Around 4 PM yesterday afternoon, I heard a terrible clattering coming from the outdoor unit of our office HVAC. The air exit on top had become blocked with ice and the poor compressor fan was trying to beat itself to death. So much heavy snow and slush fell here yesterday....
Set up a kerosene jet heater and proceeded to defrost the unit for the next hour and a half. Good thing it happened when it did...would probably have suffered permanent damage if it had happened after everyone left the building.
@TPD might recognize the heater.....
