If you have a large space or multiple rooms that you want to cool at once, a central air conditioner is your best choice. The central air conditioning system is also called a ducted system as it has a split system that circulates cold air with the help of the duct system installed inside your home. This system has two main units in which the outdoor unit includes the compressor and condenser, while the indoor unit has air handler and evaporator coils. This air conditioner can also be used as an HVAC system by combining it with a natural gas furnace or a set of heating coils inside your home. 


  1. It cools the entire house at once and provides a regulated cool environment inside your house in the minimum time. 
  2. Similar cooling in the entire house at the same time reduces humidity that creates an overall comfortable environment. 


  1. It consumes more energy which leads to higher energy bills. 
  2. Any issue with ducts affects the effectiveness and efficiency of your system.
  3. The exposed outdoor unit susceptible to blockage and damage creating problems with the condenser unit

Ductless Mini Split Air Conditioner

The ductless mini-split air conditioners are best suited for houses that don’t have any duct system. In the case of these air conditioners, one unit is installed in each room, just like window air conditioners. These air conditioners are also a combination of two main units i.e., an indoor unit and an outdoor unit. Both the units of these air conditioners are mounted on the walls and are connected with tubing that circulates the refrigerant between them. These mini-split air conditioners are more energy-efficient and can be controlled via a remote. You can also convert your mini-split air conditioner into a smart air conditioner by combining it with a smart remote controller and manage your air conditioner from anywhere via your smart devices.

These air conditioners are best for a temporary cooling of an area and also for places where a window or split air conditioner cannot be installed.

It cools or heats the room faster in comparison to any other system because the air is blown directly at your level.

It absorbs the heat from the house during summer and circulates it back into the Earth, while during winter, it extracts the heat from the ground and distributes it inside your home. It is an energy-efficient and sustainable method with a longer lifespan than conventional air conditioners. 


  1. It has a high energy efficiency resulting in lower energy bills.
  2. Longer lifespan in comparison to other heating and cooling systems.

One of these factors is knowing about the different types of air conditioners. It is important to understand which air conditioner is ideal for your home based on its advantages, disadvantages, and features. Besides these, also make sure to go through your house design, required cooling capacity of the air conditioner, price, and energy efficiency of the different air conditioners before making your final decision.
