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.

"Ked came on time for my semi-annual scheduled appointment, checked out the furnace and changed the filter. He spent a considerable amount of time trying to track and fix a problem with my smart hub, but stayed with it until we think it is fixed. This is the third HVAC system I have purchased from Hartman Brothers over the past 40 years and I have always been pleased with their service, product and personnel. That is why I still use them. Took them awhile to convince me the annual maintenance program is a good deal, but with all the electronics in the new systems, the system needs care and feeding from a professional! I am glad I finally listened!"

"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!"
