Over the last decade, you may have noticed the euphoria of ductless air conditioning systems gather steam. Many product shows have been characterized by original equipment manufacturers (OEM) marketing “newer and better” sources of indoor comfort. Such tactics and the warm reception from the public would make the majority of homeowners think that central air conditioners are living on borrowed time. Ductless systems, also called mini-split systems are based on a new concept that offers consistent performance and higher energy efficiency. Of course, they have their cons, but their advantages have many property owners talking. Kim Dionne, who is a homeowner in Manchester, Connecticut, points out one of the benefits of this technology as, “There is more temperature control because each room has an individual remote, so I can set it to the temperature I want.”

Being used to conventional solutions would undoubtedly make it difficult for some people to decide to switch to newer technology. That’s why we were not surprised to many people wondering whether mini-split systems are any better than central air conditioners. Although we opine that they are better, we will let you make that verdict. For now, we invite you to read on for our discovery of some of the best ductless air conditioners in the market today according to our extensive analysis. We have summarized our choices for Best Overall, Best for the Money/Most Value, The Budget Pick and Most Energy Efficient, but we believe the entire read will be exciting and helpful.

Types of Air Conditioners

In our scrutiny of the best ductless mini split air conditioner & heat pumps, we find it worthwhile to mention other space cooling options. Portable Air Conditioners, through the wall air conditioner, Window Air Conditioners and Central Air Conditioning Systems are other home cooling solutions. A portable air conditioner is mobile and can be moved from one space to another. It can be placed on the floor, but will often need a vent kit for disposal of moisture and hot air. Window air conditioners are placed on the window frame so they can drip water outside. They are small-sized and simple to install. Different advancement in these types means the quality of service offered may vary greatly. For instance, some are capable of cycling on and off, while others need user-control. Central air conditioning systems are the most common in homes. A number of components characterize the central a/c system, but the system can be divided into the outdoor part and the indoor part. The most distinctive of the components compared to other types of air conditioners is the ductwork, whose work is to distribute air to each room.

What is a mini-split system?

All ductless air systems contain indoor and outdoor components as the basic features. Starting the process of air conditioning from the outdoor apparatus, the condensing unit compresses the refrigerant and forces it through the connecting lines towards the indoor unit. The indoor unit carries the evaporator coils, air handlers, and blowers. For efficient energy consumption, the air-handling units will be located strategically across the home. The noisier condensing unit is placed outside to maintain quiet inside the rooms. Typically, what we refer to as a mini-split system is that small unit fixed on the wall or ceiling that carries a pair of refrigeration lines for heat transfer from the home.

The terms “Ductless” and “Mini-split” are regularly used interchangeably in air conditioning. The system we are analyzing is ductless because it does not have any network of pipes and boxes that characterize some of the options we mentioned. A ductless system can render all these bulky components unnecessary.

NB: about a third of all energy consumed by central air conditioning systems is lost through ductwork, especially if these components are in the attic or similarly uncontrolled space.

Split” is a term used to depict that the system comprises of separate but interconnected parts. The major components of the unit are an evaporator unit (air handler) and a compressor unit. The noisier compressor is located outdoors while the evaporator is placed indoors. Window-type air conditioners are normally noisy because these components are within a single unit and are placed indoors. For the mini-split system, the compressor unit is placed away from the occupants, thus guaranteeing a quiet environment.

Ductless air conditioners are “Mini”, meaning that they are often small-sized. Our experience with these gadgets suggests that even with their small sizes, they are better than conventional systems in many areas- versatility, energy efficiency, operating costs, installation costs, etc. You will find instances where “multi” is used instead of “mini”, which simply means that there are several indoor components involved.

The outdoor and indoor units of this system are connected using wires and pipes that go through a small hole in the wall. Three inches are enough for these components. Wiring is needed for powering the unit while the tubing harbors the refrigerant.

