Commercial Retail Store HVAC Installation in Fullerton

Why Fullerton Retailers Choose #1 AC Guys

We are a fourth‑generation, family‑owned HVAC team with more than 80 years of engineering experience focused on healthy, reliable comfort. Our factory‑trained engineers have hands‑on training with leading manufacturers — Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier (China) — so your store gets the right equipment, correctly sized and expertly installed. We understand retail: sales depend on shopper comfort, quiet operation, low energy costs, and zero surprise downtime.

• Design‑build and value engineering for boutiques, inline stores, showrooms, and big‑box spaces

• Rooftop packaged units (RTUs), split systems, heat pumps, VRF/VRV, and ductless mini‑splits
• Demand‑controlled ventilation, economizers, and energy‑saving controls/thermostats
• Indoor air quality: MERV 13+ filtration, HEPA options, UV‑C, and dedicated outdoor air systems

Engineered for California Compliance and Efficiency

From SEER2/EER2 standards to Title 24 and CalGreen requirements, we design systems that meet or exceed California codes while lowering your utility bills. Our team helps you pursue available utility incentives and tax advantages and can provide energy modeling to compare RTU vs. VRF or heat pump solutions. The result: a compliant installation that reduces operating costs without sacrificing comfort or acoustics.

Open‑Store and Fast‑Track Installations

Retail rarely stops. We plan installations around your traffic patterns and peak hours to minimize disruption. Options include night and weekend work, phased change‑outs, temporary cooling, and dust/noise containment. Our site leads maintain clean work zones, protect finishes and merchandise, and communicate milestones daily so your team always knows what’s next.

Healthy Air, Healthy Life — Indoor Air Quality That Sells

Comfort drives dwell time and conversion. We design ventilation and filtration to deliver fresh, clean air that helps reduce allergens and odors while keeping CO2 and humidity in check. Ask about MERV 13+ upgrades, HEPA add‑ons, UV‑C for coils, and dedicated outdoor air systems that meet ASHRAE ventilation targets for retail environments.

Systems We Install

• High‑efficiency rooftop packaged units with economizers and curb adapters
• VRF/VRV for multi‑zone stores, tenant improvements, and expansions
• Ductless mini‑splits for back‑of‑house, stockrooms, fitting rooms, and kiosks
• Heat pumps for electrification goals and low‑ambient performance options
