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 technician arrived as scheduled, was courteous at the door and asked if it was OK to come into the house, after which he put his booties over his work shoes. He (I wish I knew his name) seemed to complete his tasks efficiently, cleaned up his workspace and gave a thorough rendition of the condition of our AC unit. I appreciated his work and glad that we had the service contract. Great Job!"

"Every thing went well, even though he had bad news that the unit needed to be replaced due to the fact that the unit was 18 years old and the refrigerant used in the day was R22 that it cant be purchased because of government regulations, now we will see what the estimate will be. The technician seems to be knowledgeable and was very professional about his work."
