Commercial Retail Store HVAC Installation in Orange, CA

Purpose-built HVAC for Retail Environments in Orange

Your customers linger longer and buy more when the store feels just right. As a family business now in its fourth generation, #1 AC Guys turns that goal into reality with engineered HVAC solutions focused on comfort, air quality, and reliability for retail spaces in Orange, CA.

Our mission is healthy indoor air that supports healthy lives at work and in the community. We deliver this through smart system design, meticulous installation, and attention to the details that matter on busy sales floors.

What We Install

• Rooftop packaged units with economizers for big-box and multi-tenant retail
• VRF/VRV systems for precise zoning in boutiques and multi-level spaces
• Conventional split systems and ductless mini-splits for targeted comfort
• Make-up air and energy recovery ventilation where additional fresh air is needed

Our engineers are factory-trained by Mitsubishi Electric, Fujitsu, Midea, Gree, and Haier, so we integrate equipment to the manufacturer’s best practices from day one.

Our Retail-Focused Process

1) On-site assessment and load calculations: We survey your shell, ceiling plenum, electrical, roof structure, and air distribution to model real-world loads—people, lighting, and display heat—to size equipment accurately.

2) System design and zoning: We map traffic patterns, entrances, fitting rooms, checkout lines, stock areas, and heat-gain zones to create smart zoning that keeps hotspots under control and avoids cold aisles.

3) Air quality and ventilation: We design for MERV-13-capable filtration, demand-controlled ventilation with CO2 sensing, and balanced outside air to meet California code and keep the air fresh without wasting energy.

4) Controls and visibility: Simple, staff-friendly thermostats or centralized building controls with scheduling, remote access, and alerts to protect comfort and prevent energy waste.

5) Code compliance and permits: We handle Title 24 documentation, CALGreen requirements, mechanical permits, and inspections, keeping your project on track and compliant.

6) Construction logistics: We coordinate crane lifts, curb adapters, sealing and flashing, fire-smoke damper integration, and dust control. When needed, we work nights or off-hours to minimize sales interruptions.

7) Commissioning and turnover: Full start-up, airflow verification, test and balance, and fine-tuning. You get a clean, organized install, training for your team, and documentation for your records.

Designed for Every Retail Format

• Boutiques and salons: Quiet VRF or ductless for ultra-smooth comfort with minimal visual impact.
• Strip centers and inline stores: Efficient rooftop units with smart zoning for storefront heat loads and back-of-house areas.
• Big-box and anchor tenants: High-capacity RTUs with economizers, advanced filtration, and robust controls to handle crowds and long hours.
• Historic or tight plenum spaces: Compact multi-port systems and thoughtful duct routing to preserve aesthetics while upgrading performance.
