PTAC, Thru-the-Wall & Window Air Conditioners

Room air conditioners are specifically designed for smaller spaces such as Motel-Hotel rooms, 4-Season Rooms, and Small Apartments.  For our commercial customers, they come in three (3) categories; Package Terminal Air Conditioner (PTAC), Through-the-Wall, built-in (TTW) and Window Mount.


PTAC - This is usually considered the top-of-the-line in room air conditioners,  By design they are quieter, programmable, contain many features, offer different heat sources, allow for different voltages and utilize an industry standard wall sleeve (42”W x 16”H).  Though most commonly found in hotels and motels, they have also become the heating and cooling source for Sunrooms/Four Season Rooms.

In 2010, all models became digital controlled.  Some brands offer a retrofit from manual to digital controls.  The heat/cool range of a PTAC is 7,000 BTU to 15,000 BTU.  Allied offers AMANA, Frigidaire and General Electric branded.PTAC’s.  Call ALLIED and speak to one of our Product Specialist for the model which best fits your needs. 800-991-8480

 TTW – Through-the-wall air conditioners are generally designed to fit wall sleeves 26”W x 15 5/8”H.  TTW units come in a wide range of models from cool only to heat/cool; 115 Volt to 230/208 volt; and an output of 8000 BTU to 14,000 BTU.  All models produced today are digital controlled and often come with remote control (not required for use).  TTW units differ from Window mount units by the fact their air intake and exhaust are through the back of the unit.  A TTW should not be replaced with a window unit.  Allied offers AMANA, Frigidaire, General Electric and LG brands.

Window Mount – Window mount means mounted in a window.  Due to air flow design, these units will not work long if installed in a wall sleeve.  Window mount units come in no standard size and can vary from year to year.  They are available in heat/cool, heat pump/cool or cool only models.  Output can range from 5,000 BTU to 24,000 BTU.  Voltage requirements are 115V or 230/208V depending on models.  Allied offers Frigidaire, AMANA, General Electric and LG brands.
