How to control your air conditioner from your phone
You are on the way home in a heatwave and the flat has been baking all day. If the air conditioner listens to your phone, the bedroom is already cool when you open the door. If it does not, a small infrared bridge can teach an old unit new tricks.
Getting connected, then the habits that keep the unit running well, then air conditioner apps. Settings, cleaning and service intervals differ by model. Follow your unit’s manual, and leave refrigerant and electrical work to a qualified technician.
Wi-Fi unit or infrared bridge
Many newer units connect to Wi-Fi through the maker’s app. Older units that only take a handheld remote can work with a smart infrared remote that copies its signals. Compare the options in air conditioner apps.
Schedule, do not blast
A schedule that switches the unit on a little before you arrive is gentler than running it at full power once you are home. Close the curtains on the sunny side during the day.
Bring it into the smart home
Some apps work with voice assistants and home hubs, so the air conditioner can switch off when the last person leaves. See how to start a smart home and smart home apps.
Keep it clean
A dusty filter means weaker airflow. Set a reminder to clean it as often as the manual says, and book a service for anything beyond the filter. See how to keep track of home maintenance.

|---|---|---|
| 1. Check the unit | built-in Wi-Fi or not | pick the right route |
| 2. Connect | maker’s app or smart IR remote | control from anywhere |
| 3. Schedule | on before you get home | cool room, no waiting |
| 4. Right mode | cool, dry, fan, as the manual says | comfort without waste |
| 5. Filter reminder | clean as the manual says | better airflow |
