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.

"Our AC went out and they sent someone out within a few hours and the problem was fixed quickly. With our service membership we also got a discount so the repair price was reasonable. I was very impressed with how quickly and professionally they fixed the problem especially in the middle of summer when they must get a lot of AC calls. Will definitely continue to use Hartman Bros."

"As always, Hartman Bros does service RIGHT! They are prompt, courteous, professional, clean and fairly priced for all services we've ever had completed. We were introduced to them in 1998 when we first used their services and have been faithfully returning for every Heating and Air need, including the building of 2 new homes. They are stellar performers providing excellence at a time when mediocrity has been touted as the norm in our society. They go well above and beyond in all they do."
