Amana Window Ac Units

Overview

The Goodman WS900E-C is a durable, insulated wall sleeve designed for through-the-wall PTAC (Packaged Terminal Air Conditioner) units. Built from heavy-gauge galvanized steel, this sleeve provides a secure and weather-resistant housing for PTAC installations in residential, commercial, and hospitality environments. The internal insulation reduces noise, minimizes heat transfer, and improves overall system efficiency. This model ships in a collapsed (knock-down) form for easier handling and assembly on-site, making it ideal for new construction or retrofit projects. It ensures a proper seal between indoor and outdoor spaces while supporting long-term performance of the PTAC unit.
