Smart control turns air conditioning from a box with a remote into part of your home. You can cool a bedroom before you get home, set schedules that match your working week, check what the system is doing while you’re away and, with some brands, see how much energy it uses.
The details vary by brand and even by model. The main question to ask before you buy is simple: is Wi-Fi built in, or does it need an adapter?

Features worth having
- Schedules. The single biggest comfort win. Cool the bedroom from 9 pm, switch off at 7 am.
- Energy monitoring. Toshiba’s Haori, Shorai Curve and Daiseikai list it, and LG’s DUALCOOL Premium has energy monitoring and a kW Manager to cap power.
- Smart modes. Samsung describes an AI Energy Mode in SmartThings that learns your patterns and switches to power saving; Samsung notes it may change set temperatures.
- Fault alerts. Being told about a fault early can stop a small problem becoming a big one.
- Multi-room control. One app for every indoor unit on a multi-split.
Voice control
Most brands connect to Amazon Alexa or Google Home through their own cloud service. You link the brand app to your voice assistant once, then use simple commands like “set the bedroom to 20 degrees”. Apple Home support is less common and often needs third-party hardware, so check before relying on it.

Home automation and tariffs
For more ambitious setups, air conditioning can be linked to platforms such as Home Assistant or to wider building controls, usually through the brand’s cloud or a dedicated interface. Useful automations include pre-cooling before an evening peak, running harder when solar panels are generating, and switching off when windows open.
If you’re on a time-of-use tariff, schedules alone can shift a lot of use into cheaper hours. See /air-conditioning-time-of-use-tariffs/ and /air-conditioning-solar-panels-guide/.
Security and reliability
A connected air conditioner is a device on your home network. Keep the app updated, use a strong Wi-Fi password and consider a separate network for smart devices. LG states a 5-year security update period from launch on its DUALCOOL Premium page, and it’s worth asking every manufacturer the same question. A unit that loses Wi-Fi still works normally from its remote.
What we do at installation
If you want app control, we check the Wi-Fi signal at each indoor unit at the site survey, include any adapter in your fixed-price quote and connect the system to your app at handover, so it works before we leave. For businesses, we can advise on central controllers for multi-room or VRF systems. See /air-conditioning-installation/ and /office-air-conditioning/.
Quick answers
Can I control my air conditioning from my phone?
Yes, with most current systems. Many wall units have Wi-Fi built in; others, such as the Toshiba Seiya and current Fujitsu/GENERAL wall units, need an optional adapter.
Does air conditioning work with Alexa?
Many brands link to Alexa and Google Home through their own app, including Daikin Onecta, Panasonic Comfort Cloud and Toshiba’s app. Check the specific model.
Can an existing system be made smart?
Often, yes, with the manufacturer’s Wi-Fi adapter if one is made for your model. We can check compatibility from the model number.
