Benefits of Using Ductless Mini-Split AC System
The benefits of using the best ductless mini-split air conditioning system include but aren’t restricted to just the following:
Ductless mini-split AC systems require nothing more than wall mounting and electrical access. These can be installed at any location – new or old construction, apartments, condominiums, etc. Temperature control is allowed for individual areas as compared to one standard temperature setting in duct-based systems. You can fit a ductless unit even in buildings that still contain ducted units.
2. Easy Management
The system is very much manageable, unlike the duct units. Cooling is directly passed onto the rooms. Traditional systems are quite rigid.
3. Aesthetic Value
The best part of having installed a ductless air conditioner is how it remains nearly invisible. Plus they are quieter than ducted systems which makes your ambiance peaceful.
4. Multiple Zone Handling
There are certain models available on Amazon where a single compressor can hold up to four different indoor units for convenient zoning. Of course, the rooms would have their thermostats – but you just condition the rooms and that’s it!
Apart from offering a flexible solution, the best mini-split air conditioners are cost-effective and bring down the utility cost to a manageable level. These units are smaller in size, lead to lesser leakage, and hence consume less energy to maintain the overall efficiency for a much longer time. Such a system allows you to create specific zones to control the climates especially for the rooms that aren’t occupied i.e. shut the cooling/ heating for these rooms.
6. Complete Temperature Control
Having a mini-split AC system helps you maintain a customized temperature for each room as opposed to central cooling or heating. This ensures complete charge over the heating or cooling settings via remote or timer controls.
7. Improved Air Quality
It is no secret how sometimes the indoor environment can be more toxic than how it is outdoors. Talking of the traditional HVAC systems, ducts need professional cleaning that too regularly. Else, they can leave behind harmful allergens which are dangerous for humans as well as animal health in the long run. However, the best ductless mini-split AC is quite the opposite. Ductless operation is cleaner and produces significantly less dust or bacteria.
8. Reduced Carbon Emissions
Talking of carbon emissions, the best mini-split air conditioners follow the energy guidelines that not only help you save on your bills but also reduce your carbon footprint. They put comparatively less exertion on environmental health – all thanks to the refrigerants it makes use of which is known to have zero ozone depletion potential. So, till the time the unit is functional, it will be environmentally friendly (if it’s federal government approved) and keep providing consistency.
9. Quick & Easy To Install
The larger the system, the tougher the installation, as well as the maintenance, gets. This is why the ductless mini-split air conditioners are less invasive and get operational in as little as 1 day. You do not have to worry about a lot of ductwork happening around or reconstructing the walls/ roof. There are just a few smaller pipes and absolutely no loss of storage.
10. Acts As A Heater
The heating capability of the best mini-split air conditioners enables the unit to also act as a heater during winter to keep the environment warm.
11. Quiet Operation
As opposed to the ducted or central units, mini-splits are pretty much noise-free. You may hardly hear any sound when standing next to the unit. They operate at minimum vibrations or noise.
Heat Pump/ Ductless Vs Normal AC
To be honest, there hardly are any people who know what ductless mini-splits are – because they are all air conditioners, and aren’t all the ACs supposed to fit in the window, be mounted on a wall, or work centrally?
To start with, let me lay down facts that yes, these aren’t as popular as the traditional duct systems however these are now gaining popularity because of their efficiency and flexibility. These can cool multiple zones, be efficient at what they are designed for, and are commonly called just split ACs. I hope now you can recollect what I’ve been talking about.
These systems have an exterior (compressor) unit which carries out the intensive work. And there’s an indoor unit that produces the cool air – real work. These do not require ducts for this purpose, rather they just need drain lines along with a strong connection between the evaporator as well as the condenser. That’s it!
The best mini-split air conditioners operate with minimum noise, need professional technicians for the installation process, and match your room’s aesthetics pretty well.
Choosing The Best Ductless Mini-Split AC System: Buying Guide
There are several factors to consider while purchasing the best mini-split air conditioners. Ductless ACs are getting popular and so must the knowledge be. Therefore, here’s a buying guide to help you make an informed purchase and get home the best ductless mini-split:
The primary consideration must be the purpose for which you want to buy a mini-split air conditioner. Is it just for cooling or is it for heating plus cooling? Make sure you first understand what you want to buy it for and then move forward with the purchase decision.
