LG 8,000 BTU Window AC Review: A Proven Box Unit for Bigger Rooms

Buy the LG 8,000 BTU Window Air Conditioner with Remote (LW8024RD) for a room of 300 to 340 square feet when you want a plain box unit with a long track record and you don't want to pay for an inverter. LG says it is the same unit as the LW8016ER, an 8,000 BTU model that sold for years, and one owner of that model reports more than 25,000 hours. It is heavy at 58 pounds, it cycles fully on and off, and on Amazon only a third-party seller had it when we checked.

LG's EnergyGuide label puts it at CEER 11.4 and $70 a year at the label's assumptions. An 8,000 BTU class inverter at CEER 15, like the Midea U or LG's own Dual Inverter 8,500, would do the same cooling for about $53 (70 × 11.4 ÷ 15). That $17 a year is real but small; the bigger reasons to buy an inverter are quiet and steadier temperature.

The rules changed under it. DOE's minimum for an 8,000 to 13,900 BTU louvered unit jumped from 10.9 to 16.0 for units manufactured from May 26, 2026. At 11.4, this model can't be built to the new rule, so stock on sale now predates the cutoff. A unit at the new floor uses about 29% less power for the same cooling (11.4 ÷ 16.0 = 0.71), and LG has already certified an 8,000 BTU room air conditioner at CEER 17.6 in DOE's database. Until those reach the shelf at this price, the LW8024RD is a sound buy for the right room.

What we like

• A proven chassis: LG's support team told a buyer the LW8024RD and LW8016ER are the same unit: same 22 to 36 inch window range, same dimensions, same 58 pounds, same features and electrical ratings. The LW8016ER owner record is long and mostly kind.
• Efficient for a non-inverter 8,000: CEER 11.4 on LG's label, against 10.9 for Frigidaire's FHWC083TC1 at the same size.
• Sensible controls: electronic thermostat with a remote, three cooling and three fan speeds, Energy Saver, a 24-hour timer, 4-way air deflection and auto restart after a power cut.
• Short-window friendly: it needs a 13 inch opening, an inch less than Frigidaire's 8,000 BTU unit.

What we'd change

• Weight: 58 pounds net, about 20 pounds more than a 6,000 BTU box unit. Plan on two people.
• Efficiency: CEER 11.4 and no ENERGY STAR. The new DOE floor for this size is 16.0.
• Noise: LG lists 58 dBA on high and 52 on low, and doesn't publish a sleep figure.
• Where to buy: Amazon had only a third-party seller, and LG's own store showed it out of stock for the ZIP code we tried.
• A conflicting spec: LG's product page lists CEER 12 while its EnergyGuide label says 11.4. We go with the label.

Size it to the room and the sun

ENERGY STAR's chart puts 300 to 350 square feet at 8,000 BTU, assuming an 8 foot ceiling, and LG rates this unit for 340. Add 10% for a very sunny room and that same 340 square feet wants about 8,800 BTU (8,000 × 1.10), which is the 9,000 BTU row. So this is the right unit for a living room, a large bedroom or a small studio with ordinary sun. In a west-facing top-floor room near 340 square feet, size up.

The LW8016ER record has a clear warning about that. One owner moved from LG's older LW8011ER to the LW8016ER in a second-floor office with three sunny windows and a PC running all day, and the new unit never got the room cold even at its lowest setting. LG lists 220 CFM for this chassis. If your room has those loads, a 10,000 BTU unit is the safer buy.

Here is where it sits against the 8,000 BTU units you're likely to compare. Figures are each maker's; CEER from the EnergyGuide label or ENERGY STAR.

Don't confuse the LW8024RD with the LW8024R. LG sells both at 8,000 BTU with the same window range and label CEER, but the LW8024R is a lighter 44 pound cabinet that draws more power (730 W against 660 W) and has no Energy Saver mode on LG's spec table. Our review and the owner history here are for the RD.

The specs that matter

From LG's product page, EnergyGuide label and 2025 owner's manual.

