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.

"Hartman Brothers always comes through for us. The furnace quit working and they squeezed us in the same day. They diagnosed and fixed it quickly. We won't use anyone else!"

"Extremely pleased with their work! When I say I'm a picky customer, I really mean it (I'm a Training Manager for an HVAC manufacturer). These guys showed up precisely on time, were extremely courteous and professional, and did an outstanding job on my system. They were very careful moving the equipment to my mechanical room (not an easy task), did a very neat job on the install, and cleaned up so that everything was spotless when they left. I even gave them an opportunity to do a "shortcut" on my install, but they refused and said "that's not the way we do it." It was easy to tell that these techs took PRIDE in the work they were doing. I can't even begin to tell you how much I would recommend this small business from New Haven, IN to do any HVAC work. If you want a courteous, professional install at a reasonable price, call Hartman Bros!"

"Tech was polite, professional, knowledgeable and worked quickly to resolve the issue with my furnace. I inquired about the root cause of this recurring problem and he kindly explained what was occurring to prevent the furnace from igniting, and what he had done to resolve the current issue, which I appreciated very much! As always, I remain a happy Hartman Bros. customer!"
