Residential Air Conditioning Service in Singapore

Residential air conditioning service in Singapore – air conditioner filters, coils, and fins require regular maintenance in order for the equipment to operate effectively and efficiently over its many years of service. Neglecting necessary maintenance can result in a persistent decline in air conditioning performance while energy usage steadily increases.

Air Conditioner Filters

The most important residential air conditioning service in Singapore task to ensure the efficiency of an air conditioner is to regularly replace or clean its filters. A clogged, dirty filter can reduce airflow and significantly reduce system efficiency. Additionally, when airflow is blocked, the air bypasses the filter and deposits dirt directly into the evaporator coil, impairing the coil’s ability to absorb heat. Replacing dirty, clogged filters with clean ones can reduce your air conditioner’s energy consumption by 5 to 15 percent.

For central air conditioners, the filter is usually located somewhere along the length of the return air duct. Common filter locations are on walls, ceilings or the air conditioner itself. The filter of the room air conditioner is installed on the grill facing the room.

Some types of filters are reusable; others must be replaced. They come in many types and efficiencies. During the cooling season, clean or replace the filters of your air conditioning system every one or two months. If your air conditioner is heavily used, dusty, or you have furry pets in your home, you may need to pay more attention to the filter.

Air Conditioner Coils

Residential air conditioning service in Singapore – coils and condenser coils of air conditioners can accumulate dirt over the course of months and years of use. A clean filter prevents the condenser coil from getting dirty quickly. However, over time, the condenser coils will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check the evaporator coil annually and clean it as needed.

Outdoor condenser coils can also get very dirty if the outdoor environment is dusty or if there are leaves nearby. You can easily see the condenser coil and watch for dust buildup on its fins.

You should minimize dust and debris near the condenser unit. Your dryer vents, fallen leaves, and lawn mowers are all potential sources of dirt and debris. Clean the area around the coil to remove any debris and trim the blades to at least 2 feet (0.6 m) to allow adequate airflow around the condenser.

Coil Fins

The aluminum fins on the evaporator and condenser coils are prone to bending and can block airflow through the coils. Air conditioner wholesalers sell a tool called a “fin comb” that can comb these fins back to their nearly pristine condition.

Condensate Drains

Occasionally run hard wires through the drain channel of the appliance. Clogged drain channels prevent the appliance from reducing humidity, and the resulting excess moisture can discolor walls or carpets.

Window Seals for Room Air Conditioners

At the beginning of each cooling season, check the seal between the air conditioner and the window frame to make sure it’s in contact with the unit’s metal casing. Moisture can damage this seal, allowing cold air to escape from your house.

Preparing for Winter

In winter, either cover your room air conditioner or remove it for storage. Covering the outdoor unit with central air conditioning will protect the unit from winter weather and debris.

Hiring a Professional

Hire a professional service technician when your air conditioner needs more than regular maintenance, such as when it doesn’t bring the indoor temperature down to a comfortable level. A trained technician will find and fix problems in your air conditioning system.

Technicians should:

Check that the amount of refrigerant is correct
Use a leak detector to test for refrigerant leaks
Capture any refrigerant that must be removed from the system and not illegally discharged into the atmosphere
Check and seal pipeline leaks in central systems
Measure airflow through evaporator coils
Verify correct electrical control sequence to ensure heating and cooling systems cannot operate simultaneously
Check electrical terminals, clean and tighten connections, apply non-conductive coating if necessary
Oil the motor and check for belt tension and wear
Check the thermostat for accuracy
