Best time to buy an air conditioner is during the off-season — specifically September through February. Most shoppers wait until summer heat hits. By then, prices peak and inventory runs low. Smart buyers plan ahead and shop when demand drops. Retailers like Home Depot, Lowe’s, and Best Buy slash AC prices during fall and winter months. You can save 20% to 40% by timing your purchase correctly. This guide breaks down the exact months, holidays, and strategies to help you land the lowest price on a new cooling system in 2026.

The best time to buy an air conditioner falls between October and February. During these months, retailers aggressively discount units to clear warehouse space. Demand drops to its lowest point. HVAC contractors also lower installation rates because their schedules open up. You can often save 20% to 40% compared to peak summer pricing.
March and April still offer decent savings. New AC models typically arrive at retailers in late spring. That means last year’s models get marked down 15% to 25%. If you don’t need the latest features, these outgoing models deliver excellent value. Walmart and Costco are especially good for clearance window units during this period.
Avoid buying in June, July, or August if possible. These are the worst months for pricing. Retailers know demand is high and rarely offer meaningful discounts. Installation wait times can stretch to two or three weeks. The best time to buy an air conditioner is never during a heat wave.
Holiday Sales and Seasonal Events That Offer the Biggest AC Discounts
Several holiday weekends throughout the year mark the best time to buy an air conditioner at a steep discount. Black Friday and Cyber Monday in late November consistently deliver the deepest cuts. Expect 20% to 45% off at major retailers. Amazon, Best Buy, and Home Depot all run major appliance promotions during this period. In 2025, some brands like TOSOT offered up to 48% off select units on Cyber Monday.
Amazon Prime Day in mid-July is another strong window. It falls during peak summer, but Amazon uses it to compete aggressively. Window units and portable ACs often see 25% to 35% discounts. Memorial Day weekend in late May also brings solid deals. Home Depot and Lowe’s typically run appliance sales with 15% to 30% off. This is the best time to buy an air conditioner if you need it before summer starts.
Labor Day in early September signals the start of the off-season. Retailers begin marking down summer inventory. Discounts of 15% to 25% are common across central, window, and mini-split units. The best time to buy an air conditioner for the following year is often right after Labor Day. Presidents’ Day in February is an underrated sale event too. Many appliance retailers run promotions with 10% to 20% off HVAC equipment.
Pro Tips for Scoring the Lowest Price on an Air Conditioner
Track new model release dates. Manufacturers like Carrier, Trane, and Lennox release new models in late spring. When new units arrive, last year’s models drop in price. This is the best time to buy an air conditioner if you want quality hardware at a discount. The features between model years are often nearly identical. Ask retailers specifically about outgoing models.
Watch for refrigerant regulation changes. New federal regulations now require low-GWP refrigerants like R-32 and R-454B. Units using the older R-410A refrigerant are being phased out. This transition has pushed prices up 20% to 25% on newer compliant models. If you find a remaining R-410A unit at clearance pricing, it can still be a smart purchase. Just confirm your HVAC technician can service it long-term.
Use price tracking tools. Set alerts on CamelCamelCamel for Amazon listings. Use Google Shopping price alerts for units at Best Buy and Walmart. The best time to buy an air conditioner isn’t always predictable. Flash sales and lightning deals can appear without warning. Price tracking ensures you never miss a surprise markdown. Also consider buying floor models or open-box units at Home Depot and Lowe’s for an extra 10% to 15% off.
Bundle installation with the purchase. Many HVAC companies offer package deals during slow months. January through March is the best time to buy an air conditioner and schedule installation together. Contractors may discount labor by 10% to 20% just to keep their crews busy. Get at least three quotes and mention competing offers to negotiate further.
