Why Commercial Ventilation Matters in Santa Rosa
Here’s the thing: poor ventilation doesn’t just make your building uncomfortable. It creates real problems that hurt your business.
Think about the last time you walked into a stuffy office building or felt the heat blast from a restaurant kitchen. That’s not just unpleasant—it’s costing money. Your HVAC system works harder when ventilation isn’t balanced properly. Employees get tired when CO2 levels creep up. Health inspectors start asking questions when kitchen exhaust doesn’t meet code.
And in Sonoma County, we’ve got specific challenges other areas don’t deal with. Wildfire smoke events mean your ventilation system needs proper filtration. Hot summer days in Bennett Valley require makeup air systems that won’t send your cooling costs through the roof. Wineries need humidity control that protects corks while managing fermentation areas.
How Commercial Ventilation Systems Actually Work
Most people think ventilation is simple—fans bring in fresh air, other fans push out stale air. But commercial systems are more sophisticated than that.
Your building needs balanced airflow. Too much exhaust without enough supply air creates negative pressure, which makes doors hard to open and pulls unconditioned air through every crack. Too much supply without adequate exhaust causes positive pressure, pushing conditioned air out of the building and wasting energy.
Here’s what happens in a properly designed system: Fresh outdoor air enters through rooftop units or wall-mounted supply fans. That air gets filtered (MERV-rated filters remove particles), conditioned to the right temperature, and distributed through ductwork to where you need it. Meanwhile, exhaust fans remove contaminated air from specific areas—kitchens, bathrooms, industrial processes. The whole system is balanced so CFM (cubic feet per minute) calculations match your building’s needs.
Advanced systems use energy recovery ventilators that transfer heat between incoming and outgoing air. During summer, hot outdoor air gets pre-cooled by the exhaust air before entering your building. In winter, cold outdoor air gets pre-warmed. This saves serious money on energy bills.
Services We Provide
Commercial Ventilation Installation
We design and install complete ventilation systems for new construction and major renovations. Our process starts with airflow calculations based on your building’s square footage, occupancy levels, and specific operations. We size equipment correctly—not too small (which fails to ventilate properly) or too large (which wastes energy and money).
Installation includes rooftop ventilation units, exhaust fans, makeup air units, ductwork (galvanized, stainless steel, or flexible depending on your needs), dampers, diffusers, grilles, and control systems. Everything gets commissioned and tested to confirm it meets design specifications.
For restaurants and commercial kitchens, we install Type 1 and Type 2 hood systems with proper makeup air coordination. Manufacturing facilities get industrial exhaust systems with the right CFM capacity for process emissions. Office buildings receive energy recovery ventilators that meet ASHRAE Standard 62.1 requirements while controlling operating costs.
Ventilation Repair & Maintenance
When your ventilation system stops working right, problems multiply fast. Kitchen exhaust failure means you can’t operate. Manufacturing ventilation issues create OSHA compliance problems. Office building ventilation that’s out of balance drives up energy costs and generates employee complaints.
We handle everything from fan motor replacements and belt adjustments to control troubleshooting and damper repairs. Common repairs include fixing failed variable frequency drives, replacing worn-out exhaust fans, sealing duct leaks, and repairing or replacing smoke and fire dampers.
Our maintenance programs prevent these problems before they shut down your operations. We inspect and clean exhaust fans, change filters, lubricate bearings, test controls, measure airflow, check duct integrity, inspect dampers, and calibrate sensors. Regular maintenance catches small issues before they become expensive emergencies.
Air Balance Testing (TAB Services)
Testing, adjusting, and balancing is the final step that makes everything work right. We use calibrated instruments to measure actual airflow at each diffuser and grille. Then we adjust dampers and fan speeds until every area gets the right amount of air.
This isn’t optional—California Title 24 and most health department inspections require certified TAB reports. We measure static pressure, verify CFM delivery, test building pressurization, and document everything with detailed reports that pass inspections.
For restaurants, air balance testing confirms your kitchen hood captures and exhausts all cooking emissions. For office buildings, it verifies every space meets minimum ventilation rates. For warehouses, it makes sure hot spots get adequate cooling and air circulation.
Who We Serve in Santa Rosa & Sonoma County
Restaurants & Commercial Kitchens
Downtown Santa Rosa restaurants, winery tasting rooms, and food service establishments throughout Rohnert Park and Petaluma depend on us for kitchen hood ventilation that meets Sonoma County health department requirements. We install exhaust systems that handle grease-laden vapor, coordinate makeup air so your HVAC system isn’t fighting negative pressure, and provide the air balance reports health inspectors require.
