Compared to traditional split air conditioners, central air conditioning is a type of air conditioner that has a longer usage time and higher comfort level. However, in the long-term use process, minor malfunctions of central air conditioning are common occurrences. This article introduces the maintenance tips for central air conditioning.

When we start the central air conditioning and find that it cannot operate, it is not necessarily a matter of which parts have major problems. Instead, we should look for the possible causes of the problems. For example, whether it is caused by abnormal power connection, and whether the central air conditioning is set to a timed mode, whether there is a power outage, or whether the fuse of the central air conditioning is broken. If it is caused by one of these factors, corresponding measures can be taken to handle it themselves. If the cause cannot be found, then professional staff can only be hired to come and repair it.

After turning on the central air conditioning, it is found that it cannot cool or heat, or the cooling and heating effects are not ideal. At this time, the user first checks whether the temperature design of the central air conditioning meets the requirements, whether the air ducts are blocked, whether the rooms and windows are open, and whether there are too many heat sources in the room. These are all possible reasons. If the central air conditioning lacks refrigerant, this situation may also occur, and it is necessary to add it in a timely manner.

Central air conditioning should be turned on frequently, even during non use seasons, once a month to prevent the lubricating oil in the compressor from condensing and prevent the compressor from getting stuck. The filters and fans of central air conditioning should also be cleaned regularly.

Many times, central air conditioning is not actually experiencing a substantial malfunction, but rather caused by some minor problems. Therefore, users need to first judge and search for solutions on their own. If they cannot solve the problem, they need to report it for repair in a timely manner.
