An inverter AC can do more than cool your room during summer. If you own a heat and cool model, you can also use it to warm your home during winter. Learning how to use heat mode in inverter AC helps you stay comfortable when temperatures drop without needing a separate heating appliance.
Brands like Haier, Gree, Midea, and Dawlance offer different air conditioning models, including options with heating functions. However, not every inverter AC supports heating, so check your model’s specifications before using this feature.
In this guide, we’ll explain how to activate the heating function, choose the right temperature, and use your AC effectively during winter.
How to Activate Heating Mode
If your inverter AC supports heating, you can usually activate it through the remote control. Follow these simple steps to get started.
- Turn on the AC: Press the power button on your remote control
- Select Heat mode: Press the Mode button repeatedly until you see the sun symbol or the word “HEAT” on the display.
- Set the temperature: Choose a comfortable temperature, usually between 20°C and 24°C.
- Adjust the fan speed: Select Auto or a suitable fan speed for comfortable airflow.
- Wait for warm air: Give the AC a few minutes to start heating the room. Some models delay airflow to prevent cold air from blowing into the room.
These steps explain how to turn on an inverter heater using a typical AC remote. The exact process may vary depending on the manufacturer and model.
If your remote doesn't show Heat mode, check the user manual to confirm whether your AC supports heating.
Tips for Using Your AC During Winter
Using your AC correctly during winter can help maintain a comfortable indoor temperature. Follow these practical tips to get better results from the heating function.
Set a Comfortable Temperature
Avoid setting the temperature too high. A setting between 20°C and 24°C is a reasonable starting point for most rooms. If the room feels comfortable, there's no need to increase it further.
Keep Doors and Windows Closed
Warm air escapes through open doors and windows, making it harder for the AC to maintain the desired temperature. Close gaps where possible to reduce heat loss.
Use Auto Fan Mode
Auto fan mode allows the AC to adjust airflow according to the room's heating needs. This can help distribute warm air comfortably without requiring constant manual adjustments.
Clean the Air Filters
Dusty filters can restrict airflow and affect heating performance. Clean the filters according to the manufacturer's instructions to help your AC work efficiently.
Avoid Frequent Temperature Changes
Choose your preferred temperature and allow the inverter AC to maintain it. Frequently changing the settings can make the room less comfortable and may affect energy consumption.
Can You Use Any AC as a Heater?
You can turn your air conditioner into a heater only if it has a built in heating function. A heat and cool inverter AC uses a reversible refrigeration cycle to transfer heat indoors during winter.
To switch your AC from cooling to heating, select Heat mode using the remote control. If your AC only offers Cool, Dry, Fan, and Auto modes, it may be a cooling only model.
Before buying an AC for year round use, check its heating specifications and confirm that it supports operation in your area's winter temperatures.
How to Improve Heating Performance
If you want to use your inverter AC as a heater without unnecessary electricity consumption, keep these practical tips in mind.
- Choose the right temperature: Start with 20°C to 24°C and adjust according to your comfort.
- Use a suitable AC capacity: An AC that is too small for your room may struggle to maintain the desired temperature.
- Check outdoor unit clearance: Keep the outdoor unit free from obstructions so it can exchange heat properly.
- Allow defrost cycles: In cold and humid conditions, frost can build up on the outdoor unit. Your AC may temporarily pause heating to remove it. This is generally normal.
- Maintain your AC regularly: Proper servicing and clean filters help maintain airflow and heating performance.

Common Heating Problems and Solutions
Sometimes, the AC may not produce warm air immediately after you select Heat mode. Understanding the possible causes can help you resolve minor issues.
- AC blows cool air initially: Wait a few minutes for the heating cycle to begin. Some models need time to prepare before blowing warm air.
- Heat mode is unavailable: Check whether your AC model supports heating. Not all inverter ACs have this feature.
- Room takes too long to warm up: Check the temperature setting, clean the filters, and make sure the AC capacity is suitable for your room size. Poor insulation can also affect heating performance.
- Outdoor unit releases steam: This can happen during a defrost cycle in cold weather. It is generally normal and helps remove frost from the outdoor unit.
- AC stops heating temporarily: Your AC may be running a defrost cycle or may have reached the selected temperature. If heating does not resume, consult the user manual or contact an authorized technician.
