How to turn on the air conditioning after winter

The life span of an air conditioner is largely dependent on proper operation and quality care. As a result of inconsistent and hasty actions, this device can completely fail. Therefore, to ensure that your climate equipment runs smoothly throughout the hot season, you need to know how to properly carry out its first launch after winter.

Preventative measures

Please note that the failure of the air conditioner due to improper technical prevention or lack thereof will not be recognized as a warranty case. Therefore, repair or complete replacement of equipment will completely rest on the shoulders of its owner. To avoid such unpleasant lessons, you should familiarize yourself with a few simple rules, the implementation of which will guarantee the effective and smooth operation of the equipment.

So, how do you turn on the air conditioner after a long period of inactivity? In fact, there are some simple rules, the implementation of which is mandatory for each owner of the climate equipment.

Temperature mode

Instructions for use of the device always indicate at what temperature it is allowed to turn on the air conditioner. As a rule, these indicators range from 0 to -5 ˚C. Thus, the device should not be turned on until the air warms up to the required temperature. In addition, at low temperatures, turning on the air conditioner is not particularly necessary.

System cleaning

The air conditioner consists of indoor and outdoor units, each of which needs regular cleaning, and especially before starting.

Filters and internal parts must be cleaned at least once a month. And after a long winter downtime, this procedure should be performed especially carefully: the indoor unit is rinsed with water, and it is best to use a compressor with compressed air to clean the outside. If you ignore these recommendations, the technique may fail. People who are in the room where the uncleaned appliance is operating will breathe dust and dirt that spreads indoors during the first use.

Before turning on the air conditioner, you should inspect the fan blades and the grill to prevent them from getting leaves, poplar fluff, twigs, and other foreign objects. If you find that the grate needs to be cleaned, you can call a specialist or clean it yourself. To do this, the device must be disconnected from the power supply so that the moving fan blades do not injure your hands.

Electrical contacts

The obligatory action before starting is to check the electrical contacts and electronic components of the device. If malfunctions are found, it is best to call specialists who have special equipment to check the functionality of the compressor and other details.

System pressure and freon refueling

Checking the pressure in the system and refueling with freon are also necessary before starting the air conditioner. The main source that supports its performance is freon. The flow of freon can lead to damage to the equipment. However, one should also remember the so-called standardized leakage, which is considered an inevitable phenomenon caused by the peculiarities of the connection of the internal and external blocks. Freon is not dangerous for a person indoors, but if it is not enough in the air conditioning system, the device can work with significant interruptions.

Checking Outlet Temperature

After checking the air conditioner and cleaning it, check which air exits the ventilation grill.Normally, it should be cold. To determine the degree of air coldness, subtract the temperature of the air entering the device from the temperature of the air that leaves. This value is called the temperature delta T. The normal value for it is a temperature of -11 to -6 C˚. In the case when the temperature of the air supplied is below -11 C˚, the air conditioner will not be able to cool the air efficiently in very hot weather. If the temperature is above -6 C˚, then the operation of the system may be disrupted.

Turn on the air conditioner

After the winter, with the onset of the first warm days, you can begin to start the air conditioner. To do this, follow these steps:

• make sure that the outdoor temperature is not lower than 0 C˚;
• disconnect the air conditioner from the network;
• to carry out all necessary actions to clean the equipment;
• check battery operation in the remote control; replace if necessary;
• connect the device to the network;
• make sure that the room temperature is at least 20 C˚, select the cooling mode on the remote control, turn on the air conditioner and set the minimum temperature (18 C˚). The fan speed should be maximum;
• wait for a while when the air goes cold air, leave it to work in this mode for 10-15 minutes. Then you should try the fan at different speeds, the shutter. If the device responds well to all manipulations (blowing weaker or stronger, moves the curtain), then this means that the device is serviceable and ready for the summer season.

In what cases is it necessary to consult a specialist?

1. If the radiator of the outdoor unit is very dirty.
2. If the outdoor unit is damaged (for example, it has a broken case).
3. If, when set to cooling mode, the air conditioner does not blow cold air 10 minutes after starting it.
4. If the air goes not cold enough.
5. When abnormal noise occurs in the device.
6. In the event of any incomprehensible situations (there is no reaction to the remote control, the lights are blinking or the air conditioner generally refuses to work).

Air conditioning requires care and attention from its owner. The implementation of the above rules and recommendations will extend the life of your device and ensure its effective operation for many years.
