A Ductless Air Conditioner and Heater in One Simple System
A ductless system, sometimes called a mini-split or a ductless air conditioner and heater, gives you quiet, efficient heating and cooling without the need for ductwork. It’s a flexible, energy-saving solution that works beautifully in Washington homes of all ages, especially those with additions, older layouts, or inconsistent comfort.
Below, you’ll find a simple breakdown of how ductless systems work, why homeowners are switching, what installation looks like, and how to choose the right system. You’ll also find deeper guides and resources if you want to explore specific questions.
What Is a Ductless System?
They’re a great fit if your home currently uses:
- electric baseboard or wall heaters
- propane or wood heat
- window or portable AC units
- an older or unreliable HVAC system
Why Homeowners Love Ductless

Most homes can be installed in just a few hours with minimal disruption.

How Ductless Systems Work
A ductless system has two main components:
- an outdoor heat pump unit
- one or more indoor units mounted on the wall or ceiling
These are connected by small insulated refrigerant lines, no ducts required.
In the Winter
It extracts heat from the outdoor air (even when cold) and brings it inside to warm your space.
In the summer
The system removes heat from inside your home and moves it outdoors.
This approach keeps your home comfortable year-round while using significantly less energy.
Why Ductless Systems Are So Efficient
This means:
- fewer temperature fluctuations
- reduced energy use
- quieter operation
- longer system life

Our customers that install a new ductless system see a major reduction in their heating costs throughout the year, often saving 25%–50% or more on monthly heating bills during the cold winter months. Ductless systems also provide cooling during the summer, making them an incredibly versatile choice for Pacific Northwest homes.
Ductless mini-splits are good for both heating and cooling your home. A ductless system will keep you and your family warm in the winter and cool all summer long.
Yes, ductless heat pumps work very well in cold weather. Your mini-split can usually heat to a low outdoor temp of -5 degrees, or in some cases lower. Its efficiency keeps your home comfortable on its own most of the time. However, on those extremely cold days, if you feel your ductless system needs a boost, you can run your backup heating system in addition to or instead of it. Although running only your ductless system will be the most efficient, adding a backup heating system on the coldest of days is okay, too. It ultimately depends on your comfort preference.
A ductless heat pump system operates without the use of ductwork. It's great for older historic homes without ductwork, or for newer additions to a home, such as for a sunroom, mancave, garage, or other add-on.
With property maintenance and care, a ductless heat pump can last up to twenty years or more.
