Ductless Mini-Split AC Systems

Pros & Cons of Ductless Air Conditioning

A ductless mini-split AC system is made up of two main components. There’s an outdoor compressor/condenser and the indoor air-handling fan unit. A ductless air conditioning system always keeps a constant temperature. Mini splits are available in either single-zone units to cool individual rooms or multi-zone units for consistent cooling between rooms.

  • Extremely Efficient
  • No Maintenance Costs
  • Built-In Zoning
  • Easy Installation
  • No Need for Ductwork
  • Less Noise

Some of the notable downsides of ductless mini-split systems include: less filtration capability, the high up-front costs, requires filters to be cleaned regularly, and ductless mini-splits can be an eye sore because of the lines that connect the indoor and outdoor units.

Pros & Cons of Central Air Conditioning

Central air conditioners treat air at a central location and distribute it throughout the house using fans and a series of ducts. After the cold air circulate throughout the house, it warms up and flows back to the central AC via return ducts and registers.

  • Lower Upfront Cost
  • More Efficient for Larger Homes
  • Better Air Quality & Filtration
  • More Options Available
  • Discrete Air Conditioning Unit
  • Consistent Temperature

Some of the notable downsides of central air conditioning compared to ductless AC systems include: higher utility bills, requires duct maintenance, less customizability, noisier than its counterpart, and upfront cost can be higher if no ductwork is present.
