Cal-Therm Corporation

Cal-Therm Corporation operates from Chino, California, specializing in industrial and commercial mechanical systems rather than typical residential HVAC services. The business holds a 5-star rating from a single review and maintains weekday hours from 7 AM to 5 PM. Service areas include both California and Arizona, with a dedicated Arizona line at 602-859-1530 and the California number at 562-430-7524. The company focuses on specialized infrastructure systems including cryogenic applications, refrigeration, process piping, and sophisticated HVAC duct configurations for commercial and industrial facilities.

The contractor distinguishes itself through expertise in complex mechanical systems that most residential HVAC companies do not handle. Their portfolio includes chilled and hot water systems, steam systems, and specialized process piping for industrial applications. This positions Cal-Therm as a niche provider serving commercial facilities, manufacturing operations, and specialized temperature-control environments rather than standard homeowner needs.

Customer feedback specific to this contractor is limited, with only one review on record. This makes it difficult to extract detailed customer stories or identify technicians by name from verified feedback. Prospective commercial clients seeking industrial cryogenic systems, refrigeration infrastructure, or process piping expertise would benefit from contacting Cal-Therm directly to discuss project-specific requirements.
