Retrofit Service Company Inc.

Retrofit Service Company Inc. has operated from Rancho Cucamonga since 1993, making it one of Southern California's longer-serving commercial HVAC contractors. The company holds a 4.0-star rating across four reviews and specializes in serving office complexes, retail centers, professional buildings, restaurants, religious facilities, and educational institutions throughout the region. All service work is performed by factory-trained, NATE certified technicians who handle both routine maintenance and complex system installations.

What distinguishes Retrofit Service Company from typical residential HVAC shops is their focus on commercial-grade solutions and energy compliance. The company specializes in Title 24 compliant installations, California's strict building energy efficiency code, alongside VRF variable refrigerant flow systems, direct unit replacements for rooftop units, and boiler systems. Their building automation division designs and installs integrated climate control systems that manage efficiency across entire commercial properties. The company also maintains 24-hour emergency availability for urgent HVAC failures.

Customer feedback highlights specific technicians who deliver exceptional service. Priscilla Martinez awarded five stars after working with Hank, describing him as "so professional and very knowledgeable" during her experience. One unrelated review cited driver conduct issues on the freeway, but the company's response to that feedback demonstrates engagement with customer concerns. For commercial property managers in Rancho Cucamonga and across Southern California seeking experienced HVAC partners, the combination of long-standing regional presence and specialized technical expertise positions Retrofit Service Company as a reliable choice.
