“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”

“We’re in Central Florida in 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 “

“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”
Complete Buying Guide for Lg Quiet Air Conditioner
Essential Factors We Consider
When choosing an LG quiet air conditioner, we focus on noise level (measured in decibels), cooling capacity (BTUs matched to room size), energy efficiency, ease of use (remote, controls, installation), and smart features like Wi-Fi or app integration. Quiet operation is non-negotiable—most LG models operate at or below 52dB, quieter than a library whisper.
Budget Planning
LG’s quiet ACs range from under $200 for basic 6,000 BTU window units to over $500 for high-end smart or portable models. Set your budget based on room size and desired features: a small bedroom needs less power (and costs less), while large or smart-enabled units justify higher investment. Always factor in long-term energy savings—LG’s efficient designs can lower monthly bills.
Final Thoughts
Whether you prioritize silence, smart tech, portability, or pure cooling power, LG offers a quiet air conditioner that fits your lifestyle. Our top picks balance performance, noise control, and value—so you can enjoy cool, peaceful comfort all summer long.
Frequently Asked Questions
Q: How quiet are LG air conditioners really?
A: Most LG quiet air conditioners operate at 52dB or lower in low mode—quieter than a normal conversation (60dB) and comparable to a whisper. This makes them ideal for bedrooms, nurseries, or offices.
Q: Can I control an LG quiet AC with my smartphone?
A: Yes! Select models feature LG ThinQ Wi-Fi technology, allowing you to adjust temperature, set schedules, and monitor energy use via the LG app—or through voice commands with Alexa or Google Assistant.
Q: What size LG air conditioner do I need for my room?
A: Match BTUs to room size: 6,000 BTU for up to 250 sq ft, 10,000 BTU for 300–450 sq ft, and 14,000 BTU for 500–700 sq ft. Oversizing wastes energy; undersizing won’t cool effectively.
Q: Are LG window ACs hard to install?
A: Not at all! Most LG window units include simple mounting hardware and fit standard double-hung or sliding windows. Allow 1–2 hours for DIY installation—or hire a pro for wall-mounted models.
Q: Do LG air conditioners save energy?
A: Yes. LG designs its ACs with energy-efficient compressors and smart modes (like Auto Cool) that reduce power consumption. Look for ENERGY STAR® certification for maximum savings.
