Mini-split and ductless air conditioning systems are often used interchangeably, but there is a slight difference between the two.
A mini-split system is a type of HVAC system that does not use ductwork to distribute air. Instead, it uses a small outdoor unit and one or more indoor units to provide cooling and heating to specific zones in your home. Mini-split systems can be used in a variety of home sizes and styles and are highly efficient.
On the other hand, ductless air conditioning systems are designed specifically for homes without existing ductwork. They use an outdoor unit and one or more indoor units, similar to a mini-split system. However, the indoor units are typically mounted on walls or ceilings and do not require ductwork.
While both mini-split and ductless systems are highly efficient and can be used in a variety of home sizes and styles, ductless systems are specifically designed for homes without existing ductwork, making them a good option for older homes or homes with non-standard layouts.
When deciding between a mini-split and ductless system, it's important to consider your home's needs and existing infrastructure. Consult with a professional HVAC technician to determine the best option for your home.
