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.

"I had just called in yesterday for a non-emergency plumbing repair and they were out first thing this morning! Brad was very professional and courteous and he got everything taken care of very promptly. He had to go get a part and was back faster than I thought he could be. Great job and I will call again for my plumbing as well as my HVAC needs."
