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.

"They worked me in early. Inspected and found the problem quickly. Explain the issues thoroughly and did not attempt to see me parts and services I did not need. They got the heat going temporarily and hope to have needed parts in a couple days."

"We purchased our home just a few days ago and the heat was not working, and we were in single digit temps in this area. Josh, our tech, came out and checked everything out and discovered it was a programming issue on the digital thermostat. He set it correctly and heat is now working. The level of service of Hartman is phenomenal! Vickie in the office deserves a big thank you as the house was at 45 when I called and she saw to it that we were worked into their busy service request schedule."

"We reached out to Hartman Brothers as our previous place was actually rude and acted like didnt care as we had an issue with the AC. Our systems at that point were about 14 years old. We got a quote from previous place and i about fell off my chair. Called Hartman Brothers and asked if they could provide a quote for us on both and in AC alone. Super impressed as Rick came out next morning. Looked at what we currently had and that same day had a complete quote to us. We were scheduled for May 26 install however they had a cancellation and came out May 17. Both techs were super amazing. Talked with us with everything and answered all of our questions. They came out a little before 8am and everything was installed and working by 2pm. Cleaned up their stuff ( which was great as we have 3 dogs). Never have we experienced this type of professionalism from any company. We are all so pleased with Hartman Brothers including Vicki in the office. She was great helping me and explaining the maintenance agreement. If you ever need a great team you wont be disappointed with Hartman Brothers ! We thank you all for helping us and doing a great job. It was also great we kept it local as well. Glad to be a part of the Hartman Brothers family now ! Thank you again."

"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."
