How Ductless Heating Works

Ductless heating systems are a type of heat pump. Unlike a standard heat pump, which consists of a single indoor and outdoor unit, a ductless heating system has an outdoor unit that connects with multiple air handlers located in the interior of the property.

These air handlers are strategically mounted on the walls of each room. The handlers include a blower and a coil that sends warm air straight into the space. True to its namesake, there are no ducts required for this heating system and the units themselves are discreet.

Ductless Heat Pumps vs Baseboard Heaters

When debating whether a baseboard heater is right for your home, it’s important to note that the quality of baseboard heaters varies widely. Most baseboard heater models are noisy and provide poor and inconsistent temperature control. They get hot to the touch, which can be dangerous for children and pets.

The two types of baseboard heaters, hot water and electric, are also less efficient than most ductless heating pumps. Although baseboard heating offers temperature control via room thermostats, often it is not possible to deliver a precise temperature to every room. The end result is uneven heating, meaning that smaller rooms are often warmer than larger rooms in the same building.

Ductless Heat Pumps vs Central Heating

Indoor air pollutants can build up inside of the ductwork of a central heating and cooling system, which can spread dust, dirt, viruses, and bacteria to every room. This is especially detrimental to people with allergies, asthma, and other respiratory problems.

Ductwork requires periodic inspection, which can become costly. Common maintenance tasks, such as sealing leaks, adding insulation and cleaning cause the final bill to add up quickly. On the other hand, ductless systems don’t have these problems and are also much quieter than central heating systems.

Ductless Heat Pumps vs. Oil Heating

Oil furnaces use heating oil, which is a nonrenewable resource and an environmental pollutant. Annual heating costs are often significantly higher for individuals who use oil to heat a home versus a ductless heat pump.

Mitsubishi Ductless Heating Systems

A ductless heating system from Mitsubishi Electric may be the right choice for several reasons:


The advances in the heating performance of these units are unmatched in the industry. Mitsubishi’s available H2i® technology can heat your space effectively, even when temperatures outside are down to -13º F. The Hot Start technology delivers hot air as soon as the unit is powered on with no drafts.

Décor Options

Indoor units may be installed anywhere in the room — on the ceiling, on the walls or on floor. This gives you the freedom to select the option that works best with your space’s décor. Choose from ceiling-recessed, horizontal-ducted, and floor-mounted indoor unit options.

Quiet Operation

Both the indoor and outdoor units are specifically designed to provide quiet operation. With the indoor unit operating as low as 19dB, the operation of your heating system will be quieter than a human whisper.

Wireless Control

Wireless control allows you to control your home’s heating at the touch of a button. In addition, select M-Series indoor units are also capable of sensing troublesome regions to regulate ambient temperatures more closely.

Ductless Heating Maintenance

Like any HVAC heating system, ductless heating units require proper maintenance; schedule it before the season begins. In fact, we recommend that you have your system reviewed by a technician once in the spring and again in the fall, before colder weather sets in.

Ductless heating systems do require cleaning. A technician will remove and clean any indoor air quality components, build up from the condensate drain and the evaporator coil, and more. These tasks ensure that your system works more efficiently, helping you to pay less on your monthly bills.

Maintenance also ensures that your system operates efficiently for longer. You will also save money by avoiding repairs that result from improper or poor maintenance of your system.
