A mini-split system is a type of HVAC system that heats and cools one or more rooms without using a system of ductwork.

These systems are also known as ductless HVAC systems, and they're similar to traditional ducted split systems.

An outdoor unit, usually a mini-split heat pump, is a key component of a mini-split system.

This outdoor unit is paired with one or more indoor units, which are responsible for distributing the heated or cooled air.

Mini-split systems are designed to be efficient and effective, and they're often used in homes and buildings where traditional ductwork isn't feasible or desirable.

There are two main types of mini split systems: ductless and ducted.

Ductless systems are perfect for homes without existing ductwork, as they eliminate the need for installation.

Ducted systems, on the other hand, are ideal for homes with existing ductwork, allowing for a more seamless integration.

Some mini split systems can be as small as 12,000 BTU, while others can reach up to 60,000 BTU.

This wide range of options makes mini split systems suitable for various-sized spaces, from cozy apartments to large commercial buildings.

There are several types of mini-split systems to choose from. You can opt for a single-zone ductless system, where one mini-split unit connects to one outdoor mini-split heat pump.

A single-zone ductless system is a great option for small spaces or for heating and cooling a single room. With this system, you can control the temperature in that one room with ease.

Alternatively, you can consider a multi-zone ductless system, which allows multiple indoor units to connect to one outdoor unit. This is perfect for larger spaces where you need to control the temperature in different zones.

In a multi-zone system, each indoor unit can be controlled separately, so you can keep one room warmer and another room cooler, based on your preferences. This level of control is especially useful in homes with multiple living areas or in offices with different workspaces.

Here are some key details to consider when choosing between a single-zone and multi-zone system:

Ductless systems are generally quieter than ducted systems.

The indoor units of ductless systems are whisper-quiet.

You won't hear any "pinging" sounds from expanding and contracting ductwork.

Trane/Mitsubishi outdoor units operate as quietly as 46 decibels.
