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

There isn’t a single price for a 1,500 sq ft home. Mini‑split installation cost depends on how many indoor heads (zones) you need and the equipment selected. We give straightforward, upfront pricing after an in‑home assessment in Franklin, Bellingham, and nearby towns.

What drives cost:

• Number of zones and total BTU capacity
• Line‑set length and placement challenges
• Mounting type (wall, floor, or ceiling cassette)
• Electrical work needed for the outdoor unit
• Brand/efficiency features and accessories
