Read the pricing guideYour 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.
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.
