How to Install a Mini Split AC

A Mini Split AC is the ideal cooling system for homes that don’t have ductwork. Its return and supply vents pull warm air from the house and send it to an air handler, where it is filtered and cooled. The system has an outdoor unit called a condenser that provides the indoor coils with refrigerant. Supply and return vents deliver the cooled air to the rest of the house. While central air conditioning is a good choice for homes that have ductwork, the energy efficiency and cost of mini-split HVAC makes this option a more affordable option.

Disadvantages of mini-split AC

Mini split air conditioning is an effective way to move air from one room to another without adding ductwork to your home. Many homes experience uncomfortable air temperature differences between rooms, and mini splits can move cooler air from the basement to the upstairs. Because mini splits do not require ductwork, they are ideal for homes that already have a central air system. However, they do require a professional to install them.

Mini-splits are more cost-effective than centralized systems, and provide greater flexibility and convenience. Properly positioned and professionally installed, mini-splits can offer good value for your initial investment. They also offer a number of customizable features, such as a sleep feature and a timer. These features are not available in conventional heating systems.


Purchasing a mini split AC system can be an expensive undertaking. ThereĀ Mini Split AC are many factors that determine the price. The size of the system is a significant consideration. The most common size is 12,000 BTUs. A mini split AC system can be installed in one room or several. Some brands have five indoor units while others have as few as two.

Installation costs for a basic mini split AC system can range from $2,000 to $8,800. This includes the installation of wires, lines, boxes, and other necessary pieces. In addition, a refrigerant line can cost as much as $5 per foot. However, labor costs only make up a small portion of the overall cost.

Energy efficiency

Mini Split AC systems have a standardized energy efficiency rating that measures the cooling efficiency. The higher the SEER, the more efficient the system is. Both central air conditioners and ductless mini-splits are measured on the SEER scale. These systems also feature Energy Star labels. If you want a system that will provide energy efficiency and comfort, look for a SEER rating of 15 or higher.

Mini Split AC systems have two main parts: the outdoor compressor/condenser and the indoor air handling unit. These units are linked to one another through a conduit that also houses the power cable, refrigerant tubing, suction tubing, and the condensate drain.


There are a few important steps to take in the installation process of a mini split AC system. First, you need to have the necessary electrical wiring in place. A dedicated 110-, 220 or 240-volt circuit should be set up for the unit. If the unit is to be installed in a room, make sure to have a licensed HVAC technician handle the wiring.

The next step is to figure out the size of your system. You can get this information by asking a HVAC contractor. The system’s capacity is measured in British Thermal Units, or BTUs. For instance, one ton of cooling capacity equals 12,000 BTUs.