For most of us, budget is the number 1 priority. No matter what, several times our purchases depend on the affordability factor. The same is with buying the best mini-split air conditioners. So, it’s both ways – either you have a pre-defined budget after which you can check what all features you get under the same or first list down the essential features you are looking for and then accordingly adjust your expenditure.
A single-zone system can cost you anywhere around $2000 – $3000 including the kit as well as the installation. If you are willing to invest in such a high-quality product – mini-split systems are for you! However, you can get things done at a much lower cost from a nearby hardware guy, but there’s no quality assurance in that case.
This is the measurement of the cooling capacity of the air conditioner. So for instance, 1 ton will attract 12,000 BTUs / hour from a room. In mini-split ductless AC systems, you can get up to 4 tons. Therefore, according to your usage and preference, you may decide on the tonnage to go for.
British Thermal Units directly associate with the unit’s ability to produce cool air, in fact, the amount it can. So, this is the mechanism – the more zones you have, the higher BTUs come into working. These are required to efficiently cool your space/ zone.
5. Zone Design
Let’s make it simple – this factor concerns selecting either a single-zone or a multi-zone design. Single-zone units cool only a single room whereas multi-zones can prove effective for several zones. So, be very careful and analyze the situation. A quick suggestion – it can be ideal if you go for a multi-zone system which will make it easier for you to make zones later if in case you aren’t sure of what to do. At least that’s better than remaining dissatisfied.
6. Multiple Coverage
Some of the systems remain to be a single-room affair. However, there also are outdoor units capable of supplying the refrigerant to around 9 individual indoor units at the same time.
7. Sound Level
The best mini-split air conditioners are usually much quieter than their environment. The range is measured in decibels and it varies from 20 to 60+ decibels. So, anything that’s under 40 dB would do the job for you.
8. Seasonal Energy Efficiency Ratio (SEER) Rating
The SEER rating is the cooling output divided by the energy input during a cooling season resulting in how energy efficient a unit is. Therefore, the higher the SEER rating more the savings and the lesser the utility bills. Modern mini-split air conditioners can have a SEER rating of 13 to 22 or more. 13 is the federal minimum as well as much cheaper whereas 21 SEER air conditioners would cost you more. But, the minimum or standard SEER rating can differ from region to region. So, discretely choose the SEER rating – 16 to 19.9, 20 to 22.9, or 23+.
9. Types of Indoor Components
There are different types of indoor units available namely wall-mounted, ceiling-recessed, floor mounted, and concealed. Here’s what you need to know about these:
Wall Mounted –
- Commonly used
- Easy installation and affordable option
- Suitable for single rooms
- 26 dB operational ability
Ceiling Recessed –
- K.A. cassette
- Inserted into the ceiling
- Can send cool air in all the four directions
- Great for larger floor plans
- 36 dB operational ability
Floor Mounted –
- Sits near the floor
- Easy maintenance
- Directs air to the top
- 35 dB operational ability
- Least obtrusive
- Only the grill is visible in the room
- 30 dB operational ability
- Sits above a soffit
10. Additional Features
Sensors: Some brands manufacture units that specifically ramp up when you enter and turn down the moment you leave. Cool feature, isn’t it?
Wireless connectivity: Certain systems come with Wi-Fi connectivity so you can set them up on your smartphone. It stays in control no matter where you are or where you go!
The warranty coverage may depend on and range from 5 years to 10 years as per the manufacturer of the system. So, make sure to check that beforehand and avoid any troubles at a later stage. However, brands do claim an equipment’s life to be around 10 to 15 years but that again depends upon the usage and the surrounding conditions.

4. Pioneer (WYS009AMFI17RL) Mini Split (9,000 BTU) Ductless Mini Split AC Systems Review
It is the #1 best seller on Amazon as of now. The Pioneer ductless mini-split is a 9000 BTU unit that also comes in several other sizes. This is an all-in-one unit that offers heating, cooling, ventilation as well as de-humidification. It maintains the performance level along with the user’s comfort and efficiency. If you’re looking for a single-zone heating or cooling solution, this is going to be one of your top choices. It offers year-long comfort and also helps you save significantly on your power bills.
