Commercial & Industrial Exhaust Systems in Pasadena

#1 AC Guys brings an engineering‑first approach to commercial and industrial exhaust systems in Pasadena. Our mission is healthy indoor air for healthy living and productive workspaces. We plan every detail—from capture velocity and duct losses to fan curves, vibration control, and make‑up air balance—so your facility stays safe, comfortable, and compliant.

Comprehensive exhaust solutions we design, install, and service

• Commercial kitchen grease exhaust (UL 762) with hoods, grease ducts, spark arrestors, and rooftop upblast fans
• Make‑up air units (MAU) with gas/electric/heat pump options, filtration upgrades, and tempered air controls
• Laboratory and specialty process exhaust, fume hoods, and corrosion‑resistant duct systems
• Manufacturing and welding fume extraction, heat and smoke relief, and process ventilation
• Parking garage exhaust with CO/NO2 sensors and demand‑controlled ventilation for energy savings
• High‑plume stacks and dilution strategies to protect neighboring properties and meet AQMD guidelines
• Warehouse and distribution center exhaust with destratification and pressure control
• Dust collection tie‑ins and local source capture (where permitted), plus make‑up air integration
• Boiler/mechanical room combustion air and relief ventilation

Our engineering‑driven process

Every Pasadena project starts with a site assessment and airflow audit. We model loads, select fans to the duty point, and right‑size ducts and fittings to lower static pressure and noise. Controls may include VFDs, pressure sensors, and interlocks to synchronize exhaust with make‑up air. We deliver permit‑ready submittals, coordinate with other trades, and commission the system so performance matches design intent.

• Field survey, capture testing, and airflow calculations
• Fan selection, vibration isolation, and curb/roof coordination
• Duct routing, grease containment, and access door placement
• Controls and safety interlocks, including fire suppression interfaces where required
• Test, Adjust, Balance (TAB) and training for your staff

Codes, standards, and compliance

We design to California Mechanical Code and the International Mechanical Code, implement NFPA 96 for commercial cooking operations, and follow OSHA best practices. Where applicable, we apply UL 705/762 listings, SCAQMD guidelines, local Pasadena and Los Angeles County plan review requirements, and California Title 24 energy standards. Our documentation streamlines permits and inspections.

AC PRO component integration
