Our WallMaster® Through-the-Wall ACs offer the ONLY perfect fit for existing 27" sleeves, including Fedders A and B (requires a baffle kit), but it also has advanced and sustainability features—providing you precise comfort and significant energy cost savings. Unrivaled commercial-grade construction, engineered with QuietMaster® technology, Precision Inverter®, and integrated Wi-Fi control. As part of our commitment to offering sustainable products, the WallMaster line now utilizes A2L-compliant R-32 refrigerant and features inverter compressors, helping you contribute to decarbonization goals while enjoying more energy cost savings. Available in 10,000 - 15,500 Btu/h. in Cooling only and 10,000 Btu/h in Heat Pump models.
Traditional room air conditioners have on/off compressors that result in wild temperature swings, inefficient energy use, and hard stops/starts that may shorten the life of the unit. Friedrich’s Precision Inverter® variable speed compressor adjusts up or down based on need, providing the user precise temperature control, exceptional energy efficiencies, and dependably quiet operation. Additionally, the frequent on/off operation of traditional units puts strain on both the unit and the power grid during hot summers. Friedrich Soft-Start™ technology starts the compressor with significantly less strain at start up, saving energy.
Engineered for quiet performance with superior components. As much as 45% quieter than competitor’s products.
Integrated Wi-Fi control from your smartphone and voice command compatible. New intuitive platform. Simplified 7-day programmability. With our advanced grouping program, you can control multiple units to work independently or as a single system. You can even invite other users to manage one or more of your units. Adjust set point, schedule, control multiple units, and more—at home or remotely via the FriedrichLink® app.
WallMaster units mount flush with the exterior wall. Firm grip handles on the chassis allow for easy installation and removal from wall sleeve.
Enjoy peace of mind with a durable, commercial grade design built to perform in the extreme conditions of industrial and commercial applications.
Each WallMaster unit is designed with a rotary compressor to provide quiet, dependable performance. Dense blower insulation blocks outside noise. A premium aluminum exterior grille and impact resistant front cover come standard with each model.
Replace old, inefficient 27” sleeve units with WallMaster—a perfect fit in Fedders A and B (requires a baffle kit). Plus, the unit mounts flush with the exterior wall for a seamless installation.
Units are equipped with a three-speed fan, 24-hour timer, and electronic defrost control. Individually adjustable louvers direct airflow to where it’s needed most. The unit’s Money Saver® setting cycles the fan with the compressor.
WallMaster® offers both electric and heat pump options. Heat Pumps provide energy-efficient heating by extracting heat from the outside air. They can be used for primary heating in moderate climates and as supplemental heating in colder climates. 230-volt models have backup electric heat that will activate when outside temperatures are too cold for efficient heat pump operation. The WallMaster (WHV14B33A) Air Conditioner also functions as a heat pump, heating effectively down to 45 degrees—eliminating the need for a second unit to provide warmth. In addition to all the great features you can expect from WallMaster ACs, heat pump-enabled units offer:
Friedrich’s commitment to environment-friendly cooling is shown in the WallMaster. The unit has eco-friendly R-32 refrigerant and arrives in recyclable packaging.
