PTAC units are self-contained heating and cooling systems commonly found in hotels, assisted living facilities, and small apartments. They are designed to be installed through an exterior wall, requiring no ductwork and very little interior space. Because they are "all-in-one" systems, they are easy to service or replace individually without affecting the rest of the building. You can browse our extensive PTAC collection to find quiet, high-efficiency models from brands like Amana and GE. These units often feature built-in humidity control to keep small rooms comfortable in damp climates. For larger spaces, you might consider our Commercial Packaged Units instead, which offer higher BTU capacities.
