Why is my system freezing up?

When your cooling unit freezes up, there are a variety of reasons why it could be doing so. The most frequent 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 C-N-O Comfort Zone. Contact them at 636-578-1777 with any additional questions.
