Commercial Restaurant Odor Control in Ontario, CA

Odor complaints can hurt reviews, trigger landlord notices, and impact permits. #1 AC Guys designs restaurant odor control that reduces emissions at the hood and at the roof, stabilizes dining room pressure, and stays compliant—all while preserving comfort and energy efficiency.

Engineered Solutions, Not Guesswork

Our process starts with diagnostics: capture velocity checks, duct static readings, airflow balancing, and odor pathway mapping. We then design a layered system that may include enhanced hood filtration, electrostatic precipitators (ESP) for smoke and grease, carbon or specialty media scrubbers for odor molecules, and UV-C/PCO modules for continuous oxidation—applied where they’re most effective.

• Targeted capture at the hood for grease and smoke
• Staged filtration and scrubbing to treat persistent odors
• Demand-control kitchen ventilation to match load and reduce energy
• Make-up air (MUA) balancing to prevent backdrafting and infiltration
• Sealed ductwork and tuned fan curves for quiet, steady performance

Compliance Built In

We design to NFPA 96, California Mechanical Code, health department requirements, and South Coast AQMD nuisance odor considerations. Proper documentation, submittals, and commissioning support help you satisfy inspectors, landlords, and neighboring tenants.

Factory-Trained Expertise

Our team is factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That background helps us integrate odor-control assemblies with modern VRF/ducted systems, rooftop units, and controls without compromising comfort or refrigeration needs.

AC PRO-Ready Parts and Service

We source industry-leading filters, media cartridges, fans, and accessories from trusted suppliers such as AC PRO to keep your system serviceable and cost-effective over its life. That means faster turnarounds, predictable maintenance, and readily available consumables.

What We Deliver

• Odor reduction tailored to your specific cuisine and volume
• Lower risk of neighbor complaints and violations
• Cleaner rooftops and longer fan life through better grease control
• Stable dining room comfort via correct pressure and MUA control
• Energy savings from right-sized exhaust and demand-control strategies

Our Step-by-Step Approach

1) Site assessment and measurements. 2) Odor load modeling by menu and duty cycle. 3) System design with equipment schedules and submittals. 4) Installation coordinated around kitchen hours. 5) Air balancing and commissioning reports. 6) Staff orientation for care and cleaning. 7) Preventive maintenance with media replacement planning.

Technologies We Apply

• Carbon and blended media scrubbers for odor molecules
• ESP for high-efficiency removal of smoke and fine grease
• UV-C/PCO modules for continuous oxidation where appropriate
• Variable-speed exhaust and MUA fans for precise control
• Advanced controls with sensors to match ventilation to cooking load

Because every kitchen is different, we right-size equipment to your hood length, cookline BTU, and stack height. We ensure access panels for service, correct drain routing where needed, and safe electrical isolation for maintenance.
