Read the pricing guideMini-split installation questions, answered
How much does mini-split installation cost in Phoenix?
Your installation price depends on the equipment, number of indoor units, electrical work, line-set length, and access to the installation area. Start with our free online estimate, then have the project scope confirmed for your space. Ask which installation items and warranty terms are included before choosing a system.
Can a ductless mini-split cool a garage or home gym?
A ductless system provides independent temperature control for a garage, workshop, or home gym. Equipment selection should account for floor area, ceiling height, insulation, garage doors, sun exposure, and how you use the space. A site assessment helps determine an appropriate size and placement.
Can you install mini-splits in a casita or home addition?
Yes. Core Comfort HVAC installs ductless mini-split systems for spaces such as casitas and home additions. A single-zone system serves one area; a multi-zone design can serve several areas with separate indoor units. The layout and cooling needs determine which approach fits the project.
Which Arizona cities do you serve?
Our priority service areas include Phoenix, Peoria, Chandler, Buckeye, and Carefree, with service throughout the surrounding Phoenix metro area. Contact us with your installation address to confirm scheduling and project availability.
What should I ask before scheduling installation?
Ask about system sizing, indoor and outdoor unit placement, electrical requirements, line-set routing and covers, drainage, and any work outside the quoted scope. Confirm the installation schedule and warranty terms, and request a walkthrough of the controls and routine care when the work is complete.
