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 now offers replacement air conditioners and heat pumps that are interchangeable with units no longer available from the original manufacturer. Our units are engineered to fit perfectly within the existing wall sleeve, thereby reducing installation time and expense. They are manufactured on Long Island New York.

We distribute over thirty-five models which replace over forty-five different models available from OEM suppliers such as: American Air Filter, American Standard, Carrier, Friederich, Lennox, McQuay, Nesbitt, Remington, Singer, Zoneaire, and others. Our EZ Cross-Reference guide makes finding the correct replacement unit convenient and simple.

If the replacement unit you need is not conveniently listed, please contact our sales department at: (800) 891-4729 or email us. We offer the complete engineering capability to design any unit to perfectly fit your existing thru-wall dimensions, incorporating increased energy efficiency ratings. All products have a 12 month parts and labor warranty, with extended coverage available for up to a maximum of 10 years.
