Best Ductless Mini Split AC Systems – 2022 Buyer’s Guide

| Last Updated: January 20, 2022

Thinking about adding a room to your house, or wondering why the bonus room that used to be a garage is always freezing in the winter and hot in the summer? In either scenario, a mini-split air conditioner may be the answer to your heating and cooling needs.

Your existing air conditioning unit was selected for the square footage of your home and adding another duct to that system makes it less effective and efficient. This translates to a less-comfortable home and a bigger energy bill. A mini-split system is designed for scenarios where a specific space needs to be heated or cooled.

It’s actually one of the most efficient systems that can be installed in the home. We will take a look at the specifics of mini-split systems, whether one is right for you, and the pros and cons of some popular mini-splits on the market.

Factors to Consider When Buying a Ductless AC

As when purchasing any product, there are a number of aspects to ductless AC units that you should take into consideration before you decide on which unit will be best for you and your needs.

Zone Design

Perhaps the biggest consideration is the unit’s zone design. Ductless AC units come in two different versions: single zone units and multi-zone units. Though this vernacular may sound complicated, it is really just exactly what it seems: single zone units are for cooling only one room and multi-zone units are for cooling multiple rooms, or even an entire apartment or house.

So carefully consider the size of the space you are needing to cool and decide what would be the ideal situation for you. If you are in doubt, go with a multi-zone – it can be easier to add zones than to be dissatisfied with one that is not designed to support more than one zone.


Another factor to consider (and a factor that goes hand in hand with zone considerations) is the BTUs of each unit. BTUs, or British Thermal Units, is the measurement of power to each AC unit, which will directly correlate with the amount of cool air a unit is able to produce. Think about the space you would like cooled and consider the number of BTUs necessary.

Just like with zones, erring on the side of higher is always better when considering BTUs – and, you guessed it, the more zones you have, the more BTUs your unit will require to cool your space effectively.

Energy Efficiency

Of course, the tradeoff with more BTUs and multi-zone cooling options is an increase in your electrical bill, right? Not necessarily! A final aspect to consider when searching for a ductless AC is its energy efficiency. Many of today’s models are produced with the latest in cooling technology and may actually bring your energy costs down, all while keeping you nice and comfortable in a cooler home.

What Is a Mini-Split Air Conditioner System?

The main difference between a traditional air conditioning system and a mini-split is that traditional systems have ductwork and a mini-split does not.

A traditional system uses a blower to suck air from the house through the ductwork and into the main unit’s blower, and then pushes it through an evaporator, which removes the heat from the air. The system continues to push the cooled air out of the system, into more ductwork, and back through the vents in your home. So air from throughout your home is funneled into the main unit, cooled, and returned to the various rooms in your home via ductwork.

A mini-split still operates in the same way, except that it only has to push the air from one room through its evaporator. Instead of having to pump air through ducts that are in the basement, crawl space or attic, it is simply pulling air into the unit from the room it is physically located in, cooling the air, and blowing it right back into the same room. The air never leaves the room it is in.

You might be wondering how a mini-split differs from a window or through-the-wall unit often found in hotels. The obvious answer is that a mini-split unit can be mounted anywhere in a room while a window unit has to be in the window. This makes mini-splits the more secure and aesthetic option.

The most important difference in a mini-split compared to window or through-the-wall units is the location of the noisy compressor. Window units and through-the-wall units are completely self-contained. This means the noisiest part of any air conditioner, the compressor, is in your home when using a window or through-the-wall unit.

A mini-split is like a traditional split-system air conditioning unit because the compressor is in a separate unit outside. The only things connecting the two are the copper lines used to pump the heat transferring refrigerant between the two systems and wiring. A mini-split is much quieter than any of its competition because its fan is much smaller than a traditional units fan because there is no need to move air through ductwork.

In short, mini-splits are more efficient than traditional units because of the absence of ductwork. But they are designed for cooling and heating individual spaces, rather than entire homes. mini-splits are more efficient, versatile, and much quieter than window units and other self-contained options.

Best Ductless Mini-Split Brands

Although ductless mini-split air conditioners are not nearly as popular or as well-known as other, more traditional air conditioning options, such as window units or freestanding ACs, that is just because these types of units are relatively new to the market. 

Once more people know about ductless mini-split ACs, we guarantee their popularity will surge, so it is worthwhile to know which brands produce reliable units and which brands are not so awesome. Here is a list of trustworthy ductless mini-split AC brands:


Pioneer may not be the best-known or most easily recognizable out of all of the air conditioning brands out there, but that does not mean it does not produce reliable, high-quality units that will always get the job done for you.

One of the ductless mini-split air conditioning units we have reviewed below as one of our top recommended units is a Pioneer and for good reason. Pioneer strikes an excellent balance between price and quality, and you will not be left regretting your decision when you go with a Pioneer.

Plus, they are one of the simplest air conditioning units to install on your own, which will also help you potentially save thousands of dollars by not needing to call in an HVAC technician (more to come on that situation later in the article). If you want the most bang for your buck, you should definitely go with a Pioneer.


