Mini Split Cost

How much does a mini split cost?

A pro-installed mini split usually costs $2,000 to $5,000 for one zone, per Angi, and most people pay around $3,000. HomeAdvisor gives the same $3,000 average with a wider $2,000 to $14,500 range once you add more zones. Carrier lists $2,500 to $15,000 or more.

Whole-home systems cost much more. EnergySage says its 2025 marketplace quotes averaged $19,556 after incentives. These are source estimates, not a quote. Your price depends on your home and your installer.

Garage mini split cost

Angi puts the average garage mini split at about $3,500, with most jobs between $2,000 and $9,200. Unit size follows garage size: about 6,000 BTU for a 1-car, 9,000 BTU for a 2-car and 18,000 BTU for a 3-car garage. See the table above.

Garages often need prep first. Angi lists wiring at $1,000 to $2,500, a dedicated circuit at $570 to $1,100 and garage insulation at $1,900 to $7,700. A concrete pad for the outdoor unit runs $4 to $8 per sq ft.

Running a 9,000 BTU unit 8 hours a day in a 2-car garage costs about $5 to $36 a month, per Angi.

Cost by number of zones and size

Each zone adds an indoor unit. Angi lists each extra indoor unit at $400 to $1,800. A garage almost always needs just one zone.

• 2 zones: $1,400 to $7,700 (Angi)
• 3 zones: $1,800 to $9,100
• 4 zones: $2,600 to $10,700
• 5 zones: $4,400 to $12,000
• 12,000 BTU: $700 to $3,200
• 18,000 BTU: $1,000 to $4,200
• 24,000 BTU: $1,100 to $5,200
• 36,000 BTU: $1,800 to $6,000

Installation labor and add-on costs

Labor runs $300 to $2,000 for a single zone and $700 to $3,000 for multi-zone, per Angi. HVAC pros charge $50 to $100 an hour, and most jobs take 2 to 8 hours, per HomeAdvisor.

Permits cost $250 to $400 for the HVAC permit, plus $10 to $500 for each extra permit, like electrical. Common add-ons from Angi:

• Condensate pump: $120 to $280
• Condenser stand: $100 to $210
• Wall bracket: $40 to $100
• Line sets: about $5 per foot

DIY vs pro mini split cost

DIY saves most of the labor, but only with a DIY-rated unit like the MRCOOL DIY that uses pre-charged lines. Standard units need a pro to connect, vacuum and check the lines, and many warranties require a pro install. Angi says full installs are not DIY-friendly without real experience. For electrical work, follow local codes and use a licensed electrician.

Here is an example. A MRCOOL DIY 12K at $1,880 to $2,359 plus a dedicated circuit at $570 to $1,100 lands around $2,450 to $3,460 before permits. Compare that with Angi's $3,500 garage average. The video below shows one owner's DIY install.

Tax credits and rebates

The federal 25C Energy Efficient Home Improvement Credit only covered heat pumps placed in service by the end of 2025, per the IRS. A mini split installed in 2026 does not qualify.

Local utility and state rebates may still apply. Check the ENERGY STAR Rebate Finder with your ZIP code.

How to save on a mini split

A smaller, well-planned job costs less. Insulation helps most in a garage, so start with our garage door insulation kit guide.

• Get 3 written quotes that list the unit, line set, electrical and permits.
• Size it to your garage. Do not oversize.
• Pick one zone for a garage.
• Insulate the garage door and walls first so a smaller unit can keep up.
• Pour the pad or clear the area yourself where your installer agrees.
• Go DIY only with a DIY-rated unit and a licensed electrician for the circuit.

Is a garage mini split worth the cost?

It is worth it if you use the garage often as a gym, shop or hangout and want both heat and AC in one quiet unit. Building a gym? See our best home gym equipment guide.

If you only need winter heat a few days a year, a garage heater costs less up front. Compare options in our best garage heaters guide and how to heat a garage.
