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.

"AMAZING customer service!! My a/c went out this weekend - yes, THIS weekend the hottest weekend of the year. I called the office and they were able to have a service technician out within 5 hours. The truck was a sight for hot and sore eyes for sure. He did a wonderful job finding and fixing the problem as quickly as possible. 10/10 highly recommend!!"

"On Saturday, my water heater spewed lots of water in the utility portion of my garage. Unfortunately, my furnace was soaked. After my call to Hartman Bros., Darian arrived within the hour and dried out the furnace and re-started it. Hartman Bros. has been servicing my heating and cooling systems for over 30 years and have always been "johnny-on-the-spot" when I have had problems. I highly recommend them."

"Interviewed three companies for new HVAC install and Rick Hartman as the owner stood out in the interview process. For the installation itself, Darian and partner flawlessly executed the install. Best choice. No misunderstandings. Everything is working perfectly."