The BTUs range from 9000 to 36,000 so you must choose the model accordingly. Plus the SEER rating is 17.0 so that is again great for the price it comes at. Talking of the outdoor section, it has a variable speed and metallic construction (no worries at all, it is electrostatic resistant). The wall bracket is sturdy and will hold the unit well. It has a superior design but somehow doesn’t feel too durable.
The installation process is easy if you are someone with the right HVAC tools. But, if you are a first-timer, there’s a whole set of equipment that you will have to separately invest in. That is the case with every other mini split air conditioner – you do require stuff such as a hammer, wrench, drill, leveler, vacuum pump, control wires, leakage detectors (soap solution or professional fluid), micron gauge, pipe cutter, ties, tapes and so much more. Just the mechanical aptitude will not make the process stress-free. You’ll have to have the basic as well as specialty set of tools to make it all work.

With year-round comfort, no leaky ducts, and easy installation, this Cooper and Hunter (CH12ACE230V) 12,000 BTU mini split air conditioner is a wise investment. It is perfect for the cooling as well as heating needs of a room. The installation is pretty easy and the only drawback I find is how the product is relatively newer in the race. It offers a superior performance along with a noiseless operation.
The manufacturer puts out a legal disclaimer that the customer must go for a professional installation to set up the indoor or outdoor unit, vacuum the lines, check for leakage, and also ensure the refrigerant levels. But, several people have done it themselves and the process is smooth. Anyway, despite being an affordable mini-split, the installation costs will just add to the entire thing. Its inverter technology helps bring down utility bills and not to forget auto resets which are again convenient. More the people have used this unit, the more are they satisfied with the after-sales services along with the overall performance of the air conditioner. It is super quiet, instructions are detailed really nicely, and is, therefore, a recommended unit.
- Automatic operation.
- 22 SEER ratings.
- 16 feet installation kit.

Distribution of the air is fairly even and the system works in four different modes – fan, cooling, heating as well as dehumidification.
If you check out the product on Amazon, there are hardly any negative reviews or complaints that you might find. Although it’s comparatively a newer product in the market it caters to a low-cost budget, offers durable built quality, and is energy efficient. Amazon delivery is as promised but the installation might call for professional hands. Though for some buyers, the process has been stress-free, you might not want to risk such an expensive purchase in case the installation doesn’t go as planned. So yeah, professional HVAC fittings would definitely add up to the final costs making even one of the most affordable units somewhat pricey. But well, that’s the case with every unit that you can fit by an expert. But, in terms of performance, you won’t really face any issues – you need cooling, it does that, you need heating, it does that too! Not just that, some of the buyers who have made their first purchase plan on buying more of these Klimaire units for other rooms in the house too.
- Automatic self-clean function.

Installation instructions are pretty extensive so you will not face any difficulty. The construction quality is absolutely sturdy and Amazon takes complete care of the unit in terms of packaging since it’s a large product to ship and also fragile. The unit will be a blessing with the right installation and regular maintenance. However, you must always take care of the warranty/ guarantee details when investing in something this big. So, you might want to check if the warranty validates DIY installation or voids the same. For more deets and customer reviews, check out the product on Amazon to make an informed purchase.

Talking of the product’s durability, it is unmatched. Other exciting additional features such as sleep mode, washable filters, fan speed, and timer settings would want you to consider buying this unit. So, if you are still using the traditional air conditioning system, it is time for a change. Replace the older unit with this one and you will not regret even a bit. The unit is pretty much affordable and is equipped with the ability to individually control specific zone settings. The only thing I don’t like about this model is how it comes with several pieces of equipment for the installation process and this can, for some people, get really confusing.

What is Ductless Mini-Split AC System?
To understand what a ductless mini-split AC system is, know what primarily differentiates a traditional air conditioning system from a mini-split system – it is the ductwork. The former has it and the latter does not.
