Engineered right the first time

With over 80 years of engineering excellence spanning four generations, our family team thrives on large and complex commercial projects. Factory-trained with Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier, we bring disciplined commissioning practices to every exhaust system. We service all major commercial fan brands, including Greenheck, CaptiveAire, Twin City Fan & Blower, and Loren Cook—so your system is supported from design through lifecycle care.

Local codes, permits, and compliance

We handle permitting and inspections and design to meet or exceed: California Title 24 energy standards, NFPA 96 for commercial cooking ventilation, applicable ASHRAE ventilation guidelines, and local Pasadena Building & Safety requirements. From grease-rated duct routing to fire-rated clearances, rooftop curb details, seismic fastening, and electrical coordination, we document every step for a smooth sign-off.

Smarter controls and lower operating costs

We apply variable frequency drives (VFDs), EC motors, and demand-controlled ventilation to match exhaust to real-time load, cutting energy use and noise while extending equipment life. Integration with building management systems (BMS) and interlocks with hood, make-up air, fire suppression, and gas safety valves are executed and tested during commissioning to protect people and property.

Industries we serve

Restaurants and food halls, hotels and hospitality, offices and retail, education and healthcare, laboratories and light manufacturing, warehouses and parking structures, and multifamily common areas. Whether it’s a new kitchen hood line in Old Pasadena or a garage exhaust upgrade near the Playhouse District, we tailor each system to your building and business goals.
