The neighbors downstairs have no windows, which makes the property management extremely cold.

In this case, the property will not be in charge.

If the neighbors downstairs have no windows, resulting in a particularly cold room, the property will not directly intervene and take measures. Because property companies are usually responsible for managing and maintaining property facilities, equipment and services, and providing a comfortable and safe living environment. Correctly speaking, this problem does not belong to the category of property management.
