Anyone who’s built from scratch or renovated has given lots of thought to the best ways to heat and cool their space. Ductless mini-splits are a great option to consider because of their efficiency and flexibility. Today, we’ll talk about how ductless mini splits work. We’ll also provide some guidance to help you choose the best unit for your home.

What are mini-splits?

A ductless mini-split is a heating and cooling system that doesn’t use air ducts. It’s a split system with one indoor and one outdoor component. The outdoor component can support several indoor units, which each service separate rooms or areas. These systems are much more compact than traditional HVAC systems.

Since they’re so versatile, ductless mini-splits are a popular solution for heating and cooling.
Depending on your needs, they can function as a standalone system or as a companion to your
current HVAC system. What’s great about them is that they can be installed anywhere in your
home since they’re ductless. They’re commonly found in finished basements, garages, and

How Ductless mini-splits work?

Ductless mini-splits operate by pulling from your home’s electrical power. They consist of an
indoor evaporator, to circulate air, and an outdoor compressor, to condition the air coming in.
The outdoor compressor soaks up heat from the outdoor air and moves it indoors. The indoor
evaporator spreads it around your space. One system can easily support multiple indoor units,
allowing control of your home’s temperature in each room. For larger homes, the system can be
scaled up by installing an additional compressor.

What are the benefits of mini-splits?

Ductless mini-splits have many benefits. For one thing, they offer a higher level of control over
the temperature in your home. Since each unit services a separate area, you can customize your
space however you see fit. Additionally, mini-split systems are very energy-efficient. They use
variable-speed compressors, which means they run as little or as much as you require. This helps
reduce energy usage.

Choosing the Right system for your home

There are a lot of great mini-split systems out there. When deciding which one is best for your
home, consider the following factors:

1. Energy efficiency and savings

When comparing models of ductless mini-split systems, it’s a good idea to look at the SEER
(Seasonal Energy Efficiency Ratio) rating. This measures an HVAC system’s efficiency. Some
of the best models are LEED zero certified, which means they’re recognized for net-zero
emissions from energy consumption.

2. Aesthetics

Since HVAC systems prioritize function over form, their appearance is an afterthought. Ductless
mini-splits are installed in the space they’re servicing. Their visibility has led manufacturers to
develop several low-profile options. Some models can even be installed in places like the floor
or ceiling, exposing only the vents. This is a great solution for concealing the unit.

3. Performance

All ductless mini-split systems provide cooling, and only some provide both heating and cooling.
This is an important factor to consider, depending on your climate and the solution your space
