Proper air conditioner maintenance ensures that the system is providing efficient cooling and heating all year round.

This may sound like an added cost but proper maintenance prolongs the life of an AC unit, thus helping users save thousands on unwanted repairs or replacement.

In this blog, we’re sharing a few technical knowledge in air conditioning maintenance.

  1. Condenser. Your air conditioner’s condensing unit is typically positioned outside the property on a concrete slab. The condensing unit is composed of the compressor, fan and the condensing coils. As the air conditioner cools the interior, the condensing unit rejects heat by blowing the fan over the condensing coils. Any blockage between the fan and the airflow of the condenser will affect the performance of the air conditioner.If you find leaves, dirt, grass or any material stuck to the coils, get a brush and gently remove them. Remember to switch off the unit and disconnect from the power supply before cleaning the condenser.
  2. Evaporator. It is advisable to clean the evaporator at least once a year. Remove dirt from the evaporator coils with a brush or a wet cloth.
  3. Filters. Just regularly cleaning and replacing air filters will improve the efficiency of any air conditioning system. It is advisable to change/clean filters at least once a month. If there are pets at home, this should be done more frequently. Wash of the dust in the filters with water or a vacuum cleaner.If the filters are extremely dirty, wash them with lukewarm water and mild detergent. Then dry in a shaded area, away from direct sunlight.
  4. Refrigerant. If the AC unit doesn’t have enough refrigerant, the AC unit’s cooling effect is low. Check the system’s coolant lines, which are running from the condenser unit outside to the evaporator inside the property. Damaged or worn insulation needs to be replaced.
  5. Ductwork. For central air conditioning units, make sure that there are no cracks or loose joints in the ducts. If necessary, use a sealant to seal the breaks. Also, make sure that there is no furniture blocking the vents inside the property.
  6. Cooling Fan. A dirty fan can sometimes affect the air conditioner’s performance. Check for any debris. Clean the fan using a vacuum cleaner and a soft cloth. Remember to check if the fan blade is screwed tightly on the motor shaft. Loose blades affect the fan’s operation and cause it to run noisily.
  7. Remote control. Check the remote control display to see if it’s working. If not, you may need to change the batteries.

Over time, air conditioning systems are going to show some wear and develop problems that will affect their efficiency. Regular upkeep of AC units and taking preventive measures will allow users to spot minor issues and take action before they turn into bigger problems and lead to costly break downs.
