You need to check your filter see if it is stopped up if they is not enough air flow it will freeze up it may be low of freon are it could be the defrost board they are several things it could be. Be careful who you call because some of the service people I do not trust you can call CC D***son and ask them who they recommend Earl is a good one but I cannot remember his last name I believe his Bowlen

All good suggestions, thanx I will follow-up with the serviceman on these ideas!

In the heat mode, hot freon should be flowing through the inside unit. If frosting is occurring, the unit must be sending cold freon through. The air coming out of the ducts may not feel cold since this is causing the supplemental strip heat to activate. The four way reversing valve may be malfunctioning.

i am only offering this suggestion as i have experienced it myself. it might not be the answer.

by any chance have you installed a new thermostat in your house? was is specific for a heat pump system?

there is a reversing valve on heat pump systems. if the thermostat or the reversing valve on your system is not working properly you will have this kind of problem.

Not enough air flow and it is having to work too hard.

call your installer of the Heat Pump and let them have another look at it do not let it go too long,,,it could be as simple as a replacing a Capacitor but have them look at it again...

Can anyone tell me why my heat pump keeps frosting up on the inside on these cold mornings? Is this normal? When this happens it just keeps runnning and running! $$$$ This happened last winter too and it was "serviced" !
