In Stock Single zone ductless mini split air conditioner heat pumps Olivia series

In-stock systems ship immediately—ideal for urgent installs or peak-season replacements. With labor and heatwaves both in high demand, waiting 4–6 weeks on backorders could delay your whole project. At MiniSplits4Less.com, we stock top-performing brands and BTU ranges year-round so you can move fast and stay cool. Bonus: many in-stock units still qualify for 2025 energy rebates and come with full warranties.

Most in-stock mini-splits at MiniSplits4Less leave our warehouse in 1–2 business days. Standard shipping times vary by region, but delivery is typically within 3–5 days for most U.S. addresses. We also offer tracking updates, so you know exactly when your kit will arrive. Fast shipping helps HVAC crews stay on schedule—especially during peak cooling season.

Nope—many of our in-stock mini-splits are current-year models with premium features like inverter tech, Wi-Fi, and 23+ SEER2 ratings.. If you’re looking for value, we do include some closeout units, but they’re clearly marked and still backed by warranty. Check our “In Stock” tab at MiniSplits4Less.com for current options.

Start with square footage—then fine-tune using insulation, ceiling height, and sun exposure. A 12,000 BTU head cools 500–600 sq ft under average conditions. For precise help, our free “Size-My-Room” tool on MiniSplits4Less.com matches you to an in-stock system by ZIP code and layout. We also label our fast-ship kits with supported room sizes and zones, so you know you’re getting the right fit.
