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.

"I've had Hartman's install new Bryant H/Vac systems in 2 houses now and I've been pleased with the outcome at both houses. They are local, on time and reasonably priced. I've had a couple minor problems and Hartman Bros treated me fairly and took care of the issues. You don't buy 2 complete H/Vac systems from someone you don't trust or has treated you unfairly."
