Maintenance of ventilation systems - how to properly conduct
In order for the air exchange system and the maintenance of a certain microclimate in the room to work without failures and breakdowns, periodic carrying out of a certain set of measures is required. At the same time, the maintenance of ventilation and air conditioning systems can be carried out both by qualified contractual specialists and independently.
It is important to know the main features of the workflow and not to violate the requirements of safe operation.

Types of maintenance
All activities of this group can be divided into several main types, each of which has its own characteristics:
Diagnostic measures | The simplest option, which by and large does not require a professional tool and special tools, is quite a simple set that is in every home. The main purpose of this type of work is to inspect all components and parts of the system for the strength of connections and the presence of visible damage. |
Service and maintenance | Includes maintenance of the ventilation system, aimed at maintaining a healthy state, cleaning or replacement of filter elements, as well as measurements of various indicators in order to identify failures and their timely removal, this helps prevent breakdowns |
Urgent work | The need for urgent action arises in case of failures and breakdowns in the system. Most often, in these cases, professional specialists are involved in order to restore the operability of the communications as soon as possible, except for troubleshooting, all the nodes of the system are checked to prevent its failure in the future. |

Overview of the activities carried out within the service
Consider each of the types of work in more detail, so you can understand in what cases which option will be the most rational and expedient.
Note! All the works described below are performed only on those communications for which the warranty has already passed. If the warranty period has not expired, self-intervention may lead to the termination of the warranty.
Diagnostics
If you do the work with your own hands, then you will need an instruction in which the points will list all the activities that need to be done.
The list of works may vary depending on the features of the system modification, but the most important of them are as follows:
- If the work is carried out for the first time, it is necessary to determine the type of communications, the model of the equipment used. In addition, it is important to know how long the system has worked and what resource each node is designed for. Very often, problems are caused by elementary wear and tear caused by the expiration of the parts, and only a replacement can help in solving the problem.
- The test starts with air vent filters - they must be removed and cleaned (if available) or replaced with new ones. It is the unsatisfactory condition of the filtering elements that often causes the system to deteriorate.

- Next, carefully check all the grilles for ventilation - both the air distribution inside the premises and the air intake outside. If necessary, they can be washed or cleaned.
- Electrical circuits are also checked for health and integrity. All wires must be without visible damage, connections must be reliable, where necessary, they must be protected from moisture.
- As part of diagnostics, the difference in temperature and air pressure outside and inside the building is measured; these figures are compared with the values presented in the technical documentation. Values must be within the limits established by the manufacturer of the equipment or design organization.
Note! Do not forget to check the emergency shutdown system ventilation in case of emergency situations and failures. This will protect communications from overload.

Periodic service
Maintenance of ventilation systems includes the following work:
- Measurement with the help of special devices of voltage in all parts of the circuit, it should not differ, any deviations indicate problems that need to be fixed immediately.
- Cleaning of all elements, except the grilles and filters, should check the condition of the fans and air ducts. They are also susceptible to clogging, especially if the building is located in a city where the air is fairly dirty, and if it enters the system on all surfaces, a raid forms.

- Maintenance of the ventilation and air conditioning system also includes the analysis of the temperature of individual units and areas. As a rule, in places where there is a problem, this figure is much higher.
Emergency service
This option is relevant when the maintenance of the ventilation system is carried out unplanned as a result of a breakdown. Most often, it is carried out by professional experts, since the malfunction must be eliminated as quickly as possible in order to restore ventilation.
The price of this type of work may vary and depends on the nature of the malfunction and the cost of spare parts necessary to restore the system to work.

Conclusion
Self-service most often consists in cleaning the elements, visually inspecting the assemblies and making control measurements. More difficult cases are better to entrust to professionals.
