What is A Mini Split Air Conditioner?

If you've been looking for an affordable, efficient way to keep your home cool, you've probably come across the term "ductless mini split system" or simply "mini split."

But what is a mini split air conditioner? Like central air conditioners, mini split systems consist of two main parts: an outdoor compressor/condenser and an indoor air-handling unit containing the evaporator coil and fan. A conduit line containing the refrigerant tubing, power cable and other essential lines connects the outdoor and indoor units.

Unlike central systems, however, there's no need for a duct system with registers and return vents to distribute cool air. Instead, cool air flows directly from a slim indoor air handler mounted on a wall, ceiling or floor.

How do mini split air conditioners work? Their operation is similar to that of a central air conditioning system. Refrigerant gas circulates through the outdoor compressor, rising in temperature and pressure. The gas then flows to the outdoor condenser where a fan extracts heat. The refrigerant flows through the refrigerant lines to the evaporator coil in the indoor unit. A fan in this unit pulls in room air over the evaporator coil, cooling the air. The cool air is then blown into the room. A remote control lets you turn the unit on and off and control the temperature.

Mitsubishi Electric ductless systems are ideal for homes without ductwork. You'll enjoy improved comfort without the expense of installing ductwork. They're also useful in large homes because they can be designed to provide precise control over the temperatures in different parts of the home.

The Efficiency Debate: Mini Split vs. Window Unit

The idea of an air handler hanging on your wall may sound a lot like a window or portable air conditioner. In reality, though, ductless mini splits offer advantages window units can't. If you're not sure where you stand in the mini split vs. window unit debate, keep in mind that mini splits can offer you:

  • Lower energy bills -- Mini split systems save money in the long run. Window units are cheaper to purchase and install, but mini splits are more energy efficient. With a mini split, you'll see a return on your investment in the form of lower electric bills.
  • Improved aesthetics -- Mini split indoor units are unobtrusive. Usually around 7 inches deep and mounted high on your wall or on your ceiling, mini split air handlers are hardly noticeable. Window units, on the other hand, block light and obscure your view of the outdoors.
  • Quiet operation -- Some air handlers used with Mitsubishi Electric heat pumps operate with a noise power of just 19dB(A), quieter than a whisper. Window units produce a whir and hum that may interfere with your ability to hear your TV or sleep soundly.

Where to Buy Mini Split Air Conditioners

Mini split air conditioners are among the easiest cooling systems to install, but even so, it's important to work with a professional throughout the purchase and installation process. To reach its full performance potential, a mini split system must be selected for your individual needs, sized precisely and installed correctly.

Mitsubishi Electric offers a number of mini split models in the M series and P series. Each model has specific characteristics that make it ideal for certain situations, but not right for others. Selecting the best system for your home requires in-depth knowledge of Mitsubishi Electric technology.
