Open Calculator →Commercial kitchen ventilation is one of the largest capital expenses in a restaurant build-out — and one of the least understood. The hood itself is only part of the story. By the time you add ductwork, exhaust fans, make-up air, fire suppression, electrical work, and installation labor, the total system cost for a mid-size restaurant kitchen ranges from $15,000 to $50,000+. Here's the complete breakdown so you can budget accurately and avoid surprises.
Component-by-Component Cost Breakdown
1. Exhaust Hood — $3,000 to $15,000
The hood is the visible part — the stainless steel canopy mounted above your cooking line. Price depends on length, type, and features:
| Hood Type | 4-Foot | 8-Foot | 12-Foot | 16-Foot |
|---|---|---|---|---|
| Wall-mounted canopy (Type I) | $2,500–$3,500 | $4,500–$6,500 | $7,000–$10,000 | $9,500–$14,000 |
| Island canopy (Type I) | $3,500–$5,000 | $6,500–$9,000 | $10,000–$14,000 | $13,000–$18,000 |
| Condensate hood (Type II) | $1,500–$2,500 | $2,800–$4,500 | $4,500–$7,000 | $6,000–$9,000 |
Type I hoods (for grease-producing equipment) include baffle filters and are substantially more expensive than Type II hoods (for steam/condensate from dishwashers and ovens). Most kitchens need at least one Type I hood.
Premium features that add cost: LED lighting ($200-$500), integrated make-up air plenum ($1,000-$3,000), demand-controlled ventilation sensors ($800-$2,000), custom stainless finishes ($500-$1,500).
2. Ductwork — $2,000 to $8,000
Grease-rated ductwork connects the hood to the rooftop exhaust fan. Commercial kitchen duct must be welded (not snap-lock) 16-gauge or 18-gauge steel. Cost depends on the distance from hood to roof and the number of turns:
- Straight vertical run (single story): $2,000-$3,500
- With horizontal runs and elbows: $3,500-$6,000
- Multi-story building or long horizontal chase: $5,000-$8,000+
- Roof curb and weather cap: $300-$800
Every elbow adds cost (material plus labor) and increases static pressure, which means you may need a larger exhaust fan. A good kitchen designer minimizes duct runs and turns during the floor-plan stage — changes after construction are 5-10x more expensive.
3. Exhaust Fan — $1,000 to $5,000
The exhaust fan mounts on the roof (upblast) or occasionally at the end of a horizontal duct run (utility set). Rooftop upblast fans are the standard for commercial kitchens because they pull grease-laden air up and out.
| CFM Rating | Fan Cost | Typical Application |
|---|---|---|
| 1,500-3,000 CFM | $1,000–$2,000 | Small cafe, food truck commissary |
| 3,000-5,000 CFM | $2,000–$3,500 | Mid-size restaurant, single hood |
| 5,000-8,000 CFM | $3,000–$4,500 | Full-service restaurant, long cooking line |
| 8,000-15,000 CFM | $4,000–$6,000 | Large commercial kitchen, multiple hoods |
Variable-speed fans with VFDs (variable frequency drives) cost $500-$1,500 more but reduce energy consumption by 30-50% during low-demand periods. In most markets, the VFD pays for itself within 12-18 months through energy savings.
4. Make-Up Air Unit — $3,000 to $10,000
The make-up air (MUA) unit replaces the air exhausted from the kitchen. This is the component most often underbudgeted or omitted entirely — a costly mistake.
| MUA Type | Cost Range | Notes |
|---|---|---|
| Direct-fired (heat only) | $3,000–$7,000 | Most common; 92-95% efficient |
| Indirect-fired (heat only) | $4,000–$8,000 | Cleaner air, lower efficiency |
| Rooftop with cooling | $8,000–$15,000 | Required in hot climates |
| MUA ductwork distribution | $1,500–$4,000 | Additional to unit cost |
Don't skip the MUA. A kitchen without proper make-up air will have negative pressure issues, uncomfortable conditions, higher energy costs, and potential code violations.
