Summer temperatures are climbing and if your cooling setup isn’t ready, now is the time to fix that before it gets uncomfortable. Whether you need a portable unit you can move from room to room, a window AC to cool a specific space or a ductless mini split for a more permanent solution, the Slickdeals community has been tracking down some solid deals across all three types. Here’s a look at what’s worth buying right now.

Refurb Midea DUO Dual-Hose 12,000 BTU Portable Air Conditioner: $229.99

The Midea DUO Dual-Hose 12,000 BTU Portable Air Conditioner (Walmart Restored) is currently $229.99 at Walmart with free shipping. As a refurbished unit, it only comes with a 90-day return window, but it also has a one year warranty. On the upside, it’s a capable machine: it cools, ventilates and dehumidifies, features inverter technology that delivers up to 40% energy savings compared to the U.S. federal standard and comes with Matter certification for app and voice control. It carries a 3.5 out of 5 star rating. We saw the same deal last year (technically it was $5 less) and it got a +81 score and 190+ comments. One community member who compared the refurb option with buying new noted that the value comes down to what warranty you need, adding the two-year coverage on new units is worth paying a bit more for if peace of mind matters to you. The deal has a +5 score.

Midea 12,000 BTU Smart Inverter Window Air Conditioner with MShield: $329.99

Costco members can pick up the Midea 12,000 BTU Smart Inverter Window Air Conditioner with MShield (MAW12AV1QWT-C) for $329.99, down from $430 — a $100 manufacturer’s savings valid through June 7, 2026. Non-members can still purchase but will pay a 5% surcharge. The unit covers spaces up to 550 sq. ft., is Energy Star certified, delivers 35% energy savings compared to DOE minimum requirements and includes MShield Air Ionizer technology that reduces odors, smoke and gases in the air. It also supports app and voice control via Matter certification. Customers have rated it 4.5 out of 5 stars from over 290 reviews. One verified owner said he’d “buy this again if mine failed” and another who installed it recently called setup simple, adding it “blows ice cold.” The deal has a +77 score with over 23,000 views.

Costway Airtural Series 18,000 BTU Ductless Mini Split AC + Heater: $609

For larger spaces or a more permanent installation, the Costway Airtural Series 18,000 BTU Ductless Mini Split Air Conditioner and Heater is $609 at Costway after applying coupon code XQFP10518 in cart, down from $799 — saving $190. Shipping is free. The unit handles both heating and cooling, covers up to 1,250 sq. ft., offers 7 modes and 4 wind speeds, carries a 21 SEER2 efficiency rating and is certified by Energy Star, ETL and AHRI. A comprehensive installation kit is included, though a community member noted the install does involve electrical work and potentially refrigerant adjustment, so budget for that if you’re DIYing it. The offer is valid through May 30, 2026 while supplies last. The deal has a +43 score with over 20,000 views.

Whynter ARC-131GD 13,000 BTU Dual-Hose Portable Air Conditioner: $200.99

The Whynter ARC-131GD 13,000 BTU Dual-Hose Portable Air Conditioner is $200.99 at Walmart, and the community noted it’s available at the same price at Best Buy and Home Depot as well. The unit includes dehumidifier and fan modes alongside cooling and is rated for spaces up to 420 sq. ft. The dual-hose design makes it more efficient than single-hose portable units, since it draws air for the condenser from outside rather than from the room being cooled. Shipping is free. The deal has a +13 score.

Midea 12,000 BTU DUO Smart Inverter Portable Air Conditioner: $409.99

Costco members can also get the new Midea 12,000 BTU DUO Smart Inverter Portable Air Conditioner for $409.99, down from $520 — a $110 manufacturer’s savings valid from May 8 through June 7, 2026, with a limit of 5 per member. Shipping is free. Like the window version above, it covers spaces up to 550 sq. ft., is Energy Star certified, features inverter technology for up to 40% energy savings and includes MShield Air Ionizer technology and app and voice control via Matter. The dual-hose design improves efficiency over single-hose portables. The deal has a +11 score.