Categories of Ductless Air Conditioning Systems

In categorizing a mini-split system, we are simply talking about the different configurations possible for different home conditions and system workings. We chose to adopt these three categorizations:

Single-Zone Ductless System: If you are interested in target cooling, this system is ideal. It mostly suits attics, garages, basements, small building and such places.

Dual Zone Ductless System: This arrangement allows you to manage the comfort level of two zones/rooms.

Multi-Zone Ductless System: If the ductless A/C technology has impressed you and you want to use it in the entire home or office, it is still possible. All you need are several air handlers for the different sections/rooms, but the compressor remains as one. Modern mini-split systems are capable of serving as many as eight units. Individual rooms are able to generate their own environment using a thermostat. That means no more arguments among occupants! It may also be referred to as a multi-split ductless air conditioning system.


As you enter the best ductless mini split air conditioner & heat pump market, we can assure you that you will find a crowded market. A disclaimer before we proceed: There are countless options on ductless air conditioners alone, to the point that it is a herculean task to cover everything in a single article.

Reasons to Consider a Ductless Air Conditioner

There are many aspects of making a home comfortable, but temperature management ranks up there. Unless you have no problem with discomfort during summer, you want to cool your space properly. Homeowners in cold climate regions tend to focus on heating, forgetting that sweltering heat has its own downsides. This explains the predicament for many users because quality indoor air quality (IAQ) has links to improved concentration, better sleep and generally, a better life. An answer to this dilemma might be the installation of the ductless air conditioner.

Mini-split systems are often ideal alternatives to conventional central air systems in places where ductwork is inexistent. Ordinarily, this happens for older homes of the era when standard ductwork had not entered the construction world. Ductwork installation can demand up to $10,000, so installing ductless systems instead comes as a perfect option for the same or even better indoor convenience.

That is not to say that homes carrying ducted systems cannot present the benefits of ductless systems. Indeed, there are cases where you may be prompted to use a ductless system in your modern property. We have seen homeowners opt for a mini-split system after learning about possible energy savings or better temperature control. Sometimes, ducts that are five or six decades old will start to leak, leaving the owner with no choice but to seek options for improved performance and efficiency. Ductless air conditioners come in handy in such scenarios.

Central air systems have their benefits, but they come short in one area- customization, yet a good quality ductless mini split air conditioner & heat pump scores the most points here. Some of the options presented by mini-split systems and that could allow customization for homeowners is wall unit for temperature adjustments, ceiling cassette, and multi-zone/single-zone units.

Below is a little more coverage of the benefits.

Quiet Performance: since the compressor is outside the house, only the fan produces a little noise. If there is any noise, maybe it will be something akin to a whisper. You may even be prompted to check the system controls to be sure everything is fine. This feature enhances user comfort.

Ductwork Absent: these systems do not need ductwork; hence, there is no worry about inefficiencies caused by cracks and leaks. Users of these systems can breathe count themselves safe from allergens and asthma-causing conditions associated with central air conditioners.

Simple Installation: the hardest part of installing most mini-split systems is probably drilling a hole in the wall to accommodate the refrigerant line. Some manufacturers have even eliminated that challenge by making lines that can go the entire length of the house. While the task is simpler than in central systems, please note that most manufacturers recommend that professional installers do the installation for you.

Zoning:  Cool only rooms or sections of the home that need cooling. Ductless air conditioning systems do not waste energy as they allow you to choose the spaces you want to serve.

Secure: The best ductless air conditioners of today are designed and built with reliability in mind. They are not only built to last, but also have automatic self-diagnostic capabilities. Some will even self-lock in case of unauthorized access.

User Control: The advancement of mini-split systems has seen the rise of products of smart solutions. For instance, Wi-Fi enabled systems have brought user control to a level never seen before, whereby you can do a lot-set temperature, diagnose the system, turn off, etc. – via a phone app. As long as you have a smart device with the particular app installed, you can control the system from anywhere in the world.

