Ductless mini-splits or HVAC systems have seen tremendous growth over the past few years. According to statistics, from the year 2019 to 2025, its market is estimated to grow by $39.2 at a growth rate of 7.4%, in the US alone and it is expected to reach a whopping $662.7 billion globally by 2025.

Ductless heating & cooling systems are quite effective & efficient in terms of how they operate and save money. One of the biggest advantages of them, however, is “zone cooling” and it is one of the top reasons why people prefer to buy ductless mini-splits.

So whether you are a domestic user or a business owner constantly listening to customers’ complaints regarding the space being too cold or too hot, ductless mini splits have your back. If you wish to learn more about them, continue reading. We are going to cover topics such as what is a ductless mini-split? How it works? And some of its advantages. So without further ado, let’s dive into it.

What are Ductless Mini-splits and How do they work?

Mini-split heating & cooling systems allow you to control the temperatures of a specific room or space without any hassle. They consist of two main units; an outdoor compressor condenser and indoor air handling unit.

Similar to a traditional air-conditioning system, ductless mini-splits use copper tubing to carry the refrigerant from the outdoor (containing the compressor & condenser) to the unit inside. However, instead of being routed via the ductwork, the air blows directly out of the indoor air handler in a mini-split system.

While 4 to 5 air handlers are typical for domestic use, the number of zones can be increased if you have a business such as a motel, school, or hospital. The air-handlers are installed in different spaces of the building to work effectively. There’s an array of indoor units that can be mounted in different locations such as the wall, floor, and ceiling.

Ductless mini-splits come in quite handy during winters too. They will heat the space via a ductless heat pump system. Like conventional heat pumps, these connect an indoor air-handler to an outdoor compressor condenser. However, in a ductless heating system, the air handler is installed directly in the room and does not require any extra ductwork to blow the conditioned air inside.

Advantages of Mini-split Heating & Cooling Systems

Ductless mini-splits are an ideal choice for places with both warm and cold climates. However, if it is a subzero temperature region, addition of a backup heating system will completely solve your problem.

They are the go-to choice for structures where ductwork cannot be installed or if it is heavy on the pockets. Ductless HVAC systems can be installed fast and with ease. Moreover, they are also efficient in reaching higher SEER ratings compared to ducted ones. Let’s take a brief look at some other advantages of this system.

It is Super Quiet and easy to install

Traditional cooling systems are quite inefficient, in that, they are problematic to install and they make a lot of noise. The space may have sliding windows, so a typical window AC won’t fit into it. Another option is to insert a sleeve through the wall and mount one there. That, however, will probably require a 220-volt electrical outlet and a huge hole in the wall.

A mini-split saves you from all the hassle as it only needs a hole in the wall about 2 to 3 inches deep for the lines to connect with the outside unit. The best part is that it is super quiet. So you get the desired temperature and peaceful sleep as well.


One of many problems with conventional heating and cooling systems is that the ductwork has to go somewhere through the premises. Maybe, through a crawl space, the attic, or another place behind the walls. This may cause leaks and also require insulation as well.

Unlike traditional systems, ductless mini-splits use a powerful fan that blows air throughout the house and has a swinging louver to efficiently spread the air throughout the room. Installing a ductless system also means no leakages and no holes required. Saving you valuable time and energy.


Ductless mini-splits offer lower total costs compared to traditional air-conditioners. One way it helps reduce expenses is in terms of new installations and all associated costs. Especially, if you are upgrading from an older system or replacing multiple window or portable units.

It also helps save a considerable amount of money because of its enhanced energy efficiency, reduced air loss, and the zoned heating and cooling feature, which allows for maintaining the desired temperature of only the rooms you want.

Types of Ductless Mini-splits

Choosing the right mini-split system for your home or business requires a bit of research to meet the desired requirements or complement the aesthetics of the space. Here’s a list of some of the most popular variants:

Single-Zone Mini Split

It comprises a single indoor and outdoor component and helps maintain the temperature of a specific room or space.

Multi-zone Split

This variant can have upto four indoor units for a single condenser. One beneficial feature of multi-zone mini-split systems is that every unit can function independently, even though they are connected to each other.

Wall-mounted Mini-splits

They are mounted near the wall tops. This is one the most popular types of mini-splits because of its cost-effectiveness.

Floor-mounted splits

These are similar to the wall-mounted version. The only difference is that they are mounted close to the floor. It is an ideal choice for spaces where there are big windows or the ceilings are too low.

Ceiling Cassette

Ceiling mounted or ceiling cassette mini-splits are also quite popular for their efficient use in hotels, hospitals, banks, and other similar types of businesses. As the name suggests, they are installed in the ceiling instead of floors or walls.

Besides all the other benefits of mini-splits, these give a clean look because of their discreteness, they take no livable space, and they have a customizable air flow option.

Choosing the right HVAC system for your business is essential for efficient performance and cost savings. To do that, a thorough knowledge of all systems is required. At ProServicesSupply, we can help you do that. So get in touch with us today before installing your next ductless mini-split.
