Tips Before Installing a Ventilation System

Accurate airflow calculation: Before designing the system, it is essential to calculate the air exchange rate based on the purpose of the space. In a residential apartment, the air should be fully refreshed at least once per hour, while in commercial spaces (e.g., gyms, cafes), it should be refreshed 4 to 8 times per hour, depending on the foot traffic. Balance between intake and exhaust: Relying solely on exhaust ventilation (extractors) is a mistake. If there is no fresh air intake into the room, negative pressure (a vacuum) is created, which leads to doors becoming difficult to open, headaches, and unpleasant odors being pulled in from bathrooms. Correct selection of ductwork (routing): To reduce noise in residential areas, use specialized sound-insulated or flexible insulated ducting (hoses). Avoid sharp, 90-degree bends — every sharp angle increases system resistance, generates noise, and cuts down operating efficiency. Energy savings with a heat recovery ventilator (HRV): To prevent ventilation from increasing your heating and cooling bills in winter or summer, install a heat recovery system. It warms or cools incoming fresh outdoor air using the energy of the outgoing (warm/cool) exhaust air, saving up to 80% on energy. Accessibility for filters: Any ventilation unit and air duct fills with dust over time. Carefully incorporate access hatches during installation so that future filter replacements, fan servicing, or duct cleaning can be carried out easily without breaking the ceiling. 💡 Breathe clean air: Find certified ventilation engineers, air duct installers, and leading specialists in ventilation systems on the platform: services.ss.ge
