About the Friedrich SM21N30
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.

Kuhl is about choice.
When designing Kuhl, their engineers challenged convention to develop the most advanced window air conditioner on the market. Kuhl combines sophisticated controls, unrivalled quality, energy efficiency, and unmatched durability in one sleek performer.

You'll find more options, features and ways to customize your cooling experience than you ever thought possible in a window air conditioning solution.

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.