Living with Energy Saver

Know this before your first night: the unit switches Energy Saver back on every time you turn it on, except in Fan mode or after a power outage. In Energy Saver, the compressor and fan both stop when the room hits the set point, and the fan wakes about every three minutes to sample the air. That saves power and makes the fan noise come and go. If you'd rather have steady air, press Mode until you're in plain Cool.

The thermostat is a thermistor at the unit, so the far side of the room can be warmer than the number on the display. For humid rooms, a low fan speed pulls more water than high. LG lists 2.2 pints an hour of moisture removal, which helps on sticky days but doesn't replace a dehumidifier in a damp basement.

Installing a 58 pound box

Use two people. LG publishes 58 pounds net for the LW8024RD, and most of the cabinet hangs outside the sash. The manual wants the bottom of the unit 30 to 60 inches above the floor and the back about 1/4 inch lower than the front, so condensate runs outside. Check that with a level before you seal the gaps.

• Window: standard single- or double-hung, 22 to 36 inches wide, with 13 inches clear from the bottom of the upper sash to the inside sill. LG says sleeves and wall openings are not recommended.
• Storm windows: add a 1 x 2 wood strip to the inner sill so its top sits at least 3/4 inch above the storm frame, or the unit can't tilt out to drain.
• Power: a grounded 15 A, 120 V receptacle on a 15 A time-delay fuse or breaker. LG's manual says to use a dedicated circuit, and no extension cords, surge protectors or multi-outlet adapters.
• Cord reach: measure from the window to the outlet before you buy. If the cord doesn't reach, the fix is an outlet installed by an electrician, not an extension cord.
• The slinger: the fan ring picks condensate out of the base pan and throws it on the condenser. The splashing is by design; LG calls it more efficient.

Reliability, from the LW8016ER record

This is where the LW8024RD earns its score. Because LG treats it as the same unit as the LW8016ER, years of owner history apply. The good news is endurance: one Florida owner has more than 25,000 hours on an LW8016ER, after a previous LG 8,000 lasted 35,000. The wear they report is mechanical and fixable, like rubber compressor mounts that dried out and needed shims.

The common failure is the indoor fan. A whine between cooling cycles that grows into a grinding rumble points to a worn fan bearing, and one owner has had it on two LW8016ERs. A piece of foam caught in the fan is the other noise report. LG's manual says only an authorized service center or dealer should clean the interior, so a bearing past the warranty usually means a paid repair or a new unit.

The warranty is a year of parts and labor, with in-home service where LG offers it. It covers only the original retail purchaser, needs proof of purchase with the model and date, excludes open-box and refurbished units, and requires shipping damage to be reported within a week of delivery. It also has a binding arbitration clause with an opt-out. If you buy from a third-party seller, make sure you get a receipt that names the model.

How it compares

• Frigidaire FHWC083TC1: the same price when we checked and sold by Amazon, but CEER 10.9 and a 14 inch opening. Frigidaire lists 320 CFM on high and up to 59 dBA. Pick it if you want Amazon's return policy; pick the LG for the efficiency and the record.
• Frigidaire 6,000 (FHWC063TC1): the smaller, cheaper step for a room under 250 square feet: CEER 11.0, 5.1 A, and about 38 pounds on Amazon's data.
• Midea U 8,000: the quieter bedroom choice at CEER 15 with the compressor outside a closed sash, if your window gives it 13.75 inches. Check the V1UWT suffix; earlier U models were recalled.
• Midea 8,000 with Heat: if the room also wants spring and fall heat: an inverter heat pump at CEER 14.5 that heats down to 41°F outside.

Our verdict

Buy it for a 300 to 340 square foot room with ordinary sun if you want a box unit with a long, mostly good record and you can lift 58 pounds with a helper. Buy from a seller that gives you a model-specific receipt, check the 1/4 inch tilt, put it on its own circuit, and listen for fan-bearing whine while the warranty is young. If the room is a bedroom and you sleep lightly, or it bakes in the afternoon, spend more on an inverter or a bigger unit instead.
