What are Mini-Split Air Conditioners?
Mini-split systems are ductless heating and cooling systems. There is no duct system to deliver the conditioned air to the whole residence. Instead, they can heat or cool a single room. So there is more advanced temperature control with increased comfort and energy efficiency. Ductless systems can also offer better air quality as there is no chance of dust and mold growth in the duct as is in the case of ducted systems.
Mini-split air conditioners consist of two separate units: an indoor unit and an outdoor unit. The outdoor unit includes the components like compressor and condenser fans. It is the air handling unit in the indoor unit which is responsible for introducing cool air into the room.
