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

Pricing for a 1,500 sq ft home’s mini split depends on your layout and the number of zones. We provide firm pricing after an on-site estimate. Install time can be as little as one day, depending on how many indoor units you need.

Cost drivers to review:

• Single-zone vs multi-zone Mitsubishi system
• Line set length and wall/ceiling placement
• Electrical work and condensate drainage
• Filter and control options
• Access at your Madison home
