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!!"
