Mini Splits vs. Central Air Summary Table

Understanding Air Conditioning Technologies

When it comes to air conditioning, there are two main types of systems: ductless mini-split systems and central air conditioning systems.

Both systems operate differently, and it's important to understand the differences in order to choose the best system for your needs.

How Ductless Mini Split Systems Work

Ductless mini-split systems are also known as heat pumps. They work by using refrigerant to absorb heat from the air inside your home and transfer it outside.

This process cools the air inside your home. In the winter, the system can be reversed to extract heat from the outside air and bring it inside to warm your home.

Ductless mini-split systems consist of two main components: an indoor unit and an outdoor unit.

The indoor unit is mounted on the wall and contains the evaporator coil and a fan. The outdoor unit contains the compressor and the condenser coil. The two units are connected by a conduit that contains the refrigerant lines, power cable, and drain line.

One of the advantages of ductless mini-split systems is that they don't require ductwork. This makes them ideal for homes that don't have existing ductwork or where adding ductwork would be difficult or expensive.

Ductless mini-split systems are also highly energy efficient, as they don't suffer from the energy losses associated with ductwork.

How Central Air Conditioning Systems Work

Central air conditioning systems work by using ductwork to distribute cool air throughout your home.

The system consists of an outdoor unit, which contains the compressor and the condenser coil, and an indoor unit, which contains the air handler and the evaporator coil.

The compressor in the outdoor unit circulates refrigerant through the system, absorbing heat from the air inside your home and transferring it outside.

The cool refrigerant then flows back inside to the evaporator coil, where it absorbs more heat and cools the air. The air handler then distributes the cool air through the ductwork and into your home.

Central air conditioning systems require ductwork, which can be a disadvantage if your home doesn't have existing ductwork or if the ductwork is old and leaky. However, central air conditioning systems are often more effective at cooling large homes, as they can distribute cool air more evenly throughout the home.
