How do I balance the temperature throughout my home?

Start by ensuring all supply vents and return registers are open and unobstructed by furniture or curtains. Check that your HVAC system is properly sized for your home. Improve attic insulation and seal air leaks around windows and doors. Consider a zoned HVAC system or smart thermostats with room sensors. Close blinds on sunny windows during summer. A professional can test your ductwork for leaks and balance the airflow.
