You don’t have to be, but you should be. Things can go faster when you are home. If there is a problem with a circuit breaker or getting access to water, it can go much faster if you are available. At a minimum, you should be there when we arrive, get set up and start removing ice. Once these things are going smoothly, it is up to you whether you stay around or not. One benefit of being home is that you can monitor the progress and you can see how hard our technician will work to remove your ice.
