Keeps room super chill during the 100+ heat in California. Has a timer and scheduler to have it turn on/off at preferred times. Have seen our overall electric bill go down now that we don't have to run the house a/c just to cool a few rooms. The installation was expensive, but that's not Della's fault. We paid an electrician $800 to install this, which also included adding a new breaker just for this split a/c. Review: Installing these, instead of havc systems from now on. - Installed two for these, 1st time using mini splits, seem to be quality, time will tell, advice make sure your line set connections are tight, have leak detector solution, they put extra Freon in system, so you have time to stop leak if you have one. ## Features - [AMPLE COVERAGE] This unit provides cooling and heating for up to 650 square feet and is able to work in environments as low as 19 degrees Fahrenheit.
