What is the reason why the air conditioner doesn't heat in cold weather?

The reason why the air conditioner does not heat may be that the filter screen is dusty, the refrigerant is insufficient, or the wind wheel is out of order.

1, the filter screen is dusty.

After the hot summer, winter hasn't come yet. During this period, the use times of air conditioners are numbered. The air conditioner has been used for a long time, and a lot of dust and bacteria will accumulate inside. The function of the filter screen is to absorb the dust in the air. If there is too much dust, but it is not cleaned in time, it will affect the air circulation, resulting in a decrease in the air volume at the air outlet, which directly leads to insufficient heating capacity.

2. Insufficient refrigerant

The air conditioner can't heat under the condition of insufficient refrigerant. If you can't heat it, you won't blow hot air. At this time, it is necessary to invite professional maintenance personnel to add refrigerant. Adding refrigerant is a technical job. Don't refer to the online method to add it yourself. It is very dangerous to operate blindly without technical support.

3, the wind wheel failure

If the above reasons are not true, but the air conditioner just can't produce hot air, then there is a final possibility that the air conditioner rotor is out of order. You can remove the air conditioning panel after the air conditioner is powered off, find the fan wheel under the air supply outlet, and turn it by hand to see if you can easily turn the wind wheel.

Matters needing attention in air conditioning heating

1, the air conditioning temperature setting should be appropriate: many people always think that the higher the air conditioning temperature in winter, the warmer it will be. In fact, it is best to set the air conditioning temperature between 20℃ and 24℃ in winter, and 20℃ is the best. This temperature can avoid air conditioning overload and increase power consumption.

2. The filter screen should be cleaned regularly: when using the air conditioner in winter, the filter screen inside the air conditioner should be cleaned on time. The filter can be directly washed with tap water, dried and then put back. Cleaning the filter regularly can effectively reduce power consumption and avoid odor.

3. Increase indoor humidity: turning on the air conditioner for heating will dry the indoor air. In order to ensure indoor humidity, humidifier can adjust indoor humidity. In addition to the humidifier, you can also place a basin of water indoors or wipe the floor regularly, which can also have a good humidification effect. In addition, it is also good to raise more green plants.

4. Warm air blowing down: when air conditioning is heating, let the hot air from the air outlet blow down, so that the blown hot air will naturally rise, thus filling the room with warmth, greatly improving the heating efficiency, saving energy and reducing consumption.
