Single-zone mini-split: the short answer

As configured, budget roughly $3,000 – $5,000 for a single-zone mini-split, rising toward $5,500 – $12,500 once new ductwork and electrical work are included. Because there is no ductwork and only one indoor head, a single-zone mini-split is the simplest and usually the least expensive heat pump install. Cost still moves with the head's capacity, the line-set length, and any electrical work. The biggest swing is still your own site, so itemize your estimate above.

These figures are indicative ranges, not quotes, and not HVAC, electrical, or tax advice. Get several written, itemized estimates from licensed HVAC contractors, and confirm any permit or inspection requirement locally. A different equipment tier, ductwork, or electrical work can move the total well beyond these ranges. Any 25C tax credit is shown separately — verify eligibility at energy.gov / IRS.

FAQ

How much does a single-zone mini-split cost?

Indicatively, a single-zone mini-split runs about $3,000 – $5,000 installed as configured, and up to roughly $5,500 – $12,500 once new ductwork and electrical work are included. Because there is no ductwork and only one indoor head, a single-zone mini-split is the simplest and usually the least expensive heat pump install. Cost still moves with the head's capacity, the line-set length, and any electrical work. These are planning ranges, not quotes — get several local estimates.

What can change the price the most?

Beyond the system itself, the biggest swings come from whether existing ductwork can be reused or must be added, the electrical or panel work the system needs, the equipment brand and tier, and your local labor rates. Toggle ductwork and electrical above to see how much they move the total.

Does the federal 25C tax credit apply?

A qualifying heat pump can earn the federal 25C credit — commonly 30% of cost, up to about $2,000 per year. The calculator can show this as a separate, optional line, but it never folds the credit into the headline price, because eligibility and amounts can change. Confirm current rules at energy.gov / IRS and with a tax professional.