Friedrich is a trusty brand that most people will associate with quality air conditioning units, thanks to their wide range of different types of units that they process and sell. And the Friedrich guarantee extends to their ductless mini-split air conditioning units as well.

Users of Friedrich mini-splits report that these are some of the best units when it comes to cooling spaces evenly, even in the case of a space that connects to another space or has a weird and unusual shape that could negatively impact cooling potential. Friedrich rises to that challenge and then some.

Plus, Friedrich is one of the best air conditioners when it comes to working effectively and reliably even in extreme heat scenarios. In today’s age of drought, global warming, and heat waves, you will never be able to predict when the next record-breaking temperature will be, and you want a unit that will be able to stand up to whatever Mother Nature throws at it. Friedrich has got you covered.


LG is well known for producing a wide variety of brands and devices on the market today, and their expertise can be trusted when it comes to all electronic systems, so you know you are investing in something reliable when you choose an LG ductless mini-split air conditioner.

LG models take the staples of the air conditioning game – lack of noise and effective cooling – and bring them to the next level. They do this by adding in a number of other awesome features designed to make your life easier. LG models often have some sort of remote control system, so you will be able to tell your air conditioner what to do without needing to physically adjust something on the interior (or worse, exterior) unit itself.

Plus, in keeping with the typical LG branding, these models are certainly much sleeker than many of their competitors. LG knows most people do not want a bulky, clunky, obvious air conditioning unit, and intentionally designs their units to be as unobtrusive as possible – or to look like something else entirely, as some models come with a photo frame that makes the whole unit just look like a cute decoration. If aesthetics is your primary concern, you have got to go with an LG.


Mitsubishi?? You may be wondering…don’t they make cars? Yes, they make cars, and yes, they make telecommunications products, and yes, they make mining gear, and yes, they even make ductless mini-split air conditioners!

If you have ever spoken to anyone who drives a Mitsubishi model car, you know this brand is to be trusted, and that reliability certainly extends to their air conditioning units as well. One of the best features that Mitsubishi’s mini-split ductless air conditioners are able to provide to their users is premium energy efficiency.

And of course, that is one of the biggest considerations most people have to make when they are choosing to invest in an air conditioning system at all, let alone a mini split unit – how much is it going to increase their electrical bill? Is the tradeoff between spending more money and getting cooler air really worth it? With Mitsubishi, the answer is a resounding YES, because their energy efficient cooling systems will barely increase your electrical bill at all. If you want cool air without the stress of more money, you have got to go with a Mitsubishi.

Heat Pump/Ductless vs Normal AC

Most people have never heard of a ductless air conditioner, much less a ductless mini-split air conditioner. What the heck are we even talking about? Don’t most air conditioning units just sit in windows or stand on the floor? How can they even cool multiple zones, anyway? Don’t worry – we are about to lay it all out for you.

It is true that ductless, mini-split air conditioners are not as popular as traditional window or freestanding units. But they are gaining in popularity because they are extremely effective at cooling spaces, particularly multiple spaces as mentioned above.

Ductless mini-split air conditioners may sound complicated, but they are actually quite simple. They are referred to as “split” because they come with separate units: an exterior unit that contains the compressor and does all of the intense work, and one or more interior units that are much smaller than the exterior unit and actually project cool air into the space.

They are referred to as “ductless” because they do not require any ductwork, simply a connection between the evaporator and condenser, as well as a drain line. They are a more sophisticated cooling system than traditional air conditioning units. But they also require a lot more effort to initially install – so much so that in some cases, for people who do not have a lot of HVAC experience, it may be worth it to call in a professional technician. However, once they are installed, you will not have to worry about noise, vibration rattles, or a huge ugly window air unit disrupting your carefully decorated living room – just sit back, relax, and enjoy the cooler air.

How to Choose and Install a Mini-Split System

Configuring how many BTU’s you need per square foot is not very difficult with the resources of the internet and some basic math. But installation of a mini-split is more similar to a traditional central heating and air unit than a window unit you can purchase at the local box store. They require high voltage wiring, the ability to braze copper lines, a multitude of other specialized skills, proper licensing, and extensive knowledge of building codes.

It is a good idea to do as much research as possible about different models of mini-splits before making a decision. However, you will need a certified technician to install your mini-split unit and it is best to consult with the contractor you will be using for installation before purchasing a unit you are interested in.

Pros and Cons of Mini-Split Systems

As with nearly anything in life, mini-split systems have their advantages and disadvantages. Let’s look at some of them.


Mini-splits are very efficient because no air is lost to small leaks in the ductwork, and the air does gain or lose heat traveling through ductwork. Whether you are looking to lower your energy bill or your carbon footprint – mini-splits do both.

This is an easy solution to additions to your home. Your home’s system was chosen based on the square footage and other specific dimensions. adding an additional room to your current system will make that system less effective and efficient.

