Why is my cooling unit freezing up?

When your cooling unit freezes up, there are a number of reasons why it could be doing so. The most typical reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can change as a homeowner, but the others need to be done by a professional like those at Hammack Service Company.
