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 signed up for a service plan, as I’m not much of a handyman myself. They had a variety of payment options with the service plan, so I was able to start monthly payments, which works best for me. Our service person was polite, and he explained everything in terms I had no problems understanding. I had an additional issue with an attic duct being chewed through. He got up there and got pictures right away so they could put together an estimate. Same visit, no hassle. And because of the service plan, there was no charge for the system check. I just let him in, showed him around, and he worked his magic. No regrets here. There’s a very good chance I’ll just keep up this service plan for the entire time I own my home."

"The staff is wonderful and the technicians are "top notch" at Hartman Brothers! I have used this company for the past 25+ years for all my regular maintenance checkups and repairs. I have never been disappointed with the quality of work by the Hartman Brothers service technicians. My most recent service tech was "Josh." Josh was very courteous and professional. I will continue to use Hartman Brothers for all my HVAC needs for years to come!"

"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!!"

"I have called Hartman Bros twice for problems with my home air conditioning. Both times I felt that the pricing was fair. I appreciate that they seem to start with trying to repair and not jump to replace."
