Complete guide to AC cleaning: important precautions from choosing the cleaning method to maintenance
Contents
An air conditioner is an indispensable part of modern homes, especially in summer. After long-term use, dust and dirt will accumulate inside the unit. Regular air conditioner cleaning is an important part of keeping the system in good working condition.
Choose the right cleaning method
Residents should only handle filters and exterior surfaces that can be safely reached, as required by the manufacturer. Outdoor-unit cleaning involves the fins, electrical parts, supports and access points; do not wash it yourself just because it is visible, and never lean out of a window. Service staff will assess the work scope for both indoor and outdoor units.
Internal cleaning and refrigerant checks are different jobs. A properly sealed system should not be depleted on a regular basis, and refrigerant should not be added automatically during cleaning; if there is an abnormality, a technician familiar with the model should identify the cause, and any regulated procedures must be checked against qualifications separately.
During the cleaning process Notes
- Power-off procedure: before starting cleaning, make sure the AC power is switched off to avoid the risk of electric shock.
- Use the correct tools: Make sure to use suitable cleaning tools and detergents, and avoid chemicals that may damage AC parts.
- Protect the indoor environment: During cleaning, use plastic sheets or other materials to protect nearby furniture and floors from damage caused by cleaning agents or dirty water.
Maintenance recommendations after cleaning
- Regularly replace or clean the filter: The filter should be checked once a month, and cleaned or replaced depending on how often the unit is used.
- Inspect the drainage system: make sure the air conditioner's drainage pipe is clear and unobstructed to avoid water accumulation and bacterial growth.
- Monitor AC performance: after cleaning, check whether the unit runs more smoothly, and watch for unusual noise or odour.
