We used the hotel's beautiful central air conditioning, and now it has started heating, but it is too hot at noon, so I want to turn it off for 2 hours. Can this save money?

As long as the phone is turned off, it will definitely save money. But you must ensure that your pipes are well insulated. If it is not good and the heat dissipation is fast, it is not necessary. After all, turning off the water pump can save electricity.

The main engine is started by temperature adjustment. If you want to save energy, lower the set temperature, but meet the national requirements for hotel temperature.

Remember to close the doors and windows in winter.

If the temperature is below zero, be sure to turn on the main engine.
