How to maintain and clean an air conditioner
Contents
AC demand is high in summer. Learning how to clean and maintain your AC regularly helps keep it in good working condition. This article provides a guide to AC cleaning and maintenance.
Why should air conditioners be cleaned regularly?
During operation, an air conditioner draws in dust. This build-up may affect ventilation efficiency. Excessive dust accumulation may also place extra load on the system. Regular cleaning is key to maintenance.
Steps for air conditioner cleaning and maintenance
1. Power-off preparation
Before cleaning, first make sure the air conditioner is switched off to avoid electric shock or damage to the circuit.
2. Clean the filter
The filter is one of the parts that collects dust most easily in an air conditioner, so it should be cleaned every two weeks to one month. After removing the filter, use a vacuum cleaner to remove surface dust, then rinse it with clean water. For heavy dirt, a neutral cleaner can be used to assist cleaning. After washing, place it in a cool, shaded area to dry.
Check refrigerant pressure (professional equipment required).
Insufficient refrigerant affects cooling performance, so checking refrigerant levels regularly is part of maintenance.
4. Clean the evaporator and condenser
This part is recommended to be handled by a professional technician. During cleaning, a professional cleaning agent will be sprayed and used to wash the evaporator and condenser, which helps improve heat exchange efficiency.
5. Clean the drain pipe
Air conditioners produce condensate during operation. If the drain pipe is blocked, water may leak inward or drip down. Regularly checking and cleaning the drain pipe can prevent this problem.
6. System check
Inspect all systems of the air conditioner, including the circuit, fan and control system, for damage or ageing.
