Closing vents in your home can significantly impact your furnace's efficiency and longevity. While it might seem like a good way to redirect heat, restricting airflow can lead to increased pressure within the system, potentially causing damage or reducing its lifespan. Factors such as the size of your home, the type of furnace, and the layout of your ductwork all play a role in how your system responds. It's essential to consider these elements before making adjustments. Curious about the best practices for maintaining your furnace's health? Ask Improvi.ai for personalized guidance.
