I purchased this unit right before the heatwave started in the south, my main central air unit died. My home is 2200 square feet it was 100 degrees inside, after putting the new LG air conditioner in my home dropped down to 72 degrees. We also used fans to circulate the air. It runs very quiet and cold. I would highly recommend this air conditioner giving it 10 stars ⭐️. You definitely won’t be disappointed.
