Is it illegal not to use central air conditioning and not to pay?

This situation should be considered illegal.

Article 273 of the Civil Code clearly stipulates: "The owner shall enjoy rights and undertake obligations for the part other than the exclusive part of the building; Do not give up rights and fail to fulfill obligations. " As far as the central air conditioner is concerned, the owner has the obligation to bear the operating expenses for the right to use the central air conditioner, and no owner can fail to fulfill the corresponding obligations such as paying the expenses because he has not used or abandoned the use.

When the central air conditioner is not used, there will be pipeline loss, line loss, preheating loss and so on. And there will be maintenance costs, which are not included in the property fees, so they should be shared by the owners.
