An Update from Stone Heating and Air - September 9, 2022

commercial service call for no AC. Customer noticed that there wasn’t any air flowing out of the supply registers throughout the building. Upon inspection found that the coil was frozen over. This was caused by the blower capacitor going bad. Without airflow over the coil the refrigeration causes the coil to freeze over. Without air circulating through the system the coil will freeze over pretty quickly. With a new capacitor and a new contactor the system is working as it should for the owner.
