I've got the AS plugged into the house current (30 amp) on heat-pump mode with cabinet doors open. I'm concerned that the snow will accumulate to high on the roof to block the access to the ceiling unit. Any advice? We've never de-winterized before until the snow was long gone. Thanks
As the others have said, I'd opt for the furnace unless you are low on propane. One of the dangers is that even though the heat pump has a de-ice function, it can be inadequate if enough ice forms on those outside coils. Here's a picture of my Classic on an October camping trip to Branson. Check out the white which is ice on the coils. There was high humidity outside and when we got back to the trailer, it was about 48 inside since the heat pump couldn't extract any heat from the outside coils due to them being encased in a block of ice.
Also consider either lighting the water heater (assuming it also is full), or if you have a gas/electric unit, turn it on electric. That tank is pretty well insulated, but the vent will expose the tank to the cold.
