How often the air conditioner should be serviced: list of works and peculiarities

Although there are general recommendations to service an air conditioner twice a year, how often it is needed depends on the operating conditions. If the equipment is used only in summer and not every day, there is no need to check the condition of all parts and to carry out general cleaning so often. But when the conditioner works daily in the cold season for heating and in summer for cooling, service maintenance may be needed more often than twice a year. Let's consider, what works on maintenance of conditioners are carried out, their peculiarities. This will help to determine how often to service the climatic equipment.

List of works on air conditioner maintenance

Service maintenance of split-systems includes:

• Cleaning and disinfection of the internal and external unit of the air conditioner, filters.
• Checking the tightness of drainage and freon pipelines.
• Refilling of refrigerant.
• Checking the operation of the electronic control panel.
• Testing the response of the air conditioner to commands from the remote control.

Let's take a closer look at these air conditioner maintenance activities. They have peculiarities that are important to consider.

Cleaning of air conditioner units

Such elements of the air conditioner are cleaned:

• The evaporator and the impeller of the indoor unit are treated with a steam generator.
• The tray and drainage are washed with antiseptic agent, accumulations of deposits, mold fungi are removed.
• The outdoor unit is cleaned of dust and debris.

Check the condition of the air conditioner pipes

Freon in the cooling system is lost by several percent per year. This affects the pressure level in the pipes. If the Freon leakage is more than normal, the required amount of refrigerant is pumped into the system.

It is important to entrust Freon charging only to professionals. There is a risk of adding too much of it. If there is an excess of freon, the compressor can break.

When the air conditioner is dirty, the movement and escape of moisture from condensation can be impeded. This creates a favorable environment for mold growth. Also, the equipment uses more energy to heat or cool. Overloading leads to rapid wear of parts and breakdown. Therefore, it is necessary to service the air conditioner in time.

Checking the control panel of the air conditioner

The air conditioner is tested in different operating modes. Check whether the actual temperature of the air coming out of it corresponds to the one specified in the program. They determine whether the electronic system does not hang up, how quickly it reacts to pressing buttons on the panel or through the remote control.

Checking of parts of air conditioner mechanisms

The operability of the system depends on the quality of connections and nodes. Check such elements of the air conditioner:

• Whether the threads of hoses and joints of other elements are tightly screwed.
• Whether contacts of electrical connections are securely fixed.
• Whether the equipment consumes electric current according to the same parameters as stated in the passport.
• Whether the bearings of the air conditioner fan motor are not worn out.

A sign that there are malfunctions in the air conditioner parts - extraneous noises during operation, whistling. A repair specialist can determine exactly what the problem is and how to eliminate the malfunction.
