Ranked as a number one bestseller on Amazon, the Senville SENL-09CD mini split air conditioner has proven to be one of the most popular ductless air conditioners around, and for pretty good reason. It’s basically a 4-in-1 mini split air conditioner that guarantees super quiet operation, and is ideal for your living room, bedroom, or even your garage. You’ll have to spend significantly more than you would on a window or a portable unit, but for a unit that features built-in air conditioning, a dehumidifier, a fan, and a turbo function, the expense will be more than worthwhile. Go ahead and get to the end of this review to find out why it’s considered the best ductless mini-split air conditioner in the market right now. You may want to also compare it with other top-performing air conditioners.

Why We Like It – Senville Mini Split

The SENL 09CD Senville Mini Split HVAC system is one of the most popular air conditioners on the market. It’s available in a wide range of different BTUs, and is easy to install if you consider yourself a handyman. If you wanted a smart unit, you can still transform this one using the Sensibo Sky Smart Air Conditioner Controller.

  • Cooling range of up to 450 feet
  • Airflow Efficiency of up to 256 Cubic Feet per minute
  • 2 Year Warranty on Parts, 5 Year Warranty on Compressor
  • Only works with a Senville thermostat


The Senville 09 CD model is a 9000 BTU air conditioner that’s ideal for rooms of up to 450 square feet in size. However, the Rollibot portable A/C can cool 650 sq. ft! For a unit that more than doubles that capacity, check out the Senville Mini Split SENA 18MO-209 model. The Senville 09 CD model also features a heat pump that you can use to heat your space in the cold season, and a turbo function that increases its airflow to a maximum of 265 cubic feet per minute. Just like the Pioneer mini-split, the air conditioner also comes with a 16-inch installation kit, a communication cable, and a remote control for easier operation.

Energy Efficiency

With a SEER rating of 19, the Senville 09CD is not as energy efficient as the DIY-12-HP-115B25 MRCOOL mini-split, but it also won’t have your electricity bill balloon too much, as Senville air conditioners are known for their high energy efficiency. The air conditioner has a heat pump that’s also capable of heating your room for up to 5 degrees celsius, and with a noise level that only gets to 25 decibels, you’ll be guaranteed a sound sleep at night without any disruption. It’s much quieter than the SereneLife portable conditioner/dehumidifier.


The Senville 09CD has removable filters that you can take out to wash, and since they’re also reusable, you’ll be able to enjoy using them for a while before you need to get new ones. The Daikin 12000 BTU mini split air conditioner also has the same removable filters, so you’ll be able to have an easy time whenever you’re doing maintenance.


The Senville Mini Split air conditioner may not feature an energy star rating, but it’s still pretty efficient, and also features 2-way directional airflow, with oscillating louvers. This keeps whatever room the unit is in evenly conditioned, and thanks to an automatic switch mode, the air conditioner will be able to switch between cooling, heating, or drying the air.


The extent of warranty coverage that you’ll get with the SENL-09CD air conditioner is very difficult to find with other manufacturers. With it, you’ll get up to 2-year coverage on parts, as well as a 5-year coverage on the compressor.

Senville Mini Split Wrap Up

With a timer built-in, you’ll be able to program the conditioner to turn on or off during certain different times of the day, and with the different models that you’ll be able to pick and choose, there’s a wide range of variety to fit your specific room size and cooling requirements.
