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

Costs for a 1,500 sq ft mini split vary by system size, number of zones, and site conditions. A technician will confirm pricing after an in-home assessment. CM Heating installs Mitsubishi single-zone or multi-zone systems with 2–8 indoor units. Electrical upgrades or difficult line-set runs can affect price. Local rebates can reduce upfront cost: Snohomish PUD up to $800, PSE $800, and Seattle City Light up to $600. Financing options are available for qualified applicants.
