Breathe better. Balance airflow. Built to code.

Commercial make-up air contractor since 1969.

In commercial kitchens, industrial shops, paint booths, grow ops, and warehouses, exhaust without tempered make-up air starves the building. Negative pressure pulls combustion gases back down flues, slams doors, kills hood capture, and frustrates everyone working inside. For 56 years, Fraser Valley operators have trusted Alpine to design, install, and maintain the make-up air systems that keep their buildings balanced.

Whether you're feeding a Chilliwack hood line, a multi-bay industrial paint booth in Abbotsford, or a cultivation room that needs tight air-change and temperature control, we engineer for the load, the code, and the comfort of the people in the room.

24/7/365 response

2-hour average emergency response

When the MAU goes down on a Friday night dinner rush, the kitchen has to shut. Alpine guarantees a 2-hour average emergency response time throughout the Fraser Valley, 24 hours a day, 365 days a year. Our emergency line connects directly to on-call technicians - no answering services, no triage delay.

Emergency repair & service

When exhaust runs but make-up air doesn't, downtime isn't an option.

Make-up air failures stop kitchens, paint booths, and grow rooms cold - and they cascade fast into hood capture failures, depressurized buildings, and gas appliances spilling combustion products. Alpine's 24/7 emergency response team arrives fast with fully-stocked service vehicles. Our experienced technicians diagnose and repair all commercial make-up air brands and configurations.

Custom make-up air system design & installation

Every building moves air differently. Alpine's design team works with you to spec a make-up air system that matches exhaust loads, holds the building near neutral pressure, tempers the air to a setpoint occupants can live with, and meets current gas, ventilation, and building-code standards. From a single direct-fired packaged unit to a multi-zone DOAS with energy recovery, we engineer for serviceability over the life of the equipment.

From a single hood to a multi-zone DOAS

Our technicians have experience designing and installing complex ventilation systems for commercial clients.

From a single direct-fired make-up air unit feeding a restaurant hood to a multi-zone packaged DOAS with energy recovery and demand-controlled ventilation, we approach every project the same way: size to the exhaust load, balance the building, and leave it commissioned with documentation that satisfies the inspector.

By choosing Alpine, you're not just hiring another contractor - you're hiring our 56-year reputation for reliability, technical service capability, and decades of combustion and airflow know-how built right here in Chilliwack.

Our team is a tight-knit, three-generation crew that treats your building like its own. Some of our staff have been with Alpine for the better part of 30 years; we keep training, certifications, and balancing instruments sharp so we leave every job dialled-in and provably better.

In addition to supporting businesses across the Fraser Valley, we work with hospitality groups, industrial plants, grow operations, and institutional clients across BC's Lower Mainland - and we're ready to travel for more remote or custom projects.

Chilliwack, BC · Since 1969

The mountain on our wall.
The standard in our work.

Freshly painted across our Chilliwack shop, the mural is a new Fraser Valley landmark, and a fitting one. Local artist Jack Hendsbee brought the mountain to life, and it will feature in the Chilliwack Mural Festival. The peak has been our namesake since 1969, and it is the standard we bring to every install, service call, and 2 AM emergency. We back the local community the way it has backed us.
