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.

"AMAZING customer service!! My a/c went out this weekend - yes, THIS weekend the hottest weekend of the year. I called the office and they were able to have a service technician out within 5 hours. The truck was a sight for hot and sore eyes for sure. He did a wonderful job finding and fixing the problem as quickly as possible. 10/10 highly recommend!!"

"Ked came on time for my semi-annual scheduled appointment, checked out the furnace and changed the filter. He spent a considerable amount of time trying to track and fix a problem with my smart hub, but stayed with it until we think it is fixed. This is the third HVAC system I have purchased from Hartman Brothers over the past 40 years and I have always been pleased with their service, product and personnel. That is why I still use them. Took them awhile to convince me the annual maintenance program is a good deal, but with all the electronics in the new systems, the system needs care and feeding from a professional! I am glad I finally listened!"

"Everything was competed as expected and my satisfaction. The service representative could have even arrived earlier than scheduled if I could have accommodated the time"

"We replaced a heat pump hvac system, got pricing from 4 hvac contractors. Lots of choices and levels but Hartman was head and shoulders above the others in cost and quality. They have experienced Technicians and great Owners, we highly recommend them!"
