ensure tightness and wear
  • Verify the accuracy of your thermostat.
