FAQ

Why is my Nest fan always on?

If the nest thermostat fans keep running even when heating and cooling are turned off, you probably don’t have a c wire  and you’ll definitely  need it to fix the problem. The c wire supplies your nest with consistent 24 volts.

When there is no C wire, your thermostat can have issues with controlling your system

Other times, your service technician  may have used the G wire as the c wire and twisted it on any other wire. That could also cause the fan to constantly run. The long term solutions is to add a C wire or get a nest power connector( which much easier and inexpensive or many installations)
