Single- vs. Multi-Zoned Ductless HVAC Systems, New York, New York

Installing a ductless HVAC system in your home offers many benefits, including more efficient functioning and flexibility when it comes to placement. However, you’ll need to decide between a single and multi-zone system when making an upgrade before you can enjoy these improvements. To make your decision easier, learn more about each option below.

How Ductless Systems Work

Conventional heating and cooling systems use ducts to disperse air throughout the home. With a ductless system, indoor and outdoor units work together to heat or cool your home without any air ducts. The indoor air handling component, which is responsible for blowing air into the home, is connected to the outdoor compressor via a refrigerant line. The outdoor unit either extracts or dispenses heat from outside air, depending on whether heating or cooling is needed.

Single-Zoned Ductless Systems

HVAC systemWith a single-zoned system, there's only one indoor and one outdoor unit in use. These setups are ideal when adding a room to your home or renovating an existing space, such as an attic. They're also suitable for smaller homes or studios, where installing a ducted system might be impossible.

Multi-Zoned Ductless Systems

While there's always only one outdoor compressor with ductless systems, there can be numerous indoor units placed throughout the home. Multi-zoned heating and cooling is useful for homes that have two or more floors. Since each indoor air handling unit will have its own controls, they’re also ideal for households with many people living together. This is because temperatures can be set independently, much to everyone’s comfort.
