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 AC went out and they sent someone out within a few hours and the problem was fixed quickly. With our service membership we also got a discount so the repair price was reasonable. I was very impressed with how quickly and professionally they fixed the problem especially in the middle of summer when they must get a lot of AC calls. Will definitely continue to use Hartman Bros."

"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.""

"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!"

"The service was great as always. The 2 men who came to install my new furnace were very professional and took the time to explain what they were doing and showed me what the problem was with my old furnace. Thanks Mr Hartman for coming up North and for having a great crew."

"They were on time, cleaned up after themselves, and the quote they gave was exactly the amount charged. I would use them again and recommend them."

"My husband and I were very pleased with the quality of service we received today from Caleb. He worked very hard to figure out why our furnace wasn't working. He also cleaned the coils which provided us with better air quality. We are now enjoying a cozy warm home again. Thank you Caleb for a job well done."
