At ON TIME HVAC SF, we specialize in keeping commercial kitchens safe, compliant, and fully operational through expert service in commercial kitchen exhaust and vent systems. Based in San Francisco, CA, we serve restaurants and food service businesses across the Bay Area—including San Mateo (Peninsula) and Oakland (East Bay)—with fast, reliable support from EPA-certified technicians who bring over 10 years of hands-on experience to every job.

We’re a California state-licensed and bonded contractor (C-20 HVAC #1109407), so we understand how critical your exhaust system is to your daily operations. When your vent goes down, your kitchen shuts down—and that’s where we come in.

Why Ventilation Matters

A properly functioning commercial kitchen vent isn’t just about comfort—it’s a health and safety requirement. These systems remove heat, smoke, grease, and airborne contaminants, keeping your workspace breathable and your business compliant. If your commercial kitchen exhaust fails, you risk fire hazards, health code violations, and forced closures.

That’s why we focus on fast diagnostics, accurate air balancing reports, and same-day repairs whenever possible. Our team carries most motors and parts in stock, so we can get your system back without delay.

What We Offer

We provide expert service, repair, and preventative maintenance for commercial kitchen exhaust systems. Our technicians perform air balancing reports, verify proper CFM (cubic feet per minute) performance, and ensure your system meets health department requirements.

We also specialize in CaptiveAire exhaust blower service, walk-in cooler repairs, and commercial refrigeration support. But our core focus is your vent system—because when it fails, everything else grinds to a halt.

Let ON TIME HVAC SF keep your kitchen running smoothly—reach out today to schedule expert service or request an emergency repair.

Emergency Repairs When You Need Them Most

When your commercial kitchen exhaust hood goes down, your entire operation can come to a halt. Health departments require a functioning exhaust system to keep your kitchen open—and downtime means lost revenue, frustrated staff, and unhappy customers.

At ON TIME HVAC SF, we specialize in fast, same-day emergency repairs for commercial kitchen vent systems. Our EPA-certified technicians arrive equipped with most motors and parts in stock, ready to diagnose and resolve issues on the spot. Whether your blower has failed or your system is triggering shutdowns, we act quickly to restore safe, compliant airflow.

We understand the urgency. That’s why we prioritize emergency calls across San Francisco, San Mateo (Peninsula), and Oakland (East Bay), with rapid response times and clear communication from start to finish. If your kitchen is at risk of closure due to exhaust failure, call us now—we’ll get you back in business.

What kind of maintenance do you provide for commercial kitchen exhaust systems?

We offer preventative maintenance services that include CFM measurement and air balancing reports required by local health departments. These services help ensure your system is functioning properly and compliant with regulations. 

Can you help if my exhaust hood isn’t pulling enough air?

Absolutely. Our technicians use specialized tools to measure CFM output and identify airflow issues. We’ll determine whether the problem lies with the motor or other components, and perform repairs or adjustments to restore proper ventilation.

Do you carry parts for same-day repairs?

Yes, we stock a wide range of motors and essential components so we can complete most repairs during the initial visit. This minimizes downtime and helps you avoid extended closures or costly delays.