Environmental Friendliness:  The best mini-split air conditioners use the safest refrigerants available. These refrigerants are made from recyclable components and are non-ozone-depleting. This is a marked departure from older technology, which used dangerous refrigerants, a perfect example being Freon (HCFC-22/ R-22). This refrigerant must be phased out of production before January 2020, according to EPA guidelines.

Handling Extreme Temperatures:

Mini-split air conditioners are designed using the most advanced technology. They are capable of handling extreme heat, such as a heat wave. They often present superior performance compared to older systems, thus providing excellent comfort regardless of conditions.

Indoor air quality (IAQ): These units come with some of the most refined air filter technologies. Alongside removing 99.9 percent of contaminants from the air, the filters are capable of deodorizing the air for ultimate satisfaction of users. Improving IAQ is the biggest benefit from this solution, but there is also the aspect of enhanced system reliability. Filters keep harmful objects from the unit, hence promoting the performance of components. The filters are usually easily accessible for maintenance and replacements. Our research has also shown that these filters tend to last more than conventional ones do.

Renting Vs. Buying a Ductless Air Conditioner

Buying and renting are both possible ways of enjoying the services of the ductless air conditioner of your choice. Many users have deemed renting a smooth experience, but others opt to buy the product and keep it to avoid ownership-related problems. When all is said and done, you make this important decision. If you are finding it hard to do so, the following breadth of view can be helpful. For renting, you want to deal with a reputable company, one that is swift to replace parts and provide tune-ups as and when required. Other important factors are number of years of operation, types of services offered and number of customers it serves from time to time.

If you opt to rent the unit, monthly rent may be the only cost to give you headaches. Some providers give you the option of buying the product at any instance as well. Since the renting company wants the product to last long, they will have a high-quality one and will subject it to the best maintenance possible. Be careful not to be locked into an unfriendly lengthy contract though.

Though there are upfront and maintenance costs to consider, we think that buying makes sense from the perspective of owning the asset. It means that even when you decide to sell your property, the system will be part of the value addition. Moreover, governments are nowadays offering friendly rebates that make buying hassle-free. Individual sellers can also provide manageable financial plans that reduce upfront costs significantly.

What You Must Do Before Picking a Mini-Split Air Conditioner

Getting the advice of an HVAC professional is usually the best way to establish if you need a ductless air conditioner. The size and type of space you have are just some of the important considerations. It is not always a definite decision, but we believe these suggested stages can help:

HVAC Expert Visit:  The purpose of inviting the professional to your property is to have a thorough residential load calculation done. Cooling and heating processes have their own complexities, but the expert can bring all these to the table. Some aspects that may interest you are sunlight direction, the color of the roof, insulation level and so forth. The resulting report should reveal the required BTU/hr. for every room. This information is crucial as it helps determine the best ductless heating and cooling systems.

Room/Space Size: Even as the HVAC expert performs these analyses, it is advisable for the homeowner to carry out own measurements of mini split BTU per square foot. It may not be the final data used to pick the products, but it provides a rough estimate of the expected investment.

Installation spot: By now, you know that the indoor unit of a ductless air conditioner installs on the wall or roof. It may even be fixed on the floor, depending on the accommodation of the house. We know that homeowners sometimes have preferred location for the unit, say a certain corner. If you have an idea about the size of the unit, please go ahead and measure the space to ascertain that your idea can work.

Budget: For the air conditioner installation project that you are planning to undertake, you must have a budget in mind. The budget normally covers equipment cost and installation works- we insist that it is better to have an HVAC professional perform the job rather than the DIY approach.  If your budget is strained, you can still use this solution, albeit for limited sections such as the living room or bedroom alone.

What are the important considerations before installing the air conditioner?

A mini-split a/c setup may carry one or several indoor air handlers, each located in an individual room. Consider the following installation guidelines:

  • The wall carrying the unit should be sturdy enough to offer support for many years
  • Remove any obstructions to the unit, examples being chairs and wall units
  • Position the air conditioner away from sources of heat such as ovens and unobstructed sunlight
  • To ward off electrical noise, place the unit at least 3ft. away from modems, mobile gadgets and electrical wires

What Factors Should I Consider When Buying The Best Ductless Air Conditioner?

