GJR,LLC

GJR LLC has served the Rancho Cucamonga community as a licensed HVAC contractor, earning a 4.8-star rating across 17 client reviews. The company handles residential and light commercial heating and cooling needs throughout the Inland Empire, including surrounding cities such as Ontario and Fontana. Owner Jason leads service calls personally, bringing certified expertise to every job site.

What distinguishes GJR LLC from neighboring contractors is their dual capability in both traditional HVAC systems and commercial refrigeration.

This commercial-refrigeration niche, combined with honest diagnostic practices that reviewers consistently praise, positions GJR as a practical choice for property managers and homeowners alike.

Customer stories from reviews reveal specific scenarios where GJR delivered. Michael Burnley needed an emergency condenser repair with a freon recharge, describing the service as fast and effective. Lyle Teng appreciated that Jason suggested additional fixes without pressuring him, calling the technician thorough and a very nice person. Rosario Sanchez noted the contractor works to resolve problems in the shortest time possible, highlighting the company's emphasis on efficient turnaround.
