Why is my cooling unit freezing up?

When your cooling unit freezes up, there are a couple 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 fix as a homeowner, but the others need to be completed by a professional like those at Pinnacle HVAC LLC.
