1 of 3 things will happen
#1. They will blow full force for however long they can.
#2. They will blow enough to test the new parts of the system and get all the kinks out for when there are favorable long term temps.
#3. They wont blow at all. They wont waste money and they wont get everyones hopes up too soon if it went back to warmer weather.
But #3 wont happen..... because I said so.
