Why is the cooling effect of hot air conditioning poor in weather?

There are many reasons, such as the following:

1. Insufficient refrigerant in the system.

2. The system is a little blocked.

3. The internal fan network is blocked.

4. The external machine has poor heat dissipation effect.

6. The temperature control circuit is faulty.

7. The internal fan speed is too slow.

8. The room is too large or the thermal insulation performance is poor.

9. Too much refrigerant.

10, air conditioning installation exhaust volume is not enough.

In addition, unstable or too low power supply voltage can also cause this phenomenon. It is best to find a knowledgeable master to check some, find out the cause of the failure and eliminate it.
