You do not have to be present unless you would like to be. However, if you have any minors under the age of 18 in the household, an adult over the age of 18 must be present with them for a service technician to be able to perform work. If you have pets, they must be kenneled or in a safe place, both to not disturb them (the pets,) and so that the pets/animals will not be able to approach our service technicians, especially if they are prone to; or have a history of aggression.
