Why Commercial Ventilation Matters More in Healdsburg
Here’s the thing about Healdsburg: you’re not dealing with typical commercial ventilation needs. You’ve got wine country dust settling in HVAC systems during harvest. You’ve got restaurants and tasting rooms that need to handle serious cooking loads without turning the dining area into a sauna. You’ve got historic buildings around Healdsburg Plaza that weren’t built with modern ventilation in mind. And you’ve got California’s strict Title 24 energy compliance requirements on top of everything else.
Poor ventilation shows up fast in commercial spaces. Employees complain about headaches or fatigue. Customers comment on stuffy air or lingering odors. Your energy bills creep higher as your HVAC system works overtime trying to compensate. Health inspectors start asking questions about your kitchen exhaust. Or worse, you discover your building pressurization is off and you’re pulling exhaust air back into the space instead of sending it outside where it belongs.
We see this all the time: a business owner calls us after ignoring small ventilation problems for months, and now they’re facing a compliance issue or a breakdown during their busiest season. Don’t be that business. Let’s talk about what proper commercial ventilation actually means.
Commercial Ventilation Systems We Install and Service
Restaurant and Commercial Kitchen Exhaust Systems
If you’re running a restaurant near Mill Street or operating a commercial kitchen anywhere in Healdsburg, your kitchen hood exhaust system isn’t optional. It’s mandated by California code, and for good reason. Grease-laden air is a serious fire hazard, and commercial kitchens produce enough heat to make the space unbearable without proper ventilation.
We design and install Type I hood systems (for grease-producing equipment) and Type II hoods (for heat and steam). Every installation includes proper make-up air, because here’s what most business owners don’t realize: if you’re exhausting 2,000 CFM of air through your kitchen hood, that air has to come from somewhere. Without make-up air, you create negative pressure that makes doors hard to open, pulls in outside air through every crack, and can even cause your water heater or furnace to backdraft.
Our commercial kitchen ventilation work includes grease duct systems in stainless steel, fire dampers rated for high-temperature applications, and variable speed exhaust fans that adjust based on cooking load. We follow ASHRAE 62.1 standards and California Mechanical Code requirements because passing inspection on the first try matters when you’re trying to open or remodel.
Winery and Tasting Room HVAC
Healdsburg sits in the heart of wine country, and we’ve worked with enough wineries to know that your HVAC needs are completely different from standard retail. Tasting rooms need humidity control so corks don’t dry out. Wine storage areas need precise temperature stability. Production facilities need serious ventilation during fermentation season when CO2 levels spike.
For tasting rooms in Russian River Valley or Alexander Valley, we install energy recovery ventilators that bring in fresh air without losing all your conditioned air. During wildfire season, we add MERV 13 or higher filtration to keep smoke and particulates out. For wine cellars, we work with dedicated cooling systems that maintain 55-60°F and 50-70% humidity year-round.
The worst thing you can do is treat a wine storage area like a regular office space. Standard HVAC creates temperature swings that affect wine aging. We design systems specifically for wine preservation, and yes, we understand the difference between barrel storage (which tolerates some temperature variation) and bottle storage (which needs consistency).
Indoor Air Quality and Building-Wide Ventilation
Many commercial buildings in Healdsburg’s downtown area have mixed-use setups: retail on the ground floor, offices or apartments above. These spaces need balanced ventilation that accounts for different usage patterns. You can’t just exhaust air without bringing fresh air in, and you can’t just bring fresh air in without controlling humidity and temperature.
We install demand-controlled ventilation systems that adjust based on actual occupancy. When your restaurant fills up for dinner service, CO2 sensors trigger increased ventilation automatically. When your office empties out in the evening, the system dials back to save energy. This approach meets California Title 24 requirements while cutting your utility costs.
For spaces near Westside Road or Old Redwood Highway where traffic exhaust is a concern, we add multi-stage filtration. MERV-rated filters catch particles, and activated carbon handles odors and VOCs. During wildfire season (which seems to happen more often now), proper filtration keeps your indoor air quality acceptable even when the AQI outside is in the unhealthy range.
Rooftop HVAC and Commercial Air Handling
Most commercial buildings rely on rooftop units for heating and cooling. What people don’t always realize is that proper ventilation is built into these systems through outdoor air dampers and economizers. When those components fail or get misconfigured, you end up recirculating stale air instead of bringing in fresh air.