Another major difference is the compressor. As compared to the window or other units, the noisiest part of this system (compressor) remains outdoors in a separate unit.
Traditional systems aren’t suitable for everyone’s needs. Whereas, ductless heating and cooling units are more flexible and also quite popular now. In simple words, ductless mini-split AC systems do not require full-size ductwork to function in your home. Their functioning is pretty different from central air conditioning systems. The central systems produce the cooling air from a single point and dispense the same via larger ducts throughout the area. On the other hand, a ductless mini-split is designed to make use of an individual (comparatively small size) fan as well as an evaporator for every room.
Yet another obvious difference is how you can mount the unit anywhere on the wall at your convenience. It doesn’t have to necessarily fit into a window or go along the upper edges of the room like ducted units. This makes the system aesthetically more appealing and secure.
This provides better control over the temperature settings. Warmer rooms can work on separately adjusted temperature settings. And, for the areas that aren’t in much use, you can turn off the system and save more energy. The ductless mini-split units function quietly, are energy efficient, and are more adaptable. Their installation is cheaper, easier (pretty much DIY), and not at all time-consuming. These are more functional in smaller individual spaces due to the absence of any ductwork.
How Ductless Mini-Split AC System Works?
Let’s first look at the working of a traditional system – with the help of a blower, a conventional unit sucks the air from inside the room and takes it back to the primary blower. The air is then pushed through the evaporator removing the heat. The cooled air is continuously pushed out of the system, into the ducts and then to the vents. So basically, air from the entire household (or commercial property) is channeled towards the main unit, is cooled, and then sent back to various areas in the property through the duct.
Coming to the functioning of a mini-split system partially works the same way – instead of pumping the air through the duct (in the attic or basement), it works in individual rooms to push the air through the evaporator. It pulls the air from the room it is fixed in, cools the same, and blows it back. The air just doesn’t have to leave the room it is in. The refrigerant is pumped into the individual indoor unit which functions as a mini air handler to deliver cool air in its particular zone whenever required. Due to the absence of ducts, there’s no leakage (heat, air, cooling or pressure) which doesn’t undermine the efficiency of the system.
Working In Detail of the Mini-Split AC System
The refrigerant running through the evaporator coils absorbs the warm air from the room’s environment and gets it to the outdoor unit. The indoor unit as the name suggests remains inside the room and eliminates the need for having large size ducts. In case one wants to cool the entire home similar to a ducted unit, you may connect the multiple indoor units to that one outdoor unit and provide cooling/ heating overall.
Mostly all AC systems require the same kind of outdoor elements. Even here, the outdoor unit is where the refrigerant dumps the hot air pulled from inside of the rooms. Cold refrigerant produces cool indoor air. There’s no complexity during the installation process – just a 3-inch hole through the wall to house the necessary wiring along with the drainage line between the two units. That’s all!
How To Install Ductless Mini-Split ACs?
Well, I wouldn’t get into any comprehensive details of how to install a ductless mini-split AC. I’d rather give an overview of how it can be done easily – the rest you can Google out as per the particular model you have and if at all the manufacturer advises going for DIY installation. These steps are just supplemental aid and are not supposed to replace the professional/ manufacturer’s instructions.
Things to keep in mind …
- Before installation, make sure it is a DIY unit
- The refrigerant lines need to be re-charged
- Thoroughly go through the instructions manual
- Check the warranty or guarantee details
Installation: Indoor Unit
Step 1: Gather the required tools such as a drill, wrench, hole saw, leveler, tape, screws, etc.
Step 2: Unbox the entire unit very carefully.
Step 3: Once everything’s out and clear, start to work on assembling the wall mount first since that’s easier.
Step 4: Start the installation at least 6 feet above the floor and also make sure this wall is close to the outside area as well.
Step 5: Here comes the assembly of the inside unit. After this is done, you can set it onto the metal bracket, screw it securely and move on to the next part.
Step 6: Drill out a hole (ideally 2 to 3 inches in size) for drainage accommodation along with routing the refrigerant bundle. Check the manual on how it says to attach the control wiring.
