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.

"My experience was excellent. The furnace runs very quietly and before when it would come on and I was sleeping it came on so loud it would wake me up. I'm so pleased with Hartman Brothers. My AC stopped working I thought it had something to do with my thermostat but Hartman's checked things out and found out someone turned the power off in the garage."

"Hartman Brothers installed the HVAC system before we bought this home, and has always maintained it. When it was time to replace it after 32 years, we selected them to install & maintain this system as well."

"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."
