Can Your Air Conditioner Actually Heat Your Home?

Yes, many air conditioners can also heat your home, especially those with reverse cycle or heat pump functions. They use a reversing valve to alternate between cooling and heating, so your existing unit might already handle both without needing anything extra. If you live in London and want professional installation or maintenance, RightAir Solutions provides expert guidance for ensuring your system works efficiently year-round.

What Should You Check to Know If Your AC Can Heat?

Signs Your AC Can Also Heat

  • Check your remote control or wall panel for a “HEAT” or “REVERSE CYCLE” setting.

  • Look at the outdoor unit or manual for words like “heat pump” or “reverse cycle.”

  • Search your model online. Mitsubishi Electric and Daikin often list full features, especially for dual mode systems.

Which System Types Usually Include Heating?

  • Split Systems: Good for individual rooms and usually support heating and cooling. They include an indoor air handling unit that manages airflow.

  • Ducted Reverse Cycle Systems: Heat and cool your whole home from a central unit, perfect for off season use.

  • Portable Heat Pump Units: Easy to move and ideal for renters or small spaces.

Pro Tip: Keep your thermostat steady between 18°C and 22°C to avoid unnecessary energy use and system cycling.

How Do You Switch Your AC to Heating Mode?

Mode Change Instructions

  • Press the “Mode” button until “HEAT” appears.

  • Wait two to five minutes for the compressor to start. A short delay is normal.

  • Some cold air might blow at first. This is just part of the system warming up.

How Should You Set the Temperature?

  • Keep your thermostat heat setting between 18°C and 22°C during cold months.

  • Leave the temperature steady instead of changing it often. This supports better temperature stabilisation and lowers system cycling.

  • Set your ceiling fan on low fan speed to gently bring warm air down and improve circulation patterns.

Note: Avoid using “Auto” mode in winter. It might flip between cooling and heating unexpectedly.

What Are Easy Ways to Make Heating with AC More Efficient?

Everyday Efficiency Tips

  • Clean or change filters monthly during winter to keep air flowing well and maintain runtime efficiency.

  • Use a programmable thermostat to schedule heating sessions based on room usage.

  • Make sure the outdoor unit stays free from debris to allow better airflow.

Add Ons That Help

  • Fit thermal curtains or insulation film on windows to improve indoor heat retention.

  • Use off peak energy tariffs if your provider offers them to reduce overall heating costs.

  • Monitor usage with your unit’s companion app and adjust settings based on performance.

For London homeowners looking for premium installation or upgrades, our team at RightAir Solutions can ensure your heat pump or AC system delivers optimal comfort and efficiency.

Pro Tip: Use ceiling fans on low speed to circulate warm air effectively without raising energy costs.

What Are Common Myths About Heating with Air Conditioning?

What People Often Get Wrong

  • “ACs stop working in freezing weather.”

    • Newer models from Daikin and Mitsubishi Electric work in temperatures as low as minus 15°C, making them suitable for UK climate conditions.

  • “It’s too pricey to heat with AC.”

    • With a good COP and inverter compressor, heating can actually be economical.

  • “Warm air from AC is bad for health.”

    • If your allergy filters are clean, your system should provide good airflow quality.

The Facts That Matter

  • Units with a Coefficient of Performance (COP) above one deliver more heat than the energy they use.

  • Inverter technology reduces energy draw by adjusting to room needs.

When Should You Get Help or Consider an Upgrade?

Signs Something Isn’t Right

  • The unit stays cold even when on heat mode.

  • Heating takes ages or cuts in and out too often.

  • Your bills keep climbing even with normal use.

Options That Can Help

  • Consider a modern inverter heat pump for improved heating capacity.

  • Add a backup heater or dual source system if winters are especially cold.

  • Get a qualified HVAC technician to carry out a detailed check.

  • Look into the UK heat pump grant if you’re planning a home retrofit.
