New WallMaster Perfect Fit In 27" Sleeves
Redesigned WallMaster is ideal for replacement of old inefficient units. Fits competitor's 27" sleeves, including Fedders A and B.
Designed Specifically For Thicker Wall Installations
Unlike solid-side thru-the-wall air conditioners, window air conditioners have side vents. Covering an air conditioner's side air vents can restrict air flow, diminish performance and potentially void your warranty so they strongly advise against it. Their solid-side sleeve has no side vents. You can install it through walls up to 15-5/16" deep without compromising performance.
Flexible Options
WallMaster fits perfectly with any 27"W x 16-3/4"H x 16-3/4"D sleeve, including Friedrich's WSD sleeve and Fedders' A sleeve. It also can be installed in Fedders' 19-3/4" B sleeve with the available Baffle Adapter Kit. The unit can be mounted flush with an exterior wall or closer to the interior wall for a slimmer indoor profile. And the optional architectural grille enhances the unit's exterior appearance.
Why Choose Friedrich
As you shop for the perfect room air conditioner, you may encounter some familiar brand names. You've seen them on toasters, refrigerators, microwaves and washing machines.
Not the Friedrich name. Because air conditioners are the sole focus of their company. They don't manufacture light bulbs or televisions. They make air conditioners.
You'll find a range of choices: room, portable, ductless split systems, to name just a few. Their product pages will help you determine which type of air conditioner and installation best meet your needs.
For quality, performance, efficiency, choice and service, Friedrich is the name to know. Before you make this important purchase, find out what makes Friedrich air conditioners different.
Durable, Quiet, Efficient
Friedrich air conditioners are hard-working and hard-wearing. Their commercial-grade products are the first choice for tough environments, from oil rigs to the Kennedy Space Center. Constructed from the highest-quality materials and components, these units are built to exacting standards - yet they are among the quietest and most energy-efficient available.
How to Choose a Room Air Conditioner
Compared to large capacity central units, room air conditioners have several advantages. The initial cost of a room air conditioning unit is significantly lower than the cost of central air. Because room air conditioners are designed for cooling small spaces, operating costs are reduced. And, room air conditioners can provide personalized temperature and humidity controls that central systems cannot.
Calculating Cooling Capacity
Cooling capacity is the critical factor in properly selecting a room air conditioner. Cooling capacity is measured in British Thermal Units (BTUs) and typical models will range in capacity from 5,000 BTUs to 28,500 BTUs.
Choosing an undersized unit will overwork the unit and it will not cool properly. Choosing an oversized unit will cost more to buy and operate and it will not dehumidify properly.
We can help you to calculate capacity. Be prepared to provide specific information on:
- Room Dimensions
- A simple floor plan to show the location of doors and north-facing windows
- The number of people it will serve
- Sources of heat such as lamps, TV and appliances
- An explanation of what's above the intended room
- Your insulation provisions
Cooling Capacity by Room Size
Measure the length and width of the area to be cooled. Multiply the length by the width to determine square footage or square meters. When cooling rooms with uninsulated ceilings, great rooms, or southern or western sun exposures - step up to the next BTU size.
| Room Size | BTU |
|
| Sq. Ft. | Sq. m | |
| 150 | 14 | up to 5,000 |
| 165 | 15 | 5,200 |
| 216 | 20 | 6,000 |
| 350 | 33 | 8,000 |
| 425 | 39 | 9,000 |
| 500 | 46 | 10,000 |
| 640 | 60 | 14,000 |
| 900 | 84 | 15,100 |
| 1,110 | 103 | 18,000 |
| 1,170 | 109 | 18,500 |
| 1,435 | 133 | 22,000 |
| 1,672 | 154 | 25,000 |
| 1,960 | 182 | 28,500 |
