Step 1: Choose how many zones or rooms you need to heat/cool
In most cases you will have a zone for each room, however there are instances where you can use a unit to cover several different rooms based on your home’s layout. If you are unsure how many zones you need, please contact us!

A single-zone mini split system includes one indoor unit and one outdoor unit, making it ideal for heating and cooling a single room or space. This option is perfect for home offices, garages, sunrooms, or room additions where extending ductwork isn’t practical. If you only need temperature control in one area, a single-zone system is the most efficient and cost-effective choice.
A multi-zone mini split allows you to connect multiple indoor units to a single outdoor unit, creating independent temperature control in multiple rooms. These systems are great for homes or businesses looking for zoned comfort without the need for ductwork. Dual-Zone Mini Split (2 Zones) – Ideal for heating and cooling two separate rooms, such as a living room and bedroom, or a master suite with an adjoining office.
A multi-zone mini split allows you to connect multiple indoor units to a single outdoor unit, creating independent temperature control in multiple rooms. These systems are great for homes or businesses looking for zoned comfort without the need for ductwork. 3-Zone Mini Split (3 Zones) – A great solution for three connected areas, like an open-concept living space or multiple bedrooms.
A multi-zone mini split allows you to connect multiple indoor units to a single outdoor unit, creating independent temperature control in multiple rooms. These systems are great for homes or businesses looking for zoned comfort without the need for ductwork. 4-Zone Mini Split (4 Zones) – Perfect for larger homes or businesses where multiple rooms need individual climate control.
A multi-zone mini split allows you to connect multiple indoor units to a single outdoor unit, creating independent temperature control in multiple rooms. These systems are great for homes or businesses looking for zoned comfort without the need for ductwork. 5-Zone Mini Split (5 Zones) – The best choice for whole-home comfort, allowing up to five rooms to have separate temperature settings.

FAQs
A ductless mini split air conditioner presents a contemporary approach to indoor climate management, offering unique advantages that distinguish it from traditional central air systems. Unlike centralized air conditioning, which relies on ducts to circulate air throughout a home, ductless mini splits operate on a zone-by-zone basis. Each room or zone is equipped with its own sleek air handler, typically mounted inconspicuously on a wall or ceiling, and connected to an outdoor compressor unit via a small conduit. This configuration enables precise temperature control tailored to individual preferences in each zone, enhancing comfort and optimizing energy usage by only conditioning occupied spaces. The absence of ductwork eliminates energy losses associated with air leakage, resulting in greater efficiency and reduced energy costs over time. The mini split heat pump operating as a ductless HVAC system, delivers both heating and cooling capabilities in a single unit, offering flexible comfort solutions throughout the year. By extracting heat from the outdoor air and transferring it indoors during colder months, mini split heat pumps offer energy-efficient heating without the need for ductwork. The versatility of ductless mini splits extends to installation options, making them suitable for various architectural styles and configurations. Whether in new constructions or existing homes, the absence of ductwork allows for easier and less invasive installation, minimizing disruption to the living space. Many ductless mini split models come equipped with advanced features such as remote control and Wi-Fi connectivity, enabling convenient monitoring and adjustment of settings from anywhere via smartphone apps or other smart devices. This level of control empowers homeowners to manage their indoor environment efficiently and effortlessly.
The installation process for a mini split system is much easier than that of a traditional system. This comes from the inherent simplicity of a mini split unit. Ductless mini split air conditioner systems consist of two main parts. The first is an outdoor compressor or condenser. This is paired with one or more indoor air handling units (these are the devices that you can see inside a structure, as they actively heat and cool rooms). Another great feature of ductless air is the variety of air handlers available, including:
- Wall Mounted
- Ceiling Cassette
- Concealed Duct
- Floor Mounted
The outdoor and indoor components are connected by simple conduits — generally referred to as “line sets.” Those usually include: a drain line, refrigerant tubing, suction tubing, and a condensate drain, wrapped in a durable insulation. The result is a 3-inch line that delivers all that is needed, meaning homeowners need only make a single entrance hole into their home.
Mini split AC installation is remarkably simple, especially when compared to the need to build out complex duct networks for a central air system. Most installations follow a 4-step process:
Installing the condenser (this happens outside)
Running refrigerant lines through a 3-inch hole in the exterior wall
Installing the air handlers (these go indoors) and attaching them to the refrigerant lines
HVAC technician charges the system by vacuuming the line sets
There is also the option of using pre-charged line sets to make installation especially easy, so much so that many people can do it themselves. DIY systems available for homeowners carry manufacturers warranties and bypass the costs of professional installation
