New to ductless mini-splits?

A mini-split is a heat pump system with one outdoor compressor unit feeding 1–5 indoor "head" units through small refrigerant lines, no ductwork. Each head is independently controlled — you set the bedroom to 65°F while the living room is 72°F. Modern hyper-heat units (Mitsubishi H2i, Daikin Aurora, Fujitsu XLTH) maintain capacity below 5°F outdoor. Ideal for additions, finished basements, homes without ducts, or selective zoning in older homes. HSPF2 ratings of 9.0+ qualify for ENERGY STAR Most Efficient.

Frequently asked questions

How much does a mini-split cost installed in 2026?

A single-zone mini-split installs for $3,500–$6,000. A 2-zone system runs $7,500–$12,000. A 4-zone whole-home setup typically lands $14,000–$22,000 — economies of shared outdoor unit reduce marginal cost per zone. Cold-climate (Hyper-Heat / Aurora / Halcyon XLTH) adds 15–20%.

Mini-split vs ducted central heat pump?

Mini-splits win when you have no existing ductwork, want per-room temperature control, or have additions/finished basements without HVAC. Ducted wins when you already have good ducts, want centralized filtering, and prefer hidden equipment. Cost is comparable for whole-home — $14,000–$22,000 mini-split vs $10,000–$20,000 ducted, but ducted assumes good existing ducts.

Which brand should I pick?

Mitsubishi Hyper-Heat (H2i) and Daikin Aurora are the cold-climate gold standards — best capacity retention below 5°F, longest service network, highest residuals. Fujitsu Halcyon XLTH is close behind at slightly lower price. LG is solid mid-tier. Avoid no-name imports for permanent installs — warranty service is essentially nonexistent.

Do mini-splits work in cold climates?

Yes — modern hyper-heat models maintain 80%+ rated capacity at 5°F outdoor, 70%+ at -13°F. NEEP’s Cold Climate Heat Pump Specification list (https://neep.org/heating-electrification/ccashp-specification-product-list) certifies which units qualify. Pair with a small backup if your design temp is below -15°F.

Federal tax credit for mini-splits?

The 25C Energy Efficient Home Improvement Credit covered heat pumps at 30% up to $2,000 through 2025-12-31. OBBBA terminated 25C for property placed in service after that date. State + utility heat-pump rebates remain robust: Mass Save up to $10,000, NYSERDA $1,000–$4,000, ComEd $2,250, Energy Trust of Oregon $1,500.
