Customer Reviews
Customer Review: “We’re in Central Florida and our big air conditioner is wearing out, so we were using two portables in the house to compensate but they weren’t cutting it. I ordered this one and decided to go with the 12,000 BTU and we stuck it in the window where the portable was venting. It’s been on about an hour and already dropped the temp by 10 degrees!”
Customer Review: “This AC is very good, the temperature control is good, and you can use the app to control the temperature from the phone—that was a plus with Wi-Fi connection. The size is perfect for windows and to cool my entire apartment. The downside is that it’s noisy and loud, but good price and works perfect.”

Customer Review: “Just installed this air conditioner. So far, it’s working great. I had to get this model because it required the least window height clearance of any quality conditioner I could find. My older home has storm windows with high base frames, which are a couple of inches higher than the interior window.”
Customer Review: “ADDED PIX OF WHITE/BLUE FILTER PERFORMANCE. As you can clearly see, the filter did keep the white mesh factory filter and the evaporator coils SPOTLESSLY CLEAN. The filter was changed after about 3 months. EDIT: ADDED ENERGY COSTS FROM TAPO UNITS. REVISED ENERGY COST FOR JULY = $66.67 FOR HOME A”
