Simply call in the professionals at Air of Excellence to find out why some rooms are too hot and others are too cool. Airflow problems can be caused by a number of things. One can be a dirty filter, coil and/or blower, which hampers the air flow as it passes through the air handler. This causes the air to die off in the outer branches of the duct system. A second problem can occur when the ductwork becomes loose. This can be fixed with a minor reattachment of the ductwork. In some cases, your system will need to be replaced with an advanced climate control system, also known as a zone system. The technician at Air of Excellence will make a recommendation to you after he inspects your system.
