I got this item because the previous one I had stopped working after 4 years in service. It was an LG which was awful in my opinion due to its low cooling capacity. This Senville LETO Series Mini Split Air Conditioner came in a nicely packed box with manuals and necessary tools included to install it into your window or wall. It cools well even on highest setting, but never freezes up like my last unit did! Not only that, but there are four different modes you can select from depending on what you need. Overall, this unit does everything I expected of it – it cools down my room, has a variety of modes, and is also whisper quiet!

The only thing I don’t like about this product is how loud it can be… It’s not as quiet as other models out there which means you’ll have to lower your TV volume every time you use it or place it in a well insulated room. Other than that, though, everything else has been working as expected!

Buying Guide – Things to consider before buying mini split air conditioners:

Size of room:

If you want to cool down a larger space than you should probably invest in a more powerful and, therefore, more expensive air conditioner.


The things you get for the price is almost always worth it even if an air conditioner is a bit pricier than others. After all, paying $1000 extra might save your life by keeping your house cool on blisteringly hot summer days.

Energy efficiency:

If the main purpose of installing an air-conditioning machine in your living space is saving money then make sure that the energy consumption rating of the one(s) you’re interested in is high enough; otherwise it’d be better to reconsider your choices or buy something cheaper and less powerful (don’t worry, high rated split air conditioners hardly ever drive up your energy bills).


This is something that not everyone is worried about but if you’re living in a cramped area such as an apartment, condo building or duplex then it’s important to consider if the mini split air conditioner will be too noisy . It might even be illegal for some units to operate past a certain hour so make sure you check with your local laws and regulations before buying any one.


If you want the installation process of the unit you’ll buy to go as smoothly as possible and without causing damage to either yourself or your property then choose a model that requires little-to-no drilling holes from outside into walls (screen and ductwork) and that has a small number of parts/steps you need to assemble inside. Also, pay attention to the weight capacity of your floors since air conditioners are usually quite heavy.


Look for a unit with remote control, temperature adjustment buttons, an LED display to check the current settings, timer(s) and modes suited for your needs. Some air conditioners also come equipped with special filters or other extra features that you might need/want in the future.

Energy Star Rating:

This is very important since most states have laws regarding energy usage by household appliances – there are even some counties where out of all appliances it’s only legal to use Energy Star rated products . That said, if you’re living in one of those places make sure that all units you’re considering buying have a high enough Energy Star rating so as not to endanger yourself and others. It’s also worth considering the Energy Star rating of the unit if your main goal is to reduce energy bills.

Ease of Operation:

Make sure that you can easily control the AC (with buttons or remote; it’s also important that they’re clear and not too small) but also that the machine is easy to use in general (this includes an option to change/manage settings, modes, etc through a home automation system like SmartThings).

Automatic Shut Off Timer:  

This is another feature which might be irrelevant for some people but many find extremely useful when trying to cut costs – simply turn on this timer so that the air conditioner shuts off automatically when you fall asleep. This will prevent massive losses when having to use an AC overnight or when going away for a few days.

Noise Level:

Many split system air conditioners come with a compressor located outside and some even have an extra fan installed on the exterior to help dissipate heat. This not only makes them loud (the more powerful ones) but also keeps you from enjoying your time at home if it’s too hot outside. Try to go for units that don’t sound like a jet engine is running in your living room .

Some Tips:

1. For even more savings consider installing the unit on your water heater. If it’s rated for the amount of power you’ll be using then this is certainly an option to look into.

2. Make sure that all rooms you want to cool are within 30 feet (9 meters) max of the closest vent – too far away and they won’t get cooled properly; too close and there might be a risk of overcooling some areas.

3. Don’t forget about window installation kits if that’s how you want your unit to be mounted (also make sure they’re compatible with the model/make of split system air conditioner you decide upon).    

4. If possible try out different units in-person (preferably one that’s already installed in a house/building) before purchasing – this will not only let you see how compatible your HVAC system is but also give you an idea of the noise levels.

5. Read reviews online to make sure other people are happy with their purchase and don’t forget to take into account any problems they might have had. This way you’ll know which models are worth considering buying or whether it would be better to keep searching for something better/different .

6. Finally, avoid cheap models since these almost always end up breaking down right away (poor design) or not lasting long enough (cheap parts). Instead go for more expensive air conditioners since these usually offer much better value overall so even if they’re more expensive upfront they’ll end up saving you money in the long run.

7. Make sure that the machine has at least a 6 month warranty – anything less is basically not worth considering since it means you won’t be able to get any repairs right away.

Q: What exactly is a split-system air conditioner?

A: As the name suggests, it’s an air conditioner that comes in two main parts (the compressor and the evaporator) generally located in different locations. That said, there are also dual hinged models out there which stay together even when they’re used separately (one part remains somewhere else to cool something else).

Q: Are window mounting kits free or do I have to pay for them?

