Why is my cooling unit freezing up?

Your system could be freezing up for a number of reasons, but the most common 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 Clean Air HVAC at 925-689-7017 for other problems or if you have other questions or concerns.
