What is a Ductless Mini-Split AC System?


A ductless air conditioner, also known as a mini-split system, has two main components. The first is a cooling unit mounted to an interior wall and the second is a unit located outside the home or business. Refrigerant and electrical lines connect the exterior unit to the indoor wall-mounted cooling units.

The outdoor unit includes an inverter-driven heat pump that cools refrigerant and sends it back inside to an air handler via small lines and a wireless control unit allows you to adjust the temperature, fan speed, and more with the touch of a button.

Ductless HVAC systems offer numerous benefits.

They are easy to install, operate quietly, and offer an attractive design. Ductless systems are reliable, the same system heats and cools, and it is controlled wirelessly. A ductless system is ideal for new additions, renovated spaces, garage, or basement rooms, and they are an effective solution for any property that can't accommodate ductwork.

Indoor units can be installed anywhere in the room - on the ceiling, walls, or even on the floor. Outdoor units come in a wide variety of capacities, they are easy to install, and can be camouflaged, which is especially significant for maintaining the aesthetic of historic homes.

How Does a Ductless System Differ from Central Air Conditioning?

With a ductless system, the amount of cold air that enters a room can be controlled via a wireless remote. This makes it possible to maintain one room or an area of a building at a different temperature from another room or area within the same building.

With a central air conditioning system, cooled air is distributed to every room via a system of ducts. That makes it impossible to control the amount of cool air in one area without changing the temperature of every room in the building.

Additionally, since central air conditioning systems depend on air ducts, they carry with them the risks of poor indoor air quality. While air ducts are good at distributing cool air, they only work when they are in top condition. Damaged air ducts can allow pollutants to enter your system and be distributed through the entire home.

Since ductless air conditioners do not rely on ducts to bring cool air into the home, indoor air stays clean. With a ductless mini-split system, you benefit from little to no fluctuation in temperature and the overall indoor air quality is improved.

Why Choose a Ductless Cooling System Over a Window AC Unit?

A window AC unit must be placed in a window, which means reduced light and the inability to use the window for fresh air. Additionally, the air conditioner must be the proper size to fit the window opening. That means that you'll have to worry about how to fill the remaining space around the air conditioner, which could result in even less visibility to the outdoors, as well as an eyesore.

Installing a window AC unit is also a security risk because there isn't much holding the unit in place. An intruder could easily remove it from the outside in order to gain access to the property. Ductless systems, on the other hand, leave all windows available for use and pose no threats to home security.
