How we spot a deal

We record every unit's price at every retailer once a day. A unit earns a place here only when its current, in-stock price is the lowest in our available history from the last 120 days for that seller, and it has genuinely trended down (confirmed over several days of tracking, not a single overnight change) by at least 5% and $20 off an earlier price we recorded, never a manufacturer list price. The moment the price rises or the unit goes out of stock, it drops off this list.

Frequently asked

How do you know an air conditioner is a deal?
We record each unit's price at every retailer once a day. A unit appears here only when its current, in-stock price is the lowest in our available history from the last 120 days for that seller AND it has genuinely trended down (confirmed over several days of our own tracking, not a single overnight change) by a meaningful margin (at least 5% and $20) off an earlier price we recorded. It is never an invented "sale" or a discount off a manufacturer list price.
Is the 'was' price a real price?
Yes. The crossed-out price is a price the unit actually held for several days at that same retailer before this drop, the most recent such level above today's price, shown with the date. We deliberately do not use the single highest price we ever saw (a one-day spike would overstate the discount), and we never compare against a manufacturer's suggested retail price or a made-up original.
How often is this list updated?
Prices and stock are checked every day. A unit drops off this list the moment its price rises again or it goes out of stock, so what you see is current, not a stale banner.
Do you make money from these links?
compare.ac may earn a commission if you buy through a retailer link, at no extra cost to you. It never changes the price you pay and never affects whether a unit appears here: placement is decided purely by the tracked price drop.
