Ductless mini split air conditioners come with two units: indoor units that deliver cooled air into the room, and an outdoor unit that processes and expels warm air from your home. The two units are connected through the copper tubing and refrigerant line, cycling coolant between the two units. The ductless air conditioner is one of the popular types of aircons.
Ductless Mini Split Air Conditioner - Pros and Cons
Ductless air conditioners are sleek and modern, and they fit into almost any residential or commercial space. The term mini split system refers to the cooling system having two units: the indoor unit and the outdoor unit.
Pros: Energy Efficient with High Cooling Power
Most ductless air conditioners on the market now feature Seasonal Energy Efficiency Ratio (SEER) rating, and the best ductless air conditioners should be energy efficient, while still providing ample cooling capacity to chill large spaces, with an average British Thermal Units (BTU) range between 12,000 BTU to 60,000 BTU.
Pros: Uses Minimal Space
The outdoor unit may require more space than the indoor one, but still uses relatively less space than central air conditioner units. The indoor ductless air conditioner uses minimal wall space as it makes use of available space on the wall to mount on.
Pros: Accessible with Easy Maintenance
Maintaining a mini split air conditioning system is relatively simple: clean the filter every two weeks, and give the AC system a wipe down to keep it clean. Most aircon servicing companies can handle a ductless air conditioner, and there are multiple brands and models on the market to choose from.
Cons: Professional Installation
Some air conditioning systems, such as the portable air conditioner and window air conditioners, do not require professional assistance to install. However, mini split systems do, particularly with installing the compressor unit. These cooling systems often come pre-charged with refrigerant, which can only be handled by professional HVAC technicians.
Cons: Requires Drilling into Walls
Another con of ductless air conditioners is that installation requires drilling through the walls to connect the indoor and outdoor units. This setup is not suitable for rented apartment units, or spaces with load-bearing walls. Aesthetically, some homeowners may not want to drill a hole through their walls to install their mini splits.

Ductless Air Conditioner Installation Process
The ductless air conditioner will need professional assistance when it comes to installation. The first half of the installation process, however, can be done DIY:
First, secure the mounting brackets on a non-load bearing wall, ensuring the brackets can withstand the weight of the ductless air conditioner. Your installation kit should include all parts necessary for the brackets.
Next, tie the copper cord, condensate drain line, and refrigerant lines together, and loop these cords through a hole drilled through in the wall. These wires will connect to the outdoor compressor unit. Set up the wire casing to prevent weather and outdoor elements from damaging your wires.
Secure the air conditioner on its mount, and place the compressor unit outdoors, right behind the wall where the indoor AC is mounted. Mount the compressor unit to a sturdy stand by drilling the unit into a platform. A professional technician will then connect the two units.
