Fraser Valley's
COMMERCIAL MAKE-UP AIR SYSTEMS CONTRACTOR
Breathe Better. Balance Airflow. Built to Code.
In well-sealed commercial buildings, ventilation alone isn't enough.
As air is exhausted from kitchens, restrooms, or equipment rooms, it needs to be replaced—or made up—with fresh, tempered air. That's where Alpine's make-up air systems come in.
We design, install, and maintain high-performance make-up air (MUA) systems that restore balanced air pressure, improve indoor air quality, and meet evolving building code requirements.

$2M+ in Ready Inventory
= Less Waiting for Parts
Alpine maintains over $2 million in ready-to-deploy inventory, including components for make-up air systems—ensuring faster service and shorter project timelines.
From gas valves and control boards to blowers, sensors, and burner assemblies, we stock the essentials to build or repair most systems without waiting on suppliers. This keeps your project on schedule and your building code-compliant.
Our long-standing supplier network also gives us priority access to specialty parts for both older systems and the latest high-efficiency models—reducing lead times and preventing delays on inspections or occupancy approvals.
24/7/365
2-Hour Emergency Response Time
When a make-up air system fails—whether from a burner issue, motor failure, or control board malfunction—the building quickly suffers from negative pressure, poor air quality, and increased safety risks.
For enclosed spaces like underground parkades, warehouses, or multi-tenant facilities, this isn't just inconvenient—it's a code violation waiting to happen.
That's why Alpine offers 24/7 emergency response across the Fraser Valley. Our on-call technicians are directly dispatched—no call centers or answering services—so we arrive fast with fully stocked vehicles ready to get airflow restored. From diagnosing faulty sensors to swapping out failed gas valves, our experienced team knows how to restore balance and bring your building back into compliance quickly.
When building pressure fails, code violations follow. That's why Alpine is the first call when ventilation failure isn't an option.

A make-up air system replaces air that has been exhausted from a building through ventilation, kitchen hoods, or industrial processes. It prevents negative pressure, improves indoor air quality, and maintains comfortable temperatures.
Modern buildings are well-sealed for energy efficiency. When exhaust systems remove air without replacement, the building depressurizes, causing doors to stick, drafts, uncomfortable conditions, and inefficient HVAC operation. Make-up air systems solve these issues.
We install all types of make-up air units including direct-fired, indirect-fired, and electric units. Heating options include gas, steam, hot water, and electric resistance. Cooling options include evaporative cooling, DX coils, and chilled water coils.
Commercial kitchens, industrial facilities, warehouses, parking garages, laboratories, manufacturing plants, and any building with significant exhaust ventilation typically require make-up air systems.
Make-up air units can be installed on rooftops, through walls, on ground pads, or vertically outdoors. We design the installation based on your building's layout, space constraints, and operational requirements.
We perform detailed load calculations considering exhaust CFM, building size, climate conditions, heating/cooling requirements, and code requirements. Proper sizing ensures optimal performance and energy efficiency.
Modern make-up air systems are designed for high efficiency. We offer units with energy recovery, variable speed drives, and advanced controls that significantly reduce operating costs compared to older systems.