We service and install packaged rooftop units from 3 tons up to 25+ tons, with particular attention to outdoor air intake and exhaust. Your system should be bringing in the right amount of outside air based on occupancy, filtered appropriately, and mixed with return air in the right proportions. Get this wrong and you’re either wasting energy conditioning excessive outdoor air or failing to meet ventilation code requirements.
For larger commercial buildings near North Street or along Healdsburg Avenue, we design VAV (Variable Air Volume) systems that provide zone-level control. Different areas get different amounts of conditioned air based on their actual needs. Conference rooms get a ventilation boost when occupied. Storage areas get minimal ventilation. The system adapts, which translates to lower energy costs and better comfort.
Make-Up Air Systems
This is something most business owners have never heard of until a building inspector or HVAC contractor mentions it. Make-up air units supply heated or cooled outdoor air to replace air that’s being exhausted. Commercial kitchens need them. Manufacturing facilities need them. Any space with significant exhaust requirements needs them.
Without proper make-up air, you create negative building pressure. Doors become hard to open. Cold drafts sneak in through every gap. Exhaust systems don’t work right because they’re fighting the negative pressure. And in the worst cases, you get backdrafting from gas-fired equipment, which is a carbon monoxide hazard.
We size make-up air units based on actual exhaust volumes, not guesses. For restaurants in Healdsburg’s climate, we typically use direct gas-fired units that temper incoming air without huge energy penalties. For applications that need cleaner supply air, we use indirect-fired or heat pump units. The goal is bringing in the volume of outdoor air you need at a temperature that doesn’t shock employees or drive up your gas bill.
Healdsburg’s Commercial Ventilation Challenges
Working in Healdsburg means dealing with specific issues you don’t see in other parts of California.
Wildfire Smoke: Recent years have shown us that wildfire season is a real concern. When the Camp Fire or Glass Fire smoke rolled through, buildings with poor filtration became nearly unusable. We now recommend MERV 13 or MERV 16 filters for commercial spaces, along with bypass filtration during severe smoke events. Some clients have added air purifiers with HEPA filtration for critical areas.
Wine Country Dust: Harvest season in Dry Creek Valley and Alexander Valley means dust in the air. That dust gets pulled into HVAC systems, coating coils and clogging filters. Regular maintenance during and after harvest season prevents this from becoming a major problem. We’re talking monthly filter changes instead of quarterly during peak dust months.
Historic Building Constraints: Properties around Healdsburg Plaza and throughout downtown were built decades before modern ventilation codes existed. Adding commercial ventilation to these spaces means working within structural limitations. Low ceilings, no space for ductwork, limited roof access for exhaust fans. We’ve gotten creative with ductless mini-split systems, low-profile ducting, and strategic fan placement to make code-compliant ventilation work in challenging buildings.
Summer Heat and Fire Season: Healdsburg summers get hot, and when you combine that with wildfire smoke, outdoor air intake becomes tricky. You need ventilation for indoor air quality, but bringing in 95-degree smoky air isn’t great either. Energy recovery ventilators help by precooling incoming air with outgoing air, and smart controls can temporarily reduce outdoor air intake during extreme conditions (while staying above minimum code requirements).
California Title 24 Compliance: This is the big one. California’s energy code requires commercial buildings to meet specific ventilation rates based on occupancy type, with 130% of ASHRAE 62.1 minimums in most cases. You need MERV 13 filters on outdoor air intake. You need economizer controls on rooftop units over a certain size. You need demand-controlled ventilation for high-occupancy spaces. We handle all of this during design and installation so your system passes inspection.
Our Commercial Ventilation Process
Here’s how we approach commercial ventilation projects in Healdsburg:
1. Assessment: We start by understanding your space. What’s the business type? How many people occupy the space? What equipment generates heat or pollutants? What are the existing building systems? We calculate required ventilation rates based on California Mechanical Code and ASHRAE standards.
2. Design: Every commercial space is different. We design systems that meet code requirements while fitting within your budget and building constraints. This includes CFM calculations, equipment selection, ductwork layout, and control strategies. For restaurants, we coordinate kitchen hood exhaust with make-up air and dining area HVAC. For wineries, we design around temperature and humidity requirements. For retail and office spaces, we focus on energy efficiency and comfort.
3. Installation: Our technicians handle the complete installation, from sheet metal fabrication to electrical connections to final balancing. We work around your business schedule because we know you can’t just shut down for a week. Most installations happen during off-hours or in phases that minimize disruption.
4. Testing and Balancing: This step separates professional installations from mediocre ones. We measure actual airflows at every supply and exhaust point, compare them to design specs, and adjust until everything is within tolerance. Static pressure gets balanced so you’re not wasting fan energy. Outdoor air intake gets verified to meet code requirements. The system works the way it was designed to work.
