Why is my cooling unit freezing up?

Your system could be freezing up for a number of reasons, but the most frequent are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something homeowners take care of; however, you should call the professionals at Main Heating & Cooling, Inc. at 586-731-0950 for other problems or if you have other questions or concerns.
