Inland Empire heat makes ductless cooling a necessity

Our Services

Comprehensive Mini Split AC Installation in the Inland Empire

Mini split AC systems solve a problem central AC cannot — targeted cooling for spaces without existing ductwork. In the Inland Empire, that means room additions, garage conversions, older Murrieta and Temecula homes built before central air was standard, and commercial offices that need zone control. Our HVAC team handles single-zone and multi-zone ductless installations. View all cooling service options.

Single-Zone Mini Split Installation

One indoor head unit paired with one outdoor compressor — ideal for a room addition, master bedroom, or space that gets more sun than the rest of the home.

Multi-Zone Ductless Systems

One outdoor compressor powering 2–5 indoor units in different rooms — each zone controlled independently for homes or offices that need flexible cooling.
