From the Manufacturer

NEW 2014 Ductless Split Systems Line
Friedrich's new J-Series ductless split system line offers 146 installation configurations - of which 102 meet Energy Star published minimums with SEERs up to 25.0 and EERs up to 14.0. The ductless wall-mounted units have several unique, built-in features that make for a simpler, one-person installation. Friedrich's Precision Inverter Technology adjusts outdoor and indoor fan speeds and cooling output, to provide more precise cooling and dehumidification.

Why choose wall-mounted
If you have one or more rooms without exterior walls or windows, a wall-mounted ductless split system will work beautifully. The indoor air handler is sleek, unobtrusive and quiet. You need only a 2" clearance from the ceiling, so you'll have lots of placement options. All systems come with a remote control, so even units high on the wall are easy to operate. There's also an optional wired, wall-mounted controller for models over 18,000 BTU.

Choose from single-zone cooling models, single-zone heat pumps that cool and heat, and multi-zone heat pumps that individually cool and heat multiple rooms.

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.

Warranty Info

Warranties on mini split air conditioners only include parts and do not include labor. The licensed HVAC Technician who installs your air conditioner should always provide you with a labor warranty (preferably for at least a full year to compliment the manufacturers' parts warranty).

AJ Madison recommends the installation of a mini-split system to be performed by a trained and qualified HVAC technician with the proper knowledge and background. A trained technician will be able to judge the best location for the air handling (evaporator) unit and also the correct size for the area the unit will heat and/or cool. For assistance with all your technical needs please contact our technical department at

Should you experience an issue during the installation or the initial startup of a unit please do not contact the manufacturer. You should have the technician that installed your system contact either AJ Madison or the manufacturer. We cannot accept any service or warranty calls from anyone but a licensed HVAC technician.
