Hope everyone is well!
During freezing rain many heatpump systems can freeze over the top of unit where fan blows cold air out. This can cause issues with fan motor,blade etc. During this period you can opt to run system in emergency heat mode. This runs 2nd stage heating strips only and keeps outdoor unit off. After storm has passed, you can just switch back to regular heat mode. If you are concerned about a high bill this may not matter because most heatpump will already be using heat strips anyway due to this extreme weather.
Also after a power outage it is highly recommended that once power is restored keep system in emergency heat mode for around 6 to 8 hours to prevent compressor damage. Heat pumps are designed to operate in cold weather and compressors have built in heaters we call crank case heaters. This prevents liquid refrigerant from migrating into the compressor and damaging compressor. The issue is with power being out for a few days this heater will not have run, so when power is restored it is not uncommon to have customers that have bad compressors. To prevent this just run system in emergency heat and allow compressor to warm back up. Normally 6-8hours then switch to regular heat . Hope this helps!