Your hood needs to capture cooking emissions without overworking your cooling system. We design systems with the right capture velocity and airflow to keep kitchens comfortable while meeting code.
Wineries & Tasting Rooms
Wine Country operations have unique needs. Fermentation areas need ventilation that controls CO2 levels without creating temperature swings. Barrel rooms require humidity management that prevents corks from drying out. Tasting rooms need proper airflow for guest comfort without disturbing wine aromas.
We’ve worked with wineries throughout Healdsburg, Windsor, and Sebastopol to create ventilation solutions that protect wine quality while meeting building codes and creating pleasant experiences for visitors.
Manufacturing & Industrial Facilities
Santa Rosa’s business parks along Highway 101 house manufacturers and industrial operations that need robust ventilation for worker safety. We install industrial exhaust systems that remove process emissions, fumes, dust, and heat. These systems meet OSHA air quality requirements and help you avoid citations during safety inspections.
Variable air volume systems give you precise control over different production areas. Demand control ventilation with CO2 sensors reduces energy waste in spaces with changing occupancy.
Warehouses & Distribution Centers
Large facilities need whole building fans and high-capacity exhaust systems that manage heat without excessive energy costs. We install rooftop units, supply fans, and exhaust fans sized for buildings with high ceilings and open floor plans.
Proper ventilation prevents hot spots near loading docks, improves air circulation in storage areas, and creates comfortable conditions for workers moving product all day.
Office Buildings & Professional Spaces
Buildings in Montgomery Village, Rincon Valley, and throughout Santa Rosa’s business districts need ventilation that keeps employees productive. We design systems that meet minimum outdoor air requirements (0.06 CFM per square foot as a baseline, adjusted for occupancy) while controlling energy costs.
Dedicated outdoor air systems separate ventilation from temperature control, giving you better indoor air quality without overworking your HVAC equipment.
Medical Offices & Healthcare Facilities
Healthcare spaces require precise ventilation control for infection prevention. We install systems that maintain proper air changes per hour, create negative pressure in exam rooms when needed, and use MERV-13 or higher filtration to remove airborne contaminants.
Retail Stores & Shopping Centers
Coddingtown Mall and Santa Rosa Plaza retailers need comfortable shopping environments. We provide ventilation solutions that manage customer comfort while controlling the operating costs that affect your bottom line.
Meeting California Title 24 & ASHRAE Requirements
California has strict ventilation requirements, and they’re not suggestions. Your building needs to comply with Title 24, Part 6 energy code and Title 24, Part 4 mechanical code, which reference ASHRAE Standard 62.1.
What does this actually mean? Every occupiable space needs minimum outdoor air based on floor area and occupancy type. California requires 130% of ASHRAE 62.1 minimum rates—meaning if ASHRAE calls for 100 CFM, California requires 130 CFM. This higher rate improves indoor air quality and earns points toward LEED certification if you’re pursuing that.
You also need MERV-13 air filters on all ducted systems supplying outdoor air. These filters are much more effective at removing fine particles than the MERV-8 or MERV-11 filters used in the past. During wildfire smoke events, MERV-13 filtration makes a real difference in indoor air quality.
Building pressurization matters too. California code requires balancing supply and exhaust so you don’t create problems with uncontrolled infiltration or exfiltration.
We stay current with these requirements and handle all permit coordination with City of Santa Rosa building departments. You get systems that pass inspection the first time.
Common Ventilation Problems We Fix
Insufficient Fresh Air: Employees complain about stuffiness, CO2 levels creep above 1,000 ppm, people get drowsy in afternoon meetings. This happens when ventilation systems are undersized or economizers aren’t working properly.
Excessive Energy Bills: Your PG&E costs seem too high for the building size. Often this means the ventilation system is bringing in way more outdoor air than needed, or heat recovery equipment has failed, or controls aren’t working right.
Hot or Cold Spots: Some areas are always too warm or too cold despite HVAC adjustments. Usually this indicates supply air isn’t reaching those spaces because of duct problems or improperly adjusted dampers.
Odor Migration: Smells from one area (kitchens, bathrooms, manufacturing processes) spread to areas where they don’t belong. This means negative pressure is pulling air the wrong direction through the building.
Failed Health Inspections: Restaurant kitchens can’t pass inspection because hood exhaust CFM doesn’t meet requirements, or offices fail indoor air quality testing because outdoor air delivery is too low.
