Winter is approaching, and the temperature is decreasing day by day. According to the weather forecast, the cold air has come again recently, and the temperature has continued to drop to -10°C. In order to prevent freezing and the air conditioner is malfunctioning, hurry up and repair it and need to add refrigerant. The citizens quickly added it.
For many citizens, the air conditioners in their homes are old-fashioned air conditioners, which have been used for a long time and are rarely overhauled, so that the cooling effect is reduced. Did not care too much. In fact, old-fashioned air conditioners generally use R22 refrigerant. Long-term use will lead to insufficient refrigerant. If the cooling effect is not good, it is good to add some R22 refrigerant to a regular air-conditioning center.
Of course, other reasons are not excluded. The reasons may also be the following:
1, the power supply is unstable
2, there is too much dust inside the air conditioner, and it has not been cleaned in time
3, the power of the air conditioner Not enough to cause no cooling
4, the outside temperature is too high
5, the copper pipe connecting the indoor unit and the outdoor unit air conditioner is too long
But in general, The possibility of lack of refrigerant is very high, so the heating effect of the air conditioner is not good, just add some refrigerant. In fact, it is very easy to add refrigerant, and people who have experience in repairing air conditioners can basically do it. If you really don’t, just find a repairer to add it.
