About Ductless Systems
Ductless HVAC systems, also known as mini-split systems, are heating and cooling systems that don’t require ductwork. They can be used in homes, commercial buildings, and other spaces. This can be helpful in older homes that have never had ducts! Green Home can help you choose the best system for the unique needs and size of YOUR home. Call, or text us to arrange a free estimate.

How They Work
- A single outdoor unit, called a condensing unit, connects to one or more indoor units via a refrigerant line
- The indoor units, called air handlers, are mounted on walls or ceilings
- The indoor units circulate cooled or heated air throughout the room
Key Features and Benefits
- Temperature control: Carrier ductless systems can provide precise temperature control for individual rooms
- Energy savings: They can save money on utility bills by only heating and cooling occupied areas
- Improved air quality: Multi-stage filtration processes can reduce dust and allergens
- Quiet operation: These are much quieter than traditional systems or window units

- Add-ons to current space (an office or family room addition)
- Special space requirements
- When changes in the load cannot be handled by the existing system
- When adding air conditioning to spaces that are heated by hydronic or electric heat and have no ductwork
- Historical renovations or any application where preserving the look of the original structure is essential.
The ideal compliment to your ducted system when it is impractical or prohibitively expensive to use ductwork. These compact indoor fan coil units take up very little space in the room and do not obstruct windows. The fan coils are attractively styled to blend with most room decors.
