What to Know About C-Wire If you’re upgrading your HVAC thermostat, it’s a good thing to find out in advance if your existing system provides a c-wire. Today’s smart thermostats provide a great deal more options and convenience such as wifi connectivity and a bigger, brighter, multi-functional control screen. These improvements typically draw more electricity than the existing thermostat you’re replacing. The c-wire (“c” stands for “common”) is an important extra electrical wire that enables continuous 24-volt power to operate newer smart thermostats. If you don’t have one installed with your existing model, you’ll probably need to have it installed in order to adequately power the new unit.

"We purchased our home just a few days ago and the heat was not working, and we were in single digit temps in this area. Josh, our tech, came out and checked everything out and discovered it was a programming issue on the digital thermostat. He set it correctly and heat is now working. The level of service of Hartman is phenomenal! Vickie in the office deserves a big thank you as the house was at 45 when I called and she saw to it that we were worked into their busy service request schedule."
