Combined Engineering Services

Combined Engineering Services operates as an HVAC contractor serving Riverside and San Bernardino, California. With three decades of hands-on experience in heating, cooling, and refrigeration systems, this contractor provides both residential and commercial property owners with comprehensive mechanical solutions. The company maintains its primary presence in the Riverside metropolitan area, offering services that span routine maintenance through complete system installations. Potential customers can reach the office directly at (909) 479-5392 to discuss their specific heating and cooling needs.

What distinguishes Combined Engineering Services from neighboring contractors is their specialized focus on commercial refrigeration alongside standard HVAC offerings. The business handles walk-in cooler repair, a niche service that many general HVAC companies in the region do not offer, supporting restaurants, grocery stores, and other businesses that depend on reliable cold storage. Their service portfolio also includes professional duct cleaning for improved indoor air quality, heat pump installation for year-round temperature efficiency, and insulation upgrades that reduce energy consumption. This combination of traditional heating and cooling work with commercial refrigeration expertise creates a one-company solution for property managers who otherwise might juggle multiple service providers.

The company emphasizes transparent communication and lasting customer relationships as core business values. Their service approach centers on delivering work that reflects careful attention to detail, with technicians who take the time to explain system conditions and recommend appropriate solutions rather than pushing unnecessary upgrades. Customers working with Combined Engineering Services deal with the same knowledgeable team members who understand local climate challenges and how different system configurations perform in Southern California conditions.
