Best Smart Thermostats Compatible with Renters & Portable AC Units (2025 Picks)

Why Renters Need Smart Climate Control

For homeowners, installing a smart thermostat is straightforward — they usually replace an existing wall thermostat. But for renters living in apartments, condos, or dorms, things get more complicated. Many apartments use:

✔️ Window or portable AC units
✔️ Baseboard heaters
✔️ Radiators with no central thermostat
✔️ Mini-split systems

In 2025, smart climate control isn’t just for homeowners. There are now smart thermostats, portable AC controllers, and plug-in devices that work perfectly in rental units — allowing renters to control temperature remotely, save energy, and even track usage.

Here are 5 of the best smart thermostats and controllers specifically designed for renters and portable AC units in 2025.
