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.

"Brian showed me what was wrong with my air conditioning unit and explained everything so I could understand. He spoke to Vicki at the office regarding a needed part that would have to be ordered. They could have slapped a generic part on, but it would have only been a short-term fix. Instead of taking the easy way out, they are getting the part made for my unit so it will stay fixed, and they are coming back to finish the job as soon as they have the part. Hartman Brothers is ethical, knowledgeable, friendly, and they do the job right! I highly recommend them!"

"Ked was my "usual" service tech for many years. He was always friendly & kind...and didn't mind letting my big dog say hi. He was always professional and efficient. I liked having the piece of mind in knowing my HVAC needs are met & running well. I have used their maintenance plan for many years now, and haven't been disappointed. Well, Caleb didn't disappoint either. He loved my "big boy" and had a great sense of humor. He was very thorough in servicing my air conditioner. I feel I get my money's worth from my maintenance plan each year. I love when they say, "Everything looks good, no problems. See you in the Fall.""
