Thru-wall air conditioners were developed in the late 1950's. Over the next forty years many companies engineered, manufactured and installed a variety of different units throughout the United States and Canada. Today, a number of these companies are no longer in business or have discontinued their line of thru-wall air conditioners and no longer carry replacement parts.

RoomAire offers EZ Series replacement air conditioners and heat pumps that are interchangeable with units no longer available from the original manufacturer. These units are engineered to fit perfectly within the existing wall sleeve, thereby reducing installation time and expense. These units normally take anywhere from 4-8 weeks to ship so please consider the lead time needed when placing your order. If you have an older PTAC and do not see the replacement unit on our website please contact us. Most likely we have a replacement available. **Please be sure to include your existing model number when placing your order so that we can cross reference it with the exact replacement PTAC for the perfect fit**
