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.

"A heating unit in my barn had stopped working. This unit was originally installed by Harman Brothers years ago. Josh opened the unit up and within 30 minutes he found the problem and had it repaired."

"On Saturday, my water heater spewed lots of water in the utility portion of my garage. Unfortunately, my furnace was soaked. After my call to Hartman Bros., Darian arrived within the hour and dried out the furnace and re-started it. Hartman Bros. has been servicing my heating and cooling systems for over 30 years and have always been "johnny-on-the-spot" when I have had problems. I highly recommend them."
