The answer to 'ductless system installation cost' is that the cost can vary significantly depending on several factors. Ductless or mini-split HVAC systems are generally more expensive to install than traditional ducted systems, but the exact cost will depend on the size of your home, the number of indoor and outdoor units needed, the complexity of the installation, and your local labor and material costs.
Generally, you can expect to pay anywhere from $3,000 to $15,000 or more for a ductless system installation, with most homeowners spending between $5,000 and $12,000. The cost is higher for larger homes or those requiring multiple indoor units. Additionally, the brand, efficiency rating, and any necessary electrical or structural modifications can all impact the final price.
