Regular cleaning of the components of your air conditioner is essential for optimal aircon performance. It is recommended to contact an aircon service provider to perform cleaning of your air conditioner once every few months. If you are reluctant to hire an aircon technician, you can clean your air conditioner yourself to cut down on servicing and maintenance costs. This article is a step by step guide to cleaning your air conditioner.
If you are experiencing problems with your aircon, cleaning your air conditioner yourself may not solve the underlying cause of the problem. If the problem persists, our technicians are equipped to troubleshoot the problem, or perform a full dismantling of your aircon for a chemical overhaul if necessary.
First of all, you would have to turn the power supply off because you will have to clean the unit using water. Sometimes, the copper pipe of the air conditioner is improperly or poorly insulated and it can result in severe electric shocks. Once the power supply is off, you can start the main procedure.
The first step is to dismantle the exterior partitions of your air conditioner condenser unit. After lifting the fan grill from the condenser unit, you can use a vacuum cleaner to suck out any dirt and debris from the unit. The part that sucks in air should be unobstructed since any debris can block the airflow and reduce the unit’s cooling ability.
You can use a vacuum cleaner to suck out any dirt and debris from the blades and fins of the condenser unit. While cleaning the blades and fins, you should not use a pressure washer as it will damage the fins and they will bend. You can use spray cleaners instead which are readily available on the market.
After cleaning the fins, there may be some bending among them. Straighten any bent fins to ensure optimal air flow. You can use a small knife for this purpose. There are some fin straightening tools available on the market as well. The objective is to straighten the bent fins with a lot of care because they are quite a delicate component of the aircon.
You should now clean the area surrounding your condenser unit to finish up the cleaning process. It is necessary to clean the surroundings before cleaning the evaporator coils so no outside debris can reach the coil while cleaning.
The evaporator coil is located within the indoor unit. To clean the evaporator coil, you will have to open up some screws and bolts first. Once the coil is in your reach, use a soft brush to wipe away any dust from the coil. You can also use a discarded tooth brush for this purpose. After removing all the dust, spray the coil with a coil cleaner. These cleaners are available on the market and generate a foaming effect. Then, take the coil out of the unit from the drainage pipe without rinsing.
Once the coil spray cleaner is applied, clear the drain pipe using a mixture of water and soap. This mixture helps to clear the entire drain pipe of any blockages or mould.
The air filters, which you have dismantled in the first step, should be washed out now. You can use a commercial air filter spray or prepare a solution of soap and water. Once the mixture is evenly applied to the air filters, you can use a soft brush to clean out any dust particles. Run the filters under tap water to remove any soap and ensure they are fully dry before applying them back in the unit.
Once all the cleaning process is done, you can plug in the power supply adapter and turn it on. You should make sure that the power switch is turned off and the power supply adapter is out of the socket at all times before the cleaning is complete. Sometimes, even with the power switch turned off, you can face a severe electric shock from the copper pipe if the power adapter is not plugged out of the socket.
The above steps will help you to prolong the life of your air conditioner. This procedure works well for any sort of domestic or commercial air conditioner model. While you can easily perform it by yourself, you will need to look for a servicing company if there are more complicated issues that require troubleshooting. If you have a complex HVAC unit installed at your facility, an air conditioner servicing company will be well equipped and experienced to handle any problem in your unit.
