Things to Consider
Now that you’ve read through our ductless air conditioner reviews and seen some of the top ductless air conditioner models on the market, it’s time to take a closer look at what these units really are, how they work, what advantages they have to offer, and how you should go about choosing the very best A/C for your home. Read through our ductless air conditioner buying guide to learn more.
Benefits of an ac unit at home
First of all, you might be wondering if it’s really worth getting an A/C unit for your home. Well, when you start to see all of the different benefits an A/C unit can provide, the choice becomes a whole lot easier.
Cool Air – For starters, an A/C unit can, of course, help to cool your home down when the weather gets warm. This can be so beneficial, especially in warm and sunny areas.
For Asthma Sufferers – If you have anyone who suffers from asthma in the home, an air conditioner can make a difference. Studies have shown that by reducing the humidity, pollen, mold, and mildew levels in the home, A/C units can make life a lot safer for asthma sufferers.
For Allergy Sufferers – Just like with asthma sufferers, A/C units can also help to rid the air of allergens like pollen and mold, making the air cleaner and easier to breathe comfortably for anyone you know who suffers from allergies.
A Safer Home – With an A/C unit, you won’t need to leave your windows or doors open to let cool air into your property. This helps to make the place a lot safer and provide more peace of mind for every homeowner too.
Great For Exercise – If you like to work out at home or enjoy doing yoga and similar exercises in the comfort of your own property, having a cool, fresh space with good air circulation can really help to make every exercise session a lot more enjoyable.
Better Sleep – Science has proven many times that people sleep better in cooler conditions and it can be a lot harder to fall asleep when you’re all hot and sticky. A/C units can therefore greatly assist you in getting a good night’s sleep more often.
Fewer Insects – Air condition works wonders at keeping bugs and parasites out of your home. You get to keep your windows closed and many units are fitted with filters too that can stop bugs in their tracks, even reducing the risk of your dog or cat getting fleas.
How does ductless air conditioner work?
Ductless air conditioners, also known as mini split systems, work quite simply and copy most of the same functionality as a ducted A/C unit, but without the vents. Essentially, these units suck in warm air from around the home, absorb all the heat and moisture from that air, and then blow cool, fresh air back out around the room. Ducted A/C units send the cold air into ducts which flow around the house, while ductless. A/C units simply expel the air via vents on the unit itself.
Ductless vs ducted
If you’re thinking of investing in a unit like an LG mini split or Mitsubishi mini split, it’s first important to look at the differences between mini splits/ductless A/C units and ducted A/C units.
Ductless units are preferred by many people due to their lower prices, simple installation, flexible usage, easy maneuverability, lower energy costs, and the fact that they’re just much more convenient to use in general as you can install them wherever you like and use them to zonally cool down individual spaces, rather than wasting energy and money cooling down rooms you aren’t even using through a ducted system.
However, on the downside, when compared to ducted models, ductless units aren’t able to cool down such large spaces so easily and you can’t exactly hide their indoor units in the same way you can with a ducted model, so they will take up some of your living or wall space.
Features to consider while buying the best ductless air conditioner
If you’ve decided that a ductless air conditioner could make a great addition to your home, it’s important to not just dive right in and buy the first Samsung mini split or Pioneer mini split you find. Before choosing your model, you should think carefully about where and how you’re going to be using it and how much money you’d like to pay, as well as considering a variety of additional factors like the noise level, controls, warranty, dimensions, ease of installation, and more.
Consider the room space
One of the most important things to do before buying a ductless air conditioner or Sennville mini split is to think about where you’re going to be installing it. How big is the room? What’s the layout of the room? How powerful does your unit need to be in order to cool down the space? Ask yourself these questions and find a model that can provide the right answers.
All good A/C manufacturers test their units thoroughly to see how much cooling coverage they can provide, and some of the best A/C units out there are able to cool down very large living spaces. The Thermocore T322D-H224-9+12, for example, can cool down a space of up to 1,200 square feet, so is ideal for large, open-plan living areas, while other units are designed for much smaller spaces.
Another big factor to think about when buying a ductless air conditioner is how much noise it will make while in use. These units tend to have quite big fans inside that can get very loud at the highest settings, but the best manufacturers go to great lengths in order to keep the volume levels of their units quite low.
The Klimaire KSIV012-H119-S(W), for example, can function at a noise level of just 25 dB, while the Simply Modern Personal Mini Air Conditioner operates at just 35 dB, which is very quiet overall and won’t distract you or cause you and your family to have to talk any louder or turn the TV up to hear your favorite shows while the A/C does its thing.
You also need to consider what kind of control systems and settings are in place on your chosen unit, as this determines how easy it is to use and what kind of options you have in terms of turning it on and off, adjusting the fan speed, and more.
The Cooper & Hunter Air Conditioner, for example, is Wi-Fi ready and can hook up to your own internet router for easy wireless control, as well as offering 12 different fan speeds. Meanwhile, the boreal EQX12HPJ1SB ships with its own remote control and can also be controlled wirelessly by Android and iOS devices over Wi-Fi.
What is SEER?
SEER is another term you often see when talking about A/C units. It stands for seasonal energy efficiency ratio and it’s defined by the Air Conditioning, Heating, and Refrigeration Institute. In simple terms, the SSER rating of a unit tells us how energy efficient it is. The higher the rating, the more efficient the unit is. The Cooper & Hunter Air Conditioner has one of the best SEER ratings of any unit on our list.