A: While these vary based on the particular model you buy, generally installation kits are included with most machine purchases. If not then just consider this added savings/value since looking into these can cost anywhere from $25-$400+ depending on what you specifically need.

Q: Do split-system air conditioners really save money?

A: Yes, especially compared to window mounts which are slow, inefficient and hard to install.

Q: How many watts/amps will my unit use?

A: This is something you should ask the manufacturer directly since they’ll give you the most accurate answer based on the model of your machine (there are also online calculators but these are rarely correct).

Q: What’s the best place for my AC?

A: If you’ve got enough space then the basement is always a good option (it does require some extra work) but other than that any other room in your home should be fine. As for whether to keep it outside or inside – this depends on how much noise you can live with (a window unit will certainly make more noise but keeps you away from direct hot air while an indoor AC will barely be noticeable).

Q: Is there anything I need to know about installation?

A: Yes, make sure that all parts are included and do not damage the machine before installation (the seller should let you exchange if something goes wrong or at least refund part of your money). Once everything arrives then check out step by step instructions/videos online so you don’t end up damaging your AC and voiding the warranty (whichever is applicable).

Q: Can I buy a used/refurbished air conditioner?

A: Yes, while these do not come with the same warranty/guarantees as new ones they can still be quite valuable even if they’ve been used. Some people might want to upgrade their current unit or simply install it in another room of their home – make sure to research this before purchasing though since these aren’t always easy to find.

Q: Are there any benefits of a dual hinged air conditioner?

A: They stay together even when they’re used separately (one is at the backyard while another one is in your living room for example) but since they don’t have to be moved all the time this saves you time/effort.

Q: Where are split-system air conditioners made?

A: This varies based on the brand, some manufacturers might use locally made parts which makes them more efficient but others might rely on imported materials which can make them less reliable. Either way, remember that you should only go for models from trusted brands, preferably those who offer prolonged warranties/guarantees.

Q: Is it better to go for a window mounted or split-system air conditioner?

A: Well, this is one of those questions that can’t be answered with just one answer since there are pros and cons both ways. For example, the only benefit of an indoor AC is that you’ll barely hear it while the main advantage of a window mount is its efficiency plus the fact that it won’t heat up your room (meaning you can leave doors open while still enjoying fresh air).

On top of these major differences there’s also pricing/warranties/installation to consider so make sure to weigh everything before making your final decision.  Lastly, if at any point you feel unsure about something then don’t hesitate to ask extra questions since this is your money and safety on the line (you wouldn’t want certain parts/warranties to be missing after investing all that time and effort).

Q: What should I look for when buying a split-system air conditioner?

A: Well, first you need to make sure that everything’s included. If there are any scratches or dents then just check these out prior to purchase and opt out if necessary. As far as installation goes then you might want to call local contractors if possible so you can compare prices but also know exactly what will be included in the process (some companies include free shipping while others might not).

Q: How much does it cost to install a split-system air conditioner?

A: This will depend on the company you’re dealing with, if you were to hire a local contractor then this is going to cost anywhere from 50 to 100 dollars. However, some companies might have installation included in their prices which can save you both time and money in the long run so make sure to check out all of your options prior to purchasing an AC.

Q: Should I install a split-system air conditioner outside or inside?

A: Well, when it comes down to it most people just choose indoor units since they’re easier/faster to install while outdoor models require assistance from professional contractors (who usually add these into their larger projects). If at any point you need more help then contact companies like .

Q: What is a programmable thermostat?

A: Well, while some people might say that these only work for window ACs they’re actually useful for split-system models as well since you can add them inside your home to make sure that everything’s working properly (this way the unit doesn’t have to run on its own 24 hours a day). You can also set up certain times when you’d like an air conditioner to turn off and on so it won’t randomly heat or cool your room at strange times of the day/night.

Q: How long should I expect my air conditioner to last?

A: This will differ based on how often it’s used, the models you’ve invested in and if they’re installed correctly. If your indoor AC isn’t running at optimal levels then this will reduce how long it lasts before needing repairs/replacement plus if their was an error when installing them then you might be dealing with this for a few months (which is why you should only trust local construction companies for installation)

Q: Can I cool my entire home with a split-system air conditioner?

A: Yes, but remember that these are designed to run on a single room at a time meaning that they won’t affect the other rooms in your house. In fact, some people use multiple indoor ACs to get each area of their homes up to temperature which also prevents less air from seeping out while the unit is in use.

Q: What should I do if my air conditioner makes a strange sound?

A: Well, there are usually signs that indicate when something’s wrong such as high-pitched or low-pitched noises (which means that different parts might be breaking down). If at any point you feel unsure about what to do then call an expert since they’ll know exactly how to fix this and prevent it from happening again in the future.


Before making a purchase it’s important to weigh all of your options so you can choose the right split-system AC for your home plus know what to expect during installation/overall usage. If ever in doubt then feel free to contact local companies for assistance with either one of these tasks. We hope you find this information helpful and can make an informed decision before purchasing one of these units.
