The air conditioner and heating were turned on for a long time and there was no response.

Solutions to the problem that the air conditioner and heating have not responded after being turned on for a long time: 1. The air conditioner needs to be preheated; 2. The air conditioner filter needs to be cleaned or replaced; 3. The air conditioner needs to be defrosted; 4. The air conditioner refrigerant is insufficient; 5. , Insufficient air conditioning power; 6. Incorrect air conditioning settings; 7. Air conditioning system failure. Detailed introduction: 1. The air conditioner needs to be preheated. The air conditioner needs a certain preheating time before heating in order to heat the internal cold air to the required temperature. If the preheating time is not enough, the heating effect may not be obvious. You can wait. After a period of time, see if the heating effect improves, etc.

There may be many reasons why the air conditioner and heating have not responded after being turned on for a long time. The following are some common reasons and solutions:

1. The air conditioner needs to be preheated: The air conditioner needs a certain preheating time before heating in order to heat the internal cold air to the required temperature. If the preheating time is not enough, the heating effect may not be obvious. You can wait for a while to see if the heating effect improves.

2. The air conditioning filter needs to be cleaned or replaced: If the air conditioning filter is clogged or dirty, it will affect the air circulation and thus the heating effect. The filter can be inspected and cleaned, or replaced with a new one if necessary.

3. The air conditioner needs to be defrosted: When the air conditioner is heating, if frost forms on the surface of the outdoor unit, it will affect the heat transfer and thus the heating effect. You can check whether the air conditioner needs defrosting and handle it accordingly.

4. Insufficient air conditioning refrigerant: Insufficient air conditioning refrigerant will also affect the heating effect. You can ask professionals to check whether the refrigerant is sufficient. If it is insufficient, it needs to be replenished accordingly.

5. Insufficient power of the air conditioner: If the power of the air conditioner is insufficient, the heating effect may be affected. You can check whether the power of the air conditioner matches the size of the room. If not, you may need to replace it with a more powerful air conditioner.

6. Incorrect air conditioning settings: Sometimes incorrect air conditioning settings can also affect the heating effect. You can check whether the air conditioner settings are correct and make adjustments accordingly. For example, you can check whether the temperature set value is too high or too low, and whether the mode setting is correct, etc.

7. Air conditioning system failure: If the above methods do not solve the problem, it may be that the air conditioning system itself is malfunctioning. You can ask professionals to inspect and repair the air conditioning system.

In addition to the above solutions, you can also try the following methods to solve the problem of the air conditioner heating not responding after being turned on for a long time:

1. Check the power supply and voltage: Ensure the power supply and the voltage is normal to avoid the air conditioner not working properly due to voltage instability.

2. Check the remote control battery: Make sure the remote control battery is sufficient to avoid poor signal transmission due to insufficient power and affect the normal operation of the air conditioner.

3. Check the connecting wires of the indoor and outdoor units: Ensure that the connecting wires of the indoor and outdoor units are intact to avoid problems such as poor signal transmission or power failure due to line problems.

4. Clean the radiator of indoor and outdoor units: After using the air conditioner for a long time, the radiator is prone to accumulate dust and debris, affecting the heat dissipation effect. Indoor and outdoor unit radiators can be cleaned regularly to ensure good heat dissipation.

5. Check the indoor unit filter: If the indoor unit filter is dirty and clogged, it will affect the air circulation and thus the heating effect. The filter can be checked and cleaned regularly to ensure smooth air circulation.

6. Adjust the position of the indoor unit: If the position of the indoor unit is unreasonable, such as placing it in a corner or near a window, it may affect the air circulation and heating effect. The position of the indoor unit can be adjusted to improve air circulation and heating effects.

7. Seek professional help: If none of the above methods solve the problem, it is recommended to seek professional help. Professionals can perform a complete inspection and repair of your air conditioning system to resolve heating issues.

The above are some methods and suggestions for solving the problem of air conditioning and heating not responding after being turned on for half a day. Different solutions may be applicable according to different systems and environments. Specific problems need to be analyzed in detail. If necessary, seek professional advice. help.
