If you have a Heat Pump and the coils are frozen outside, turn the thermostat to Emergency Heat. The heat pump will not work below 35 degrees (outside temperature, I'm not sure if it is 35-40 degrees).
Know if it is a straight A/C unit, then there might be a problem. Change your filter and watch the system for a little while. If it is still freezing up, call your local HVAC Contractor and schedule a service call. You might have a dirty evap coil or low on freon, etc.

Heat pumps do this when around freezing temperatures.Depending on the make of the unit they have differrent types of defrost timers.Its quite normal unless it does not go into defrost.If it is a straight A/C unit and the compressor is building ice on it you need to call service tech asap.turn unit off until tech checks it out.

The unit has a defrost cycle that may not be working. There is a defrost timer that sometimes goes bad. If it stays iced up your electric bill will suffer because the unit will use supplemental resistance heat.
You would be ahead to have it checked out.

It is most likely low on freon...or the other gas they are using now days that took the place of freon. Probably have a leak in the system.

Lack of air circulation. Change out filter, turn controls to fan only and let run for about half hour to an hour. this should unfreeze your lines. You must keep filter clean

You most likely have a coolant leak. Needs professional service, usually means you need a new one.
