Mitsubishi Electric Ductless Heating


For year-round comfort and energy efficiency, heat pumps might be a very great choice for your house. Modern heat pumps, particularly variable speed mini-split heat pumps, are dependable and environmentally friendly, delivering high-performance heating and cooling to houses anywhere, including in bitterly cold areas.

For homes with "non-ducted" heating systems including radiant panels, and space heaters, ductless mini-split heat pumps (mini-splits) are a good substitute upgrade. They can also be an excellent option for new homes that are extremely energy-efficient and just need a modest space conditioning system, as well as for room extensions when extending or building distribution ducting is not practical.

Low ambient mini splits have a particular construction that allows them to function at very low temperatures. There are many that can operate at maximum efficiency down to 0°F and at reduced efficiency into the minus. Since they don't require any additional heat, they can operate in many frigid climates for a large portion of the year.

If you want to keep your house comfortable and your entire family happy throughout the year, you can’t go wrong with Mitsubishi Electric. Hire an installer who is knowledgeable about the product and its installation and be sure to select an ENERGY STAR® certified unit.

Ductless "mini-split" heat pumps are made to function well in cold climates. But how do they function and why are they so popular with contemporary homeowners?

Ductless mini-split heat pumps: How Do They Operate?

Ductless mini-split heat pumps, also known as “mini splits” and “zoned HVAC,” are a type of heating and cooling system that are ductless. Mini splits and zoned HVAC are other names for ductless mini-split heat pumps, a form of heating and cooling system that doesn't require ducts to condition the air.

The mode of operation of a ductless mini-split heat pump is similar to a refrigerator in your home or a window air conditioner that is set to reverse. They are a very efficient type of electric heating. Instead of using electricity to heat the air molecules, they transport the heat that is already present in the outside air inside your house. Even at extremely low temperatures, this is feasible. Heat pump systems are receiving a lot of positive publicity these days, and for good reason—they're a flexible and effective year-round solution for controlling the temperature in your home.

Heat exchanger coils are used in ductless heat pump systems to transfer warm air from one location to another. For instance, in the winter, your heat pump pulls warm air from the outside to raise the temperature inside; in the summer, it does the opposite, sending warm air outside.

The best option for home additions and renovations without existing ducting may therefore be ductless units. Ductless units may be the best choice when extending or building new duct systems is too difficult or impractical.

Ductless mini-splits' versatility and convenience may also be preferred by larger homeowners who desire more control over their heating and cooling systems. Ductless mini-splits offer versatility and convenience that may appeal to larger houses who desire more control over their heating and cooling systems. You can conserve a significant amount of energy and money by just heating and cooling the rooms that are actually occupied. Additionally, with more control over the temperature, there will be more precision on the thermostat regulation in the home.

What exactly allows a ductless heat pump to do its job so well?

The inside air handling unit and the external compressor/condenser are the two primary components of a ductless mini-split system.

The interior unit, which is often installed high on a wall or suspended from the ceiling, provides conditioned air right into the living area. Instead of using a convoluted duct system, a refrigerant line connects the indoor unit to an outdoor compressor directly.

A power cable, suction tubing, and a condensate drain line are used to link the indoor unit to the outdoor unit in addition to refrigerant tubing.

The one outside unit is typically connected to several indoor air handling systems. While each of the numerous inside units has individual control, they all rely on the same exterior heat pump unit to either absorb or disperse heat.

In contrast, a conventional central air system routes air from the interior air handling unit through a convoluted network of ducts before it enters your room.

The outdoor heat pump transfers heat energy from the ambient air to the inside unit using refrigerant to produce heat. When the refrigerant reaches the indoor coil, its temperature has greatly risen due to compression. Warm air is circulated around the room by a fan blowing air over the heated coil. With no emissions, this heating method is far more environmentally friendly and better for the earth than using fossil fuels. The process is reversed during air conditioning; the indoor evaporator unit absorbs and transfers the heat energy from the room to the outdoor unit compressor. Back at the indoor unit coil, the vapor condenses into a cool liquid and cools. To provide cool air, the fan blows across the cold coil.

The external heat pump uses the refrigerant to transmit heat energy from the outside air to the interior unit, where it is converted into heat. When the refrigerant reaches the indoor coil, it has been greatly compressed, raising its temperature. To provide warm air to the space, a fan blows air over the heated coil. Using this kind of heating produces no emissions and is significantly more environmentally friendly than using fossil fuels. When cooling a room, the process is reversed; the indoor evaporator unit absorbs and transfers heat energy from the room to the outdoor unit compressor. The vapor cools and condenses back into a cold liquid, which returns to the indoor coil of the unit. Cool air is produced by the fan as it blows across the cold coil.

