With the development of the social economy, people in the non-district heating zone have growing demands to deal with the harsh winter indoor environments and yearn for a comfortable indoor environment in the winter. Relevant studies on heating demand and behavior are based on questionnaire surveys whose options are subjectively made by researchers. That would lead to biased results for occupants who can only show complaints following the researcher's thinking. Apart from that, the options that researchers designed were also not abundant enough. The social listening method is applied in this study that reviews relevant discussions on heating issues based on the community social questions and answers. The method collects 21 653 pieces of data in the form of answers and comments expressed spontaneously by different users. It also focuses on the 3.19% dissatisfaction within the indoor environment of the five categories and found that complaints during winter are much more trivial than researchers had thought before. At the same time, online users tend to describe equipment service time as actions-activated. That will provide a reference for designing questions and options to the questionnaire in related research supplementing the traditional passive questionnaire survey.
