Encountering Smart Thermostat Problems

Encountering Smart Thermostat ProblemsSmart thermostats give you the flexibility to control your HVAC system with any mobile device or your voice and can help you reduce energy costs significantly. Despite all their technological advances, they can experience certain problems. Here’s a look at the common smart thermostat issues.

HVAC System Malfunction

A power stealing thermostat uses power from the HVAC system’s control circuits to charge its internal battery, which in turn powers the thermostat. Remember, smart thermostats are usually equipped with large full-color touchscreens that need a constant and reliable source of power.

Your HVAC system isn’t designed for power stealing. As a result, a power stealing smart thermostat may make your HVAC system run improperly or even shut it down.

The best solution is to have an HVAC professional run a C wire. This separate 24-volt wire supplies continuous and reliable power to your smart thermostat.

Low Battery Level

Your smart thermostat may suddenly go out of battery. A faulty software update may be to blame. A wiring problem might also cause your battery not to charge properly. Unplugging the device and then manually restarting it could help. If it doesn’t, you’ll need to contact a professional.


Occasionally, your smart thermostat may go offline. As a result, you won’t be able to control it using the mobile app. Your internet connection could be down. Rebooting the router could help. A failed software update and loss of power could also be responsible for the problem. In such instances, you’ll need to restart the thermostat manually. If the problem persists, consider consulting an HVAC specialist.

Smart thermostat issues can cause sudden or subtle changes to the performance of your heating and cooling system. Therefore, it’s always best to call in a professional if you’re unable to address the problems on your own.
