Retail Store HVAC Installation in Ontario, CA

Why #1 AC Guys for Ontario Retail HVAC

We are a fourth‑generation family of engineers with 80+ years of engineering experience, focused on commercial HVAC that keeps shoppers comfortable and products safe. Our mission is healthier indoor air for healthier lives—delivered with precise design, quality equipment, and code‑compliant execution.

AC PRO Solutions, Engineered for Retail

We work expertly with AC PRO equipment to match the realities of retail: changing occupancy, open ceilings, long operating hours, strict comfort expectations, and the need to protect inventory. Whether you operate a boutique, chain storefront, or big‑box retail, we align capacity, airflow, ventilation, and controls with your floor plan and business goals.

Factory‑Trained Team

Our engineers and installers have trained at the factories of Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That depth of product understanding helps us integrate AC PRO solutions with advanced systems—VRF/mini‑split, ducted and ductless zones, and high‑efficiency rooftop units—while maintaining reliability and serviceability.

Design‑Build Process That Reduces Risk

• Discovery: Site survey, electrical review, roof/structural considerations, and merchandising constraints.
• Engineering: ACCA‑based load calculations, duct and diffuser layouts, ventilation strategy (economizers/DCV), and acoustic planning.
• Compliance: Title 24 documentation, CALGreen alignment, permit set preparation, coordination with landlord/GC and AHJ.
• Installation: Clean, coordinated scheduling with minimal downtime, safety‑first practices, and merch protection.
• Commissioning: Airflow balancing, controls setup, sensor calibration, and performance verification.

Systems We Install

• Rooftop Units (RTUs) with economizers and demand‑control ventilation.
• Ducted split systems for back‑of‑house and sales floor zones.
• VRF and heat pump solutions for precise zoning and high efficiency.
• Ductless systems for spot cooling (cash wraps, stockrooms, offices).
• Advanced controls: smart thermostats, BMS integration, scheduling, and remote monitoring.

Healthy Air, Happy Shoppers

Retail depends on clean, comfortable air. We specify filtration and ventilation strategies that help reduce dust, odors, and pollutants while keeping temperature and humidity in the ideal range. Options include higher‑MERV filtration, balanced ventilation, and demand‑controlled ventilation based on CO₂ levels—engineered for comfort and energy savings.

Energy and Code Compliance

Our designs are built around Title 24 and local code requirements. Expect right‑sizing that prevents short cycling, proper duct sealing and insulation, verified airflow, and the controls your store needs to meet compliance without sacrificing comfort. We can also advise on utility incentive pathways when available.

Installation With Minimal Disruption

We protect your customer experience. Staged deliveries, debris control, and coordinated crane lifts keep your operation running. When needed, we schedule off‑hours or phased work so you can stay open.

Commissioning and Documentation

We finish with a thorough commissioning process: airflow testing, controls programming, and performance checks. You receive as‑built documentation, equipment registers, maintenance schedules, and warranty information for clear long‑term management.

Post‑Install Support

• Planned maintenance programs tailored to retail hours and seasons.
• Filter changes, coil cleaning, belt checks, and controls tuning for efficiency.
• Priority response for warranty and service needs.
