With Singapore’s hot and humid climate, having a properly functioning air conditioner is a must. However, without regular aircon maintenance in Singapore, AC units lose efficiency and break down more frequently. Implement these 10 aircon servicing tasks to extend the life of your system.
#1 – Replace Air Filters
Dirty clogged filters restrict airflow, forcing your AC to work harder and run longer. Mark your calendar and replace filters every 3 months. For window unit filters, soak in water and mild detergent then rinse thoroughly. Disposable panel filters should be swapped for new ones. Opt for higher quality MERV 13 filters that trap more dust and allergens. Properly replacing filters prevents strain on the motor and maintains cooling capacity.
#2 – Clean Wall and Ceiling Grilles
Dust and dirt clump in wall and ceiling outlet ventilation grilles, impeding optimal airflow. Twice a year, use a vacuum crevice tool to remove built-up debris from outlet grilles. For stubborn dirt, use a small brush dipped in warm soapy water and gently scrub the grille clean. This allows cooled air to flow freely into the room.
#3 – Disinfect the Aircon System
Mould, bacteria and microbes thrive in the cold, damp AC system over time. To sanitise the inside of units, use an eco-friendly aircon cleaner. Follow directions to mist cleaner into wall vents to penetrate coils, pans and ducts. This eliminates germs circulating through the cooling system.
#4 – Flush Condensate Pipes and Pans
The AC’s condensate drain pipes channel away collected moisture. Algae, bacteria and sediment eventually clog these pipes causing water to back up and overflow. Once a year, pour a mix of bleach and water or an enzyme cleaner down the condensate pan and pipes to clear gunk and keep water flowing freely.
#5 – Check and Recharge Refrigerant Gas
The refrigerant gas in AC units allows efficient heat transfer for cooling. But gas slowly leaks over the years from seals and connections. Have a technician annually check levels and top up refrigerants to optimise chemical levels for peak performance. Proactive recharging prevents compressor strain.
#6 – Clean Evaporator Coils and Fins
For proper airflow, evaporator coils and fins must be clear of debris, mould and dirt buildup. Use a special high-pressure coil cleaning foam spray and thoroughly rinse to remove accumulated grime without damaging the fragile coils. Clean coils allow chilled air to properly pass into your home.
#7- Inspect for Refrigerant Leaks
Along with regular recharging, aircon general servicing technicians should check refrigerant lines yearly for any leaks. Tiny leaks slowly lower AC efficiency over time. Any identified leaks can then be sealed to prevent gas loss and the need for frequent refilling.
#8 – Test and Replace Capacitors
Capacitors help start the AC motor and run components like the fan. Bad capacitors prevent the AC from turning on or cause starting issues. Inspect annually for bulging or leaking, and replace any faulty capacitors.
#9 – Lubricate the Reverse Valve
The reverse valve directs refrigerant flow for heating or cooling modes. Over time, valves can seize up if not properly lubricated. Light oil applied yearly keeps the valve working smoothly and quietly.
#10 – Insulate Ductwork
Insufficient insulation around ducting wastes cooled air before it circulates through your home. Ensure ducting joints are fully sealed with durable insulation tape and wrap any exposed pipes and connections. Also, inspect existing insulation around ducts for gaps or tears and patch with new insulation as needed. Replacing old or damaged insulation improves efficiency by preventing cooled air from leaking out before entering living spaces.
