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.

"Josh was very courteous and professional. He took the time to explain to me and show me what was going on inside the furnace. I felt really bad that we needed to call him out on a Sunday but with the inside of the furnace iced up our air just wasnt working and he got us up and running in no time"

"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!"

"My husband and I were very pleased with the quality of service we received today from Caleb. He worked very hard to figure out why our furnace wasn't working. He also cleaned the coils which provided us with better air quality. We are now enjoying a cozy warm home again. Thank you Caleb for a job well done."

"The staff is wonderful and the technicians are "top notch" at Hartman Brothers! I have used this company for the past 25+ years for all my regular maintenance checkups and repairs. I have never been disappointed with the quality of work by the Hartman Brothers service technicians. My most recent service tech was "Josh." Josh was very courteous and professional. I will continue to use Hartman Brothers for all my HVAC needs for years to come!"
