Commercial Ventilation Design in Calabasas

#1 AC Guys is a fourth-generation, family-owned HVAC engineering firm serving Calabasas with precise, code-ready Commercial Ventilation Design. With 80+ years of engineering expertise, our mission is simple and uncompromising: healthy air at work for a healthier life. We engineer outside air and exhaust systems that protect occupants, streamline energy costs, and stand up to inspections and real-world operation.

Engineered for compliance and health

Our designs meet or exceed California Title 24 and ASHRAE 62.1/90.1 requirements, aligning outside air rates, filtration, and controls with the unique needs of each space. We implement demand-controlled ventilation using CO2 sensing where appropriate, apply MERV 13+ filtration (and HEPA or UV-C options when required), and optimize duct geometry to lower static pressure and fan energy. The result is cleaner indoor air, stable comfort, and a quieter acoustic profile.

We bring factory training directly into your project from Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That manufacturer-level insight helps us match equipment and accessories to your load profile, controls strategy, and budget—without guesswork.
When schedules are tight, we frequently specify and source AC PRO commercial-grade ducts, diffusers, dampers, curbs, and accessories to keep Calabasas projects moving.

What we design

• Outside air and exhaust systems for offices, retail, restaurants, fitness studios, and medical suites
• Dedicated outdoor air systems (DOAS), ERV/HRV integration, and airside economizers
• Low-loss ductwork, VAV/VVT strategies, and quiet air distribution
• Kitchen makeup air and grease exhaust coordination with hood suppliers
• Warehouse and light industrial ventilation, spot exhaust, and heat mitigation
• Tenant improvements, core-and-shell, and retrofit modernization

Our process

• Discovery and survey: usage, occupancy, existing equipment, and constraints
• Ventilation calculations: outside air per ASHRAE 62.1, diversity, and zoning
• Load and energy modeling: right-sized equipment and fan power targets
• Duct design: SMACNA-based sizing, pressure mapping, and acoustics
• Equipment selection: solutions informed by training with Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier
• Controls strategy: CO2-based DCV, economizer logic, schedules, and alarms
• Documentation: sealed drawings, equipment schedules, and submittal packages
• Permitting support: Title 24 forms, compliance reports, and plan-check response
• Construction coordination: shop drawing review and field clarifications
• Commissioning and TAB coordination: balance plans, punchlist, and owner training

AC PRO in your specification

To meet project schedules in Calabasas and greater Los Angeles County, we often specify AC PRO commercial-grade ducts, fittings, diffusers, dampers, curbs, and related accessories. This helps maintain availability and consistency during submittals, procurement, and installation—without locking you into a single equipment brand. We align components with the chosen rooftop units, DOAS, ERV/HRV, and controls to deliver a cohesive, code-compliant package.

Local expertise, regional reach

Based in Southern California, we focus on Calabasas while serving Los Angeles County and nearby areas including Orange County, Ventura County, and Western Riverside County. We understand local plan-check expectations, seismic bracing requirements, utility programs, and the microclimates that influence ventilation and economizer performance.

Healthy air, smoothly delivered

Every drawing set is prepared with construction and maintenance in mind: thoughtful access for service, clear labeling, and balanced airflow that stands up to TAB. We communicate early with architects, GCs, and subs to avoid clashes, reduce change orders, and shorten closeout.

Ready to move forward? Whether you need a new commercial ventilation design, a retrofit that boosts IAQ and efficiency, or a peer review to resolve a plan-check comment, #1 AC Guys is your Calabasas partner. Let our fourth-generation engineering team design a clean-air, code-ready system—with AC PRO availability and manufacturer-trained insight—to keep your project on time and your occupants breathing easier.
