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.

"Love these people! We bought a brand new furnace and ac a year ago. For some crazy reason something happened to the ac Sunday when it was 91 degrees . I had a service guy here Sunday and Monday... Vicky was fabulous through it all and the guys were wonderful. They ended up working after hours and got it all fixed... Thank you from the bottom of my heart and my puppies. We're cool again!!"
