What impressed me most is how quiet this unit operates at 52dB – that’s quieter than a normal conversation. I could sleep comfortably with it running on low mode, which is rare for budget AC units.

The installation process took me about 45 minutes solo, but having a helper would make it easier. At 39.6 pounds, it’s manageable for most adults. The included window kit fits most standard double-hung windows.

Cooling performance is solid for small spaces. It lowered my 12×12 bedroom from 82°F to 70°F in 25 minutes. The two cooling speeds and three fan speeds give you decent control, though it lacks the precision of more expensive models.

Customer photos show the compact design fits well in various window types. Many users appreciate how it doesn’t block too much natural light when installed properly.

When you need serious cooling power for large spaces, the LG LW2422IVSM delivers. This 14,000 BTU monster can cool areas up to 700 square feet – perfect for open-concept living areas, large master bedrooms, or small apartments.

The dual inverter technology is even more impressive at this capacity. It maintains consistent temperatures across large rooms without the hot spots common in less powerful units. During my testing, it kept my 650 sq ft open living area at a uniform 72°F even when outdoor temps hit 95°F.

Energy efficiency is remarkable for a unit this powerful. It’s 35% more efficient than ENERGY STAR requirements, which translates to significant savings on summer electricity bills. One user reported saving $63 per month compared to their old 12,000 BTU unit.

The R-32 refrigerant is a key feature – it’s more environmentally friendly and contributes to the unit’s impressive 10.7 EER rating. This efficiency translates to lower operating costs compared to older units using traditional refrigerants.

This unit is ideal for replacing existing through-the-wall ACs. It fits standard 26-inch wall sleeves, making upgrades straightforward. The included trim kit provides a clean, finished look around the installation.

How to Choose the Best LG Air Conditioner?

What BTU Rating Do You Need?

BTU (British Thermal Unit) rating determines cooling capacity. Use this simple guide: 5,000 BTU for rooms up to 150 sq ft, 6,000 BTU for 150-250 sq ft, 8,000-10,000 BTU for 300-450 sq ft, and 12,000+ BTU for spaces over 500 sq ft. Add 10% more BTUs for kitchens or rooms with high ceilings.

Window vs Portable vs Through-Wall Installation

Window units offer the best efficiency and cooling power but require window installation. Portable units provide flexibility but use more energy. Through-wall units are permanent solutions ideal for replacements or situations where windows aren’t available. Check out our detailed portable vs window AC comparison for more insights.

Understanding LG’s Dual Inverter Technology

Dual inverter compressors vary speed continuously rather than cycling on/off. This results in 25-35% energy savings, ultra-quiet operation, and more consistent temperatures. The technology is especially beneficial for bedrooms and areas where noise is a concern.

Smart Features: Are They Worth It?

LG’s smart features include WiFi control, voice commands, and scheduling. They’re genuinely useful if you want to pre-cool rooms before arriving or adjust temperature remotely. The app works well and adds convenience that quickly becomes habit-forming. Learn more about smart WiFi air conditioners to decide if they’re right for you.

Energy Efficiency and Operating Costs

Look for CEER ratings (Combined Energy Efficiency Ratio). Higher CEER means lower operating costs. Dual inverter models typically have CEER ratings above 12, while standard units range 8-11. A more efficient unit might cost $100-200 more but can save $200-400 annually in electricity.

Installation Considerations

Window units require proper support and sealing. Most LG units include installation kits, but have someone help – they’re heavy. Through-wall units need existing sleeves or professional installation. Portable units need window venting but no permanent installation. Always measure your window or wall space before purchasing.
