If you lack the space for a window unit, Mini-splits work wonderfully with the CoolBot and are a great option. International customers often find these units to be more available and affordable. In the US, mini-splits can cost twice as much as a window unit, but they're also more efficient. Consumers may not notice big savings since the CoolBot systems themselves use so little electricity.
*Panasonic, Midea, Senville, Electrolux and Mitsubishi Mr. Slims have been difficult to work with so best to avoid them. Watch out for re-branded air conditioners with these compressors. Some mini-splits have very short temperature sensor that can be found right on the circuit board of the air conditioner.
Ask the mini-split manufacturer what is the lowest OUTSIDE air temperature the unit will function in and compare that with your climate. Obviously, even if the CoolBot works perfectly with your air conditioner, if it's a brand that stops working when the outside temperatures fall below 40F (4.4C) and you live in Canada and need the cooler to be running over the winter, you will be unhappy!
