Warehouse & Industrial HVAC in Surrey

Industrial HVAC, unit heaters, make-up air, and exhaust fans for Surrey warehouses, distribution centres, and manufacturing facilities. We size every system to your ceiling height, door cycle frequency, and target temperature.

Warehouse HVAC is about physics: high ceilings trap heat, large doors dump cold air in, and the occupancy load can swing from empty to 50 workers in the same shift. Get the sizing wrong and you're either burning gas all day trying to heat unconditioned air, or employees are layered up in parkas. We do the heat-loss calculation first, then spec the equipment.

What We Handle

Unit heater sizing, supply, and installation (gas-fired, hot-water, or electric)
Make-up air unit (MUA) design for buildings with loading docks or high air exchange
Industrial exhaust fan installation and CFM balancing
Destratification fan installation to recover heat from ceiling peaks
Radiant tube heater installation for spot heating in loading docks
Evaporative pre-cooling for summer comfort in non-conditioned warehouses
Dust and fume exhaust system design for light manufacturing
Energy management controls and time-scheduling for occupied vs. unoccupied hours

Signs You Need Us Now

These are the warning signs our technicians see most often in the field. If any of these sound familiar, don't wait for the full failure.

Ceiling temperature is 15°C+ warmer than floor temperature (stratification)
Unit heaters struggle to maintain setpoint when bay doors open
Workers in one section of the warehouse are always cold, others are fine
Condensation forming on the roof deck or steel structure
Energy bills peak in January but the temperature never feels consistent
Exhaust fans are not clearing fumes, dust, or humidity effectively

Equipment & Brands We Work With

We supply and install Reznor, Modine, and Cambridge unit heaters. For make-up air, we use direct-fired units from Nortek and Cambridge. Destratification fans come from Big Ass Fans and MacroAir. We use Greenheck and Cook for industrial exhaust. Equipment is always matched to the actual heat-loss calculation, not rule-of-thumb guesses.

How We Work

We walk the space before quoting, measure the building envelope, check insulation R-values, count door openings, and note any process heat sources. The written quote includes the load calculation so you can see the math. Installation is scheduled around your receiving and shipping schedule to minimise disruption.

Surrey Commercial HVAC Services doesn't sub out to random crews. Our own licensed technicians handle every step. When the job is done, you get a complete handover package: equipment manuals, warranty registration, service records, and a direct line to your account technician.

Common Questions

How many unit heaters does my warehouse need?

It depends on ceiling height, insulation, door frequency, and target temperature. We do a proper heat loss calculation before sizing any equipment. Undersized heaters cost more to run long-term.

What's the difference between a unit heater and an industrial furnace?

Unit heaters are direct gas-fired or hot-water coil units suspended from the structure. Furnaces are centralized with a duct distribution system. Warehouses over 20,000 sq ft often use a combination.

Do you handle destratification fans?

Yes. Slow-moving ceiling fans push warm air from the peak back to floor level, which can reduce heating costs 20–30% in high-bay warehouses. We supply and install them as part of a complete ventilation package.

Do I need a permit for warehouse unit heaters?

Yes, gas-fired equipment requires a BC Safety Authority (BCSA) gas permit. We pull all permits and arrange the inspection as part of our standard installation process.
