Highland Air LLC

Highland Air LLC operates from Oak Park, California, delivering heating and cooling solutions to homeowners across the region. With 66 customer reviews generating a 4.9-star average rating, the company has built a steady reputation for reliable service. Owner Shai Zimon leads service calls, handling installations and repairs for residential properties throughout the local community.

What distinguishes Highland Air is the direct involvement of the owner on every job. Reviewers consistently highlight Shai's hands-on approach, he arrives on time, explains what he's doing, and ensures systems run correctly before leaving. The company handles minisplit installations, ongoing AC maintenance, and diagnostic work, with customers noting Shai often suggests troubleshooting steps over the phone to avoid unnecessary service calls. This Transparent, owner-operated model sets the company apart from larger operations where technicians rotate.

Customers share specific experiences that illustrate the company's service style. Ben Middlemas provided his own minisplit and Shai installed it with careful attention to positioning and operation. For Laura's home, Shai responded quickly to service requests over multiple years, offering honest advice about whether a full visit was needed. Michelle Carson's studio tenants use their minisplit through summer and winter extremes and report efficient performance. One 2023 review documents concerns about a system installed during a remodel, noting the owner struggled with diagnostics and accountability.