OSHA Complaints: Manufacturing facilities receive citations for inadequate ventilation in areas where workers are exposed to fumes or dust. This requires immediate remediation to avoid fines and liability.
Why Proper Ventilation Saves Money
You might think ventilation is all cost and no benefit, but that’s backwards. Poor ventilation costs way more than proper systems.
Think about it this way: When ventilation isn’t balanced, your HVAC equipment runs harder and longer than it should. That’s wasted energy every single day. When employees get sick more often because indoor air quality is poor, you’re losing productivity and paying for sick days. When health inspectors shut you down because exhaust systems don’t meet code, you’re losing revenue for every day you can’t operate.
Good ventilation systems with energy recovery pay for themselves. Heat recovery ventilators and energy recovery ventilators capture 60-80% of the energy that would otherwise be lost in exhaust air. In a commercial building, that adds up to thousands of dollars per year in reduced heating and cooling costs.
Demand control ventilation adjusts outdoor air delivery based on actual occupancy. Instead of running full ventilation all the time, the system scales back when spaces are empty or lightly occupied. Occupancy sensors and CO2 monitoring control this automatically.
Variable frequency drives on fan motors let you ramp speed up or down instead of running full blast constantly. VFDs typically reduce fan energy consumption by 30-50% compared to older systems.

Frequently Asked Questions (FAQs)
How often does commercial ventilation equipment need maintenance?
Most systems need service every 3-6 months depending on how hard they work. Restaurant kitchen exhaust systems should be checked quarterly because they handle grease and run constantly. Office building systems can often go 6 months between services. Manufacturing and industrial exhaust needs quarterly inspection because process emissions create buildup faster. Regular maintenance prevents unexpected breakdowns and keeps systems running efficiently.
What's the difference between Type 1 and Type 2 kitchen hoods?
Type 1 hoods are required over cooking equipment that produces grease-laden vapors—fryers, griddles, char-broilers, ovens. These hoods have grease filters and connect to exhaust ductwork designed to handle grease. Type 2 hoods are for heat and steam only—over dishwashers, steam tables, pasta cookers. They don't need grease filters or special duct construction. Health departments are strict about using the right type for each appliance.
How do I know if my building has enough outdoor air ventilation?
The most reliable way is having a qualified technician test actual airflow and compare it to calculated requirements based on ASHRAE 62.1 and California Title 24. Warning signs of inadequate ventilation include complaints about stuffiness, drowsiness in meetings, increased sick days, visible moisture on windows, lingering odors, or dust buildup. CO2 monitors can help too—levels consistently above 1,000 ppm indicate insufficient outdoor air.
Can I just open windows instead of installing mechanical ventilation?
For most commercial buildings in California, no. Building codes require mechanical ventilation because you need reliable, consistent outdoor air delivery regardless of weather conditions. Natural ventilation through windows doesn't work when it's too hot or too cold outside, doesn't provide filtration against wildfire smoke or pollen, and can't be measured or controlled to meet code requirements. Some buildings can use a combination approach, but commercial kitchens, healthcare facilities, and most other occupancy types require mechanical systems.
What happens during an air balance test?
Our technician arrives with calibrated instruments to measure airflow at every supply and return grille in your building. We check fan speeds, measure static pressure in ductwork, test damper positions, and verify building pressurization. Then we adjust dampers and fan speeds until every space receives the right amount of air according to design specifications. You receive a certified report documenting all measurements and adjustments. This report is required for most building permits, certificate of occupancy, and health department approvals.
Why are my energy bills so high if ventilation is working?
Working and working efficiently are different things. Your ventilation system might be delivering air but wasting energy doing it. Common causes include: economizers stuck in the wrong position bringing in excessive outdoor air, heat recovery equipment that failed so you're losing all the energy in exhaust air, incorrectly programmed controls running systems at full capacity when they should be scaled back, or duct leaks letting expensive conditioned air escape before it reaches occupied spaces. A thorough system evaluation identifies where energy is being wasted.
How long does commercial ventilation equipment last?
Typical lifespans are: exhaust and supply fans 15-20 years, rooftop units 15-20 years, ductwork 25+ years if properly maintained, controls and sensors 10-15 years, dampers 15-20 years. Heat recovery equipment 15-20 years. These are averages—equipment that's maintained properly lasts longer, while systems that are neglected fail sooner. Operating environment matters too. Kitchen exhaust fans handling grease wear faster than office building supply fans. Coastal locations with salt air see more corrosion. Quality of installation makes a big difference in equipment longevity.
