A mini-split heat pump system is one of the best solutions to employ if you want to be able to individually control the temperatures in different rooms within your office building or household. With it, you won’t need to install any ducts, so you’re going to have a home or office that looks great without any visible connections made between the units. If you’re moving away from a portable or a window-installed air conditioner, deciding on the best ductless mini-split air conditioner for you may be quite challenging. This is true, especially if you don’t know how to install a ductless split air conditioner. To help even things out, here’s one that we think you’ll find to be up to task – the SENA-18MO-209 Senville unit. Read on to the end of this review to know more about its features and also know how it compares to top-tier air conditioners.

Why We Like It – Senville Mini Split

If you’ve been looking for an HVAC system that’ll be able to fully take care of your air conditioning needs, then you really ought to consider the Senville Mini Split air conditioner. It’s got 4 functions built-in, and uses inverter technology for more efficient functioning. That is similar to its cousin the Senville Mini Split SENL-09CD model which is also a 4-in-1 model.

  • Use of Inverter technology reduces energy consumption
  • High SEER rating of 22
  • Quiet operation
  • Mounting brackets of the outside units have to be purchased separately


Performance-wise, the Senville SENA 18MO-209 ductless mini-split air conditioner is very much a capable AC unit, as it boasts of an 18000 BTU rating, which makes it perfect for any room that’s 750 to 1250 square feet in size. This is a lot larger than the 100 to 450 square feet room size that the Senville SENL-09CD is capable of handling. It’s also about four times larger than the capacity of the SereneLife Portable Air Conditioner.

Energy Efficiency

The Senville mini split air conditioner has an impressive SEER rating of 25, placing it among the minority of mini split air conditioners that has such a high level of energy efficiency. This means that your electricity won’t rise as much as it would if you’re using the WYSO 12A-19 Pioneer mini split air conditioner, which has got a SEER rating of 19. The air conditioner also happens to be energy star certified, and this means that it meets the energy efficiency criteria certified by the US department of energy.


Senville mini splits are quite great at filtering out any harmful odor or excess humidity from the air, leaving you with a room that smells fresh and is pleasant to be in. Just like the Daikin 12000 BTU mini split AC, It’s got removable filters, so you should be able to take them out and wash them whenever you need to. Operation is also whisper-quiet, so you shouldn’t expect the Senville mini system to wake you up in the middle of your sleep. 


This Senville mini-split system is made of solid materials that guarantee a long period of use. It’s got a 2-year warranty on its parts, and a 7-year warranty that covers the compressor. Installing it is also not very difficult, but if you’ve never dealt with an HVAC system before, try and make sure that you get hold of a qualified technician to do the installation for you.


This particular Senville mini split air system relies on inverter technology which controls the speed of the motor, and this is far more efficient in terms of energy consumption compared to the technology that you’ll find in older models. Apart from air conditioning, this Senville unit is also capable of heating your room since it’s got a heat pump built-in. It’ll also be able to dehumidify the air, and adequately circulate fresh air within a room thanks to its fan. This is great, except if your Senville air conditioner/heater isn’t working. You’ll need to call in the professionals for help. We wish there was an app built for it like the DIY-12-HP-115B25 MRCOOL mini split conditioner, but even without, its remote control makes it very easy to operate.

Senville Mini Split Wrap Up

The air quality of your space is a very important aspect especially if there is where you spend most of your time, and you’ll need to pay attention to it if you want to enjoy maximum comfort. The SENA-18MO-209 Senville AC outdoor and indoor unit will make sure that your environment remains fresh, and with the remote control that it comes with, you’ll be able to conveniently control the condition of any room regardless of wherever in your house or office you may be.
