Old or malfunctioning windows can significantly increase heating costs during winter. A simple paper test can help check window seals quickly. This method requires no special tools and can be done in minutes. If the paper test shows resistance, the window is likely sealed well. However, if it slips out easily, air leaks may be present, indicating the need for further inspection. Checking seals and hardware can reduce heat loss, and if issues persist, consulting a specialist is advisable. Regular checks before heating season can prevent unnecessary energy loss and improve home comfort.
