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.

"Hartman Brothers installed the HVAC system before we bought this home, and has always maintained it. When it was time to replace it after 32 years, we selected them to install & maintain this system as well."

"Our air conditioning went out today. My husband called Hartman Brothers. They were here within 30 minutes. I can’t remember the guy’s name but he was very nice and did a great job! Hopefully we won’t have any more problems but if we do, we’ll call Hartman’s."