For many households, the mini-split heat pumps from Mitsubishi Electric are the heating and cooling system of choice due to their effective operation and individualize


Mini-splits have several benefits, but their main benefits are their compact size and flexibility in zoning or heating and cooling certain rooms. In some types, there can be up to four indoor air-handling units coupled to one external unit (for four zones or rooms). Depending on how much heating or cooling is needed for the building as a whole or for each zone, the amount will vary. How well the structure is air sealed and insulated may have an impact on this. With individual thermostats for each zone, you just need to condition occupied areas, which can save energy and money.

It is simpler to install ductless mini-split systems than certain other kinds of space cooling equipment. For instance, only a three-inch conduit hole needs to be made in a wall for the connection between the outside and inside units. For this kind of system, the majority of manufacturers offer a selection of connection conduit lengths, and you can, if necessary, place the outdoor unit up to 50 feet away from the interior evaporator. With the compressor placed outside the structure in a more advantageous or discrete location, it is possible to condition rooms on the front side of a house.

Mini-splits don't have ducts, so they don't experience the energy losses connected to ductwork in central forced air systems. Particularly if the ducts are in an unconditioned area like an attic, duct losses can be responsible for more than 30% of the energy used for space conditioning.

Mini-splits provide greater interior design versatility when compared to other add-on systems. The interior air handlers can be hung on a wall, flush mounted into a drop ceiling, or suspended from a ceiling. There are various models that are floor-standing. The majority of indoor units have high-tech-looking jackets that are sleek and around seven inches deep. When the system is hanging from the ceiling or mounted high on a wall, many additionally provide a remote control to make switching it on and off easier.

What makes Mitsubishi Electric different?


The mini-split heat pump systems from Mitsubishi Electric utilize compressor technology that is driven by an INVERTER to deliver precise, on-demand heating and cooling.

The compressor, which is powered by an INVERTER, is the system's heart. The INVERTER compressor continuously operates in the background, altering speeds and capacity as necessary to reach the point temperature of a zone, much like how your heart beats constantly but automatically beats faster when you exercise (or specified area). By only using the precise amount of energy needed to maximize comfort, this way of operation decreases power usage.

Contrarily, many traditional central systems have a fixed-speed compressor that is either entirely off or fully on. This can result in significant temperature changes and energy wastage, which eventually affects the overall comfort of your home and electricity expenses.


Modern heat pumps can keep your family cozy even in cold areas and help maintain the value of your house. Do not worry if you reside in a location with exceptionally chilly weather. Mitsubishi Electric offers heat pump systems with Hyper-Heating INVERTER® (H2i®) technology, which can operate without additional heat down to -13° F and give up to 100% of heating capacity at 5° F. Certain units with H2i plusTM technology from Mitsubishi Electric can provide up to 100% heating capacity at -5° F. High-performance heat pumps from Mitsubishi Electric are an effective and ecologically friendly method to keep your family warm all year round, unlike conventional heating systems that rely on fossil fuel burning furnaces and boilers to produce heating.


Utility savings are one of the key advantages of heat pump systems. Heat pumps can reduce your home's total cost of ownership and monthly utility costs by operating their compressors with energy-efficient INVERTER-driven technology.

The advantages of using an all-electric heat pump system are also acknowledged by utility providers. If a homeowner decides to stop using fossil fuels, they are ready to reward them.

Despite the fact that heat pumps have been around for decades, modern all-electric high-performance models offer improved home comfort, exceptional energy savings, and environmental responsibility.

Mini-splits are incredibly effective at improving the comfort of your house while using very little energy and emitting no pollution. They are also incredibly dependable. They're fantastic for remodeling certain rooms or creating a new home because you have the choice of single-zone or multi-zone alternatives.

Why Choose Mitsubishi?

If you're still not convinced about choosing Mitsubishi Electric heating, consider the fact that their temperature control division was established more than 30 years ago. Mitsubishi has always been in the forefront in the US market because to its wide array of goods.

Mitsubishi is the service to use if you want someone who understands quality, dependability, and attention to their work. The Mitsubishi name on the appliance will provide you with high-quality, long-lasting comfort in your home, regardless of the model or system you choose. You get benefits from their mini-split system that aren't present in the majority of conventional cooling and heating systems.

Mitsubishi is regarded as a pioneer in mini split cooling and heating. Within this brand, some units have electric belt heating that provides faster heat at startup and increases the system performance in freezing climates. Moreover, systems automatically restart after a loss when the power returns.

Getting A Reliable Contractor

Proper system sizing and installation are crucial to maximizing the benefits of a ductless system. Although a do-it-yourself technique is conceivable, but it will most certainly violate the warranty. If the system is the wrong size, the wall penetration is not properly sealed, or the sensitive electronics are mishandled, ductless will never work properly. You must also be competent to handle refrigerants in accordance with EPA regulations.  So It's worth the extra money to have a pro or an A+ licensed contractor perform the job for you.
