The LG LW8023HR 7,600 BTU Window Air Conditioner with Heat is a 115V cooling and supplemental heating unit for bedrooms and offices up to 330 square feet. It is one of the few heat and cool conventional window air conditioners at this size that runs on a standard household outlet.
It adds a remote, a 24-hour timer, 4-way air deflection, Auto Restart and a slide in-out chassis. The main considerations are its weight and only 2 fan speeds. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This LG is a practical year-round unit for a medium room. Its strongest points are cooling plus supplemental heat on 115V power, a remote, 2 cooling, heating and fan speeds, a 24-hour timer, 4-way air deflection, Auto Restart and a slide in-out chassis. LG lists sound as low as 52 dB in low mode, and the specification sheet lists 50 dB.
The trade-offs are weight and some listing inconsistencies. At 69 pounds, it is heavy for its size, it has only 2 fan speeds, and the listing does not state the heating capacity. The title gives 7,600 BTU while the specification sheet lists 7500. It holds 4.1 stars from 22 ratings. If you want cooling and mild-weather heat for a bedroom or office without a special outlet, it is worth considering.

Cooling Capacity and Room Size
LG rates the unit for medium rooms up to 330 square feet, about 16′ x 20′, and names bedrooms and offices. The product title lists 7,600 BTU, while the specification sheet shows 7500 BTU; either way, it sits just below the common 8,000 BTU size.
The supplemental heat is designed for cooler days, taking the chill off a bedroom or office in spring and fall. It is not a replacement for a primary heat source in winter.
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Adjust for your room: reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
At its listed capacity, it falls between the chart’s 7,000 BTU row (250 to 300 square feet) and its 8,000 BTU row (300 to 350 square feet), so LG’s 330 square foot claim is a reasonable upper limit.
Installation and Fit
The listed window opening is 22 to 36 inches wide with a minimum height of 14 inches. An installation kit, remote and mesh filter are included. The slide in-out chassis lets the working part of the unit slide out of its outer case; check the manual for how LG recommends using it during installation.
The cabinet measures 18.4 inches deep, 20.9 inches wide and 13.9 inches tall, and weighs 69 pounds. That is heavy for this capacity, so plan on two people. Follow the manual and plug it into a standard 115V outlet; at 1260 watts, check for a dedicated circuit recommendation.
Noise, Energy Use and Efficiency
LG lists sound levels as low as 52 dB in low mode, and the specification sheet gives 50 dB. Either way, it is quiet enough for a bedroom on the lower fan speed.
The listing gives an efficiency figure of 11.3, labeled as SEER, and a power draw of 1260 watts, which likely reflects the heater. There is no inverter. The 24-hour timer helps you limit running time.
Controls and Smart Features
The included remote handles cooling, heating and fan settings. You get 2 speeds for each mode, a 24-hour timer and 4-way air deflection to direct air where you need it.
Auto Restart turns the unit back on after a power failure. There is no Wi-Fi or app control.
A practical routine in spring and fall is to use the timer to start heat before you get up on cool mornings, then switch to cooling on warm afternoons.
Maintenance and Drainage
The washable mesh filter is easy to remove and rinse. Because this unit can run for both heating and cooling, check the filter regularly through the year.
The listing does not describe condensate drainage. Check the manual for how water is handled in both modes and for seasonal storage steps.
