Quick Answer: At 14,000 BTU — the top of the window-AC size ladder, covering up to 700 sq ft — the best window air conditioner in 2026 is the Midea MAW14V1YWT-S (~$400), the quietest and cheapest true inverter option at this capacity with a published noise floor as low as 41 dBA. The LG LW1522IVSM (~$529–599) is the pick if you want the biggest published coverage (up to 800 sq ft) and Dual Inverter efficiency, and the Frigidaire Gallery 14,000 BTU Smart Inverter (~$549) is the pick if you already trust the Frigidaire lineup from a smaller size. The GE Profile PWDV14WWF (~$570–579) rounds out the field but is confirmed discontinued by GE — buy it only at a genuine clearance price. All four cover roughly 700 sq ft per the US Department of Energy’s ~20 BTU/sq ft sizing rule.
Every brand roundup on this site tops out with a 14,000 BTU large-room pick, but until now nothing put those top-tier units side by side. This guide lines up the four brands’ 14,000 BTU models directly against each other, the same way our 8,000 BTU, 10,000 BTU and 12,000 BTU shootouts do for their size classes — completing the full 6K/8K/10K/12K/14K chain.
14,000 BTU window ACs, by the numbers
| Metric | Figure | Source |
|---|---|---|
| Estimated coverage at 14,000 BTU | ~700 sq ft | US DOE, ~20 BTU/sq ft baseline (confirmed by Midea, LG, Frigidaire and GE listings) |
| Midea MAW14V1YWT-S noise floor | as low as 41 dBA | Midea spec sheet, quietest of the four compared here |
| LG LW1522IVSM published coverage | up to 800 sq ft | LG.com product page (higher than the DOE-baseline 700 sq ft estimate) |
| GE Profile PWDV14WWF status | discontinued, no longer manufactured | GE Appliances official product page |
A 14,000 BTU window AC covers about 700 sq ft under the US Department of Energy’s rough sizing rule of roughly 20 BTU per square foot — the largest single-window box most brands sell before you’d need multiple units or a mini split instead. LG rates its LW1522IVSM slightly higher, up to 800 sq ft, but treat manufacturer coverage claims as an upper bound and the DOE math as the safer planning number, especially for a sunny room or a top floor.
Our top picks at a glance
| Unit | Best for | Noise | Coverage | Price |
|---|---|---|---|---|
| Midea MAW14V1YWT-S | Best overall / quietest | as low as 41 dBA | 700 sq ft | ~$400 |
| LG LW1522IVSM | Best coverage / efficiency | ~44 dB | up to 800 sq ft | ~$529–599 |
| Frigidaire Gallery 14K Smart Inverter | Best if you're already in the Frigidaire lineup | Inverter-quiet | 700 sq ft | ~$549 |
| GE Profile (PWDV14WWF) | Clearance only — discontinued | ~44 dB | 700 sq ft | ~$570–579 (while stock lasts) |
1. Midea MAW14V1YWT-S — Best Overall
Midea MAW14V1YWT-S (14,000 BTU)
- Quietest unit in this comparison — Midea's spec sheet lists a noise floor as low as 41 dBA, the lowest published figure at this capacity.
- Confirmed $399.99 at Target, typically the cheapest true inverter-tier option of the four brands here.
- Smart Inverter technology rated for up to 28% energy savings versus the DOE CEER minimum, per Midea's own figures.

At the top of the window-AC size ladder, the Midea MAW14V1YWT-S keeps the same advantage that makes Midea’s smaller units the pick throughout this site: real inverter hardware at a price that undercuts the competition. Confirmed at $399.99 at Target — roughly $130–180 less than the LG or GE at this capacity — and with a published noise floor as low as 41 dBA, it’s both the cheapest and the quietest of the four brands compared here. This is a standard slab-style window unit rather than Midea’s U-shaped design (the U-series tops out at 12,000 BTU), so it installs like a conventional window AC with no wide-sash requirement. Full lineup, including where the 14K sits against Midea’s U-series, in our Midea air conditioner guide.
2. LG LW1522IVSM — Best Coverage and Efficiency
LG LW1522IVSM Dual Inverter (14,000 BTU)
- LG publishes the highest coverage claim of the four units here — up to 800 sq ft, versus the DOE-baseline 700 sq ft estimate.
- Dual Inverter compressor rated for up to 35% energy savings, per LG's own figures.
