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 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 change as a homeowner, but the others need to be completed by a professional like those at Tokay Heating and Air Conditioning.
