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 homeowners take care of; however, you’ll want to call the professionals at O'Brien Heating & Air Conditioning at 610-626-2540 for other problems or if you have other questions or concerns.
