As you conclude a day of travel and long for the comfort of a warm or cool room back at the hotel, only to find...A "strike," no doubt, would severely impact rest and mood.

How to Simply Judge If the Hotel Air Conditioning Is Not Heating

1. Set issues/preheat

Remote control mode not set"Set to 'Heating,' or if the unit is just turned on, blowing cold or natural air for an extended period. Switch to 'Heating' mode, set the temperature above 25°C, and wait patiently for 10-15 minutes."

2. Filter/Exhaust Vent Clogging

The air outlet has low airflow, making the warm breeze feel weak. Inspected and adjusted the outlet blades to ensure they were not obstructed.

Outdoor temperatures too low/defrosting in progress

Outdoor unit frosting, indoor unit pauses hot air supply (with potential indicator light blinking). This is a normal defrosting process, typically lastingPlease wait for 5-15 minutes.

Outdoor unit heat dissipation受阻

Outdoor units are covered in snow and ice, debris, or installed in overly confined spaces. If convenient and safe to do so, observe if there are any obvious blockages around the outdoor unit.

5. Insufficient refrigerant (Freon) supply

Similar to not cooling, the heating effect is significantly reduced. Requires professional maintenance. Inform the repair technician of this possibility.

6. Heating Core Component Failure

A four-way valve malfunction (causing failure to switch to heating mode), or compressor or capacitor failure. Requires professional repair. If cooling is normal during summer but heating fails during winter, a four-way valve malfunction is likely.

Special Reminder: Winter Heating Alert

Preheating and defrosting are normal: The slow start-up for heating in winter and periodic blowing of cold air for defrosting during operation are due to the working principle of heat pump air conditioners, not a fault.

Watch Out for Outdoor Temperatures: Most Standard Air Conditioners Fail BelowAt temperatures ranging from -5℃ to -7℃, the heating efficiency will significantly decrease, and it may even be difficult to operate. If the local temperature is extremely low, it may be due to objective conditions.

Adjust the Airflow: Since warm air is lighter, it's recommended to tilt the outlet blades downward to promote circulation of the warmth towards the lower part of the room, resulting in a more comfortable feeling.