5. Maintenance: Commercial ventilation systems need regular attention. Filters get changed (monthly to quarterly depending on conditions). Belts get inspected. Motors get lubricated. Controls get calibrated. We offer preventive maintenance programs that keep your system running reliably and help you avoid emergency breakdowns.

Frequently Asked Questions (FAQs)
How much does commercial ventilation installation cost in Healdsburg?
There's no one-size-fits-all answer because every project is different. A simple exhaust fan installation for a small office might run $2,000-$5,000. A complete commercial kitchen hood system with make-up air for a restaurant could be $25,000-$75,000 or more. Rooftop HVAC unit replacement ranges from $8,000-$25,000 depending on size and features.
We provide detailed written estimates after assessing your specific needs. The estimate includes equipment, labor, materials, permits, and any required balancing or testing. No surprise charges, no "we found additional problems" upcharges unless we actually discover something that wasn't visible during the initial assessment.
How often should I service my commercial ventilation system?
Most commercial systems need attention quarterly at minimum. Restaurants and commercial kitchens need monthly service during busy seasons. The schedule depends on your business type, operating hours, and environmental factors.
During maintenance visits, we're changing filters, cleaning coils, checking belts and bearings, testing controls, measuring airflows, and inspecting exhaust hoods and ductwork for grease buildup. Regular maintenance prevents breakdowns, extends equipment life, keeps your system running efficiently, and maintains compliance with health and safety codes.
What's the difference between a Type I and Type II commercial hood?
Type I hoods handle grease-laden air from cooking equipment like fryers, griddles, and charbroilers. They require grease filters or extractors, fire suppression systems, and special grease duct construction. The ductwork has to be stainless steel or properly sealed galvanized steel, with accessible cleanout points. This is what most restaurants need over their main cooking line.
Type II hoods handle heat and moisture but not grease. Think dishwashers, ovens, and steamers. They still need to exhaust outside, but the requirements aren't as strict since there's no grease fire hazard. Many commercial kitchens need both types of hoods depending on their equipment layout.
Do I really need make-up air for my commercial kitchen?
Yes. California Mechanical Code requires make-up air when you're exhausting more than 400 CFM from a single hood or 800 CFM total from all hoods. But honestly, you probably need it even below those thresholds if you want your kitchen to function properly.
Without make-up air, you get negative building pressure that causes all sorts of problems. Doors are hard to open. Cold air gets sucked in through every gap and crack. Your dining room HVAC can't keep up because it's constantly fighting infiltration. The hood exhaust system doesn't work efficiently because it's fighting the negative pressure. Make-up air solves all of this by providing a dedicated source of replacement air at a controlled temperature.
How do I know if my ventilation system is code-compliant?
That's what building inspectors check during occupancy permits and health inspections. If you're not sure about your current system, we can perform a ventilation assessment that measures actual airflows and compares them to California Title 24 and ASHRAE 62.1 requirements.
Common code violations we find: insufficient outdoor air intake, lack of make-up air, improper exhaust ductwork, non-functioning economizers, inadequate filtration, and incorrect CO2 sensor placement. Most of these can be corrected without tearing out the entire system, but it's easier to do it right from the start.
Can you help with ventilation during building remodels or tenant improvements?
Absolutely. This is actually when it's easiest to add proper ventilation because walls are open and ductwork can be routed before finishes go in. We work with architects, general contractors, and building owners during the planning phase to design systems that meet code, fit within the budget, and work with the building's structural and aesthetic requirements.
For tenant improvements in downtown Healdsburg or along Healdsburg Avenue, we handle all mechanical, electrical, and plumbing coordination for the HVAC system. We pull permits, schedule inspections, and make sure everything passes the first time. You don't want HVAC issues holding up your certificate of occupancy when you're ready to open.
What about wildfire smoke and indoor air quality?
This has become a major concern in recent years. Standard HVAC filters (MERV 8 or lower) don't catch the fine particles in wildfire smoke. We recommend upgrading to MERV 13 filters at minimum, or MERV 16 if your system can handle the increased static pressure.
For businesses that need to stay open during smoke events, we can add air purifiers with HEPA filtration for critical areas, install energy recovery ventilators that reduce outdoor air intake while maintaining adequate ventilation, and set up controls that temporarily reduce outdoor air intake during extreme AQI conditions (while staying above minimum code requirements). It's about balancing indoor air quality with fire code requirements and energy efficiency.
