You and your HVAC team will likely start by examining the correct mini-split configuration for your home. Tiny homes or those with an open floor plan may only require a single-zone system, while homes that need multiple thermostats will require more. The mini-split’s location will also determine the product's cost. Keep in mind that these prices do not include installation costs.

|---|---|
| Single-zone | $2,000–$5,000 |
| Multi-zone | $5,500–$15,000+ |

|---|---|
| 6,000 | $470–$1,670 |
| 9,000 | $625–$2,405 |

The advantage of a multi-split or multi-zone system is that it allows you to have different cooling areas in your home. Up to five indoor units can be attached to each outdoor unit; most systems have at least one indoor unit. Additional units can cost between $500 and $1,800. More powerful condensers are needed to run more than five units at a time, which can increase costs.
When deciding how many rooms you need cooled in your home, you can choose between a single-zone and a multi-zone mini-split system. An HVAC professional can assess each room's square footage to ensure the right fit. More zones lead to higher costs, with single-zone systems ranging from $2,000 to $5,000 and five-zone systems from $11,500 to $14,000 or more.
| Number of Zones | Average Cost |
|---|---|
| 1 | $2,000–$5,000 |
| 2 | $5,500–$9,000 |
| 3 | $8,500–$9,100 |
| 4 | $10,000–$12,000 |
| 5 | $11,500–$14,000+ |
The efficiency of a mini-split unit significantly impacts its overall cost. A higher Seasonal Energy Efficiency Ratio (SEER) rating means lower monthly energy costs due to increased efficiency. You should factor this in when choosing a unit, especially in a region with extreme temperatures, where a higher SEER-rated system may be cost-effective.
Energy-efficient units save money in the long run and often even qualify for utility rebates and government tax credits. However, they may come with a higher upfront cost. Be sure to balance your budget with long-term savings when making a decision.
A ductless mini-split AC system comprises three main parts: an outdoor condensing unit, inside air units, and refrigerant coolant lines to connect everything. They can be bought as a kit, or each part can be purchased individually as needed.

| Part | Average Cost |
|---|---|
| Outdoor unit | $1,045–$5,750 |
| Indoor unit(s) | $525–$1,1880 |
| Refrigerant lines | $5.25 per ft. |
| Installation kit | $315–$525 |
HVAC contractors in Baltimore, MD, charge $75 to $175 per hour. Since the city’s housing stock includes many older rowhomes and historic properties, installations may require more labor to account for drilling and routing conduit through brick or masonry. These homes also have more walls and closed-off rooms, so they may require more zones, further adding to installation labor needs.
Mini-split installations also require your contractor to obtain a permit through Baltimore County’s Department of Permits, Approvals, and Inspections. Permit fees start at $35.
Mini-split installations in older homes in Baltimore, MD, may require electrical upgrades, such as running new circuits or upgrading panels. Electricians in Baltimore, MD, charge $60 to $120 per hour, and electrical panel replacements in the area range from $500 to $2,000.
A mini-split installation in Baltimore, MD, can add value when it improves the home's comfort and energy efficiency. The return on investment (ROI) averages 30%, and returns tend to be strongest in homes without existing ductwork or spaces that are difficult to heat and cool with conventional equipment. In older rowhouses, finished upper floors or attics, and home additions, for example, mini-split systems improve year-round comfort and add zoned control without requiring extensive remodeling to retrofit ductwork.
