Frigidaire quietly discontinued its casement AC line — here's what still fits
Frigidaire no longer sells either of its casement air conditioners. The FHSC082WB1 (8,000 BTU) and FHSC102WB1 (10,000 BTU) product pages at frigidaire.com were converted to support-only pages — manuals and parts, no price, no way to buy — sometime between July 4 and July 12, 2026, with no announcement we could find. That leaves just two casement lines in production — Keystone's two units and Perfect Aire's single 10K slider — and prices are already climbing. Owners keep their manuals and parts pages; shoppers should read on before paying the new going rate.
We may earn a commission when you buy through some links on this page, at no extra cost to you — it's how we keep the reviews free. We only recommend what we'd buy ourselves, and we tell you when our top pick isn't one we earn on. See how we earn. How we earn.
If you own a Frigidaire casement unit
Nothing changes this season. Frigidaire's support pages, manuals and parts listings for both models were still up when we checked on July 12, 2026, and discontinuation doesn't void an existing warranty. The practical advice: download the PDF manual now while the page is live, and if a repair ever needs a part, order sooner rather than later — parts availability for discontinued lines shrinks over time.
What still fits a casement or sliding window
Three honest paths remain, and our full fit-first guide covers the measurements for each. The short version:
Keystone KSTSW08B
$464–500 (retailer-dependent) as of 2026-07-12
The unit that inherited the category. Same vertical form factor and 8,000 BTU rating as the discontinued Frigidaire, with a dehumidifier mode — and a street price that jumped from $365–430 to $464–500 in the eight days after Frigidaire's pages went dark. It's still the right buy for rooms up to about 350 sq ft; just shop more than one retailer.
- Type
- Casement/slider window AC
- Cooling Btu
- 8,000 BTU
- Coverage
- Up to 350 sq ft
- Speeds
- 3
- Extras
- Dehumidifier mode, 4-way louvers, remote
Where it earns its price
- The only 8K casement unit still in production
- Dehumidifier mode earns its keep in shoulder seasons
- Widely stocked (Amazon, Walmart, Best Buy)
Where it doesn't
- Prices are climbing with the competition gone — the July 4 to July 12 move was roughly 20% at the midpoint
- Brand support network is thinner than Frigidaire's was
- We could not verify per-speed noise figures from the manufacturer
Skip it if: your room is over 350 sq ft — the 10K below is the honest step up.
Sold out — no active buy link (restock TBC)
Keystone's own page lists it at $463.99 (Amazon) and $479.99 (Home Depot, Walmart) against a $499.99 list, and Best Buy's price API confirmed $479.99 in-stock — all checked 2026-07-12. Prices moved up from the $365–430 spread we saw on 2026-07-04, so shop around.
Keystone KSTSW10B
$529.99 as of 2026-07-12
Keystone's 10,000 BTU casement — at this capacity the alternative is Perfect Aire's 4PASC10000 ($569 at Sylvane, in stock 2026-07-12). $529.99 list at Keystone as of July 12, 2026. Several retailers showed it on backorder when we checked — the discontinuation squeeze is tighter at this capacity.
- Type
- Casement/slider window AC
- Cooling Btu
- 10,000 BTU
- Coverage
- Up to 450 sq ft
- Speeds
- 3
- Extras
- 4-way louvers, remote
Where it earns its price
- The remaining path to 450 sq ft of casement cooling
- Same window fit as the 8K sibling — a bigger room doesn't demand a wider window
- $529.99 list price at Keystone (as of 2026-07-12)
Where it doesn't
- Some retailers showed it on backorder in early July — confirm stock before scheduling an install
- Pricier per BTU than the 8K at street prices
Skip it if: you can't wait out a backorder — the Perfect Aire below is in stock, or the slide-kit path works this week.
No direct buy link we earn on — search “Keystone KSTSW10B” at your usual retailer and confirm stock before you count on it.
No buy link here on purpose: Keystone sells only through retailers and we couldn't verify a direct product page that reliably works — search 'KSTSW10B' at your preferred retailer and check stock before planning an install date.
Perfect Aire 4PASC10000
$569.00 as of 2026-07-12
The 10K unit you could actually buy the week we published this: in stock at Sylvane at $569, server-verified 2026-07-12, while the Keystone 10K showed backorders. Follow Me remote thermostat, dry mode, energy-saver cycle. One real constraint: the fit window is narrow — the opening must be 15.5–16.25 inches wide.
- Type
- Casement/slider window AC
- Cooling Btu
- 10,000 BTU
- Coverage
- Up to 450 sq ft
- Window Fit
- 15.5–16.25 in wide × 21.25–39.5 in tall
- Speeds
- 3
- Extras
- Follow Me remote thermostat, dry mode, energy saver, 24-hr timer
Where it earns its price
- In stock at Sylvane when the rest of the 10K casement field was backordered or discontinued
- Follow Me remote doubles as the thermostat — cools to how the room feels where you sit
- Standard 125V/15A outlet, no special wiring
Where it doesn't
- Opening must be 15.5–16.25 inches wide — stricter than the Keystones; measure first
- $569 is the priciest 10K casement path as of July 12
- We could not verify manufacturer noise figures
Skip it if: your opening is narrower than 15.5 inches — the Keystone pair, or the slide-kit path below.
Sold out — no active buy link (restock TBC)
Amazon buy box live, server-verified 2026-07-22 (also listed at $569.00 at Sylvane on 2026-07-12). Fit is narrower than it looks: the opening must be 15.5–16.25 inches wide — measure before ordering. 125V/15A NEMA 5-15P plug (standard outlet).
Questions people actually ask
Is the Frigidaire casement air conditioner discontinued?
Yes. Both models — the 8,000 BTU FHSC082WB1 and the 10,000 BTU FHSC102WB1 — are no longer sold by Frigidaire. Their pages at frigidaire.com became support-only (manuals and parts, no price or cart) between July 4 and July 12, 2026. We verified both pages directly on July 12, 2026.
What replaced the Frigidaire casement AC?
Nothing from Frigidaire — no successor model is listed. The casement (vertical) air conditioners still in production are Keystone's KSTSW08B (8,000 BTU) and KSTSW10B (10,000 BTU), plus Perfect Aire's 4PASC10000 (10,000 BTU slider/casement, $569 in stock at Sylvane as of July 12, 2026).
Can I still buy a Frigidaire casement air conditioner anywhere?
Only as residual retailer stock, and it sells at whatever the retailer asks. There is no restock coming, so treat any listing as the end of the line: worth it at a clear discount, not at a premium over the in-production Keystone.
Will Frigidaire still support my casement AC with parts and manuals?
As of July 12, 2026 the support pages, manuals and parts listings for both models are still up at frigidaire.com, and discontinuation does not cancel an existing warranty. Download the manual PDF now and order any known-worn part sooner rather than later — parts for discontinued lines get scarcer over time.
Do I have to buy a casement unit at all?
No. A regular single-hose portable AC vented through a slide-kit panel (about $40) fits vertical and horizontal sliders from 11 to 61 inches, keeps you in a competitive market with many models, and leaves the window unmodified — usually the renter's answer. A saddle-style unit is a third option for openings 24 to 48 inches wide.
