I have a heat pump system (installed last year). Once in a while, unpredictably, the pipes freeze up and the cooling stops working.
Does anyone know why these pipes might freeze?

The two biggest causes of icing refrigerant lines are lack of refrigerant and a blocked evaporator coil. Since your system is new, neither of these seems likely. I am guessing that you either retained your existing air handler or the existing refrigerant lines.
In this case, the old refrigerant lines may well be leaking, or the old evaporator coil could be plugged. A third option is to look at air flow. A plugged filter, or an obstructed return or supply duct will also cause this symptom.
There are mechanical failures that can occur within the heat pump system relating to the accuator piston or tx valve that is used to atomize and control the flow of the refrigerant in the air handler, or reversing valve and accumulator leaks or malfunctions in the condensing unit.
If your system is still under warranty, I would not hesitate to have the installer address what could be a very serious problem that could cause extensive damage to your equipment.

You probably need to cover them with armaflex or an extra heating coil.You can get either one of these at Loews or Home depot.If the problem persists you should contact an HVAC specialist or a plumber so that the pipes don't burst and your house gets damaged.Pipes can burst anywhere and not just where they freeze because the expansion of ice creates upstream pressure throughout the system.As much as 1400 psi.No residential plumbing is rated for anywhere near that so address the problem before it becomes a big and costly problem.

the pressure of the pipes inside affect the temperature of them, if the pressure is too low then it gets very cold and will freeze up...if the unit doesn't cool very well, then you need to get your pipes checked for a leak. But you are definetely low on Freon.

nope,,,not normal, you either have a dirty air filter or inside coil or it is low on freon,, check filter and coil first ,, if it is clean than call service tech to get them to add freon at proper level in unit,,,,
