When is a ventilation system repair required?

Broken ventilation in a residential building or office leads to many difficulties. Because of this, health is worsening, ailments arise. But when the equipment does not work within the industrial facility, more serious consequences are likely. Many processes are associated with the formation of vapors, toxic components, and dust that need to be neutralized. Repair of the ventilation system can eliminate the shortcomings.

Causes of System Failure

The ventilation system is considered one of the most important. It should be in each building, taking into account the purpose. The easiest to maintain is considered the natural ventilation of residential buildings. In industrial facilities there are mechanical supply and exhaust systems.

The equipment fails for the following reasons:

• violation of installation;
• misuse;
• wear of mechanisms;
• failure to perform maintenance;
• mechanical effects.

The type of malfunction depends on the operating conditions of the system. For example, the supply and exhaust systems located near busy highways quickly become clogged. Natural ventilation of the houses also requires repair and cleaning. Often people partially install ventilation ducts, because of which there is a violation of air movement. In this case, repair of the ventilation system is required.

Signs of a malfunction

Repair and maintenance of ventilation systems is required when:

• fogging of windows;
• mold in the corners;
• the flow of odors from one room to another.

Repair work is also required because of difficulty breathing people, asthmatic phenomena. In such a room, a person often catches a cold, there are pains in the back, joints.

Repair Steps

Repair of the ventilation system involves the following steps:

1. Diagnostics and removal of defects in the operation of the equipment is performed.
2. Prevention, which is required for the normal functioning of systems. It includes cleaning, troubleshooting, testing.

Operational maintenance involves debugging and prevention of mechanisms that ensure the smooth operation of ventilation. This work is required regularly. Repair and maintenance is carried out in stages. First, the master examines the condition of the equipment, and then he performs cleaning and disinfection. At the end, the quality of the repair is determined and a document is provided.

Typically, ventilation system repairs are carried out without dismantling. But in difficult cases, the equipment is removed, transported to the workshop, and then installed. During this work, the following services are carried out:

• connections of channels, fixtures, integrity are checked;
• mechanical parts are lubricated, filters are cleaned;
• automated control systems are tested;
• inspected electrical wiring;
• the operation of the dampers is checked;
• fans are cleaned;
• heaters and heat exchangers are being repaired;
• the heat exchanger is checked;
• defective parts are replaced.

Supply and exhaust systems use heaters to heat the air to the desired temperature level. This device can be water, fire or steam. Some use glycol solutions. Washing the heater is considered an important way to repair it. The device is disassembled, cleaned of germs and scale by chemical means. Often a heater replacement is required.

How often should the ventilation and air conditioning systems be repaired? It all depends on the type of ventilation, the specifics of the building. Usually, craftsmen call at the first sign of failure. And prevention will prevent many unpleasant consequences of breakdowns.

Diagnostics

Before the overhaul of the ventilation, the following diagnostics are performed:

1. The system view is set.
2. Assessed condition.
3. The difference in pressure and temperature in the building and on the street is determined.
4. The air speed in the ventilation is set.
5. An assessment of the state of the gratings is carried out.
6. There is a check of the functioning of automatic systems.
7. The condition of the fans is examined.
8. The operation of the emergency shutdown is evaluated.

Diagnostics requires special devices. The event is mandatory before operation, before repair and during maintenance. Based on the information received, conclusions are made about the malfunction.

Automation Service

During the construction of modern houses, supply and exhaust systems with automatic control are increasingly being used. The user sets the necessary parameters or sets the operating mode.

System configuration should only be performed by the wizard. Adjustment of automation is included in the list of services for maintenance and repair of ventilation. As a result, the room will have normal temperature, humidity and air velocity.

The cost of repair and installation of the ventilation system is set by the estimate. The list of services that companies offer is different. The price depends on the type, capacity, branching network, quantity and type of equipment. If you plan to carry out repairs or maintenance of ventilation, you should familiarize yourself with the offers of several companies, pay special attention to the qualifications of the master, equipment with equipment, tools.
