“Very happy with this purchase. Placed it in the apartment above our garage in the existing opening after removing the old unit. It worked for fit and the cord is more than long enough to reach the plug. The fellows who did the install did a really nice job. Keeps the room very cool and comfortable a”
“I had the same experience as Matt Punk. Sadly, I bought the unit over Memorial Day and didn’t use it for weeks because it wasn’t warm enough so I didn’t notice the design flaw until it got into the 90’s with high humidity. Now my return window has expired. It overheats and shuts down with the err”

“I bought this in June of 2023 and it’s held up so far. It has worked great against a couple seasons of those 100+ degrees Fahrenheit summer temperatures. My only complaint is that my unit sometimes rattles on the low fan setting. I don’t why but it seems to stop when I press hard against the front ri”
“I have this in a 12ft x 12ft office. I really like the cooling ability and the easy set up! I decided not to permanently stick the foam on so I can move the unit around if needed. One thing to keep in mind with this unit is it’s kind of loud. I doubt it’s louder than any other portable AC but I alwa”

Frequently Asked Questions
Q: How do I choose the right BTU size for my room?
A: As a general rule, you need about 20 BTUs per square foot. A 150 sq.ft. room needs around 3,000 BTUs, while a 450 sq.ft. space requires about 9,000–10,000 BTUs. Always check the manufacturer’s recommendations for best results.
Q: Are LG portable air conditioners noisy?
A: Most LG portable ACs operate between 50–60dB, which is comparable to a quiet conversation. Lower fan settings are quieter, but noise can increase on high cooling modes—especially in very hot weather.
Q: Can I control LG air conditioners with my phone?
A: Yes! Select LG models feature LG ThinQ technology, allowing you to control cooling, set schedules, and monitor energy use via the LG ThinQ app—compatible with iOS and Android.
Q: Do I need professional installation for LG window or wall units?
A: Window units can usually be installed by homeowners with basic tools. Through-the-wall models often require professional installation to ensure proper sealing and electrical safety.
Q: How often should I clean the filter?
A: For optimal performance, clean the air filter every 2–4 weeks during heavy use. A clogged filter reduces efficiency and can cause the unit to overheat.
