Worried but don't want to smother him

I've been out of town for two weeks. My husbands home alone in alaska... Today we have church at 9am.  I texted him at 830 to remind him to do something at church. He hasn't answered and won't answer my calls. It's 10 now. He never sleeps in this late.... I'm super worried. I keep imagining him dying in bed and no ones there to help him. Should I send our neighbor/close friend to check on him? I'm not sure what to do.
