The efficiency and capacity of central heat pumps depend on sufficient airflow. There should be between 400 and 500 cfm (cubic feet per minute) airflow for every ton of a heat pump’s air conditioning capacity. Performance and efficiency deteriorate if the airflow is less.
According to studies conducted by Energy Star, 50% of all heat pumps have major problems with incorrect refrigerant pressure, inadequate airflow and leaky air ducts. These factors influence the performance of the whole heat pump system, forcing ...Continue Reading →
