Mitsubishi ElectricAre noisy, drippy window units getting you down? Do you have problems heating and cooling certain spots in your home? Does your home lack the duct work necessary for central heat and air? It sounds like a Mr. Slim® split-ductless heating and cooling system is the solution for you.

Popular for many years in Europe and Asia, split-ductless systems are becoming just as popular in the United States, too. Comprised of a remote outdoor unit and a mounted indoor unit, the two are connected via small refrigerant lines that require only a three-inch opening in the wall.

Mr. Slim units are ideal for year-round comfort in your home. They're perfect for new additions, retrofits, finished basements and sunrooms, in addition to existing rooms of the house. Just ask Norm Abram of The New Yankee Workshop and This Old House. He's used Mr. Slim to cool his workshop for years!

Mr. Slim saves resources by allowing homeowners to heat and cool only the spaces being used, as opposed to central heat and air units that maintain the temperature in the entire house.

Mr. SlimMr. Slim is also much more attractive than its window unit counterparts. After all, who wants to occupy a window with an air conditioner when you could mount it out of site high on the wall?

Mr. Slim provides all of these important benefits:
  • Quiet and efficient operation: Mr. Slim runs at as little as 26 dB(A). This means that you can hold a quiet conversation or sleep without having to worry about the air conditioner interrupting you.
  • Mr. SlimNo ductwork is required: You will not have to tear up walls or add expensive ductwork to basement remodels.
  • Will not take up a window: If you take as much pride in your landscape as you do your home, you will appreciate that you can enjoy your handy work from the inside now that you have gotten your window view back. If you own a window unit then you are also concerned with the security issue of someone taking it out and coming inside your home. Mr. Slim eliminates this concern.
  • Effective zone cooling and heating: True zoning means that you can tailor individual rooms to your personal comfort tastes. Perhaps you prefer it cooler in the bedroom or kitchen. Also if do not use your guest rooms, dining room, or bonus room regularly, why cool them day-in, day-out?
  • Versatility: You can air condition spaces you at first thought impossible because there is no space for ductwork and you don't want a window unit. Both at the home or office, Mr. Slim is flexible enough to work in almost any room environment.
  • Remote controlled operation and timer functions: With Mr. Slim, you can control your comfort from across the room. The M-series comes with a wireless remote controller that gives you control of temperature, fan speed, vane operation and more. Plus a timer function means that you can set Mr. Slim to operate when you need it to. For example, if you know you arrive home from the office around 6:00 PM, you can set Mr. Slim to turn on at 5:00 PM to begin cooling before you get there. This means that you are not cooling or heating your home while you're not there, which saves you money.

How does Mr. Slim® work?

Simple explanation: Mr. Slim is a ductless split air conditioning system. If you are familiar with a central system, you have the basic idea of what a split system is, and outdoor condensing unit and an indoor evaporator unit. The basic difference between the two is that with the central system the evaporator unit is typically found in the attic and has ductwork branched off to the different rooms in your house. With Mr. Slim the evaporator is actually in the room being air-conditioned. The indoor unit has a quiet fan that blows across a cold aluminum coil while in the air conditioning mode. The indoor unit is usually a wall mounted type and this unit is connected directly to the outdoor unit by copper tubing and control and power wiring. In the outdoor unit a compressor cycles refrigerant to and from the indoor and outdoor unit and the room air is cooled or heated based on the direction the refrigerant flows between the two.

More detailed explanation: Mr. Slim works like any basic air conditioning system in that the mechanical components employed and the physical process of evaporation occurs. Mr. Slim is a ductless split design that simply means the indoor unit is separated from the outdoor unit and is connected by a gas and a liquid refrigerant line. The outdoor unit is considered the "hot-side" during the air conditioning process. The "cold-side" unit is located indoors. In the heating process the compressor reverses this operation and the heat energy is evaporated in the outdoor unit and the indoor unit collects this heat energy while a fan blows over the indoor coil and distributes the warm air into the room.

How reliable is Mr. Slim?

Mr. SlimMitsubishi Electric designed Mr. Slim to be one of the most reliable air conditioners available. Because every major component is designed and manufactured by Mitsubishi Electric, the system operates optimally to give years of worry-free performance. In the United States we only deal with about ½ of 1 percent failure rate. The a/c industry averages around 4 percent. The reason for this can be explained by the fact that most other a/c products on the market are manufactured with components and parts from an assortment of manufacturers. This can also affect the product's reliability and longevity.

How efficient is Mr. Slim?

With Mr. Slim, efficiency can be measured by the following ways: its rated energy efficiency and the zone conditioning proposition.

Rated Efficiency: Mr.Slim models are all tested and rated against Air Conditioning Institute's (ARI) guidelines for unitary air conditioners and meet the minimum Seasonal Energy Efficiency Ratio (S.E.E.R.) of 10.0 as set by the Department of Energy. Mr. Slim models are available in 10 to 13 true S.E.E.R. When comparing S.E.E.R. there is one key factor to consider. Because Mr. Slim's indoor unit is in the space being conditioned there is no duct-loss as with central systems. Duct-loss means that energy is lost as air is forced through ductwork. Though there is not currently an agency that measures this loss, it is commonly agreed to be around 20%. Mr. Slim INVERTER models operate at very energy efficient levels due to the variable speed operation of the compressor in the outdoor unit. These models run between 11 and 13 S.E.E.R.

Zone Conditioning: Zoning is a more efficient way to air-condition a home. True zoning means that you can tailor individual rooms to your personal comfort tastes. Perhaps you prefer it cooler in the bedroom or kitchen. Also if do not use your guest rooms, dining room, or bonus room regularly, why cool them day-in, day-out? By not conditioning these rooms all the time you save money.
