Customer Reviews
Customer Review: “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 right panel.”
Customer Review: “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 always use headphones anyway.”

Customer Reviews
Customer Review: “This is the 4th one I have had. Same brand. This one needed to be drained 4 times recently. I never had to drain any of the previous ones. Sometimes it fills in one night and sometimes there is no water to be drained so something is not right with it. I had to build a platform and put it on top of it to elevate it slightly.”

Customer Review: “My bedroom is above our garage with a large south facing window. This means it gets super hot no matter the central AC setting.

Customer Review: “I love everything about this but 1. It’s quite, energy efficient and offers 2 speeds and really puts out the cold air. The remote control is easy to use and the temperature controls make sure that you can set it and forget it. It’s really quiet and looks amazing in any room you put in. The only thin…”

Complete Buying Guide for LG Portable Air Conditioners
Essential Factors We Consider
When evaluating LG portable air conditioner reviews, we focus on real-world performance, not just specs. Key factors include cooling capacity (BTUs), room size compatibility, noise level (measured in decibels), ease of installation, smart features like Wi-Fi and app control, energy efficiency, and user-reported reliability. We also test how well units handle humidity, how often they need draining, and whether included accessories (like window kits) are complete and durable.
Budget Planning
LG portable ACs range from around $350 for compact 7,300 BTU models to over $600 for high-end 10,000+ BTU units with smart features. Set your budget based on room size and must-have features: basic cooling starts under $400, while app-enabled models with auto-drain typically cost $500–$650. Don’t forget to factor in potential add-ons like upgraded window kits ($30–$50) if your unit doesn’t include a quality seal.
Final Thoughts
Choosing the right portable AC depends on your space, climate, and tech preferences. LG stands out for reliability and smart integration, but alternatives like Whynter offer superior power for large areas. Always measure your room, check window compatibility, and read recent customer reviews before buying.
Frequently Asked Questions
Q: How do I choose the right BTU size for my room?
A: As a rule of thumb, you need about 20 BTUs per square foot. So a 300 sq ft room needs around 6,000 BTUs, while a 450 sq ft space requires 9,000–10,000 BTUs. Oversizing can lead to short cycling; undersizing means inadequate cooling.
Q: Do LG portable air conditioners require a window?
A: Yes—most LG portable ACs need a window (or wall vent) to exhaust hot air through a hose. The only exception is evaporative coolers, which don’t require venting but work best in dry climates.
Q: Can I control my LG portable AC with my phone?
A: Yes! Models with LG ThinQ technology allow full control via the LG ThinQ app, including scheduling, temperature adjustments, and voice commands through Alexa or Google Assistant.
Q: How often do I need to drain the water tank?
A: It depends on humidity and usage. In high-humidity areas, you may need to drain daily. Many newer LG units feature auto-evaporation or alert systems to reduce manual draining.
Q: Are portable air conditioners energy efficient?
A: They’re less efficient than central AC but comparable to window units. Look for Energy Star ratings and models with programmable timers to minimize electricity use.
Still unsure which LG portable air conditioner is right for you? Our top pick—the LG 10,000 BTU Smart Portable AC—offers the best balance of power, smart features, and reliability for most homes.
