CPS Heating and Cooling explains the difference between heat pumps and ductless AC systems.

Many people looking for heating and cooling solutions for their homes ask about ductless mini-split systems and heat pumps. It can become difficult to distinguish between them at times so in this blog we will explain the differences between traditional heat pumps, ductless mini-split heat pumps and ductless air conditioners.

Heat Pumps

Heat pumps move heat from one area to another by extracting heat from the outside air, circulating refrigerant between the outdoor compressor and an indoor air unit, then distributing it throughout your home. During the warmer months, the process is reversed, and heat is sent outside your home, providing you with cool air. They are powered by low levels of electricity and are very energy efficient. Ducted air-source heat pumps utilize the ducts and vents throughout your home.


Ductless Mini-Split Heat Pumps

As the name implies, these systems do not require ductwork to regulate the climate in a room or space. Rather they use one or more indoor air-handlers connected to an outdoor unit (compressor/condenser) that work together to heat or cool the indoor climate. The outside unit extracts heat from the air where it is absorbed by refrigerant and delivers it to the room via the indoor unit. Ductless heat pumps can reverse this process in the summer by absorbing heat in the room or space and the refrigerant in the outside unit releases the heat into the outdoor air.


Ductless Air Conditioners

Like the mini-split heat pumps, ductless air conditioners consist of an outdoor compressor unit and an indoor air handler to regulate the temperature in specific areas. However, rather than pulling air from the outdoors, ductless AC systems recycle the air already in your home. Unlike ductless heat pumps, they only provide cool air, requiring a separate heating system for most New England homes and business owners.

While there are benefits to all systems, we suggest consulting with an experienced HVAC technician to ensure you get the right heating and cooling solutions for your home or space.
