Restaurant HVAC Installation

Restaurants operate under demanding conditions that standard HVAC approaches cannot adequately address. Commercial kitchens generate substantial heat, grease-laden vapors, smoke, and odors that must be captured and exhausted effectively. Dining areas require comfortable temperatures despite their proximity to hot kitchens. The entire system must balance properly to maintain air quality without creating pressure problems that affect door operation or allow kitchen odors into dining spaces.

We specialize in the complete ventilation and HVAC installation requirements of restaurant operations, from small cafes to large full-service establishments. Our work addresses both the technical requirements of proper kitchen ventilation and the practical realities of restaurant operations where downtime directly affects revenue.

Understanding Restaurant Ventilation

Commercial kitchen ventilation functions as an integrated system rather than a collection of separate components. The exhaust hood positioned over cooking equipment captures heat, smoke, grease particles, and combustion products. Ductwork carries these contaminants to the rooftop exhaust fan, which expels them above the building. The makeup air unit replaces exhausted air with conditioned outdoor air, maintaining proper building pressure and providing fresh air for combustion and occupant comfort.

When any component is undersized, improperly installed, or poorly coordinated with the others, the system fails to perform adequately. Kitchens become oppressively hot. Smoke and odors escape into dining areas. Grease accumulates in ductwork creating fire hazards. Negative pressure makes doors difficult to open and pulls unconditioned air through any available gap. Code inspections fail and violations follow.

Proper installation establishes the foundation for a ventilation system that performs reliably for years. While ongoing maintenance including hood cleaning and filter replacement remains necessary, well-installed systems require only routine care rather than constant troubleshooting.

Kitchen Exhaust System Installation

Kitchen exhaust installations begin with properly sized and positioned exhaust hoods. Hood type, size, and mounting height depend on the cooking equipment below and the volume of effluent that equipment generates. Type I hoods serve grease-producing cooking equipment while Type II hoods serve heat-only appliances like dishwashers and ovens.

Ductwork connecting hoods to rooftop fans must meet specific code requirements for commercial kitchen applications. This typically means listed grease duct meeting UL 1978 or equivalent standards, properly supported and sealed, with appropriate fire dampers and access panels for cleaning. Duct routing affects system performance and must be designed to minimize length and turns while meeting clearance requirements.

Rooftop exhaust fans provide the motive force for the system. Fan sizing must match hood requirements while accounting for duct losses. Fans must be positioned to discharge above the roof line and away from air intakes, and the installation must include proper curbs, flashing, and weatherproofing.

Makeup Air Installation

Makeup air systems replace the air exhausted from the kitchen, maintaining building pressure balance and providing fresh air for combustion and ventilation. Without adequate makeup air, exhaust systems cannot perform effectively, and negative pressure creates numerous operational problems.

Makeup air units condition incoming air by heating it in winter and sometimes cooling it in summer. This conditioning prevents the discomfort of raw outdoor air entering the kitchen and dining areas. Unit sizing must match exhaust volume while accounting for any other exhaust in the building.

Integration between makeup air and exhaust systems ensures they operate together appropriately. When the exhaust system runs, the makeup air system should operate correspondingly. Improper integration leads to pressure imbalances and comfort problems.

Dining Area HVAC

Beyond kitchen ventilation, restaurants need climate control for dining areas, waiting spaces, restrooms, and back-of-house areas. Rooftop units typically provide this heating and cooling, sized to maintain comfortable conditions despite the heat load from the kitchen and the variable occupancy of dining spaces.

Proper zoning allows different areas to maintain appropriate temperatures. Dining rooms may need cooling while back-of-house areas need heating, particularly during shoulder seasons. Multi-zone rooftop units or multiple smaller units can address these varying requirements.

Frequently Asked Questions

What does a complete restaurant ventilation installation include?

A complete installation includes exhaust hoods over cooking equipment, grease-rated ductwork to the roof, rooftop exhaust fans, makeup air units with appropriate conditioning, and all necessary controls and connections. We also handle permit applications and coordinate required inspections.

How long does restaurant ventilation installation take?

Timeline depends on project scope and building conditions. A straightforward installation in a shell space with good rooftop access might take several days. Complex installations with difficult duct routing or occupied building constraints may require longer. We provide project timelines during the quote process.

Can you install ventilation during restaurant operating hours?

We schedule work to minimize impact on restaurant operations, which typically means working during closed hours for occupied restaurants. Some work, particularly rooftop equipment installation, may be possible during operating hours with minimal disruption. We discuss scheduling options for each project.

What ongoing maintenance does restaurant ventilation require?

Properly installed systems require regular hood cleaning by certified cleaning contractors, filter maintenance, and periodic inspection of fans and ductwork. Quebec regulations specify cleaning frequencies based on cooking volume. We install systems with proper access for maintenance.

Do you work on restaurant renovations or only new construction?

We handle both new construction and renovation projects. Renovations often involve working within existing building constraints and may require creative solutions for duct routing and equipment placement. We assess existing conditions and develop approaches that work within available space.

How do I know if my restaurant’s ventilation needs replacement or just repairs?

Systems that consistently fail to control kitchen heat and odors, that have failed inspections, or that create persistent comfort problems often need more than repairs. Age, condition of ductwork, and whether the system was properly designed originally all factor into this assessment. We can evaluate your existing system and provide recommendations.
