Commercial Ventilation Design in Pasadena, CA

Engineer‑Led Ventilation Design Built for Pasadena Businesses

#1 AC Guys is a fourth‑generation family business in Los Angeles with 80+ years of engineering experience. We specialize in Commercial Ventilation Design for Pasadena and surrounding communities, delivering systems that protect occupant health, meet stringent codes, and help businesses control operating costs. Our mission is simple and uncompromising: healthy air indoors for a healthy life at work.

Every project starts with a deep engineering review of your building’s use, occupancy, schedules, and heat/contaminant sources. We then apply ASHRAE 62.1 and California Title 24 to right‑size outside air, select filtration, and design ducts, fans, and controls that maintain stable pressurization and airflow under real‑world conditions.

What You Get with Our Commercial Ventilation Design

• Permit‑ready mechanical plans and coordination notes
• Ventilation and heating/cooling load calculations
• Duct layouts, sizes, and pressure drop calculations
• Equipment schedules (fans, ERVs/HRVs, coils, filtration)
• Sequence of operations for controls and sensors
• Title 24 forms and code compliance documentation
• Construction administration support and air balance coordination

From concept to final tuning, we focus on clarity and constructability so contractors can price and build accurately the first time. The result is fewer change orders, smoother inspections, and predictable performance.

Advanced IAQ and Energy Strategies

To help Pasadena companies achieve healthier, more efficient buildings, we employ proven strategies tailored to your occupancy and budget:

• Demand‑controlled ventilation using CO₂ sensors to match outside air to real‑time occupancy
• Energy recovery ventilation (ERV/HRV) to reclaim energy from exhaust air and reduce loads
• MERV 13+ filtration and optional air cleaning layers where risk profiles demand it
• Kitchen, restroom, and specialty exhaust with proper make‑up air and space pressurization
• Low‑noise duct design, vibration control, and balancing plans for quiet operation
• Smart controls, zoning, and scheduling to cut waste during partial occupancy

These methods improve indoor air quality while lowering utility costs, supporting sustainability goals and occupant wellbeing.

AC PRO‑Compatible Integration

Prefer AC PRO‑specified equipment or components? We routinely design around AC PRO‑available products and coordinate with your procurement team or contractor to align selections with performance, budget, and lead times. This flexibility helps streamline sourcing without compromising engineering intent.

Factory‑Trained, Complex‑Project Ready

Our engineers have completed factory training at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). Combined with decades of field coordination, this experience allows us to solve challenging ventilation scenarios in labs, restaurants, multi‑tenant offices, and mixed‑use buildings—where airflows, heat loads, and code requirements are most demanding.

Sectors We Serve in Pasadena

• Office and coworking spaces
• Retail and mixed‑use
• Restaurants, cafés, and commercial kitchens
• Healthcare clinics and wellness studios
• Education and public facilities
• Light industrial and specialty suites

If your facility type isn’t listed, ask us—our engineering‑first approach adapts to unique programs and technical constraints.

Code, Comfort, and Constructability

We design to ASHRAE 62.1 and California Title 24, aligning outside air rates, filtration, and controls with occupancy and use. We coordinate structural, architectural, and electrical needs, plan for service clearances, and provide sequences that commissioning teams can verify. Our drawings emphasize clean routing, accessible equipment, and realistic static pressures for successful balancing.

For tenant improvements, we audit existing systems, document capacities, and modify or add ERVs, fans, or control points to meet new loads—all while minimizing disruption and preserving aesthetics.
