Different Types of Air Conditioning

If you’re searching for some helpful information about different types of air conditioning systems, you’ve come to the right place. To set the record straight, we don’t believe in an air conditioning option being universally “better” or “worse”. However, it is important to understand which option would be better suited for your home and your unique needs.

Our team of HVAC experts will discuss the differences, as well as the pros and cons of both ductless air conditioning and central air conditioning systems. We hope that by the end of reading through our air conditioning comparison guide you’ll have a better understanding of which AC system might be right for you.



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.
