Heating and cooling performance depends on airflow and maintenance with issues like low refrigerant. A simple first step is airflow. Replace filters on schedule, keep supply vents open, and make sure return grilles are not blocked by furniture or rugs. Smart thermostats can help, but they still need the right settings and proper wiring. These checks can improve reliability and help catch problems like weak capacitors, dirty coils or worn blower parts before they cause a breakdown. Options like high-efficiency units or heat pumps can improve comfort and reduce energy use in some homes. With clear maintenance habits and timely service, HVAC systems can run more consistently through the year.
