Commercial Fan Services

Unlike regular fans, which create a breeze by pushing air forward, exhaust fans work by sucking air outdoors, or in some cases, into an air purifying/filtering system that re-directs clean air back into the room or building. Other than kitchen exhaust fans, which are typically found over ranges and other cooking appliances, most exhaust fans are installed in or near the ceiling or attached to ducts that vent outside. Commercial exhaust fans are important to the safe and efficient use of commercial properties, from warehouses to restaurant kitchens. Call us for professional exhaust fan service.

An attic exhaust fan is a fan that’s installed in or near the attic’s ceiling or in the rafters of a home or commercial building to vent air outside. Since heat naturally rises, an attic exhaust fan keeps hot air and moisture from being trapped inside.

If you notice one or more of the following, it may be time to schedule an industrial exhaust fan service visit:

• Unfamiliar noises that you haven’t noticed before (grinding, metal-scraping sounds, loud buzz or hum).
• Unusual blade rotation (blades moving slower than normal or unusually fast).
• Excessive vibrating or shaking.
• Signs of overheating (visible smoke or a “hot” smell emitting from the unit).

The Occupational Safety and Health Act of 1970 requires that businesses provide employees with a safe workplace, which includes protecting them from potentially harmful airborne particles. OSHA does not specify indoor air quality regulations, but there are mandates regarding acceptable levels of specific airborne contaminants within the workplace.

Commercial kitchen exhaust fans are often required in restaurants and other businesses that operate commercial kitchens, like schools and hospitals. Additionally, industrial exhaust fans are required in certain manufacturing businesses and other locations where air quality may be compromised. Check with state and local authorities regarding exhaust fan requirements in your area.

Even if your business operations don’t generate hazardous chemicals or excessive dust, you may consider installing exhaust fans to remove unpleasant odors, circulate air, and improve indoor air quality.

For example, common items like fabrics, floor coverings, cleaning supplies, air fresheners, adhesives, and all sorts of other culprits may emit volatile organic compounds (VOCs) into the air. VOCs are chemical airborne contaminants that may cause headaches, fatigue, nausea, and even respiratory distress in sensitive individuals. An exhaust fan will expel stale, contaminated air and bring fresh air into the building.

Although whole-house or attic exhaust fans typically help lower indoor temperatures because they draw a considerable volume of hot air up and out, small exhaust fans by themselves aren’t likely to have a significant cooling effect. They may help rooms feel slightly cooler by keeping air circulating, but they don’t lower the air temperature the way an air conditioner does.

Exhaust fans are important to the safety of your business. Depending on the facility, they may need to be capable of expelling chemical vapors, fumes, smoke, dust, and other fine particles that can irritate the eyes, skin, or respiratory systems of the people inside the building. In some buildings, industrial fans are used to force air into spaces with limited ventilation (e.g., underground workspaces.)

You can make sure that all commercial exhaust fans are well-maintained and in good working order by scheduling regular maintenance appointments. Industrial exhaust fan maintenance routines vary depending on size, model, and usage patterns. Some fans will need to be serviced monthly, while others can be inspected quarterly or annually. Commercial systems are complex, so most (if not all) commercial exhaust fan repairs should be completed by a professional.
