How Much Does Ductless Air Conditioning Cost to Install?

Ductless mini-split systems are an alternative to traditional central AC that eliminate the need for ductwork installation. Various factors influence ductless air conditioner installation costs, but many homeowners enjoy enhanced home comfort and long-term savings on energy consumption. Explore how ductless air conditioning works, and get a tailored installation estimate from Dugan Air.

What is Ductless Air Conditioning and How Does It Work?

Ductless air conditioning, also known as a mini-split system, is a cooling system that doesn’t require ductwork to draw in or distribute air throughout your home. Instead, ductless air conditioning systems consist of an outdoor condenser and one or more indoor air handlers that distribute cool air directly into HVAC zones. The indoor air handlers, or heads, are mounted onto the floor, wall, or ceiling.

Mini-split systems use the same technology as heat pumps and AC units to cool air — an evaporator coil in each air handler houses refrigerant and absorbs heat from the indoor air. Outside, the condensing unit compresses and releases the heat. The cooled refrigerant travels back through the lines while the air handler utilizes the blower fan to distribute cooled air to the space. 

One outdoor unit can connect to multiple indoor units. Conduits containing refrigerant lines and electrical wires connect the air handlers to the outdoor unit. Each indoor head features a thermostat and independently controls its zone. Many systems also provide heating, reversing this process to warm your home. 

What is the Average Cost to Install Ductless Air Conditioning?

The cost of a ductless air conditioning system depends on several factors, but they average from $5,000 to $10,000 with installation. Multi-zone systems reflect the high end of the price range and can cost from $10,000 to $20,000, depending on the overall system size and number of zones. 

Your HVAC contractor can provide a precise estimate following their assessment of your home and its cooling needs.

Factors that Affect the Cost of Ductless Heating and AC Installation

The number of zones or indoor units, system size, efficiency ratings, and other factors influence the upfront price of a ductless air conditioning system, but rebates and incentives can help offset these costs. Understanding these variables helps you choose the ideal system for your home.

Number of zones

Since each indoor air handler can usually only accommodate one room or zone, the number of zones or rooms will impact the cost. If you need to cool four rooms in your home, it’s likely you’ll need four indoor units. Most outdoor units can accommodate up to eight heads — after that, you may need multiple condensers, which adds to the overall price.

Other factors also influence the number of zones needed. For example, open floor plans may require multiple heads for expansive rooms. 

System size and capacity

The cooling capacity of a ductless AC is measured in British Thermal Units (BTUs). Most homes require about 20 BTUs per square foot, and a 500 to 600 square-foot space needs approximately 10,000 to 12,000 BTUs. Your home’s actual cooling load depends on insulation quality, the number of windows and doors, and the local climate. An HVAC technician can accurately calculate your home’s exact needs to ensure proper sizing.

Brand

Different brands offer mini-split systems at various price points. Some are more affordable than premium brands, for example, but may have limited reliability, efficiency, and longevity. Some Mitsubishi models, for instance, have more premium price points but provide cost savings in terms of superior energy efficiency, advanced features, enhanced convenience, and more comprehensive warranties.

Efficiency rating

Seasonal energy efficiency ratio (SEER) ratings measure how efficiently a mini-split system cools a space. Higher SEER ratings usually translate to increased upfront costs, but investing in an energy-efficient unit can lead to long-term savings on your electricity bills.

Installation complexity

Various factors influence installation complexity. For example, wall-mounted units are usually the simplest and least costly to install, while ceiling cassettes or floor-mounted units may require more involved labor. Other complexity factors include:

• Long refrigerant lines or electrical wiring.
• Electrical panel upgrades.
• Add-on smart home features.
• Accessibility challenges.

Rebates and incentives

Government programs and utility companies often provide rebates and tax incentives for homeowners who upgrade to energy-efficient systems, such as ductless ACs. These incentives help offset the upfront cost.

Is It Worth Installing a Ductless Air Conditioner?

Ductless air conditioning provides several advantages that make it a worthwhile investment for many homeowners.

Energy efficiency and utility savings

Leaky ducts in central AC systems can account for up to 30% of cooling energy costs. In comparison, ductless mini-splits eliminate energy losses associated with leaky ductwork. Ducted central AC and heat pumps don’t usually exceed about 26 SEER, but mini-splits can achieve up to 35 SEER. Over time, this energy efficiency reduces utility bills.

Versatility

Because each head operates independently, you can set different temperatures in each zone. This capability allows for improved comfort and energy efficiency since reducing cooling in unused areas helps lower consumption. Many ductless AC systems are also heating systems, so they provide year-round comfort.

Quiet operation

Ductless systems are significantly quieter than traditional HVAC systems, benefiting homes with higher noise sensitivity.

Easy installation

Without ductwork, mini-split installation is significantly faster and less disruptive than central AC. Technicians drill small holes to run conduit lines and can mount the units quickly. This is ideal for older homes or home additions where ductwork installation may be less practical.