- Priced from about $529 (Amazon) to $578–599 at Abt — the widest single-unit price range in this comparison, worth checking multiple retailers.
If your room genuinely pushes past 700 sq ft — an open-plan living/dining combo, a finished basement, or a large primary bedroom — the LG LW1522IVSM is the one brand here that rates its 14,000 BTU model for more, up to 800 sq ft. That’s LG’s own claim rather than the conservative DOE math the rest of this guide uses, so treat it as an upper bound and size down if your room runs hot, sunny, or top-floor. The Dual Inverter compressor holds the same steady, low-cycling profile LG uses across its smaller IVSM models, and ENERGY STAR certification puts real efficiency behind the coverage claim. Our LG air conditioner guide covers the rest of LG’s IVSM lineup and the naming pattern that tells you which models are the good inverter units.
3. Frigidaire Gallery 14,000 BTU Smart Inverter — Best If You’re Already In the Lineup
Frigidaire Gallery 14K Smart Inverter
- Same Gallery Smart Inverter tier as Frigidaire's 8K and 12K window units — consistent app, remote and Wi-Fi experience if you already own one.
- Rated for up to 700 sq ft, matching the DOE-baseline estimate exactly.
- Sits between the Midea (cheaper) and LG (bigger claimed coverage) on price — the middle-of-the-road choice at this capacity.
The Frigidaire Gallery 14K Smart Inverter is the pick for anyone who already owns a Gallery-tier Frigidaire and wants the same app and remote experience scaled up to the biggest room in the house. At around $549 it lands between the cheaper Midea and the LG’s premium pricing, without a standout spec advantage over either — the case for it is consistency with the rest of a Frigidaire-equipped home rather than a best-in-class number on paper. Our Frigidaire air conditioner guide covers the rest of the Gallery lineup, including the 8K and 12K models that share this one’s tier name.
4. GE Profile (PWDV14WWF) — Clearance Only, Discontinued
GE Profile Inverter Window AC (PWDV14WWF)
- Confirmed discontinued — GE's own product page states this model is no longer being manufactured.
- ENERGY STAR certified, rated up to 40% more efficient than the DOE minimum, 44 dB, 700 sq ft — competitive specs while it was in production.
- Only worth buying at genuine clearance pricing; expect thinning parts and warranty support over time on a discontinued model.
We’re including the GE Profile PWDV14WWF here for completeness and honesty rather than a strong recommendation: GE’s own site confirms this model is no longer being manufactured, the same fate that already befell GE’s PPHH12WWF portable. The specs were genuinely competitive while it was current — 44 dB, ENERGY STAR, up to 40% more efficient than the DOE minimum — so remaining retailer stock at a real discount can still be a fair buy. Just don’t pay full price for a model GE has already moved past, and don’t expect long-term parts support the way you’d get from the three current-production units above. Our GE air conditioner guide covers GE’s current AWCS/AWGP/PPHV/ClearView lineup, none of which reach 14,000 BTU in a window form factor.
How to choose among 14,000 BTU window ACs
- Confirm you actually need this much capacity. 700 sq ft is more than most bedrooms and even most living rooms — check our BTU sizing guide before sizing up this far, and consider our 12,000 BTU shootout if your room is closer to 550 sq ft.
- Budget-first buyers should start with the Midea. It’s both the cheapest and the quietest of the four units compared here.
- If your room is genuinely oversized (700+ sq ft), the LG’s 800 sq ft claim is the outlier worth checking, but confirm with the DOE math first — manufacturer coverage claims run optimistic.
- Skip the GE unless it’s on real clearance. A discontinued model at full price isn’t a good trade against three current-production alternatives.
- All four need a standard double-hung or slider window wide and strong enough to support a 14,000 BTU unit’s weight — check our installation guide and bracket roundup before buying if your sill or frame looks marginal.
The bottom line
14,000 BTU is the top of the window-AC ladder, and lining up Midea, LG, Frigidaire and GE at this exact capacity shows a clearer price-and-noise gap than at the smaller sizes: the Midea MAW14V1YWT-S wins decisively on both price and noise for most buyers, the LG LW1522IVSM is the one to reach for if your room genuinely exceeds 700 sq ft, the Frigidaire Gallery 14K is the safe middle choice for anyone already in that ecosystem, and the GE Profile PWDV14WWF is worth a look only as clearance stock. Need a smaller room? Our 12,000 BTU comparison covers the step down, completing the site’s full 6K–14K shootout chain.
