Xfinity generally charges installation fees for new services, which can vary depending on the type of service and the specific installation required. For instance, if a professional technician is needed to set up services at your home, there may be a one-time fee associated with that visit. Alternatively, Xfinity offers self-installation kits for many services, which could help customers avoid installation fees altogether if they choose to set everything up themselves. It is important to check the current practices and available promotions through the Xfinity website or your account, as these details can change over time. The website may also provide specific information regarding installation fees, potential promotions, or waivers that are applicable.
