In Stock 36000 btu

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

Most in-stock mini-splits at MiniSplits4Less leave our warehouse within 1–2 business days. Standard delivery times vary by region but typically arrive within 3–5 business days across the U.S. All orders include tracking updates so you know exactly when your system will arrive — perfect for keeping HVAC installations on schedule during busy cooling seasons.

Not at all — many of our in-stock mini-splits are current-year models with advanced inverter technology, Wi-Fi controls, and up to 23+ SEER2 efficiency ratings. Some discounted closeout units are also available, clearly labeled, and still backed by warranty. Visit our “In Stock” section at MiniSplits4Less.com for the latest ready-to-ship options.

Start by matching your square footage to BTU capacity, then adjust for insulation, ceiling height, and sun exposure. For example, a 12,000 BTU system cools roughly 500–600 sq ft under normal conditions. Our free “Size-My-Room” tool on MiniSplits4Less.com helps you find the right in-stock unit by ZIP code and layout. Each product listing also displays recommended room sizes and zone support.
