Frequently Asked Questions by Customers

• What size room is this unit best suited for?
  It is rated for ~ 700 sq ft rooms. If your room is close to this size (or well insulated), it should work well. Smaller rooms will also be cooled efficiently; but for much larger spaces, this might be borderline.
  
  
• Does it require special electrical wiring?
  Yes. You need a 208/230 V supply. This is not compatible with standard 110‑120 V outlets. Also, it draws about 7.6 / 6.9 amps in cooling mode.
   
• Is the filter washable and does the unit have indicators for maintenance?
  Yes. It has a washable filter and a filter alarm / filter‑clean indicator to remind users when to clean.
  
  
• How many fan speeds are there, and what about airflow direction?
  There are 3 fan speeds when cooling, and 3 fan‑only speeds. Air deflection is 4‑way, so you can direct airflow somewhat.
  
  
• Is it noisy?
  Mixed feedback. Spec sheets indicate sound levels ~ 62 dB at high, ~60 dB at mid, ~58 dB low (indoor). Some customers find this acceptable; others feel it's loud or notice fan noise especially at night or in quiet settings.
  
  
• Does it come with a trim kit / installation hardware?
  Yes — the unit is sold with a trim kit. Installation sleeves may be needed (if replacing older units or for mounting). 

Pros

• High Cooling Capacity
  With 14,000 BTU cooling power, it’s suitable for cooling large rooms — up to about 700-750 sq ft in ideal conditions.
• Good Electrical Efficiency & Power Setup
  Designed for 208/230 V operation, draws ~ 7.6 / 6.9 A, consuming ~ 1,500 watts in cooling mode which is standard for this capacity.
• Multiple Modes & Controls
  Offers 3 cooling speeds and 3 fan speeds. Also includes dry mode / dehumidification, fan-only mode, timer (24 hr on/off), remote control, and a filter-alarm indicator.
• Air Distribution / Comfort Features
  Four-way air deflection helps direct airflow more evenly. Washable filter helps with maintenance. Auto-restart after power interruption. Trim kit included for neat mounting.
• Universal Wall Sleeve Compatibility
  Fits many existing wall sleeves (“universal fit”). That can reduce installation cost if you already have a compatible opening.

Cons

• No Heating Function
  This unit is cooling-only (plus fan/dry modes). If you expect to need heating, you'll require a separate unit.
• Noise Levels
  On high settings indoor sound level is ~ 62 dB, which can be fairly loud especially in quieter rooms or at night.
• Energy Efficiency is Moderate
  The CEER/EER is ~ 9.3, which is okay but not top-tier. There are more efficient units out there.
• Wall Sleeve Sold Separately
  The trim kit is included, but the sleeve (which is essential for proper installation) is often not included. That adds to total cost.
• Size, Weight, and Installation Load
  It’s heavy (~ 77 lbs net, ~86 lbs shipping), and dimensions are substantial (~ 24 × 14.4 × 20.1 in). Wall structure needs to accommodate that. Also since it requires 230 V, you need appropriate wiring / power capacity.

Conclusion

The LG LT1430CNR is a strong choice if you need powerful cooling for a large room (≈ 700-750 sq ft), have a compatible through-wall setup or are willing to install one, and have a 230V supply. It’s well-equipped with useful modes (fan / dry / timer), good airflow, and maintenance features; for many users this will provide solid comfort and value.
