Before you make a decision on any air conditioning system, it’s essential to understand some key features of PTAC and mini split systems to ensure your purchase is the best one for your situation.

Packaged terminal air conditioners, better known as PTACs, are air conditioners that are installed through the wall to control the temperature in an individual room. These inexpensive units are commonly seen in hotel rooms, hospital rooms, dorms, and assisted living facilities. Their easy-to-install design also makes them a popular solution for sunrooms. All PTAC units also come with heating capabilities for year-round comfort.

While PTAC units are a great solution for an individual room, they are not ideal for whole-home comfort. As an additional downside, they’re not as efficient or as quiet as other home cooling options.


  • Inexpensive
  • Easy to install
  • Sealed system that requires little maintenance
  • Good single-room solution
  • Easy to replace if ever needed


  • Can be loud
  • Not very energy efficient
  • Not practical for a whole house
  • Requires large hole in the wall

Mini split

A mini split system is an air conditioning system that consists of two facets: an outdoor unit and one or more indoor units. Mini split systems can be used to cool just one singular room or area, as well as entire homes. This makes the mini split a more flexible option, allowing you to cool as few or as many rooms as you want.

Mini split systems are by far the most efficient type of air conditioning system. The downside is that they are more expensive to install, but you’ll likely reap savings in the long run.


  • Quiet
  • Energy efficient
  • Many options for multi-room
  • Stylish choices
  • Requires only small hole for line set to pass through


  • Can be expensive to install
  • Require professional installation
  • Require separate outdoor unit

PTAC vs Mini Split: Which One is Better?

There is no one-size-fits-all solution for every home. Whether you decide to go with a PTAC unit or a mini split system depends on your specific needs. If you’re aiming to cool an entire home, a multi zone mini split system is your best bet. However, if you’re shooting for cooling a singular room, you can go with either a single zone mini split or a PTAC. It really boils down to your own personal preference and needs.
