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.

"My experience was excellent. The furnace runs very quietly and before when it would come on and I was sleeping it came on so loud it would wake me up. I'm so pleased with Hartman Brothers. My AC stopped working I thought it had something to do with my thermostat but Hartman's checked things out and found out someone turned the power off in the garage."

"Josh was very courteous and professional. He took the time to explain to me and show me what was going on inside the furnace. I felt really bad that we needed to call him out on a Sunday but with the inside of the furnace iced up our air just wasnt working and he got us up and running in no time"
