April 15, 2025

If you’re considering a Day & Night ductless mini split AC for your Northwestern home, one of the biggest questions you’ll probably have is, “How much will it cost to install a ductless system?” 

Ductless mini splits are an excellent choice for energy-efficient, targeted cooling, but the total cost can vary depending on several factors. 

Day & Night breaks down the costs associated with purchasing and installing a Day & Night ductless mini split system so you can make an informed decision.

Understanding the Mini Split Install Cost Variants

The total cost of installing a Day & Night ductless mini split AC includes the unit’s price, installation labor, additional materials, and potential upgrades. The ductless installation estimates below are national averages and include many variables. Be sure to Find a Dealer near you for an accurate ductless mini split installation quote.

1. Cost of the Mini Split System

The price of a Day & Night ductless mini split AC depends on the system’s size (BTU capacity), efficiency rating (SEER), and whether you’re installing a single-zone or multi-zone system.

  • Single-Zone Mini Split: A single indoor unit (head) connected to one outdoor unit.
  • Multi-Zone Mini Split: Multiple indoor air handlers (up to 8) connected to a single outdoor unit, allowing for customized temperature control in different rooms.

Here’s a general price range for each unit/head:

  • Up to 9,000 BTUs (400-500 sq ft): $600 to $2,300 
  • Up to 12,000 BTUs (550 sq ft): $700 to $3,200
  • Up to 18,000 BTUs (1,000 sq ft): $1,000 to $4,200 
  • 24,000+ BTUs (over 1,000 sq ft): $1,100 to $5,200+

Higher SEER ratings and inverter technology increase efficiency but also raise upfront costs. However, these features save money on energy bills in the long run.

2. Ductless Installation Labor Costs

Professional installation is crucial for the optimal performance and longevity of your mini split system. Labor costs vary based on the complexity of the job, the number of indoor units, and the specific installation requirements.

  • Basic single-zone installation: $1,500 to $3,000
  • Multi-zone installation: $3,000 to $8,000+

A straightforward install (with an easily accessible location for both the indoor and outdoor units) will be on the lower end of the cost range, whereas complex installations—such as drilling through thick walls or running long refrigerant lines—will be more expensive.

3. Additional HVAC Labor and Electrical Work

Factors that can add to your installation price include, but are not limited to:

  • Mounting hardware and brackets
  • Electrical work (new circuit, breaker upgrade, wiring)
  • Refrigerant line set (longer than standard length)
  • Condensate drain line and pump (if required)

4. Optional Upgrades for Ductless Systems

While optional, certain add-ons can enhance your system’s efficiency and convenience but do add to the final invoice total. These add-ons can include:

  • Smart thermostat or Wi-Fi control
  • Surge protector to prevent electrical damage
  • Extended manufacturer warranty

5. Other Factors That Influence Ductless System Costs

Several variables can affect the overall installation price:

  • Home Layout: If your home requires complex installation, such as long refrigerant line runs or tricky mounting locations, expect higher labor costs.
  • Local Labor Rates: Prices vary by region due to differences in labor costs and permit fees.
  • Efficiency Rating: Higher SEER-rated systems cost more upfront but offer long-term energy savings.
  • Permits and Inspections: Some areas require permits for mini split installations, adding $100 – $500 to your costs.
  • Rebates and Incentives: Check for local utility rebates and federal tax incentives, which could reduce your upfront costs.

Is a Ductless Mini Split Worth the Investment?

A Day & Night ductless mini split AC offers several long-term benefits that help balance out the upfront expense:

  • Energy Efficiency: Mini splits use inverter technology to adjust power consumption based on demand, reducing energy costs. Without the need for ductwork, there is also less risk of energy waste caused by air leaks.
  • Zoned Comfort: Each indoor unit can be set to different temperatures, allowing for personalized comfort.
  • Easy Installation: Compared to traditional central HVAC systems, ductless mini splits require less invasive installation, especially in homes without ductwork.
  • Improved Air Quality: Many models come with advanced filtration systems that help reduce allergens and pollutants. Plus, without ducts, there is no risk of polluted air entering your duct system through tears.
