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.

"The repairman noticed a problem with the condenser and took care of it. I was unaware of the problem because I cannot ambulate to the basement at this time."

"I absolutely loved the service we received from Hartman Brothers. They gave us an appointment right away, and the technician knew what our issue was based on my husband's conversation with the scheduler. As a result, he came prepared to fix our problem. The technician was also very nice and courteous. I would recommend everyone to give them a call for all your HVAC needs. Thanks Hartman for a job well done!"
