Mini Split Installation Cost Guide: Pricing and Labor
Forbes Home puts a single mini-split zone at $2,000 to $7,800 to install, including the outside compressor. Fixr gives a national average of $6,357 for a ductless cooling system in the home. Cost depends on the number of zones, the indoor unit style, and the wiring your home needs.

HomeGuide also lists wall-mounted units at $2,500 to $5,000 per zone, floor-mounted at $3,000 to $5,000, and ceiling cassettes at $3,500 to $6,000. Angi reports that a single-zone system in St. Louis, MO starts at $1,000 to $5,000. The sources use different baselines, so treat the numbers as a spread rather than a single price.
Single-zone vs. multi-zone systems
If more rooms need their own air handler, Bob Vila says extra units typically cost $450 to $1,600 each, or you can install a larger condenser. Angi puts additional units at $380 to $1,710. This Old House reports an average of $11,000 for split AC installation, depending on the number of zones, system size, and installation complexity. Its survey found homeowners who installed a ductless mini-split paid an average of $8,221 for the replacement.
Labor vs. materials
Bob Vila says hiring an HVAC technician for most mini-split installations costs $300 to $1,500. Fixr lists HVAC mechanics at $86 to $157 per hour depending on the area. The copper refrigerant lines between the indoor and outdoor units run about $7 per foot, per Bob Vila.
If your home needs new circuits, Bob Vila says an electrician usually charges $50 to $100 per hour, while Fixr puts an electrician at $101 to $183 per hour. Angi estimates $410 to $1,590 more on the total for wiring and panel upgrades. See our electrical cost guides for panel work.
DIY vs. hiring a pro
A mini-split involves high-voltage wiring and refrigerant lines, so most homeowners hire a licensed HVAC contractor and electrician. Permit costs vary by location, and Forbes Home sets them at $250 to $400. Our HVAC cost guides cover related systems.
Ways to save
- Compare quotes: Collect written bids from several licensed contractors and compare labor and equipment lines.
- Match the style to the budget: Wall-mounted units start lower than ceiling cassettes and concealed duct units in HomeGuide’s figures.
- Plan the line run: Because lines are priced per foot, placing the outdoor unit close to the indoor one keeps that item small.
- Check electrical needs early: Ask whether your panel and circuits can handle the system before you accept a bid.
How to get an accurate quote
Ask for an on-site visit and a written quote that lists the model numbers, indoor unit styles, labor, permits, and any electrical work. Confirm the installer’s license and insurance, and ask who will apply for permits. A quote that bundles everything into one number makes it hard to compare bids, so request the lines separately.
What changes the price
- Number of indoor zones and air handlers required
- Mounting style of indoor units, such as wall, floor, or ceiling cassette
- Total system cooling capacity and tonnage
- Electrical service panel capacity and wiring upgrades
- Local building permit requirements and municipal fees
