A make up air system typically costs $1,500-$15,000 installed, while larger commercial kitchen systems can exceed $30,000. Make up air system cost depends mainly on airflow capacity, heating method, ductwork, electrical work, controls, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Residential system installed | $1,500 | $4,500 | $9,000 | Basic unit paired with a powerful range hood |
| Commercial kitchen installed | $5,000 | $15,000 | $35,000+ | Price rises with airflow, heat, and controls |
| Equipment only | $500 | $2,500 | $10,000+ | Capacity and heating options change price |
| Typical airflow rate | $3 | $8 | $20+ | Approximate equipment cost per CFM, not installed |
Installed prices for residential and commercial systems
For a typical home, a basic 400-800 CFM unit costs about $1,500-$4,500 installed when duct runs are short and no major electrical upgrades are needed. A heated residential system may reach $3,000-$9,000. For a restaurant, a 1,000-3,000 CFM system commonly falls between $8,000 and $25,000 installed; large or complex projects can cost more.
Most straightforward residential projects land near $3,000-$6,000, while commercial kitchen projects often start above that range. These estimates assume standard access and typical U.S. labor, not unusual roof work, long duct routes, or major code corrections.
Assumptions: Standard equipment, ordinary access, and no extensive structural or electrical upgrades.
What fan, duct, heater, and controls add to the quote
Equipment is only part of the installed price. The estimate may include the supply fan, intake hood, filters, ductwork, heating components, control wiring, installation labor, and commissioning. Ask whether the quote includes balancing the incoming air against the exhaust hood.
| Quote component | Typical price | What changes the charge | Pricing basis |
|---|---|---|---|
| Fan and intake assembly | $500-$5,000 | Airflow, construction, sound rating | Per system |
| Ductwork and exterior hood | $500-$4,000 | Run length, size, roof or wall route | $20-$70 per linear ft installed |
| Electric or gas heat | $800-$6,000 | Heating capacity and fuel connection | Per heater |
| Controls and interlock | $200-$1,500 | Hood integration and automation | Per system |
| Labor and startup | $700-$5,000 | Crew size and installation difficulty | Project total |
Heating and duct routing are often the biggest add-ons after the fan itself. Commercial controls may also be required to coordinate system operation with the exhaust hood.
How CFM, heat output, and duct length change pricing
Airflow capacity is a major price driver. Small residential units around 200-400 CFM can cost $500-$1,500 for equipment, while 1,000-2,000 CFM commercial units may cost $2,000-$8,000 before installation. The correct size depends on exhaust volume, building pressure, and applicable code—not just the room’s square footage.
Heating adds cost, especially in cold climates. A 5-10 kW electric heater may add roughly $800-$2,500; larger electric or gas heating packages can add $2,000-$6,000 or more. Duct runs beyond about 20-30 feet, roof penetrations, and tight ceiling spaces can increase labor and materials.
Confirm the required CFM and heating load before comparing equipment prices. An undersized system may not balance exhaust, while an oversized unit can cost more to buy and operate.
How many labor hours does installation require
A simple residential installation may take 6-12 labor hours, often completed by one or two technicians. A commercial installation commonly takes 1-3 days, with more time needed for roof work, new duct routes, electrical connections, and system balancing. HVAC labor rates often run $75-$150 per hour, with commercial or specialized work sometimes higher.
For example, 12-24 labor hours at $90-$140 per hour equals $1,080-$3,360 before materials and equipment. The estimate should state whether startup, airflow testing, and cleanup are included.
Removal, electrical upgrades, and roof work can raise totals
Replacing an existing unit may cost less if the duct, wiring, and opening are reusable. Removing old equipment can add $200-$800, while a new circuit or panel work may add $500-$2,500. Roof curbs, weatherproofing, lift equipment, and difficult access can add another $500-$3,000 depending on the building.
Get separate line items for demolition, electrical changes, roof work, and balancing. This makes it easier to compare quotes and identify whether one contractor has excluded a necessary task.
Regional labor rates shift make up air system estimates
Prices in high-cost metro areas and regions with strict permitting can run about 15%-30% above a typical national estimate. Rural markets may be 5%-15% lower for labor, but travel charges or limited contractor availability can offset savings. Cold-weather locations may also need more heating capacity and insulation, while coastal sites can require corrosion-resistant equipment.
Compare local bids for the same CFM, heat type, duct scope, and controls. A lower equipment price does not necessarily mean a lower installed total if the contractor has not included delivery, access equipment, or commissioning.
Permits and inspections depend on building and system type
Residential mechanical or electrical permits may cost $50-$500, depending on the municipality and scope. Commercial permits and plan review can range from $200-$2,000 or more for larger projects. Requirements vary; a restaurant installation may need coordination with fire, mechanical, and building officials, especially when tied to a commercial exhaust hood.
Ask the contractor to identify permit fees and required inspections in writing. Code-required interlocks, make up air temperature limits, and ventilation rules can affect the design and final price.
Lower the price by controlling duct and heater scope
Keep the intake route short and accessible where the building layout allows, and compare electric, gas, and unheated options based on local climate and operating needs. Reusing sound ductwork or a suitable electrical circuit can reduce labor, but only if the components meet airflow and code requirements.
Request at least three itemized bids with matching airflow and included work. Avoid paying for oversized capacity or premium controls without a documented need, and schedule nonurgent work before peak heating or restaurant renovation seasons when contractor calendars may be tighter.