You will realize that the many options available present a broad range of sizes, prices, features and power and so forth. A well-structured choosing criterion can help pinpoint the best product. Here are some points to help.

  1. Number Of Rooms/zones

We get this question all the time: How many zones can the best ductless air conditioner handle? One fact to remember is that ductless air conditioners are either single-zone or multi-zone (multi-split) in design. A single-zone setting comes with one outdoor unit and one indoor unit. If you are looking to cool two or more rooms, get a multiple zone unit that has one condenser and several indoor units, depending on your requirements. Under normal circumstances, one unit will cool one zone/room. The total square footage of the home will determine the number of BTUs you need to apply. More about BTU is in the next point.

  1. BTU/Power

Most manufacturers put the initials BTU on their units. Often, there will be a number before these letters. That’s where the focus should be. BTU simply means British Thermal Power, a reference to the amount of heat required to add 1°F one pound of water. We can safely say that the number of BTU on a ductless air conditioner is directly proportional to the size of space the a/c can cool down. Target the correct mini split BTU per square foot for your space by sizing the equipment. Generally, room sizes and BTUs relate according to the following table:

BTUsSpace Size (square feet)

  1. Unique Features

A mini-split air conditioner that does more than just cool the home is a good thing to have. Manufacturers know this secret, so they will add some extras that improve user experience and even save costs. Get an a/c with a programmable timer and you may never have to worry about unnecessary temperatures in the home even when you are away. For extra convenience, insist on remote-controlled equipment too, as it will help you adjust temperatures from the comfort of your couch. For remote control of the ductless air conditioner, Wi-Fi is a winner for me. Armed with an app and a smartphone, I am able to control my a/c system as long as it is within the network. I am looking to enable remote access by using cloud-based technology in the near future. This way I will be able to control the equipment via the internet. Some other interesting features that you may like include reusable air filters, temperature sensors, and allergen filters.

  1. Noise

We can all agree that air conditioners are generally noisy devices. By the time the equipment hits ten years, you have become accustomed to a wide range of noises- chatters, clicks, bangs, rattles, etc. It can actually become crazy. Many of us just get used to it and live with it. However, the truth of the matter is that a smoothly running ductless air conditioner shouldn’t make distracting noises. Its characteristic sound is understandable, but excessive noises should not be the order of the day. Sound is not controllable, but you can definitely do something about noise. Noise can affect comfort, so you want to look at this when buying. In some cases, perpetual noise may be harmful to health. Better ventilation systems and compressor technology are the main reasons most modern air conditioners are significantly quieter compared to those of yesteryears. If you are planning to get the ideal replacement for your buzzing old equipment, you must know how to tell if the new product is quiet enough.

Sound in these units is measured in decibels (dB) on a special scale. The lower the score on the scale, the quieter the product is. Our observation so far is that many buyers have problems figuring out the meaning of decibels. Manufacturers seem to have observed the same, as most of them use descriptions such as whisper-quiet, rustling, etc. I don’t think we can ever achieve 0 decibels. The best air conditioner I ever handled so far is 10 dB, and to be honest, it was unbelievably quiet.

  1. Aesthetics

Ductless air conditioners come in a wide range of indoor unit styles for different user preferences. Wall mounts, ceiling recessed and floor mount are some of the common ones. If you ask me, the recessed version is most attractive, but the basic ones not as much.  While these products offer quite some challenge to interior designers, there are many ways to maneuver around the problem. Recessing is one of the strategies, whereby the distance of the unit from the wall is minimized. False beams and recessed holes come in handy. Of course, you need to have some liberty of architectural space to use this method.

If space is tight, you can place the indoor unit above the window, possibly the only no man’s land available in a room. Just remember that areas around the window tend to be the most energy-inefficient. Far away from the window is always preferable for a mini-split system.

