Why is my cooling unit freezing up?

Your system could be freezing up for a variety of reasons, but the most typical are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something you, the homeowner, can take care of; however, you should call the professionals at Schagrin Gas Company at 302-658-2000 for other problems or if you have other questions or concerns.
