Why is my system freezing up?

When your cooling unit freezes up, there are a number of reasons why it could be doing so. The most common reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can take care of as a homeowner, but the others need to be fixed by a professional like those at Temp Air System Inc.