We spend a lot of time worrying about the quality of the food we eat and the water we drink, but we often overlook the importance of the air quality inside our homes. Ductwork is one of the key contributors to poor indoor air quality. Mini-splits do not use ductwork and do not expose you to the air in your basement, crawl space, or attic.

Mini-splits are quicker to install, have small – easily hidden – outside units, and have minimum impact on the structure as less space is required for installation.

They are a safe and secure alternative to inefficient and outdated window units, space heaters, and electric baseboard heaters for heating individual rooms.


The initial cost of mini-splits is much higher than other heating and cooling solutions, per room. Each room has to have a separate indoor unit installed, while traditional units only have one indoor unit per floor. The initial cost of a mini-split is much higher than a window unit or self-contained unit designed for one-room use.

A mini-split’s heating mode utilizes heat pump technology. As with any heat pump, they may not be able to sufficiently heat homes in sub-zero conditions. A fuel-based furnace will likely be needed as a backup in these types of climates.

Mini-splits require frequent maintenance. Each unit’s filter has to be washed at least monthly because they are very sensitive to debris accumulation.


We have discussed the differences of mini-splits from other types of HVAC units and taken a look at the various specifications, pros and cons, and models of mini-splits that are available.

We hope you can use these comparisons to come to an informed decision about the mini-split you wish to purchase. Remember, it is always wise to consult with HVAC professionals before purchasing or attempting to install any air conditioning unit.

People Also Ask

A mini-split comes in handy during hot summers to provide a cool environment. Manufacturers incorporate multiple features in their products to make them stand out from the rest. People, however, still have some confusion regarding the functionality of mini splits. Therefore, here, we have tried to answer some of the frequently asked questions of people to help them make an informed decision.

How Does a Ductless Mini Split Work?

Ductless mini splits work on the same principle as central air conditioners. The only difference is they lack any air ducts as these are designed to cool only a single room rather than the entire home. These models work efficiently in sucking the warm air and moisture from the room and dump it outside.

How Much Does a Ductless Mini-Split System Cost? 

The cost of ductless mini splits varies depending on the size and BTU value. It generally ranges from $2000 to $14,500 for most of the systems. Generally, the average price of a 12000 BTU system is around $3000. Similarly, a 1-ton AC can cost you $1000-$4000, depending on the brand it comes from. Finally, the installation and labor cost additional $300-$1000.

How to Hide a Ductless Mini Split?

You can hide ductless mini splits in multiple ways. You can either try hiding it in a built-in bookcase or might tuck it in a corner. Similarly, you can also build a cabinet around the unit. Moreover, design a wall shelf across the wall where you intend to install the indoor unit of the split AC. Since these units come in neutral colors like white and grey, you can paint the wall according to that as well.

How to Size a Ductless Mini-Split System?

The size calculation of a ductless mini-split system requires you to take various factors into consideration. One of the simplest methods is to multiply the length and width of the room to get its square footage. Multiplying the area with 25 will give you an estimated BTU output value needed for that room. You can use this information to size the heat pump.

Cost of Ductless Mini-Split vs Central Air

Mini splits relatively cost you more than the central ACs when it comes to installation. However, they tend to offer significant savings on the monthly bills in the long run. An efficient 1-ton mini split usually ranges from $1000-$4000. On the other hand, the average price of a central unit lies between $3500 and $5000.

  1. I purchased a Fujitsu Mini-Split heat pump in the fall of 2016. In January of 2018 it ceased working and I have been without it now for 2 1/2 months during the coldest weather of the year and Fujitsu has shown no interest in repairing or replacing the unit. In fact, they have continuously lied to my dealer and myself about how long it would take to repair and now for weeks they have lied about shipping it back to me, saying it is shipped when it has not.

    This in no way reflects on my local dealer, Haynes Heating and Air. Haynes has gone out of their way to help me and is being misled just as I am.

    I should have been more careful. I thought that by doing business with a Japanese company that I was assured of doing business with people who are honorable and ethical. But when my unit broke I discovered that the ‘warranty’ only covers parts, not labor. I wish I had seen that before I bought, It would have frightened me off. Luckily, there has been lots of labor involved here and Haynes is eating all those charges, even though they do not have to do so.

    But Fujitsu has been of zero help, and they will tell Haynes whatever they have to just to get them off the phone. They have had the unit in their shop at Fujitsu for all this time because they could not figure out what to do to fix it in the field. And now they have been saying for three weeks that it is shipping when it isn’t. And they had the nerve to say that they were ‘backed up’ and that is the reason they took so long.

    Customer Service does not allow for this. Honor would demand that they replace the unit if they could not fix it in a reasonable amount of time. You just do not take a customer’s heat source from them in the middle of winter and act like it is unimportant to get it back to them.

    Mini-Splits are great. But choose your manufacturer very carefully. Make certain you do business with honest, honorable people who understand the value of a good reputation. I did not do that. I did business with Fujitsu and have lived to regret it. Don’t repeat my mistake.

    Fujitsu has just reported that my unit has once again ‘shipped’. We shall see. I will update this post with more details when and if the unit arrives and can be made to work. I am not optimistic.
