How to Use Your Air Conditioner as a Room Heater This Winter | Save Up to 40% on Bills
Most people think air conditioners are just for cooling, but that’s not true anymore. Modern inverter and split ACs can also work as efficient room heaters during winter. If your AC remote has a “HEAT” mode or a sun icon, you’re sitting on an energy-saving feature that can keep your home warm without buying a separate heater.
How to Use Your AC as a Room Heater
Using your air conditioner for heating is simple. Press the Mode button on your remote until you see the sun symbol or HEAT displayed. Once activated, set the temperature between 24°C and 26°C for the best balance of comfort and energy efficiency. Don’t worry if the air feels cool at first—your AC needs about a minute or two to reverse its operation and start blowing warm air.
To get the most out of your AC heater, follow these tips:
- Keep all doors and windows closed to trap the heat inside.
- Turn on swing mode to distribute warm air evenly.
- Avoid setting the temperature above 27°C, as it consumes extra power without adding much warmth.
Why Heating With AC Saves Energy
The secret is in heat pump technology. Instead of generating heat like traditional room heaters, inverter ACs transfer warmth from the outside air to the inside. This process makes them 30–40% more energy-efficient compared to standard electric heaters. The result? Lower power bills and a comfortable home through the winter.
However, performance depends on your room’s insulation and size. Poorly sealed or oversized spaces will make the AC work harder and use more electricity. For best results, use your AC’s heating mode in smaller, well-insulated rooms.
With just a few settings, your air conditioner can double up as a cost-effective, energy-efficient heating system this winter.
