How does ductless mini split system work?
A ductless mini-split air conditioner works like a regular central air conditioner but without the ducts.
The indoor unit blows warm air from your home over cold evaporator coils. The refrigerant inside these coils absorbs the heat from the air and runs it to the outside unit where the refrigerant then dumps all the heat it pulled from your home’s air.
In a mini-split ductless system, the smaller indoor unit is actually in the room it’s cooling. The indoor unit simply pulls in warm air from the room it’s in and blows cold air right back into the room. This way the need for air ducts is completely eliminated.
So, how can a ductless system cool the entire home?
It’s very simple. Multiple indoor units can connect to a single outdoor unit to provide air conditioning to your entire home.
