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.

Islandaire, Inc. 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 at our modern 48,000 square foot plant on Long Island in New York.

	Each unit features:
	* Commercial duty construction for a longer life.
	* All of our products are manufactured in the USA.
	* High-tech rifled and enhanced refrigeration coils to provide superior heat transfer, which translates into a higher Energy Efficiency Ratio (EER)

The thirty-five models featured in this catalog effectively 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.
