Single Zone vs Multi Zone Difference | Ductless Mini Split Heat Pump

Mini split heat pumps are one of the most energy efficient heating systems in the world. Also known as ductless heat pumps, mini splits come in single zone and multi zone units. Single zone mini split systems are great when focusing on one common area such as a single room or garage. Multi zone mini split systems are more commonly used when focusing on your entire residence. But which ductless option is best for you? Lets find out.

Two Options

Ductless heat pumps are the most trending heating systems in the Northwest and for good reason. They are highly energy efficient, quiet, require no ductwork and cost much less than traditional heating systems. In addition to heating, ductless mini splits provide air conditioning for individual rooms or zones also known as single zone vs multi zone:

Single Zone Mini Split Operation

Single zone mini split heat pumps consists of an outdoor unit and an indoor unit. It also includes one line set, one cable and one drain line.

Multi Zone Mini Split Operation

Multi zone mini split systems will consist of one outdoor unit, but several indoor units. Unlike a single zone system, a multi zone unit will need more accessories for each indoor unit. Keep in mind that multi zone mini split systems allow you to to regulate the temperature in each room individually maximizing the comfort for everyone living in the home. These ductless systems are more difficult to install than a single zone unit and we recommend contracting a local HVAC company for installation.
