Why is my system freezing up?

Your system could be freezing up for a couple 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 any homeowner take care of; however, you should call the professionals at PWA Heating & Cooling Inc at 815-768-6656 for other problems or if you have other questions or concerns.
