Solution

A house needs to be well ventilated for the comfort of its residents and for the wellbeing of the building. A house with poor ventilation can retain moisture and be draughty or airless. Warm air is lighter than cold air hence warm air passes out of your home through ventilators. Accordingly, without ventilators, warm air will not pass out, and the house will remain warm.
