What is a ductless mini-split system?

A ductless split system is “split” into two primary locations, with its parts connected through a primary conduit system. A compressor is installed outside of the home, while individual heating and cooling units are installed inside in one room or in multiple rooms.

Ductless and Split System FAQs and Information

The greatest advantage with split systems is the ability to connect multiple units to one compressor, allowing for individual heating and cooling needs.

Due to easily-accessible filters, little to no ductwork to clean, and simple wiring between the indoor and outdoor units, ductless systems require minimal maintenance. Ductless systems are typically carefree so long as the filter is cleaned or changed every few months.

The average home has, typically, 3-5 units installed, each with their own thermostats for precise temperature control in each room. Ductless heat pumps are also able to provide warmth from the start of operation, reducing cold drafts in your home.

If you feel or know your ductless heat pump or mini-split system is not working there are a few steps you can take before calling a certified HVAC technician:

Many ductless systems use a remote controlled thermostat to control the system. Check to make sure that the thermostat has power. Then, confirm the system is not responding by adjusting the temperature directly on the ductless unit. If the unit responds, the thermostat control may be bad, or the batteries may need to be replaced.

Ductless units, though more compact, still use filters, much like their larger cousins. A clogged filter will starve the unit of fresh air and cause the unit to shut-off. Refer to your equipment manual to identify your filter location, and then check to make sure they aren’t clogged or require cleaning or replacement.

The life expectancy of a ductless system, installed to manufacturer specifications, should last a minimum of 15 years, if not longer.

There are certain considerations that must be taken when considering a ductless system installation. Ductless systems are ideal for single room applications, where there are no obstructions preventing air circulation. Ductless systems operate in a line of sight, and are most efficient when there is an unobstructed line of sight to the unit. It is also important to consider how the unit will distribute air, and if additional wall units will be needed to serve other rooms.

In regards to aesthetics, ductless units typically need to be installed on interior walls that have access to the exterior. This is needed for the condensate lines and the refrigerant lines for the unit. If there is access to a basement or crawlspace below the unit, it’s possible to mount a unit without having access to the exterior of the home.

If hanging the unit on a wall is a concern, there are other ductless options. One option is called a cassette, which is mounted directly into the ceiling, as opposed to away. Another option is a floor-mounted unit, which would resemble a modern-looking radiator. This is a great option for older homes, because it helps maintain some of the home’s traditional aesthetics.

If the system is configured for heating only, or cooling only, it should be serviced once a year. If the system is capable of both heating and cooling, it should be serviced twice a year.
