What’s A Wall-Mounted Ductless Ac Conditioner?

A wall-mounted ductless air conditioner, also known as a mini split system or Mini Split System, is an efficient and convenient way to get refrigerated heat without having to add ductwork to a house or business that needs air conditioning. Wall mounted air conditioning is ideal for homes without a duct system or those that weren’t designed for air conditioning.


Mini-splits are ductless systems that consist of two separate parts, an indoor unit, and an outdoor condenser. The indoor unit consists of a fan, evaporator coil, blower motor, and fan. Mounted on the wall, it measures approximately 3 feet in length, 10 inches high, and 10 inches deep. The majority of systems allow 4 indoor units to be connected to one outdoor unit. This means that you can cool four rooms or zones using one outdoor unit. The outdoor unit, also known as a condensing or condensing unit, consists of a fan, compressor, and condenser coil. The size of this unit will vary depending on how much cooling is required and whether there are multiple indoor units. However, it should not exceed 45 inches in height and 36 inches in width. You may need several indoor and outdoor units depending on the cooling requirements of your home or business.


This ductless mini-split air conditioner has a great advantage in terms of zoning. Each indoor unit is equipped with a digital thermostat that can operate independently of the others. You can cool only the rooms that you use, and not your entire house. This saves you money on energy.

There’s a good possibility that you’ve seen wall-mounted air conditioners in a commercial or residential setting.

Although it might seem strange at first, you will soon be able to understand the workings of these units.

Wall-mounted air conditioners are part of what’s known as a mini-split AC or ductless AC.

These systems are not like conventional central air. Instead of cold air being delivered via ductwork to rooms, they use a different approach. Each zone or room is supplied with air through a wall-mounted unit that is connected to a condenser.

First, it is important to understand the three main components of a wall-mounted air conditioner.

Wall Mounted Units

This indoor unit is responsible for providing cold air to a space or area. This is done by taking in warm air and absorbing heat. Then they deliver cold air.

The cold air is delivered and the unit disperses the heat and moisture through a conduit.

You will need a wall-mounted unit in every room or zone that you wish to cool. The size of your room and the power supply of the system will determine how many you need.


This is essential because your wall-mounted units will not be able to effectively move heat and moisture from your home to the outside.

Outside Unit

This is also known as a condenser. It is an outside unit that receives moisture and warm air through the conduit that runs to the indoor units.

The outdoor unit can efficiently absorb and disperse moisture and hot air when it is working correctly.


The answer is generally yes. The ductless system is much simpler to install than central air.

Two primary questions must be answered:

You will need to place the condenser in a location outside of your home.

You will need to install the wall-mounted units.

It’s easier to answer the first question because you can put it anywhere in your home. It will likely work as long as there is enough space for it to breathe.

This second question requires a little more planning. It is important to consider where wall-mounted units will be installed, keeping both aesthetics and functionality in mind.

You should place your units at least six feet above the floor without any obstructions, such as tall plants or furniture. You should also consider where the units can be placed so that they are not in your way, such as the above doors.
