Have you cleaned the filters on the indoor unit. Check the evaporator(in door unit) coils for build up and debris. Check the out door unit coil for leaves and debris. IF they all are clear. Could be low on refrigerant, faulty metering device or a blockage in the refrigeration system.

Yes, if the filters are clean, the coils are clean, and it is still freezing up in cooling mode, then it is low on refridgerant.

SOURCE: Will Not Heat
On the outdoor unit the fan should not be running, on the indoor unit the fan should be running. If you then check the outdoor unit with fan not running, you should be able to hear clearly that the compressor is actually working. If this is all correct, it is possible that your fourway reverse valve is seeping and needs to be replaced.

Depending on what type of Thermostat you have, it is usually as simple as setting a jumper for Electric heat instead of gas.
If you have a digital Thermostat then turn off the power to the Air handler and remove the thermostat. Look closely at the small jumpers and make sure your jumpers are set to elect. and not gas so the fan can run in heat mode.
If you have a standard heat cool mercury switch then same as before with the power and unscrew the thermostat, and where the yellow wire is connected if there is a factory with on the yellow, then move the factory wire to the (A) and put the yellow wire back on the (Y).
