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 service was great as always. The 2 men who came to install my new furnace were very professional and took the time to explain what they were doing and showed me what the problem was with my old furnace. Thanks Mr Hartman for coming up North and for having a great crew."

"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."

"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."

"Great first impression with the receptionist who answered my call after the first ring! She was friendly, professional, and genuine... The service repair technician was professional and took time to explain the repair that he recommended to the A/C unit. He fixed the unit on the spot. Not only great service, but great people too. Thank you, Hartman Brothers!"
