1. Central AC repairs during the warranty period are handled by the retailer.
Warranties cover free on-site repairs for issues with the air conditioner, but are not responsible for problems such as dirty fins, high energy consumption, and odors during the air conditioner's operation. These are precisely the issues that lead to poor air conditioner performance, and thus, separate charges apply for these repair-related matters.
2. Air conditioner maintenance is just cleaning; anyone can do it.
This is a misconception; central air conditioning maintenance and cleaning is only a significant part of the overall maintenance, with the main cleaning areas including:
1. Air conditioner body shell and exposed parts, components prone to contamination;
2. Filter screen cleaning, a commonly cleaned area in most households.
3. The condenser, evaporator, and drain pan are the core components of air conditioner cleaning.
3. Neglect Preventative Measures
Central air conditioners should be preventive in their maintenance even when no faults have occurred. Generally, preventive measures include system inspections, troubleshooting, maintenance, and recommendations.
1. System inspection involves connecting the external machine to a computer via a unique interface. After the machine runs smoothly, all operating parameters are obtained through a specialized software. These parameters are then compared to normal operating values to check for any anomalies.
2. The investigation is based on identifying abnormal parameters from the inspection results, determining potential issues, and then conducting a thorough check and confirmation. This includes a re-examination of the initial system design and engineering installation.
3. Maintenance includes equipment repairs, major system overhauls, and necessary modifications, along with equipment usage recommendations, to ensure systems can operate smoothly over the long term. This requires maintenance units not only to have cleaning capabilities but also to possess specific skills in repair, design, and installation.