Step 7: Get the piping and tubes pushed right through the hole you drilled out and secure everything tightly.
Installation: Outdoor Unit
Step 1: Coming to the outside system, start working on mounting the outside unit. Make use of the levelers while placing the unit with precision. You can set it up on the rooftop or anywhere right on the outer side of the indoor unit.
Step 2: Connect the electricals. Maybe you can call a qualified technician to do so if that’s not your department. It’s not worth taking a risk. But, if you are skilled to do so, voila!
Step 3: Also, get to the refrigerant lines (not to lose nor too secure) and check for any leaks.
Make sure to install any other required stuff like the Wi-Fi adapter, filters, or remote mount, etc. Once everything’s in place, test the unit.

Frequently Asked Questions for Ductless Mini-Split AC System: FAQs
Regarding the best ductless mini-split air conditioners, here are the frequently asked questions. I hope these help sort out your queries.
Q1.What size mini-split AC do I need?
There’s a standard sizing measurement that you can follow to know what size split AC you will require. Here’s what you need to know:
- 350 sq. ft. – 9,000 BTU
- 500 sq. ft. – 12,000 BTU
- 750 sq. ft. – 18,000 BTU
- 1000 sq. ft. – 24,000 BTU
- 1250 sq. ft. – 30,000 BTU
- 1500 sq. ft. – 36,000 BTU
This is an important factor to consider so you do not lose out on the unit’s efficiency as well as its durability.
Q2. Are mini-split AC energy efficient?
Mini-splits do not let out the cooled air from your room as compared to an estimated loss of 20-30% from the ducts due to leakage or poor connection. Leakage is the real problem and that brings down the system’s efficiency. The inverter-based compressors cater to individual needs rather than entirely shutting down the system. And, the startup in these units usually consumes a lot of energy which is quite the opposite in mini-split AC systems.
Q3.How long does mini-split AC last?
The average life is said to be around 10 to 15 years considering its maintenance and a lot of other factors. Other aspects that may help you know how well the unit is performing include the level of humidity, repairs made as of yet, of course, the age as well as the energy usage.
Q4.Does it stay on all the time?
A mini-split isn’t practically working 24 hours a day but it is designed to be able to run that long without any hindrance.
Q5.Where to buy a mini-split AC?
You can buy them online. To help you make an informed choice, I’ve detailed the best mini-split system reviews above. Make sure you refer to those before making a hefty investment.
Q6.Are these just for cooling purposes?
Not really. Most mini-split air conditioners are heat pumps which means they can both cool as well as heat the room. This kind of unit eliminates the need for having a separate heater.
Q7.How much would a mini-split AC system cost?
Well, the price of a mini-split AC system depends on various factors such as the brand you choose, tonnage of the system, SEER ratings, BTUs and number of evaporators or blower coils, etc. However, it can roughly cost you between $1000 and $3000 (even more in some cases). Depending upon factors such as the brand, tonnage, type of unit, SEER rating, etc., the cost may vary.
Q8.Are there any downsides to having ductless systems?
The only downside I see to ductless systems is their cost – in general, these cost more than centrally conditioned systems. However, for the latter, the cost does not include the price of ducts. The basic models can somewhat suit your budget but those units might not be too attractive or too efficient.
Q9.Who will do the installation work?
You need a professional for this kind of work. So, please do not get any technician that may do the job for just a few bucks. You can always check the manufacturer’s official website to pick from the list of experienced installers. If you are a qualified DIYer, then you can install it yourself.
Q10. Where is it best for the outdoor unit to stay?
The outdoor unit would perform well when under partial shade. Maybe under the deck would be an appropriate location – just make sure there’s enough airflow and area to carry out the maintenance jobs.
Q11. Where exactly do I install the indoor unit?
You can mount the indoor unit on the wall which is close to the outdoor unit. Why so? Because this way connecting the refrigerant lines gets much easier.
Q12. How long will the installation take?
Talking of ducts and ceiling units, these require more effort and are time-consuming. However, the best mini-split air conditioners take only around 4 to 5 hours (single wall-mounted unit) for the entire process to wind up.
Final Words for Ductless Mini-Split AC System…
