Why is my system freezing up?

When your cooling unit freezes up, there are a couple 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 fix as a homeowner, but the others need to be done by a professional like those at Alan Heating Air Conditioning, Inc..
