Ventilation focuses on exchanging indoor air with fresh outdoor air to maintain air quality, while air conditioning controls temperature and humidity. Both are essential components of a complete HVAC system.

Commercial kitchen ducts should be cleaned every 3-6 months, while general ventilation ducts need cleaning annually. Clean rooms require more frequent maintenance based on usage and contamination levels.

Clean room installation requires HEPA/ULPA filtration, positive pressure control, sealed construction, environmental monitoring systems, and compliance with ISO 14644 standards for the specific cleanliness class required.

Yes, existing buildings can be retrofitted with fresh air systems. We conduct site surveys to design optimal solutions that integrate with existing HVAC infrastructure while minimizing structural modifications.

Air curtains create an invisible barrier that prevents conditioned air from escaping through open doors, reducing HVAC load by up to 80%. They maintain indoor temperature while allowing free access, especially beneficial for retail stores and cold storage facilities.
