An efficient, powerful air conditioning system is the best way to keep your home cool during the sometimes brutal heat of the summer months, and they are far more effective than swamp coolers and other low-cost cooling solutions. However, different types of air conditioning system are available, and choosing the right one for your home can be difficult.
Multi split air conditioning is not as widely used as either conventional split system or ducted air conditioning, but these unique climate control systems have numerous advantages over their more common counterparts. However, multi split systems also have some disadvantages you should be aware of.
Advantages Of Multi Split Air Conditioning
Whole-Home Cooling
Multi split air conditioners work on the same basic principles as ordinary split systems, with an outdoor condenser feeding cold refrigerant liquid to an indoor blower unit. However, the condensers used in multi split systems can supply several indoor units with coolant simultaneously, while a conventional split system can only support one indoor unit.
This allows multi split air conditioners to cool your entire home in the same manner as a ducted air conditioning system. Each indoor unit can also be individually controlled, allowing you to redirect the system's cooling power to different parts of your home as needed.
Compact
The conduits that supply a multi split's indoor units with coolant are much smaller and narrower than the air ducts used by a ducted system and can be installed inside walls and cramped ceiling cavities. This allows them to be used in smaller homes that cannot accommodate a bulky ducting network and also make them less visually obtrusive.
Energy Efficient
Split system air conditioners are highly efficient, and multi split systems even more so. Because they can supply multiple indoor units with coolant using a single condenser, they use less energy than multiple 'single' split systems. A well designed multi split system will cost significantly less to run than both ducted systems and multiple single split systems.
Disadvantages Of Multi Split Air Conditioning
Expensive Installation
Multi split air conditioners are less commonly used than ducted and single split systems and must be carefully designed to ensure that all the indoor units receive adequate amounts of coolant. As a result, they are relatively expensive and time-consuming to install compared to ducted systems and multiple single split systems.
Single Point Of Failure
Split system air conditioners are generally very reliable, but a multi split system will become useless if the single outdoor condenser unit malfunctions, leaving your entire home without cooling. If 24/7 reliability is important to you, it may be worth investing in multiple single split systems. If one condenser fails, the others will continue to function, keeping most of your home cool.
