Mitsubishi Electric: The Proven Leader in Energy-Efficient Ductless Heating and Cooling

By James K. Kim

When it comes to ductless mini split heat pump systems, Mitsubishi Electric is typically the first brand that comes to mind.

That’s because they are the originator of this cutting-edge heating and cooling technology and the leading global manufacturer known for quality and tremendous value. As a Mitsubishi Electric Diamond Elite Contractor, the Westchester County HVAC pros at Cottam Heating & Air Conditioning are specially qualified to sing the praises of these excellent products.

A Brief History of the Ductless Mini Split

The first ever ductless mini split was installed way back in 1959 in Japan by Mitsubishi Electric. 

They have continued to produce state-of-the-art all-electric high efficiency heating and cooling systems that have revolutionized the world of HVAC with their convenient versatility and compact size. Their equipment offers versatility for multiple applications in a variety of residential and commercial spaces.

Traditionally, most dwellings having central heating and air conditioning systems installed would require multiple noisy, bulky pieces of heating and air conditioning equipment as well as custom fabricated sheet metal ductwork that must be run internally through walls, ceilings, and floors. 

Since most Japanese homes were small, densely packed amongst each other, and featured thin walls, the traditional ducted central HVAC systems were not a feasible option. 

As a result, the ductless mini split wall mounted unit was invented to fill the need for a compact, simple, and ductless option for indoor cooling and heating. 

Fast forward to today, and Mitsubishi Electric is still a leading worldwide manufacturer of both ductless mini splits as well as ducted heat pump systems for both residential and commercial buildings. 

Why choose Mitsubishi Electric for your new ductless mini split system?

There are a multitude of useful benefits for choosing a Mitsubishi Electric ductless mini split system.

Mitsubishi Electric produces a variety of ductless mini splits capable of working in both single zone (i.e. one indoor ductless unit connected to one outdoor heat pump for conditioning one space) and multizone settings, in sizes ranging from 6,000 BTUs to 36,000 BTUs. Most of these systems are Energy Star-certified, as well.

Ease and Versatility of Installation

A ductless mini split system, as its name implies, does not need to have custom ductwork to be fabricated and installed in the floors, walls, and ceilings. 

Instead, a 3” wide opening is typically all that is needed to run refrigerant piping, wiring, and a condensate drainline from the indoor ductless unit to the outside heat pump. 

This means there is no need for opening and repairing any sheetrock opening or other hassles of a traditional ducted split HVAC system.

Because of this easier and more versatile installation, a ductless mini split system can be installed almost anywhere with a much more compact footprint that can fit almost anywhere. 

There are a multitude of configurations and ductless indoor unit types:

• Wall-mounted units installed higher up on a wall a foot or two below the ceiling 
• Recessed ceiling cassettes for an even more subtle and unobtrusive installation in the ceiling
• Floor-mounted units that are installed lower on the wall closer to the floor, perfect for low angled walls or when adequate wall space is not available

Homeowners have so many more options for heating and cooling a variety of spaces throughout the home when they choose to go with Mitsubishi Electric ductless mini split systems.

Whisper-Quiet Operation with Total Zoning Control

Unlike noisier and obtrusive window AC units or packaged terminal air conditioning units (typically found in hotels and urban apartment buildings), and even traditional ducted central systems, Mitsubishi Electric mini split systems indoor units operate at a decibel level of 19-22 dB, which is quieter than a whisper. 

The outdoor heat pump units run at 46 to 58 dB, comparable to a refrigerator or light rain.

Since each Mitsubishi Electric ductless unit is independently operated via remote control or the Mitsubishi Electric Comfort (formerly known as Kumo) mobile app, each space containing an indoor unit can be individually set for heating or cooling as needed by the occupant. 

In other words, if someone in a room with a ductless unit prefers the temperature at a different setting from someone in another part of the home, they have the freedom and capability to adjust the unit’s output accordingly. 

Improved Energy Efficiency for Better Utility Savings

Mitsubishi Electric ductless mini split systems are up to 40% more efficient than traditional ducted heating and cooling systems. Since there is no ductwork, there is no wasted energy from leaks or long duct runs. 

Additionally, Mitsubishi Electric features various lines of ductless equipment that is Energy Star-certified, ensuring smart, efficient, and environmentally friendly products for homeowners to choose. 

And depending on what state you reside in, there may also be potential utility rebates and tax credits available when these systems are installed.

If the Mitsubishi Electric ductless mini split system is used as the home’s primary heating source, then there will be savings from not using fossil fuels, such as natural gas, oil, or propane as the heating source.

Ease of Maintenance 

Mitsubishi Electric ductless units feature re-usable filters that can easily be washed and re-installed quickly and easily by the homeowner. 

It’s also recommended to have the system professionally maintained and serviced at least twice a year (once before air conditioning season and once before heating season) to ensure refrigerant levels are adequate and the system is running as efficiently as possible to ensure maximum operational lifespan. 

Improved Indoor Air Quality 

Mitsubishi Electric ductless mini split systems have built-in advanced multi-stage allergen filtration, ensuring the air you are breathing is cleaner and healthier. 

Running the system allows for airborne contaminants to be removed from the air. As a result, the air is filtered and cleaned while the system is in operation.