Painting the wall to match the unit is my favorite way of concealing the ductless air conditioner. Not only does the method conceal the gadget completely and swiftly, but it also simple. Make it even more enjoyable by buying a unit with one of your liked colors. Most models come in a variety of colors, so you should not scratch your head a lot here.

Other locations that impressed us are over the bed, over the doorway, over the bookcase, and inside the entertainment unit. What other ideas do you have?

  1. Energy Efficiency

Does the escalating energy bill give you goosebumps? Yes, no trick in the book is remaining for you, or so you believe. Save the resentment against the government and the power firm. There is one area that you probably have not tried yet- the air conditioner. Your 20-year old air conditioner could still be running smoothly, but it could be your thorn in the flesh.

Now, what do you do if the equipment is old? Very simple. Discard it.

One fact remains. Energy efficiency in air conditioners is not debatable. When you are selecting the best ductless air conditioners, I do not think you can afford to trade efficiency for any other aspect. Energy efficiency is all about the device using the least possible energy when cooling your space.

Heating and cooling devices are the biggest energy consumers in most homes. This simply means that the energy consumption of your ductless air conditioner can affect heavily on your total energy bills. You now realize how crucial it is to take your time in choosing the most energy efficient product.

Three ratings that feature prominently in air conditioners in regards to energy efficiency are:

  • Heating Seasonal Performance Factor (HSPF)

HSPF = Seasonal Heating Output (BTU) / Total Energy Usage (watt-hours)

  • Energy Efficiency Ratio/Rating (EER)

EER = Cooling Output/ Total Energy Usage (watts)

  • Seasonal Energy Efficiency Ratio/Rating (SEER)

SEER = Cooling Output / Total Energy Consumption (in a particular season)

We consider the SEER the best way to determine the efficiency of a ductless air conditioner, where a minimum of 13.0 SEER is recommended in the United States.

  1. Price

The price of a typical ductless air conditioner is usually higher compared to conventional that of solutions, simply because this is still a new technology. You could compare it to solar modules and light emitting diodes (LEDs). The inverter technology in most of the current units is probably the reason the upfront cost tends to be high. However, the high cost is nothing compared to the savings made once the unit is installed.

The fact that ductless air conditioners lack ducts is alone a source of money savings in installation, compared to central air systems. Energy savings are also possible because the air travels less distance for the same reason. Getting the device from the store will set you back in the range of $1,800. That is just for one unit. Installation should not last more than two hours, with the cost for an hour being about $30. Taking the total labor cost to be about $100, the entire cost for the system should not go beyond $4,000 for a home with four zones. This is a far better deal compared to central air conditioner installations, whose minimum cost is $5,000 in most areas.

  1. Longevity

One of the most abiding questions for buyers of air conditioning equipment is, How many years will it last. According to experts in this field, a wide range of factors determines the longevity of a system. Proximity to pollutants, daily run-time, maintenance level, and repairs are some of those factors. Don’t forget that your usage behavior can have a considerable effect on the lifespan of your unit. For instance, constantly changing the thermostat has serious ramifications on the integrity of the unit. Other contributors you need to take care of include personal care products, air fresheners, and some laundry items, as they volatile organic compounds (VOCs) to the atmosphere. You also need to be extra vigilant if you are living near the coastline.

I will tell you this; even the most experienced contractor may be unable to give the exact longevity of a ductless air conditioner. To complicate the matter, customer expectations tend to different, especially depending on generations. For instance, older users believe that the product should last longer, say up to 20 years. Younger ones are used to replacing items regularly, so they will not mind a unit lasting10 years. Installers must balance these kinds of expectations.

Who knows the truth then? The manufacturer often has expectations that are more clear-cut. We consider the warranties offered by reputable manufacturers including Mitsubishi Electric and LG to be quite impressive. All you need is to hire a certified contractor and some of the components will be warranted for over a decade.
