If you’re wondering, “What is ductless?“, the answer is simple: a ductless system is a heating and cooling solution that doesn’t require traditional ductwork to deliver comfort throughout your home. Also known as ductless mini-split systems, these innovative HVAC units offer targeted climate control without the need for major renovations or duct installation.
A ductless system from Carrier provides powerful and energy-efficient performance that adapts to your space. Whether you’re living in a modern home, a historic property without existing ductwork, or you’re simply looking to improve the comfort in a specific room or zone – such as a sunroom, garage, basement, or attic – ductless HVAC systems are an ideal solution.
Unlike traditional central air systems, which rely on a network of ducts to distribute air, Carrier ductless systems use an outdoor compressor and one or more indoor units to deliver precise temperature control. This means you can enjoy year-round comfort without the cost or hassle of installing or modifying ductwork.

Why Choose a Ductless HVAC System?

• No ductwork required – perfect for older homes or additions
• Energy-efficient performance to help lower utility bills
• Zoned climate control for personalized comfort in every room
• Easy installation with minimal disruption to your home
• Quiet operation for enhanced peace and comfort

If you’re looking for a flexible, reliable, and efficient way to heat and cool your space, ductless air conditioning and heating systems from Carrier are worth considering. Whether it’s for one room or your whole home, ductless technology gives you the control and efficiency you need – with the trusted performance of Carrier.

PRETTY DARN WELL, IF WE DO SAY SO OURSELVES.

Single or multi-zone systems. Heating and cooling or just cooling. Whatever your needs, wherever your space, however you use it, Ductless systems offer customizable solutions that are efficient and quiet.

SINGLE ZONE

Ductless air conditioners and heat pumps can be installed so that one indoor unit corresponds to one outdoor compressor. The compressor carries refrigerant and power to the interior unit via a small pipe, running through a small opening, installed with very little impact to your home.

MULTI-ZONE

One outdoor compressor can power up to nine indoor units, each separately controlled by a wireless remote, offering you flexible options for configuring your comfort solutions. You can even choose to add units to your compressor in the future after you’ve installed just two indoor units (depending on the maximum number of connectable units), allowing for more streamlined expansion or renovation of your home as time and budget allow.

No ductwork means no patching, no painting and no hassle. Configuring your Ductless system is simple, with virtually invisible installation that requires only a small hole in the wall to connect pipe from the indoor unit itself to the compressor unit outside. The outdoor compressor unit also provides power to the indoor unit, so there’s no need for additional indoor wiring.

Carrier Ductless heat pump systems perform in even the most extreme conditions, providing year-round comfort control, no matter what the weather’s like outside. Even at -22° F, select systems can heat at 80% capacity. They can also cool at 100% capacity when the outdoor temperature is 130° F.

Inverter technology ensures that your system provides precise temperature control while only using the energy that’s needed at any given time. The Inverter compressor automatically adjusts its speed to match indoor comfort needs.

Apart from the energy efficiency of the systems themselves, the configuration options that Ductless units offer can also result in greater energy savings. By targeting only the areas of your home you want to heat or cool, you’re not wasting energy on rooms that are not being occupied or don’t get as much use.

Carrier® Ductless systems deliver pinpointed comfort, no matter where indoor units are placed. Want a cooler home office, but a warmer bedroom? No problem. Because units can be controlled separately, rooms can be set to different temperatures, depending on your comfort needs. Ductless systems also operate so quietly that they can be seamlessly integrated without disrupting even the most peaceful of spaces.

Carrier® Ductless systems can be easily integrated into any home, no matter the demands of the space. With endless configuration options, ductless works where traditional HVAC doesn’t and offers easy solutions for rooms without ductwork or with hot or cold spots. Carrier Ductless systems also allow for a long line length between outdoor compressor and indoor units, offering more options for installation as well as low operating noise, so you can enjoy spending time outside on your deck or inside in your living room in peace and quiet. Ductless systems can also be mixed and matched based on the specific needs of each separate space in your home. High wall units can be paired with ducted, console and cassette units, hooked up to a single outdoor compressor for multi-zone systems.

With filters in each indoor unit, Ductless systems provide cleaner air in the rooms where they are installed. With Ductless, it’s not just about controlling air temperature, it’s about controlling air quality. When circulation is contained within a confined space, there’s no cross-contamination of air between rooms.

For rooms with hot or cold spots, Ductless systems can provide more complete control, targeting those areas with uneven temperatures for more consistent comfort throughout your whole home.

Older homes weren’t built to accommodate the ductwork that goes along with standard modern heating and air conditioning systems. Carrier® Ductless systems allow you to preserve the integrity of your home’s historic architecture without having to carve out spaces for ducts and vents. For low-profile home comfort, console units can be installed into the wall itself without disrupting the formal décor of spaces like dining rooms.

Carrier® Ductless systems can be easily integrated into new architecture, since they don’t require a connection to existing ductwork. No special accommodations need to be made for additional space between walls or above ceilings.

Ductless works best in rooms with tight spaces and/or hard-to-control temperatures. Inverter technology allows the system to run longer cycles at lower fan speeds which helps the system dehumidify while cooling. Less humidity means more comfort, even at higher temperatures in attics and better control of comfort in lower natural-light conditions typical in basements.

Less kids means more space. In a home where some rooms are no longer being used every day, Carrier® Ductless systems can be configured so you only heat or cool spaces when you’re using them, and you can save on energy when you’re not.

In a room with less wall space to hang a unit (as in a sunroom with mostly glass walls), a console unit can be installed detached from the wall on feet, allowing for lower-impact installation.

For a space that may not be connected to your home’s central HVAC, Ductless offers compact cooling and heating power to keep you comfortable all year long.
