5 Zone Single zone ceiling cassette ductless mini split ac heat pump

Start with 20 BTU of cooling for every square foot—the DOE’s 2025 rule-of-thumb for modern insulation. A 2,800 sq ft home therefore needs about 56,000 BTU total. Because a Penta Zone splits that load across five rooms, most owners pair a 48k–60k BTU (4–5-ton) outdoor unit with 9k–12k heads and still pass Manual J. Correct sizing avoids short-cycling and keeps SEER2 efficiency on-spec. Try the free “Size-My-Room” widget on MiniSplits4Less to dial in each head before you order.

National install surveys for 2025 show five-zone ductless projects landing between $9,500 and $15,500 turnkey. Equipment makes up roughly two-thirds of that: today’s 48k BTU, 21 SEER2 Penta Zone kits run $5,800–$7,800, while labor, electrical and permits add $3,000–$7,000 depending on line-set lengths and attic work. Our in-stock Cooper & Hunter 48k BTU Penta Zone packages at MiniSplits4Less.com already include the 25 ft LineGuard kits most contractors upsell, so you can stay near the low end of the range.

Yes. As of January 1, 2025, any five-zone mini-split that meets the ENERGY STAR Most Efficient—or the new Cold-Climate—label qualifies for the 30 % Federal Heat-Pump Tax Credit, capped at $2,000 per system. Many utilities sweeten the pot with $300–$1,200 per outdoor unit; punch your ZIP into the ENERGY STAR Rebate Finder to see what stacks locally. We flag qualifying R-32 and R-454B Penta Zone kits right on each product page at MiniSplits4Less, so you can capture both credits in one checkout.

A single 5-zone condenser is usually simpler and cheaper than running five separate single-zone units. You drill one set of wall penetrations, pull one 240-V circuit, and get diversity savings—light-load rooms let the inverter ramp down instead of cycling multiple compressors. The trade-off is risk: if the outdoor compressor ever fails, all five heads go offline until service arrives. That’s why we recommend brands with 10-year parts warranties and easy-swap control boards—look for our on Penta-Zone bundles at MiniSplits4Less to hedge downtime.
