The answer to the cost of a ductless HVAC system is that it can vary widely depending on factors like the size of your home, the number of units needed, and your local market. Typically, ductless systems range from $3,000 to $15,000 for a whole-home installation, with the average being around $5,000 to $10,000.
The key factors that influence the cost are the number of indoor air handling units required, the size and efficiency rating of the outdoor compressor unit, the complexity of the installation, and any necessary electrical or structural work. Ductless systems are generally more expensive upfront than traditional central HVAC, but they can provide energy savings and flexibility that make them a worthwhile investment for many homeowners.
