Ductless Heat Pump Basics

Ductless Heat Pump (Produces Cooling & Heating)

Today's homeowners are more concerned than ever about maintaining indoor comfort without facing massive energy bills. Ductless heat pumps are viable solutions in many situations. A ductless heat pump system is one that delivers heated and cooled air to individual rooms or small areas in a home. It uses a two-way heat pump to make this happen. Two-way heat pumps are remarkably efficient because they take advantage of heat's natural tendency to move from warm spaces to cool spaces and can reverse the process while using a minimal amount of electricity.

A ductless heat pump system consists of at least one outdoor unit, which houses a compressor and condenser, and at least one indoor air-handling unit. Indoor and outdoor units are connected by suction tubing, refrigerant tubing, a power cable and a condensate drain. No ducts are used at all. Mitsubishi Electric ductless heat pumps are among the most innovative and effective on the market today, and the best systems use them.


Ductless systems have many advantages over traditional HVAC systems. A few prime examples include:

  • Low Operating Costs - Heat pump systems are very energy efficient. The heat pumps themselves require very little electricity to operate. Ductless air conditioners also feature inverter technology that allows compressors to operate at variable speeds. This also makes it easy to maintain a consistent indoor temperature.
  • Easy Installation - Ductless heat pump installation tends to be much simpler than other heating and cooling installations. At the most, a three-inch hole needs to be drilled to make connections between outdoor units and indoor air handlers. Determining the appropriate locations for the indoor units are an important factor. Mitsubishi Electric Contractors are experts at performing these installations.
  • No Ducts - What does ductless mean, exactly? It means precisely what it sounds like: No ducts are required. This is convenient for homes that don't have ducts already. It's also a perk because ductwork tend to leak. In fact, they can reduce the efficiency of a heating and cooling system by as much as 30 percent.
  • Flexibility - At first, people may be concerned about the idea of having indoor air handling units installed in their homes. These units are usually no more than seven inches deep, however, and they can be mounted high up on walls or ceilings.They have sleek profiles and don't detract from existing interior design schemes.
  • Remote Controlled Operation - If a Mitsubishi Electric heat pump has indoor handlers that are installed on ceilings and other hard-to-reach places, how are you supposed to adjust the temperature in a given room? These systems include remote controls. You can make adjustments from wherever you happen to be sitting or standing.
