Ventilation Maintenance – Scheduled Activities

The ventilation system in buildings is designed to ensure air exchange in all rooms. There are two main types of ventilation: natural, in which air is supplied and exhausted without the use of electrical devices, and mechanical, in which air exchange is accomplished by fans or ejectors, other mechanisms, and automation. The designed efficiency of all types of systems is maintained by regular ventilation maintenance.

Ventilation System Malfunctions and Their Causes
Natural ventilation is considered the least demanding in terms of maintenance. Maintenance activities consist of cleaning grilles, air ducts, and filters, which includes checking the tightness of all connections and the fastening characteristics of the components. Mechanical ventilation systems require more complex procedures. Preventive maintenance involves a thorough inspection of all components and equipment in the ventilation system. If necessary, ventilation ducts are cleaned, filters are replaced, the ventilation system is repaired, equipment is maintained, and bactericidal treatment is applied. If ventilation maintenance is coordinated according to the established schedule, the system’s risks are not cumulative: all problems are easy to identify and resolve. Air quality depends on the smooth operation of ventilation units and the sanitary condition of the air ducts. A number of symptoms can indicate that a problem has arisen: Condensation occurs due to clogged or depressurized air ducts, inefficient fan operation, or fan malfunction; a persistent odor and mold growth indicate poor performance of the supply and exhaust system. You need to perform ventilation maintenance—clean the air ducts, replace filters, and perform bactericidal treatment;
Increased ventilation noise is detected by wear on the spinning components or a faulty muffler. This problem may be caused by severely clogged ducts, freezing;
- Pulsation may occur due to loose system fasteners, weakened shock absorbers on the electric motor, or worn fan bearings;
- The greatest energy consumption, exceeding the generally accepted estimate, occurs due to equipment contamination and wear and tear.
- Ventilation Repair and Maintenance
- Depending on the condition of the ventilation system and devices, as well as the complexity of the upcoming work, repairs can be symbolically divided into three types:
- Routine repairs involve restoring the design features of the ventilation system without dismantling it. This includes cleaning the external and internal components of the system, as well as equipment that is easily accessible;

Ventilation Repair and Maintenance
Major repairs involve partial or complete dismantling of the ventilation system. If necessary, devices or individual components are sent to a workshop for diagnostics and repair. Air ducts, supply and exhaust systems are thoroughly cleaned, and electric motors are serviced.
- The main requirement is regularity in these activities. For example, the draft quality is checked annually, ducts and equipment are cleaned as needed, and a visual inspection is necessary every few months.
- Ventilation is a vital building utility system, responsible for significant functions. By paying sufficient attention to preventative maintenance, you can protect the system from major breakdowns and manage routine repairs, easily accomplished without the involvement of specialists.
