My electric heat pump is icing over
something fierce, and the technicians don't really have a clue what's going on. There is one theory I'd like you to comment on, and if it makes no sense, I'd appreciate alternate theories.

Background: this has been going on for a few years, where the outside of the unit ices up and just won't defrost. Currently there's about an inch of ice, which built up overnight. I've had different companies out several times, and it never seems to get resolved. Last week they replaced the defrost board and sensor, which clearly didn't solve the problem.
The guy last week proposed that maybe it's actually due to my gutters overflowing onto the unit when it rains. This is because last week when I called him out we had just had a lot of rain. While there is some detritus in the gutters, the pattern of freezing up doesn't make sense to me. Why would it have that pattern that you can see in the photo? Why wouldn't the other parts of the casing be covered with ice? Also, it was freezing rain last night and i went out and it didn't look like anything was overflowing. Yet this morning when I went to check, it had gone from no ice to what you see in the picture.
More info: this only happens when it's below freezing. I live in North Carolina, US.
So: Could it be the gutters leaking like the HVAC guy suggests?
Or: Is it something else? Ideas?