Outdoor and indoor unit size
You should also think about the size and overall dimensions of any A/C unit before buying it, ensuring that you have enough space in your home to accommodate the unit and checking that you’re happy with the amount of space the unit will take up too.
The RolliCool Mini Split Quiet Ductless Air Conditioner is an example of a compact and nicely-sized model with small units that won’t take up too much space while still offering impressive performance. The Simple Modern Personal Mini Air Conditioner is also a very small device that is designed for personal use in a small space like a car or office.
In most cases, you’ll be able to install your ductless A/C unit on your own without the need for any professional help. However, some units are a lot easier to install than others, so it always helps to find one that won’t take too long to install or be too complicated. The Innovair Air Conditioner, for example, is reputed among users for its ease of installation.
Ideally, you’ll hope that your new A/C unit won’t encounter any technical issues, but there are cases when these models can have little faults or failures and require some repairs. This is where it can be so helpful to have a good guarantee or warranty policy to protect you. Many of the best manufacturers offer several years of coverage, and the Gree SAP12HP230V1A, for example, comes with a 5-year limited warranty, providing total peace of mind for five whole years.
You’ll need to clean and maintain your air conditioner over time if you want it to continue working perfectly for years to come, but some units make the cleaning process a lot easier than others. It helps to be able to unscrew and take apart different components of the unit quite easily and wipe it over with ease, and it’s even better when your unit ships with a self-cleaning feature, as seen on the Klimaire KSIV012-H119-S(W).
Don’t forget to think about your budget when buying a ductless air conditioner. These units can come with wildly different price tags, with some going above and beyond the $1,500 mark and others available for just a few hundred dollars or even under $50, like the Simply Modern Personal Mini Air Conditioner, for example.
Be sure to plan out how much you’d like to spend and find a model that matches your budget and needs. You don’t always need to buy the most expensive unit, as some of the more expensive options might be a little overpowered for your home. Equally, you don’t want to set your budget too low, as a cheap unit might be too weak to really provide the cooling effect you need.
Another key aspect to think about when buying a ductless air conditioner is its durability. Ideally, you want your unit to be able to last several years without encountering any issues, and these kinds of devices can be exposed to a range of dangers like dust and dirt building up inside, so durability is definitely a key factor to think about, especially if you’re investing a lot of money in a high-end unit like the boreal EQX12HPJ1SB.
It makes a lot of sense to try and find a very durable model, as this will save you a lot of money in the future. Instead of having to cover the costs of repairs and replacements, you’ll just be able to sit back, relax, and enjoy all the benefits of your air conditioner. We’ve included only the most durable models on our list, but we do remind you that it’s vital to clean and maintain your unit if you want it to last for a very long time.
One important thing to remember when it comes to ductless A/C units is that they need to be cleaned often and cleaned well in order to function at top capacity for the longest possible period. This is true of all models, except those with self-cleaning functionality like the Klimaire KSIV012-H119-S(W).
When it’s time to clean your A/C unit, be sure to switch it off and disconnect the power to minimize any risks. From there, you can wipe over the exterior with a simple water and soap solution, as well as potentially removing some of the outer shell in order to clean the interior components too.
Often, the manufacturer will include a step by step cleaning guide in the instruction manual, so we encourage you to read through the specific guide for your chosen model to get the best cleaning advice.
One of the many benefits of buying a ductless air conditioner unit like the Klimaire KSIV012-H119-S(W) is the fact that these appliances are often easier to install than their ducted counterparts. In many cases, you can actually install the unit on your own, simply by following the included instructions. The best ductless air conditioner models will always come with step by step instruction guides that you can follow to get your unit up and running in a matter of minutes, and many of them are very easy to install, especially if you have a little DIY experience. If you’re unsure about any aspect of the installation process or just want to err on the side of caution, you can also choose to call a professional to do it for you.
It’s absolutely essential to clean and maintain your air conditioner if you want it to work at top capacity each and every day and function flawlessly for years to come. A poorly maintained A/C unit can develop all kinds of faults and even break down over time, leading to big repair costs or even replacements for you to pay for. To maintain your A/C unit, be sure to check it over regularly, cleaning the outside, cleaning or replacing any filters according to the manufacturer’s instructions, and taking a close look at the various parts to ensure that no dust or debris is building up inside.
HVAC is a term you see quite a lot when looking at air conditioners, and it can be quite a confusing acronym at first for those who aren’t familiar with it. Simply put, HVAC stands for Heating, Ventilation, and Air Conditioning. It’s basically a term to refer to all the different systems that move air in, out, and around the home. It encompasses all the different devices, units, and appliances in your home that help to control the airflow and temperature, including things like radiators and air conditioning units. So the next time you see or hear someone using the term HVAC, you’ll know it’s basically just talking about the ventilation, heating, and air flow around a building.
Overall, our top rated ductless air conditioner and winner of our Editor’s Choice award is the Klimaire KSIV012-H119-S(W). Designed and constructed to the highest possible standard, this is one of the most impressive A/C units around. It can cool down large areas in a matter of minutes and even has the ability to keep itself clean.
