I purchased this unit to replace an old AC unit that was tripping the breaker when switching between fan and turning on the compressor. First impressions, this AC unit is very quiet, has many features and is easy to use and set up. I liked it so much I bought one for each additional bedroom and one for the downstairs living room. The App is very useful to monitor temperatures and status of each unit in the different rooms in the house, even when you are away from the home. Having the app makes it very convent to power off a unit if you forget before leaving the house.
