Tired of that old furnace driving up your energy bills?

The video opens with a shot of an old furnace in a basement, then transitions to close-ups of the furnace's interior with flames. It then shows two men loading a new furnace into a van, followed by shots of a new furnace and air conditioning unit outside a house. The final scenes show a technician working on a furnace and close-ups of the unit's labels. The pacing is quick, with frequent cuts between different scenes.
