# Mini-Split Sizing & Cost

> For 2 zone, the current national model estimates $9,642, with a planning range of $7,231 to $13,980. Adjust project size and quality, then enter a ZIP to apply a metro or state wage factor to labor only. Materials, labor, permits, disposal, data dates, and sources are shown separately.

## National default result

- **Typical:** $9,642
- **Planning range:** $7,231 to $13,980
- **Default quantity:** 2 zone
- **Per unit:** $4,821 per zone
- **Components:** materials $5,340, labor $3,902, permits $250, disposal $150

The national default is a planning estimate, not a contractor quote. A ZIP changes the labor component using a metro or state OEWS wage multiplier; it does not change materials.

## Inputs

- **Zones:** default 2 zone
- **Material / quality:** default standard

## Calculation

    material = baseline material rate × quantity × material index change × quality
    labor = baseline labor rate × quantity × labor index change × ZIP wage multiplier
    subtotal = material + labor + permit + disposal
    range = subtotal × documented low/high multipliers

Material index: PPIFIS, latest period 2026-07-01, change 2.69%.  
Labor index: PPIFIS, latest period 2026-07-01, change 2.69%.

## Main price drivers

- Equipment capacity and efficiency
- Ductwork or electrical changes
- Number of zones
- Climate and design load
- Refrigerant-line and permit work

## Questions and direct answers

### What does this mini-split sizing & cost include?

The estimate separates materials, labor, permit, and disposal using the quantities shown. It excludes financing, hidden damage, and optional work not selected.

### How does the ZIP adjustment work?

ZIP is matched to a metro when available; otherwise a state wage factor is used. Only labor changes. Materials remain tied to national price indices.

### Is this a contractor quote?

No. It is a planning estimate. Confirm scope, code requirements, and price with licensed local contractors before committing funds.

### Why is the range wider than the typical cost?

The low and high multipliers capture ordinary variation in finish level, access, site conditions, and contractor availability.

### How current is the estimate?

The baseline is dated 2026-01-01. Index observations and their latest periods are displayed with every result.

### Can I use the result for a budget?

Use it as an early planning range and include contingency. A site-specific quote remains necessary for a committed budget.
