How much does it cost to install a mini split system for a 1500 sq ft house?

There isn’t a one-price answer for a 1,500 sq ft home. Total cost depends on your number of zones, equipment selection, and installation conditions. We start with an in-home consultation and system sizing, then give upfront pricing before any work. In the Dayton area, installations can include single or multi-zone setups with inverter efficiency and smart controls. Our team handles indoor/outdoor placement, refrigerant line hookups, controls setup, testing, and a customer walkthrough.

Cost drivers:

• Number of indoor units (zones)
• Equipment efficiency and smart features
• Line-set length and placement details
• Replacement vs. new install