5. Fire Suppression System — $3,000 to $8,000
All Type I hoods must have an automatic fire suppression system — typically a wet chemical (UL 300) system that protects the hood, ductwork, and cooking equipment. This is non-negotiable for code compliance and insurance.
- Basic system (single hood, standard cooking line): $3,000-$5,000
- Extended system (multiple hoods or long cooking line): $5,000-$8,000
- Additional nozzles for each piece of equipment: $200-$400 each
- Semi-annual inspection and recharge: $200-$400 per visit
Popular systems include Ansul R-102, Kidde Kitchen Guard, and Pyro-Chem PCL. They're all UL 300 listed and functionally similar. Your fire suppression contractor will typically recommend the brand they're certified to install.
6. Installation Labor — $3,000 to $12,000
Installation labor is often the single largest line item, especially in retrofit projects. You'll need:
- Sheet metal installer: Hood mounting, ductwork fabrication and installation ($75-$120/hour)
- Electrician: Fan wiring, interlock wiring, demand control ventilation ($85-$130/hour)
- Plumber/gas fitter: MUA unit gas connection ($80-$120/hour)
- Roofer: Roof penetration and curb installation ($500-$1,500)
- Fire suppression tech: System installation and testing ($1,500-$3,000)
New construction is substantially cheaper than retrofit. Cutting through an existing roof, building a chase through an occupied floor, or working around existing utilities can double installation labor.
Total System Cost: Three Scenarios
| Component | Small Cafe (4-ft hood) | Mid-Size Restaurant (10-ft hood) | Large Kitchen (16-ft hood) |
|---|---|---|---|
| Hood | $3,000 | $7,500 | $13,000 |
| Ductwork | $2,000 | $4,000 | $7,000 |
| Exhaust fan | $1,200 | $3,000 | $5,000 |
| Make-up air | $3,500 | $6,000 | $12,000 |
| Fire suppression | $3,000 | $5,000 | $7,500 |
| Installation | $3,500 | $7,000 | $11,000 |
| Total | $16,200 | $32,500 | $55,500 |
Annual Operating and Energy Costs
The upfront cost is only part of the picture. Operating costs accumulate year after year:
| Cost Category | Annual Range |
|---|---|
| Electricity (exhaust fan + MUA fan) | $2,400–$8,000 |
| Gas (MUA heating) | $1,200–$4,000 |
| Filter cleaning/replacement | $300–$800 |
| Duct cleaning (required annually) | $400–$1,200 |
| Fire suppression inspection (semi-annual) | $400–$800 |
| Belt and bearing maintenance | $200–$500 |
| Total annual operating | $4,900–$15,300 |
The energy cost is the largest ongoing expense. A 5,000 CFM exhaust fan running 14 hours a day (typical restaurant hours) at $0.12/kWh consumes approximately $3,000-$4,000 in electricity per year. Adding demand-controlled ventilation (DCV) that slows the fan when cooking activity is low can reduce this by 30-50%.
Ways to Reduce Costs
- Design early: Plan ventilation during the architectural phase, not after construction starts. Moving a wall to shorten a duct run saves far more than it costs.
- Invest in DCV: Demand-controlled ventilation sensors ($800-$2,000) that adjust fan speed based on cooking activity pay for themselves in 12-18 months.
- Right-size the system: An oversized hood wastes money on equipment and energy every day. Use actual CFM calculations, not rules of thumb.
- Get 3+ bids: Ventilation installation quotes vary by 40-60% between contractors. Get at least three bids from mechanical contractors experienced in commercial kitchens.
Size and Price Your System
Every kitchen is different. Equipment lineup, hood type, building height, and climate all affect both the CFM requirements and the cost. Use our calculator to size your ventilation system based on your actual equipment and get a realistic cost estimate for budgeting and bid evaluation.
