Central Air Conditioning Systems

Central air conditioning systems are among the most common types of AC systems installed in homes. These systems consist of an outdoor unit (compressor/condenser) and an indoor unit (air handler), connected via refrigerant lies. Air is cooled as it passes over the evaporator coil located inside the air handler and then circulates throughout the home via a network of ducts.


  • Provides consistent, even cooling throughout your home.
  • Can often be integrated with an existing furnace or heating system.
  • Offers the ability to use programmable thermostats for energy-efficient operation.


  • Requires a pre-existing or newly installed duct system, making it less suitable for some older or architecturally unique homes.
  • Can be more expensive to install and operate compared to some alternative options.

Ductless Mini-Split Systems

As previously discussed, ductless mini-splits consist of an outdoor compressor/condenser unit and indoor air-handling units that provide cooling directly to specific zones. They operate without the need for ducts and are a flexible, energy-efficient option.


  • Ideal for homes with limited space or lacking an existing duct system.
  • Offers zoned temperature control for customized comfort.
  • Potential for energy savings by eliminating ductwork, which can lead to energy loss.
  • Quieter operation compared to other AC systems.


  • Typically more expensive upfront than window units.
  • May require multiple indoor units to effectively cool larger homes.

Window and Wall-Mounted Units

Window and wall-mounted AC units are cost-effective options that can provide cooling for a single room or a small living space. They are self-contained and installed either by mounting the unit in a window or through an opening in an exterior wall.


  • Easy to install with lower upfront costs.
  • Suitable for cooling a single room or small space without disrupting the entire home’s HVAC system.
  • Can be removed and reinstalled if you move homes.
  • Energy-efficient for targeted cooling if used correctly.


  • Limited in terms of the area they can effectively cool.
  • Not as aesthetically pleasing as other options.
  • Reduced energy efficiency if used to cool multiple rooms or spaces.

Portable Air Conditioners

Portable air conditioners are freestanding units that can be easily moved from room to room as needed. They typically require a window or venting opening to expel hot air outside.


  • Flexibility of location and ease of movement.
  • Convenient for supplemental cooling or in homes without a suitable central AC option.
  • Can be used on an as-needed basis, helping reduce energy consumption.


  • May not provide sufficient cooling for larger rooms or spaces.
  • Can be noisy during operation.
  • Less energy-efficient compared to central air or ductless systems.

Factors to Consider When Choosing an AC System

  1. Size of Your Home: Determine the size of your home and the amount of cooling needed. Larger homes may benefit from central air or multiple ductless mini-split units, while smaller homes or room-specific cooling can be achieved with window, wall-mounted, or portable units.
  2. Duct System: If your home has an existing duct system, a central air conditioning system may be more feasible for seamless integration. On the other hand, if you lack ductwork or have limited space, a ductless mini-split system would be a more suitable option.
  3. Noise Level: Consider noise levels when choosing the right AC system for your home. Many people find the quiet operation of ductless mini-splits more appealing in comparison to window or portable units, which can be relatively noisy.
  4. Aesthetics and Space Constraints: Keep in mind the visual impact and space requirements of different AC options. Central air conditioners and ductless mini-splits are often viewed as more visually appealing and space-efficient than window or wall-mounted units. Additionally, planning the placement of units within a room can impact the overall design and layout of your home.
  5. Energy Efficiency and Operating Costs: The efficiency of your chosen AC system will influence both the environmental impact and the cost for operation. High-efficiency model, like ductless mini-splits, central air conditioners with a high SEER rating, or correctly sized window units, can result in long-term energy savings and lower utility bills.
