Clean the Area Around Your Unit: Keep the outdoor unit free from debris, leaves, and dirt to ensure proper airflow. Check Thermostat Settings: Make sure your thermostat is set correctly and consider upgrading to a programmable or smart thermostat for better energy management. Seal and Insulate: Properly seal and insulate your home to reduce the load on your HVAC system. Use Fans: Ceiling fans can help circulate air, reducing the strain on your HVAC system and improving comfort. Mind the Vents: Ensure all vents are open and unobstructed to maintain balanced airflow.
