Main trade-off
LG 6,000 BTU Window Air Conditioner
A small room may not need 6,000 BTU.
Head-to-head
Choose the LW6017R when a narrow or low-opening window, remote control or a 6,000 BTU room requirement matters. Choose the FFRA051WAE for a suitably sized 5,000 BTU room when simple manual controls suit you. Its smaller cabinet still requires a wider window opening with the supplied installation kit.
Before you choose
With a 22-inch clear opening, the LG is inside its documented range while the Frigidaire falls short of its 23-inch minimum. Do not choose the Frigidaire simply because its cabinet is physically smaller.
What this is based on
22 lies within 21 to 35, but is below 23. This assumes the supplied kit and an otherwise compliant hung window.
Main trade-off

Main trade-off
The supplied kit needs at least 23 inches of width.


Choose between the LW6017R and FFRA051WAE using your clear window opening, room cooling load and whether you need a remote and shutoff timer.

Winner by situation
LG starts at 21 inches, while Frigidaire requires 23 with its supplied kit.
The federal baseline is 6,000 BTU before room-specific adjustments.
The LG includes a remote, while Frigidaire uses manual controls.
Frigidaire suits a verified 5,000 BTU load and direct manual operation.
What matters in practice
With a 22-inch clear opening, the LG is inside its documented range while the Frigidaire falls short of its 23-inch minimum. Do not choose the Frigidaire simply because its cabinet is physically smaller.
22 lies within 21 to 35, but is below 23. This assumes the supplied kit and an otherwise compliant hung window.
ENERGY STAR’s ordinary-room chart places 200 square feet in the 6,000 BTU band. That makes the LG the starting choice for this example, subject to sun and occupancy adjustments. A small 120-square-foot room instead starts in the 5,000 BTU band.
The examples use published federal sizing bands, not a room test. Frigidaire’s linked sheet has an inconsistent coverage field, so capacity and an independent sizing method govern this comparison.
The LG remote handles an immediate change without getting up, and its timer handles a later shutoff. The Frigidaire requires direct operation for these jobs. If you want simple knobs and never schedule cooling, these extra LG controls may add little to your routine.
This consequence follows from remote and timer availability. Neither control feature establishes faster cooling or lower measured sound.
Try your real numbers
The result checks hard limits only. Preferences stay out of the calculation.
6,000 BTU at 115V with a 21 to 35-inch width range and 12-inch minimum opening height. Your calculated target is 8,000 BTU.
5,000 BTU at 115V with a 23 to 36-inch width range and 13-inch minimum opening height. Your calculated target is 8,000 BTU.
Cooling follows the current room-size method with adjustments for sun, extra people and kitchen heat. The opening check uses the stored manufacturer limits.

Meaningful differences
| What changes | LG 6,000 BTU Window Air Conditioner | Frigidaire 5,000 BTU Window-Mounted Room Air Conditioner | Why it matters |
|---|---|---|---|
| Cooling output | 6,000 BTU | 5,000 BTU | Select the room load first, including sunlight and occupancy. |
| Window width with supplied kit | 21 to 35 in | 23 to 36 in | The narrower cabinet does not have the narrower installation requirement. |
| Minimum clear opening height | 12 in | 13 in | Measure the sash opening, not the glass pane. |
| Everyday controls | Electronic controls and remote | Manual controls, no remote | Remote operation can remove a repeated walk to the window. |
| Delayed operation | 24-hour on/off timer | No 24-hour on/off timer | The LG supports a planned shutoff without reaching its controls. |
What you give up
Recommendation switch
Choose LG 6,000 BTU Window Air Conditioner. The LG installation range begins at 21 inches.
Choose Frigidaire 5,000 BTU Window-Mounted Room Air Conditioner. Frigidaire pairs that output with direct manual operation.
What matters in practice
Measure the occupied room rather than adding closed adjoining rooms. The 200-square-foot example points toward 6,000 BTU before adjustments, while a genuinely small room can suit the Frigidaire. Strong afternoon sun, a kitchen or extra occupants can change the required capacity.
The LG can enter an opening that is both narrower and lower than the Frigidaire’s stated kit minimum. Check width and height together after accounting for the sash, storm-window obstruction and support instructions. A cabinet dimension alone does not establish a safe fit.
Consider the path from your bed or desk to the controls. LG’s remote and timer help when that path is awkward or when you want cooling to end later. Frigidaire’s manual controls suit someone who adjusts the unit in person and prefers that straightforward routine.
