Can Daikin AC be Used as a Heater?

Yes, a Daikin AC can be used as a heater, but not all Daikin AC models have this capability. Only those Daikin AC models that come equipped with a heat pump can be used for heating purposes. These heat pump models can both cool and produce heat as desired. When the heat mode is activated, the AC unit generates warm air to combat the cool outdoor air.

Advantages of Using a Daikin AC as a Heater

Using a Daikin AC as a heater offers several advantages:

  1. Space-Saving: It eliminates the need for a separate heating appliance, saving valuable space in your home or office.

  2. Energy-Efficient: The thermostat of a Daikin AC consumes less electricity compared to traditional heaters, resulting in lower energy costs.

  3. Increased Safety: Daikin ACs are typically installed at a height, making them less accessible to children, unlike many heating appliances.

  4. Year-Round Functionality: Using the AC as a heater ensures that the unit remains in good working condition throughout the year, maximizing its lifespan.

Technical Specifications and Considerations

When considering using a Daikin AC as a heater, it’s essential to ensure that the specific model you have is equipped with a heat pump. Here are some key technical specifications and considerations:

  1. Heating Capacity: Daikin heat pump models are available in a range of heating capacities, measured in BTU/h (British Thermal Units per hour) or kW (kilowatts). Choose a model with a heating capacity suitable for the size of the space you need to heat.

  2. Energy Efficiency Ratings: Look for Daikin heat pump models with high energy efficiency ratings, such as SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor), to maximize energy savings.

  3. Heating Temperature Range: Ensure that the Daikin heat pump model you select can effectively heat your space, even in the coldest outdoor temperatures. Check the minimum and maximum heating temperature ranges.

  4. Noise Levels: Consider the noise levels of the indoor and outdoor units, especially if the AC will be installed in a living or working space. Daikin’s advanced designs aim to provide quiet operation.

  5. Installation and Maintenance: Proper installation and regular maintenance are crucial for the optimal performance and longevity of your Daikin heat pump system. Consult with a certified Daikin installer or service technician for guidance.

By carefully considering these technical specifications and following the manufacturer’s recommendations, you can ensure that your Daikin AC effectively serves as a reliable and energy-efficient heater for your home or office.


In conclusion, using a Daikin AC as a heater can be a smart and practical choice, offering a range of benefits such as space-saving, energy efficiency, and increased safety. However, it’s essential to ensure that the specific Daikin AC model you have is equipped with a heat pump and is suitable for heating purposes. By understanding the technical specifications and taking advantage of Daikin’s advanced heat pump technologies and comprehensive support services, you can enjoy the comfort and convenience of a Daikin AC as both a cooling and heating solution.
