Types of Air Conditioners

Feb 17th 2016

When you think about air conditioning, you probably imagine the refreshing, cool air that brings instant relief on a hot day. But air conditioning is more than comfort — it's the process of cleaning, cooling, and controlling air quality inside homes, businesses, and vehicles.

Choosing the right air conditioner is essential to keeping your space comfortable and energy-efficient. Here’s everything you need to know about the different types of air conditioners, plus a helpful comparison to guide your decision.

Mini-Split Air Conditioners

Mini-split air conditioners are ductless systems that use two main components: an indoor air handler and an outdoor compressor. They connect via a small conduit housing power cables, refrigerant lines, and a condensate drain. Mini-splits are ideal for homes without existing ductwork or for creating zoned climate control with maximum energy efficiency.

Window Air Conditioners

Window air conditioners are compact, all-in-one systems installed directly into a window or through a wall. They're a popular choice for cooling single rooms and are relatively affordable. When selecting a window unit, consider the cooling capacity, window size, energy efficiency, and maintenance needs.

Central Air Conditioning

Central air conditioning systems cool entire homes through a network of supply and return ducts. Cool air is distributed through vents placed in walls, ceilings, or floors, while warm air is pulled back to the system for re-cooling. Central AC offers consistent, whole-home comfort but requires professional installation and ductwork.

Portable Air Conditioners

Portable air conditioners are mobile, self-contained units that can be moved from room to room. Perfect for renters or supplemental cooling, these units typically include a window vent kit and require minimal setup. Many models come with wheels for easy relocation.


Mini-Split Air Conditioners: Why They’re a Top Choice

  • Flexible Zoning: Mini-splits allow you to cool specific rooms or areas. A single outdoor unit can support multiple indoor units (up to four or more).
  • Energy Efficiency: No ducts mean minimal energy loss, saving up to 30% compared to central systems.
  • Design Versatility: Indoor air handlers can be mounted in ceilings, suspended from ceilings, or hung on walls, offering flexibility for interior design.
  • Easy Installation: Smaller installation footprint compared to ducted systems, with less invasive construction.
  • Whisper-Quiet Operation: Mini-splits are known for being much quieter than traditional central AC units.
