in your home. You are trying to decide between a traditional central AC system and a ductless mini-split system. What is the difference and which is better? The answer is that IT DEPENDS. It depends on your home and what you are trying to do.
Central AC System: A central AC system or central air conditioning system will treat the air in one central location and then distributes the air to and from the rooms using one or more fans and a series of ducts. The supply ducts circulates the cooled air out to the rooms and air flows back through a return air system to be cooled again.
Ductless Mini-Split: A ductless mini-split system has two parts. The outdoor compressor unit and an indoor air handler. The two parts are connected with a conduit. No ductwork is required. They can be multi zone (multiple rooms) but there needs to be an indoor air handler placed into each zone (room). Ductless mini-split system indoor units can be concealed making them as aesthetic as a central AC system.
Ductless mini-split systems are highly efficient and are ideal solutions for older homes or buildings that don’t already have ducting. They are excellent solutions when one or two areas are being cooled. Installations can be more expensive on larger multi-room applications.
Central AC systems are great choices when a home is already ducted and can share the ducting with a central heating system. A central AC system is simple to operate from a single thermostat without having to go room to room to control temperature.
Installation: Ductless mini-split systems are usually easier to install.
Operating Cost: Ductless mini-split systems can easily cool only the occupied areas so their cost of operation is often less. Central AC systems will cool the entire house.
Your choice of a ductless mini-split system or central ac system will depend on your situation.
